Fasting Mimicking Diet

The fasting mimicking diet (FMD) was at the center of this year’s anti-aging conference in Las Vegas. This was the 25th Annual World Congress on Anti-Aging Medicine in Las Vegas, Dec. 14-16, 2017. Dr. Valter Longo, PhD reviewed some of the research he had done on longevity in yeast cells, worms and mice.

Fasting mimicking diet relevant in humans

Dr. Longo pointed out that this type of research has relevance in humans. If there was a cure for cancer, heart disease, stroke and diabetes, we would live 13 years longer. But if we stimulated longevity with this pulsed calorie restricted diet, we would live on average 30 years longer. There is a rare genetic abnormality where people are deficient for IGF-1, a growth factor produced in the liver. These genetically IGF-1 deficient people live longer and do not develop cancer. Observations like these and detailed mouse experiments inspired Dr. Longo to develop a new diet plan. Patients would receive a fasting mimicking diet on 5 days per month. The rest of the month would consist of a normal, balanced diet. 5 days of the month the person would consume a low 800-calorie diet. This is enough to ensure adherence to the diet, but low enough to lead to enormous metabolic changes including youth-preserving stem cell stimulation.

Clinical Application of fasting mimicking diet in cardiovascular health

Dr. Joel Kahn, Prof. of Medicine at the Wayne State University School of Medicine lectured later that day. He is also the Director at the Kahn Center for Cardiac Longevity. His talk was entitled “The Fast Track to Slow Cardiac Aging: Fasting &Targeted Nutrition”. He mentioned that a fasting mimicking diet was a powerful tool in cardiology to prevent heart attacks and hardening of arteries. He explained in detail the complex aging pathways that involve three components, IGF-1, mTOR and PKA. When lifestyle choices stimulate these genetic markers, accelerated aging is a consequence. But with the inhibition of those markers longevity can happen. He added that researchers looked at heart cells, where the same principles apply. Dr. Kahn pointed out that the basic research of Dr. Longo enables clinicians to see positive results in patients who follow caloric restriction for 5 days in a month on a regular basis.

How does the fasting mimicking diet work?

It is best to let one of the users of this diet explain how it works. Once per month you eat calorie-restricted food with only 800 calories per day and you follow this regimen for 5 days. Some patients receive 1100 calories for the first of these 5 days, if they have difficulties switching from normal food to the boxed food. Dt. Longo has developed boxed food, called ProLon (from L-Nutra). ProLon stands for “pro longevity”. Dr. Longo and Dr. LaValle mentioned at the conference that these prepared meals make it a lot easier for patients to stick to the low calorie diet. Three hundred dollars for the boxed food for 5 days are a stiff price, and this may well be out of reach for you.

Alternative way to make your own 800 calorie food at home

Nevertheless, this should not stop you. You can look at the ingredients online and copy the boxed food by creating your own balanced 800 calories per day food at home. It is true: you have to do some research! But counting calories and finding information about the caloric content of food on the Internet is not difficult. And preparing these very, basic, small and simple meals does not require a degree in nutrition. Here is another testimony from a user of the fasting mimicking diet.

Effect of the fasting mimicking diet on the metabolism

In the past it was thought that only ketogenic diets or periods of fasting would trigger longevity genes. But the basic research of Dr. Longo and others has shown that a low calorie diet for only 5 days can achieve the same thing. Longevity genes are activated; the negative aging pathways including IGF-1, mTOR and PKA are suppressed. The immune system gets activated from this. It also  leads to lowering of LDL cholesterol, triglycerides, blood pressure, insulin resistance, and diabetes improves. With the fasting mimicking diet the stomach sees some food, but the cells are fasting. According to Dr. Kahn this combination down regulates the body’s key nutrient-sensing pathways, which activates cellular regeneration and rejuvenation.

Clinical observations

Dr. Khan observed a high compliance rate with 3 cycles of the fasting mimicking diet. 94% of a group of patients were compliant over 3 months. Mild fatigue, mild headaches and mild weakness were present, but improved with each cycle. In addition to the above findings Dr. Khan found that there was weight loss, abdominal fat loss and waist circumference loss. There was also a reduction in IGF-1 levels, a reduction of the C-reactive protein and stimulation of stem cells.

Inflammation reduced, autoimmune diseases improved

The reduction of the C-reactive protein proves that semi-fasting reduces inflammation. The finding of stimulation of stem cells explains that regenerative processes can take place. Pain disappears, people report more energy and are generally feeling better.

There are other clinical findings. The positive effects from following the fasting mimicking diet last for several months. Also, when patients are on chemotherapy for cancer, the FMD will protect the healthy cells from the side effects of chemotherapy.

Dr. Kahn and Dr. LaValle noted that autoimmune disease responded to FMD. This was shown in both animal experiments using mice and in clinical case reports. Dr. LaValle described a 46-year old former Olympic athlete swimmer who had multiple sclerosis. After FMD she lost all of her muscle aches and cured her optic neuritis. This was something conventional medicine could not do for her.

Clinical applications of fasting mimicking diet

Here are some of the conditions that will respond to it.

  • Obesity, because of the weight loss effect
  • Diabetes: insulin resistance becomes lower and blood sugar levels drop.
  • High blood pressure reduced: many patients were able to reduce their medications or discontinue them
  • Prevention of heart attacks and strokes
  • Pain conditions will improve as all kinds of pain disappears, an effect for which at this point is no explanation
  • Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
  • Prevention of heart attacks because of reduction of LDL, triglycerides and CRP
  • Cancer cure rates improved by protecting normal cells and bone marrow
  • Longevity improved in mice with a 3-fold increase of their life span. Telomere length in humans was increased. Increased stem cells will find defective areas that need repair. This effect will open up a new chapter in medicine.

Maintaining the achievements of the fasting mimicking diet

At this point the implications of this new approach to weight loss and metabolic rejuvenation can only be estimated.

Limiting calories for 5 days triggers a metabolic change, which is permanent. You can experience the full effect of this rejuvenating low calorie treatment. You can do it every month without having to fear vitamin or mineral deficiencies.

Here is another link to the website of Dr. Axe where the fasting mimicking diet is also recommended.

Conclusion

The 25th Annual World Congress on Anti-Aging Medicine in Las Vegas, Dec. 14-16, 2017 had a new theme. Several talks dealt with the fasting mimicking diet (FMD). It is a calorie-reduced diet for 5 days in a month that will reset your metabolism. But it will also stimulate your stem cells and can heal autoimmune diseases. If you need chemotherapy for cancer, it protects your bone marrow and improves cancer cure rates. The interesting thing is that the effects of this low calorie treatment persist permanently for many months.

With the help of this diet longevity has been shown in mice; there has been a threefold life expectancy boost. Smaller trials in humans have shown telomere lengthening and stem cell stimulation. It is too early to say what the long-term effects will be for humans. But you can treat yourself with the FMD for 5 days of every month on an ongoing basis. The other days of the month you are eating a normal diet. This will ensure that your metabolism stays in top shape.

A healthier and longer life

Practical applications for the FMD are huge. Patients with obesity, diabetes and pain conditions all benefit from this. High blood pressure drops. There will be prevention of heart attacks, and there is improvement in patients with autoimmune diseases. There is better cancer survival when on the FMD. Finally there is a strong possibility that you will live longer, but also stay healthier on this intermittent calorie restricted diet.

As Dr. LaValle said: it is “fasting with food”, and Dr. Kahn added: “Eat less, live more!”

Relaxation Reduces Inflammation

Relaxation can calm your mind, but new research has shown that relaxation reduces inflammation as well.

This article is based on a research paper in Frontiers in Immunology in June of 2017.

It concentrated on the calming effect of meditation on the nuclear factor kappa B (NF-κB), which causes inflammation. We know that overstimulation of the sympathetic nervous system activates the inflammatory pathway by expressing the genes responsible for NF-κB. These authors showed that the reverse is true also, namely that  meditation suppresses inflammation.

This metaanalysis of 18 research papers included 846 participants.

Here are brief summary findings of these 18 studies. Note that diverse relaxation methods had very similar results on the genes expressing inflammatory markers.

1. Qigong practitioners

First of all, a group of Qigong practitioners had 132 downregulated genes and 118 upregulated genes when compared to non-meditating controls. Meditation strengthens the immune system and delays cell death.

2. Sudarshan Kriya yoga

Also, one form of yoga breathing is Sudarshan Kriya yoga. Subjects who practiced this form of breathing yoga for 1 hour per day did not have the stress-related response on white blood cells. In contrast, the controls who did not meditate this way showed no change in the white blood cell response to stress. Those practicing yoga had a strengthened immune system. The meditators also showed strengthening of genes that inhibit cell death.

3. Chronic lymphocytic leukemia

Furthermore, eight patients with chronic lymphocytic leukemia were practicing the “seven yoga breathing patterns”; the popular Indian yoga teacher, Swami Ramdev, developed these. Those patients practicing the breathing yoga technique activated 4,428 genes compared to controls. They showed an up to twofold upregulation, which strengthened their immune system.

4. Loneliness in older people

Another study noted that loneliness in older people causes inflammation, morbidity and mortality. 55-85 year old volunteers were taking a course of mindfulness-based stress reduction. The researchers wanted to find out whether it was due to increased inflammation that older people were more susceptible to disease. The physicians tested blood mononuclear cells for genome-wide transcriptional profiling. Those older persons who had reported loneliness had more transcription factors for nuclear factor kappa B (NF-κB) than controls without feelings of loneliness. After an 8-week course those who no longer felt loneliness had a reversal of proinflammatory gene expression. The genes that had changed expression were located on monocytes and B-lymphocytes; these are cells of the immune system.

5. Care workers for patients with mental health problems

Care workers who looked after patients with mental health problems or chronic physical problems often have stress-induced chronic inflammation markers in their blood. A study involving 23 caregivers used a practice of Kirtan Kriya Meditation (KKM) assisted by an audio recording every day for 8 weeks. The subjects filled in questionnaires for depression and mental health before and after the 8-week trial. Physicians also took blood samples for transcriptional profiling before and after the KKM trial.

Meditation effects genes and reduces inflammation

The KKM meditation group had significantly less depressive symptoms and showed improvements in mental health. There were down-regulations in 49 genes and up-regulations in 19 genes compared to the controls. The pro-inflammatory NF-κB expression showed a decrease; the anti-viral gene expression showed an increase. This was measured using the IRF-1 gene. This gene controls the expression of the interferon-regulatory factor 1 (IRF-1 gene), which controls the immune response to viral infections. The interesting observation here was that a time of only 8 weeks of meditation was able to reduce inflammatory substances in the blood and could activate the immune system to fight viruses better. Further tests showed that it was meditation that stimulated the B cells and the dendritic cells.

6. Younger breast cancer patients

Younger breast cancer patients taking a mindfulness meditation course: Another study involved younger stable breast cancer patients after treatment that also had insomnia. Patients with both breast cancer and insomnia often have a lot of inflammatory markers in the blood. In a study with 80 patients 40 underwent treatment with Tai-Chi exercises, the other group of 40 with cognitive-behavioral therapy. Tai-Chi exercises reduced IL-6 marginally and TNF (tumor necrosis factor) significantly. There was a 9% reduction with regard to the expression of 19 genes that were pro-inflammatory; there was also a 3.4% increase with regard to 34 genes involved in regulating the antiviral and anti-tumor activity in the Tai-Chi group when compared to the cognitive-behavioral therapy group.

Measurable results of mindfulness meditation course

While cognitive therapy has its benefits, the winner was the Tai-Chi group where there was down-regulation of 68 genes and up-regulation of 19 genes. As in the prior study there was a decrease of the pro-inflammatory NF-κB expression, which reduced the inflammatory response.

7.  Study with fatigued breast cancer patients

In another breast cancer study with fatigued breast cancer patients the patients practiced 3 months of Iyengar yoga. After 3 months of yoga 282 genes showed up-regulation and 153 genes showed down-regulation. There was significant lowering of the expression of NF-κB. This suggests a lowering of inflammation. At the same time questionnaires showed that the fatigue factors experienced a reduction 3 months after initiating yoga exercises.

8. Mindful meditation used in younger breast cancer patients

A group of 39 breast cancer patients diagnosed before the age of 50 received six weekly 2-hour sessions of mindful awareness practices (MAP). This program is very suitable for cancer survivors. In addition to the group sessions the patients also did daily exercises of between 5 minutes and 20 minutes by themselves. The control group consisted of patients on a wait list. The investigators used several psychological measure (depression and stress) and physical measures (fatigue, hot flashes and pain) to assess their progress. Gene expression in the genome and inflammatory proteins were measured at baseline and after the intervention.

Effects of mindful awareness practices

Mindful practices showed clear benefits: they reduced stress, and sleep disturbances, hot flashes and fatigue showed improvement. Depression also shoed a marginal reduction. There were 19 pro-inflammatory genes that were mad ineffective, but not in the control group that did not do mindful practices. Gene tests revealed that transcription factor NF-κB had significant down-regulation. Conversely the anti-inflammatory glucocorticoid receptor and the interferon regulatory factors showed higher values. Genes with down-regulation came from monocytes and dendritic cells while genes with up-regulation came from B lymphocytes.

9. Telomerase gene expression

Lifestyle modification changes telomerase gene expression: 48 patients with high blood pressure enrolled in an extensive lifestyle program teaching them about losing weight, eating less sodium, exercising, adopting a healthy diet and drinking less alcohol. The other choice was to use transcendental meditation (TM) combined with health education with weekly sessions for 4 months. It turned out that both programs led to an increased expression of telomerase genes. Both groups did not show telomerase changes, but the authors stated that the observation time was too short for that to occur. The extensive health education program turned out to be better for patients with high blood pressure as it decreased the diastolic blood pressure more and resulted in healthier lifestyles.

10. Older patients with insomnia

Mind-body interventions for older patients with insomnia: Examiners divided a sample of 120 older adults with insomnia into two groups. They treated one group with cognitive-behavioral therapy (CBT), the other group with Tai Chi. The control group consisted of a group of people participating in a sleep seminar. 4 months after the intervention the CBT group had a significantly reduced C-reactive protein (CRP). The pro-inflammatory markers were lower in both groups after 2 months and in the Tai Chi group this remained low until 16 months. Gene expression profiling showed that CBT downregulated 347 genes and upregulated 191 genes; the Tai Chi group had downregulated 202 genes and upregulated 52 genes. The downregulated genes were mostly inflammatory genes while the upregulated genes controlled mostly interferon and antibody responses.

11. Patients with bowel disease

19 patients with irritable bowel syndrome (IBS) and 29 patients with inflammatory bowel disease (IBD) were treated with a relaxation response-based mind-body intervention. This consisted of 9 weekly meetings, each lasting 1.5 hours and practices a home for 15-20 minutes. The participants were taught breathing exercises and cognitive skills designed to help manage stress. At the end of the mind-body intervention and at a follow-up visit 3 weeks later participants of both the IBS and IBD groups scored higher in quality of life and lower in the level of anxiety they had before. They had reduced symptoms of their conditions.

Results of relaxation response-based mind-body intervention on IBS patients

The IBS group showed an improvement in 1059 genes. These were mostly improvements in inflammatory responses, in cell growth, regarding proliferation, and also improvements in oxidative stress-related pathways. The IBD group showed improvements in 119 genes that were related to cell cycle regulation and DNA damages. Other genetic tests showed that NF-κB was a key molecule for both IBS and IBD. The main finding was that relaxation response-based mind-body intervention was able to down regulate inflammation in both IBD and IBS.

12. Caregivers for Alzheimer’s patients receiving a course of MBSR

25 caregivers participated in a course of mindfulness based stress reduction (MBSR). Using 194 differently expressed genes the investigators could predict who would be a poor, moderate or good responder to the MBSR intervention. These genes related to inflammation, depression and stress response. 91 genes could identify with an accuracy of 94.7% at baseline whether the person would receive psychological benefits from the MBSR program.

13. Higher state of consciousness in two experienced Buddha meditators

Genetic tests showed, similar to the description of other cases that genes affecting the immune system, cell death and the stress response experienced stimulation. EEG studies in both individuals during deep meditation were almost identical with an increase of theta and alpha frequency ranges.

14. Rapid gene expression in immune cells (lymphocytes) in the blood

One study used gentle yoga postures, meditation and breathing exercises. 10 participants recruited at a yoga camp had yoga experience between 1.5 months and 5 years. Their response resulted in 3-fold more gene changes than that of controls. Otherwise the findings were very similar to the other studies.

15. Genomic changes with the relaxation response

The relaxation response (RR) is the opposite of the stress response.  One study examined how various modes of entering into the relaxation response like yoga, Qi Gong, Tai Chi, breathing exercises, progressive muscle relaxation, meditation, and repetitive prayer would lead to beneficial gene effects. As in other studies inflammation was reduced and the immune system was stimulated from the relaxation response. This was verified with detailed gene studies. The authors noted that different genes were activated in people who had done long-term RR practice versus people who practiced RR only for a shorter time. There were distinctly different gene expressions.

16.  Energy metabolism and inflammation control

Relaxation responses beneficial for energy metabolism and inflammation control: Experts with experience in RR were compared with a group of novice RR practitioners. Experts and short-term practitioners expressed their genes differently at baseline. But after relaxation both experts and novices had gene changes in the area of energy metabolism, electron transport within the mitochondria, insulin secretion and cell aging. The upregulated genes are responsible for ATP synthase and insulin production. ATP synthase is responsible for energy production in the mitochondria and down regulates NF-κB pathway genes. Inflammation was reduced by these changes. All these beneficial gene changes were more prominent in expert RR practitioners. Other beneficial changes noted were telomere maintenance and nitric oxide production in both expert and novice RR practitioners.

17. Relaxation changes stress recovery and silences two inflammatory genes

Mindfulness meditation changes stress recovery and silences two inflammatory genes: Experienced meditators were tested after an intensive 8-h mindfulness meditation retreat workshop. Two inflammatory genes were silenced by mindfulness meditation compared to controls. Other genes that are involved in gene regulation were found to be downregulated as well. These experienced meditators had a faster cortisol recovery to social stress compared to controls.

18. Vacation and meditation effect on healing from disease

This last study investigated the effect of a 6-day holiday retreat. One group was offered a 4-day meditation course, one group was the control group just holidaying and the third group was an experienced meditation group who also took the retreat meditation course. Depression, stress, vitality, and mindfulness were measured with questionnaires. All groups were positively changed after the holiday and remained this way at 1 month after the retreat. 10 months after the retreat novice meditators were less depressed than the vacation control group. At the center of the experiment was the gene expression study.

Effects of holiday and meditation

390 genes had changed in all of the groups. The authors assumed that this was due to the relaxation experience of the retreat. The genes involved related to the stress response, wound healing, and injury. Other genes measured inflammation (control of tumor necrosis factor alpha). Another set of genes measured the control of protein synthesis of amyloid beta (Aβ) metabolism, which causes Alzheimer’s disease and dementia. All groups had markers that indicated less risk of dementia, depression and mortality, which was likely due to the relaxation from the retreat.

Relaxation Reduces Inflammation

Relaxation Reduces Inflammation

Conclusion

This study is a meta-analysis of 18 research papers. The authors found that very different approaches to relax the mind have fairly consistent universal effects on reducing inflammation. Most of this work was done with genetic markers. No matter what type of relaxation method you use, you will have beneficial effects from it. But the beneficial effect is not only strengthening the immune system, it also improves sleep, depression, anxiety and blood pressure. In addition it is improving your stress response, wound healing, risk of dementia and it reduces mortality. We don’t quite understand all of the details yet.

What is definitely documented is the effect of the mind-body interaction. It also points clearly to the relaxation response from meditation and similar relaxation methods. This has been proven beyond any doubt through genetic tests.

Breast Cancer Risks

Dr. David Zava, PhD gave a talk on breast cancer risks. His presentation took place at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended. The detailed title was: “The Role of Hormones, Essential Nutrients, Environmental Toxins, and Lifestyle Choices on Breast Cancer Risk”.

He pointed out that both estrogens and progesterone are safe hormones, as long as the doctor does not overdose them and keeps a hormone balance. Unfortunately many women in menopause have too much estrogen on board as the ovaries are still producing them, but there is a lack of progesterone, the moderating hormone that makes estrogen safe.

In the following I am summarizing Dr. Zava’s talk with regard to the essential messages, but leave away much of the highly technical detail of the presentation. This would dilute the message of this blog. I will include a few links for those who wish to read more details about the topic.

Balance between estrogen and progesterone

Most of her life a woman is used to cyclical hormone changes between estrogen and progesterone. When a woman no longer ovulates in premenopause and menopause there is a surplus of estrogen and a lack of progesterone. Having no ovulation means that there is no corpus luteum developing, which is where in the past progesterone production took place. This creates a disbalance where estrogen is dominating; it is called “estrogen dominance”.

This is a dangerous hormone disbalance, because the breast ducts experience a growth stimulus, but the modifying, calming effect of progesterone is missing. Mixed into this is that the stress hormone, cortisol also can make the effect of estrogen worse. On the other hand Dr. Zava showed slides from studies documenting replacement of missing progesterone with a skin progesterone cream (percutaneous bioidentical progesterone cream).

Progesterone concentration in breast lumps after progesterone cream applications

Plasma and breast tissue concentration of progesterone were measured in 40 premenstrual women. The diagnoses were breast lumps and the physicians arranged surgery for them. One group received progesterone cream treatment for 10 to 13 days; the other group was the placebo group. At the time of surgery the plasma (blood) values of progesterone were the same, but progesterone levels in breast tissue were more than 100-fold higher than the values from the placebo group who had received a neutral skin cream. The same experiment also showed that progesterone reduced the number of proliferating epithelial cells (experimental progesterone group). Estrogen on the other hand led to an increase of the number of proliferating epithelial cells (placebo group).

Progesterone cream applied to breasts of premenopausal women

Another example that Dr. Zava gave was a study where 25 mg of bioidentical progesterone cream applied directly to breasts of premenopausal women increased breast tissue progesterone 100-fold, while blood concentrations of progesterone remained the same. Again progesterone decreased the breast stimulation by estrogen of normal epithelium cells.

How to measure progesterone levels

Dr. Zava who runs the ZRT laboratory spent some time to explain how to measure progesterone in a physiological way. He said that these experiments and others that he also projected tell a clear story. Blood (serum) progesterone levels do not adequately reflect what tissue levels in a woman’s breasts are. On the other hand saliva hormone levels do give an accurate account of what breast tissue levels are like. A woman received 30 mg of topical progesterone application. She then had hourly progesterone levels in the serum and in the saliva done. The serum progesterone levels remained at around 2 ng/ml, while the saliva progesterone levels peaked 3 to 5 hours after the application. It reached 16 ng/ml in saliva, which also represents the breast tissue progesterone level.

Blood progesterone levels are unreliable

As a result, Dr. Zava said that the important lesson to learn from this is not to trust blood progesterone levels. Too many physicians fall into this trap and order too much progesterone cream, which leads to overdosing progesterone. In contrast, with salivary progesterone levels you see the physiological tissue levels, with blood tests you don’t. Dr. Zava said: avoid using venipuncture blood or urine in an attempt to interpret hormone test levels, as you will underestimate bio-potency and overdose the patient.

Historical failure of estrogen replacement therapy (ERT)

A review of breast cancer would not be complete without mentioning the Women’s Health Initiative (WHI). The U.S. National Institutes of Health (NIH) initiated this trial in 1991.

Researchers prematurely terminated Women’s Health initiative

The WHI ended suddenly in July 2002. The authors stated: “The overall health risks exceeded benefits from use of combined estrogen plus progestin for an average 5.2 year follow-up among healthy postmenopausal US women.” The study found a 41% increase in strokes, 29% increase in heart attacks, 26% increase in breast cancer, 22% increase in total cardiovascular disease, a doubling of blood clots. The recommendation made by this study was to discontinue PremPro.

Breast cancer in the Million Women Study from synthetic hormones

Another study that was mentioned was “Breast cancer and hormone-replacement therapy in the Million Women Study”.  In this study postmenopausal women received HRT with synthetic hormones, either estrogen alone or estrogen mixed with a progestin (in British English “progestagen”). After 5 years estrogen alone had a 30% increased risk of developing breast cancer. HRT with an estrogen-progestagen mix had a 100% increased risk of developing breast cancer.

Huge difference between bioidentical hormones and synthetic hormones

Unfortunately in both of these human experiments the researchers used the wrong hormone substances, namely synthetic estrogens and synthetic progestins. They are NOT identical with natural estrogens and progesterone that a woman’s body makes. As long as the hormones used for hormone replacement therapy are chemically identical to the natural hormones, the body will accept them as they fit the natural hormone receptors in the body. It is the misfit of synthetic hormones that blocks the estrogen receptors or the progesterone receptors. You can readily see from the illustrations of this link that there is a fine balance between the workings of these receptors and there is absolutely no room for patented side chains that Big Pharma introduced into synthetic HRT hormones.

Individualizing bioidentical hormone prescriptions based on blood tests

The other problem of both these studies was that every woman was getting the same dose of hormones and that nobody measured their estrogen blood or estrogen saliva hormone levels. In retrospect the regulatory agencies should never have allowed these “hormones” to hit the market.

Breast cancer develops in three stages

Dr. Zava explained that it common knowledge for some time that breast cancer develops by going through 3 stages.

  1. Initiation

First of all, damage to the DNA of one of the cells types in the breast is what starts the process in the development of breast cancer. This can be done by catechol estrogen-3,4-quinones as was shown by these researchers.

Aromatase inhibitors is useful to reduce estrogen in overweight or obese women where aromatase is present in fatty tissue. The reason obese women have more breast cancer is likely from the extra estrogen production from androgens. Aromatase converts these male hormones from the adrenal glands into estrogen.

Iodine/iodide alters gene expression, which reduces breast cancer development, but also slows down cell division in existing breast cancer. The authors suggested to use iodine/iodide supplements as adjuvant therapy in breast cancer treatment.

  1. Promotion

Furthermore, the next step is that something has to promote the DNA mutation into becoming part of a cancer cell. Estrogen quinones are dangerous estrogen metabolites. They can form from catechol estrogens (other metabolites of estrogen) by reactive oxygen species. But selenium, a trace mineral can interrupt the formation of estrogen quinones, which stops the breasts cancer promotion process. A study from the Klang Valley, Malaysia showed that selenium showed a dose-response effect with respect to prevention of breast cancer; the more selenium in the food, the less breast cancer occurred.

  1. Progression (includes invasion and metastases)

Finally, several factors can help the breast cancer cells to progress, grow bigger locally and eventually move into other areas of the body as metastases. Dr. Zava showed several slides where details of metabolic processes were shown and how changes in some of these would lead to progression of breast cancer. Estrogen excess is a common pathway to breast cancer. The key is to balance it with progesterone, supplements, remove anything that causes estrogen overproduction like obesity (via the aromatase pathway).

The fallacy of overdosing or underdosing

When estrogen is overdosed, it becomes aggressive as indicated before; it can initiate DNA mutations that can cause breast cancer. If it is under dosed, the lack of estrogen can cause heart attacks, strokes and osteoporosis. When estrogen is balanced with progesterone a postmenopausal woman feels best and she is protected from the negative effects of estrogen.

Measures that help prevent breast cancer

Supplement only with bioidentical hormones

When supplementing with bioidentical hormones, keep estrogen within physiological limits and don’t overdose. This can be measured through blood tests or saliva hormone tests. Your most important natural opponent of estrogen is progesterone, which is usually missing in menopause. Measure hormones using tests (progesterone only with saliva tests, estrogen either by blood tests or saliva tests). Don’t rely going by symptoms.

Progesterone to estrogen ratio

Keep the progesterone to estrogen ratio (Pg/E2) at an optimal range, which is in the 100- to 500-fold range. Measure the saliva hormone level of both progesterone and estrogen and calculate. Remember that progesterone serum levels are meaningless. The much higher progesterone level protects the postmenopausal woman from estrogen side effects. Here is a statement worth noting: “Until evidence is found to the contrary, bioidentical hormones remain the preferred method of HRT.” This was the conclusion of a study using bioidentical hormones, where the protection from breast cancer and heart attacks and strokes was also noted.

Eat more fiber containing foods and less beef

Increase fiber intake and reduce red meat consumption. This will eliminate conjugated steroid hormones in the stool. It also increases the sex hormone binding globulin in the blood, which limits the bioavailability of estrogens. Fiber absorbs bile toxins and removes them from the body.

Calcium supplement

Calcium-D-glucarate is a supplement that will decrease beta-glucuronidase. The estrogens were conjugated with the purpose to be eliminated, but beta-glucuronidase causes the conjugated estrogens to be reabsorbed.

Reduce breast cancer risk with probiotics

Probiotics likely stimulate the immune system and help reduce the risk of breast cancer.

No pollutants and toxic chemicals

Avoid toxins like petrochemical pollutants and toxic chemicals. Avoid trans fats. If toxic, heavy metals are present (arsenic, cadmium, lead, mercury) remove these. Some naturopaths use EDTA chelation to do this.

Other useful supplements

Supplements: sulforaphane (broccoli), EGCG (green tea), alpha-lipoic acid (antioxidant), cruciferous vegetables, resveratrol, selenium and iodide/iodine, N-acetyl cysteine-glutathione. All these supplements/nutrients will prevent estrogen to go to the “dark side”. The dark side is the formation of toxic 4-OH estrogen that could further be converted into catechol estrogen-3,4-quinones that can damage DNA and cause mutations.

Methylation of catechol estrogens

Increase methylation of catechol estrogens: vitamin B1, B6, B12 and folic acid. Methyl donors also are useful for this purpose: MSM (methylsulfonylmethane), SAMe, and Betaine.

Healthy lifestyle (diet , exercise) helps your immune system

Improve your diet (Mediterranean type), exercise moderately, reduce stress, and replace hormones in physiological doses as discussed under point 1 and 2.

Breast Cancer Risks

Conclusion

Dr. David Zava, PhD gave an interesting talk at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas. Estrogens, when unopposed by enough progesterone, can cause mutations in breast tissue of women and cause breast cancer. He also reviewed two major clinical trials that utilized hormone replacement therapy (HRT). The problems with these were the synthetic estrogen hormones that caused breast cancer and the synthetic progestins that also behaved like estrogens (not like progesterone) and caused even more breast cancer. The lesson from this is that only bioidentical estrogens and progesterone work in hormone replacement for menopause. Also, the hormones balance each other as discussed under measures that help to prevent breast cancer. In addition there was a list of other useful supplements given that can be taken to reduce the danger of breast cancer.

When Food Causes Inflammation

Dr. Hal Blatman gave a talk about when food causes inflammation. He gave his talk on Dec. 9 at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended. The original title was “Food, Pain and Dietary Effects of Inflammation”.

Dr. Blatman is the medical director of Blatman Health and Wellness Center, Cincinnati and Batman Medical Services, Manhattan.

General remarks about nutrition

Dr. Blatman pointed out that mistakes of nutrition are often behind chronic diseases and illnesses. The physician’s task is to explain to patients how they can change their food intake to improve inflammation in the body and to allow the body to heal itself.

Hippocrates said 400 BC “Let food be thy medicine and medicine be thy food”.

In this context Dr. Blatman stated that nutrition could exacerbate symptoms or relieve symptoms and there must be rules for good nutrition. If we do not take care of our nutrition, the gut flora composition changes and causes leaky gut syndrome. But if we consume healthy foods all of this improves.

Mathematical formula for when food causes inflammation

To make it easier to understand the impact of food on our health the speaker offered this formula:

G-B+R=P

G = stands for good, beneficial things you can put into your body.

B = bad, toxic things that affect your body negatively.

R = reserves that your body has since birth (minus the amounts you have used up)

P = pain and problems you are going to experience

It is P (pain and other medical problems) what brings the patient to see the doctor. G and B is what the patient can change. When done right, the P value in the formula reduces and the pain or medical problems go away.

Nutritional rules

Dr. Blatman said there are three rules about nutrition.

Rule #1 is to not eat fake or toxic foods

He listed NutraSweet, Splenda, Saccharin, margarine and olestra.

Aspartame

Aspartame experiments on rats showed that it can cause cancer: Dr. Blatman said that aspartame causes multiple myeloma and Hodgkin’s lymphoma in man. Aspartame worsens depression, 10% is metabolized in the liver into methanol, a nerve poison.

Splenda

Splenda (sucralose) originates from sugar. However, several chlorine atoms were inserted into the sugar molecule. It reduces beneficial microflora in the gut. It also interacts with liver enzymes, which interfere with the bioavailability of oral drugs.

Saccharin

Saccharin alters gut bacteria and increases glucose tolerance.

Hydrogenated fat and margarine

Insects don’t eat margarine, mold will not grow on it, and it will not support life. Merchants like it because food does not turn stale on shelves. Hydrogenated fats like margarine are like poisons. They raise the bad LDL cholesterol levels and reduce beneficial HDL cholesterol levels. The prostaglandin balance changes so that inflammation occurs. There is increased evidence of diabetes and the cell membrane composition changes. Proinflammatory cytokines can cause pain in the dorsal root ganglions. It follows from all of this that it is best to cut out all hydrogenated fat and margarines.

Partially hydrogenated vegetable oil

The cell membrane consists of two lipid layers at a specific ratio of omega-6 essential fatty acids and omega-3 essential fatty acids. It also contains triglycerides, phospholipids and protein. Cell membrane absorb nutrients to move into the cell and eliminate waste out of it. The cell membrane needs to remain flexible and within neurons needs to transmit electrical information. The membrane composition is critical for the cell membranes to perform optimally. It is here that the physician has to explain this to the patient. All the fats we eat are the raw material, which will make up our cell membranes. So what fat we eat that day travels into the cell wall that becomes part of it that day. The same process occurs with cell wall repair. If we eat hydrogenated fat that day, it travels into the cell wall.  A membrane with hydrogenated fat will:

  • Not transmit nutrients inside the cell
  • Will not transmit waste out
  • Causes the membrane to lose flexibility
  • In a nerve cell there will be abnormal neuron transmission

If we eat hydrogenated fat, we become like a “genuine GM truck fixed with inferior parts”, so Dr. Blatman. The interesting observation is that it takes 4 months after eliminating hydrogenated oil from the diet to get it out from red blood cells. Be aware that French fries increase pain for 4 months, so why eat them?

Olestra

Olestra, an artificial fat: This fat, Olestra has been developed as an artificial fat and is used in chips. It can cause diarrhea, abdominal cramps and weight gain with long-term use. Olestra belongs into the group of fake/toxic foods. Don’t eat Pringles or chips that are made with this.

Healthy oils

There are two types of essential fatty acids, omega-6 fatty acids and omega-3 fatty acids. Many processed foods contain only omega-6 fatty acids, because this is the cheapest way to produce them (they are based on vegetable oils). Instead you want to eat healthy fats like omega-3 fatty acids contained in nuts and fish. You can also add molecularly distilled, high potency omega-3 fatty acids (purified fish oil) as a supplement to help restore the balance between omega-6 and omega-3 in your food intake. Avoid omega-6 fatty acids from corn oil, safflower oil, grape seed oil, soybean oil, cottonseed oil, canola oil and peanut oil.

Metabolism of omega-6 fatty acids versus omega-3 fatty acids

Compare the metabolism of omega-6 fatty acids with that of omega-3 fatty acids.

The linoleic acid of omega-6 fatty acids gets metabolized into arachidonic acid, which causes pro-inflammatory mediators, PGE2 and LTB4. On the other hand with omega-3 fatty acids alpha-linolenic acid (ALA) is metabolized into EPA, DHA and the anti-inflammatory mediators PGE3 and LTB5.

It is easily understandable why a surplus of omega-6 fatty acids from processed foods will disbalance the omega-6 to omega-3 ratio. This ratio should be 1:1 to 3:1, but many Americans’ omega-6 to omega-3 ratio is 6:1 to 18:1. Omega-6-fatty acids cause arthritis, heart disease and strokes. Be particularly careful in avoiding soybean oil, which is the most popular oil in the last few decades to foul up the omega-6 to omega-3 ratio through processed foods.

Balance of omega-3 and omega-6 fatty acids

When it comes to balancing omega-3 and omega-6 fatty acids in your diet, be aware that nutritional balancing can help you restore the ideal omega-6 to omega-3 ratio of 1:1 to 3:1. An easy way is to cut out processed foods as much as possible. Supplement with molecularly distilled fish oil capsules to add more omega-3 fatty acids into your food intake. Dr. Blatman gave the example of rheumatoid arthritis patients that were put on omega-3 supplements. After 24 weeks their joint swelling and tenderness went down.

Rebalancing the omega-6 to omega-3 ratio was able to treat depression as this research showed. This makes you wonder how much depression may be caused by overconsumption of processed food.

Suggested doses of omega-3 fatty acid supplementation

Dr. Blatman suggested the following doses of omega-3 supplementation for various purposes:

  • 1 gram/day as supplementation for healthy adults with a good diet
  • 1-3 grams/day for people with cardiovascular disease
  • 5-10 grams/day for patients with an autoimmune disease, with chronic pain or with neuropsychiatric conditions

He mentioned that these doses are empirical, but in his opinion definitely help. Due to quality differences he suggested that you buy fish oil capsules in a health food store where the quality is best. Stay away from discount stores (the quality is the worst) and drug stores.

Other healthy oils are olive oil and coconut oil. They are also useful for cooking.

Rule #2 is not to eat inflammatory foods

Our body functions like a luxury car; it needs pure food to function. Anything less leads to inflammation, particularly when you eat sugar and processed foods.

Inflammatory foods are sugar, white flour, fruit juice and white/red potatoes. A medium potato=1/2 cup of sugar! Other problematic foods are wheat grain contained in breads, pasta, cereal and thickeners in soups and sauces.

What is the problem with these foods? They break down the zonulin proteins that are a bridge between the lining cells of the gut.

This leads to an increase of intestinal permeability, and leaky gut syndrome can develop. Inflammatory cytokines from visceral fat add to the gut inflammation, and cardiovascular disease and high blood pressure can develop.

Fried potatoes, in particular the consumption of French fries, have been identified as the cause of inflammatory bowel disorder (IBD). Countries with the highest consumption of French fries have the highest incidence of IBD.

A Mediterranean diet and the DASH diet are anti-inflammatory diets.

Rule #3 is to not disturb the bowel flora

A healthy bowel flora is symbiotic with the body. You achieve this by eating green leafy vegetables. A toxic flora from dysbiotic microbes comes from eating white flour, white sugar and red meat. Red meat leaves residues on which dysbiotic bacteria thrive.

Symbiotic gut bacteria produce vitamin K, cobalamin, pyridoxine, biotin, riboflavin, pantothenic acid and short fatty acids. They also degrade metabolic toxins, prevent pathogens from colonization and they stimulate the immune system to mature.

Dysbiosis occurs when the wrong diet consisting of sodas, white flour, sugar and red meat is over consumed. There are toxins that are produced by the dysbiotic microbes. These injure the bowel wall and make the immune system work harder. Immune system dysfunction, fatigue and fibromyalgia can follow.

Dr. Blatman stated that gut dysbiosis that causes leaky gut syndrome could also cause ulcer disease, diabetes, heart disease, fibromyalgia, chronic fatigue syndrome, chronic pain and even cancer.

Conclusion

This was a whirlwind tour through a talk given by Dr. Blatman during the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas. What food we eat determines what gut bacteria we harbor, symbiotic ones or toxic ones. This in turn determines which way our health develops. But the content of what we eat is also important. If we consume processed foods we end up consuming way too many omega-6 fatty acids, which cause inflammation, arthritis and heart disease. This is happening in front of our eyes, if we start seeing things the way they are. I was aware of this since the mid 1990’s. In a lecture I attended at a continuing education conference a cardiologist pointed out that inflammation was the determining factor of whether or not our patients would get a heart attack.

Cholesterol concept being replaced by inflammation concept

The lecturer mentioned then that the older cholesterol concept would be replaced by the newer inflammation concept. He was right, but it goes even further! There is the important omega-6 to omega-3 ratio, and fish oil supplementation helps. At the same time it is necessary cutting out processed foods. But there is the newer insight that our bowel flora and red meat consumption can culture toxic bacteria in our own gut. It is in our power to start eating more vegetables and cut out sugar and starchy food. It is time to see chips and French fries not as a “convenience” but a hazard to your health. Food does not have to cause inflammation; right food choices will help us to stay well and live longer.

How Stress Affects Our Hormone System

Dr. Andrew Heyman gave a detailed talk recently about how stress affects our hormone system. He presented his talk at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended. It was entitled “Understanding the Stress, Thyroid, Hormone Connections & Prioritizing Systems”.

Dr. Heyman stressed in particular that there is a triad of hormonal connections that is important to remember: the thyroid hormones, the stress hormones (adrenal glands) and the pancreas (insulin production). It seems like we need a balance of these hormones for optimal energy production and circulation. Under stress our sugar metabolism can markedly derail, we develop obesity and fatigue. But when balanced we experience vitality and wellbeing.

Metabolic activation pathways

Dr. Heyman projected a slide that showed the metabolic activation pathways. Likewise, he stated that a number of different factors could influence the hormone system:

  • Diet: trans fats, sugar, too many carbs, food allergies.
  • Drugs: drug-induced nutrient depletion (over-the-counter drugs, prescription drugs).
  • Physical exercise: frequency and type matters.
  • Environmental exposure: chemicals, pesticides, herbicides, heavy metals, plastics, molds, and pollens.
  • Stress: physical stress, psychogenic stress.
  • Genetics: methylene-tetra-hydro-folate reductase enzyme deficiency (MTHFR mutation), APOE genes, lack of vitamin D
  • Disease: past or present conditions, active disease or syndromes.

Target areas within your system

The target areas in your system are the

  • Pancreas, where blood sugar can rise because of insulin resistance. In particular, too much insulin production causes inflammation, hormone disbalances, kidney damage, and hardening of the arteries through plaque formation.
  • Thyroid gland, which depends on TSH (thyroid stimulating hormone) for activation. Autoantibodies can also affect it negatively.
  • Brain: decrease in serotonin resulting in anxiety, depression and food cravings; decreased melatonin causing sleep disturbances; increased ghrelin and decreased leptin secretion leading to overeating and obesity.
  • Liver/kidneys: both of these organs are important for detoxification; the liver produces thyroid binding globulin, which when increased can lower the free thyroid hormones.
  • Immune system (gut, lymph glands): the Peyer’s patches in the gut mucosa produce a large portion of the immune cells; lymph glands, the bone marrow and the spleen supply the rest. A leaky gut syndrome can affect the whole body, in addition causing inflammation and autoimmune reactions.
  • Hypothalamus/pituitary/adrenal glands: this is the main axis of the stress reaction. A brain under stress activates the hypothalamus. It sends a cascade of activating hormones via the pituitary gland and likewise activates the adrenal glands. Finally this leads to cortisol overproduction, and release of epinephrine and norepinephrine from the center of the adrenal glands. High blood pressure, anxiety, heart palpitations, arrhythmias and more can finally develop from this.

Hypothalamus/pituitary/adrenal glands activation and clinical effects

The main hormone axis of the stress reaction goes first from the hypothalamus, secondly via the pituitary gland and thirdly to the outside surface of the adrenal glands, which produces cortisol. The term for this is the HPA axis. Stressed people, therefore, make too much cortisol, which weakens immune functions, reduces human growth hormone production, increases belly fat, increases blood pressure and reduces insulin action. In addition, stress also reduces estrogen production in women and testosterone production in men.

Accordingly, the final clinical presentation is osteopenia, then osteoporosis with spontaneous fractures of bones. In addition there is also cardiovascular disease leading to heart attacks and strokes, and cognitive decline with memory loss. There are complications with infections. Also the metabolic syndrome can lead to obesity and type 2-diabetes.

Stress and the hippocampus

In the center of our brain there is a memory-processing unit, the hippocampus that converts short-term memory into long-term memory. Repeated stress interferes with normal hippocampus function. Indeed, high cortisol levels interfere with the proper functioning of the hippocampus causing memory problems.

Hippocampus atrophy can come from chronically high cortisol levels due to chronic stress. In addition this can lead to Alzheimer’s disease.

Effects of chronic stress

Chronic stress leads to cardiovascular disease, to diabetes, chronic inflammation, Alzheimer’s disease, thyroid disorders, cancer, neurological disorders and autoimmune diseases. Researchers showed that inflammation releases tumor necrosis factor-alpha (TNF-alpha), which is a key player of chronic inflammation. This, however leads to the release of other inflammatory kinins like IL6 and others. The resulting chronic inflammation can cause Crohn’s disease, rheumatoid arthritis, insulin resistance, dementia, metabolic syndrome, obesity and atherosclerosis with associated markers (decreased HDL, increased LDL, CRP and triglycerides).

Hormone imbalance causes disease

  1. Excess cortisol production from stress leads to Th2 type inflammatory kinins; usually associated with this is a reduction of DHEA (a male hormone in the adrenal glands), which leads to reduced Th1 type kinins. Overall, the end result is chronic inflammation. When chronic stress has tired out the adrenal glands, a four-point salivary cortisol level test shows a flat curve. This indicates adrenal gland fatigue or, if worse, even adrenal gland insufficiency. Most noteworthy, patients with leukemia, breast cancer, uterine cancer, prostate cancer, pituitary gland cancer and lung cancer show such a pattern.
  2. The disregulation of the HPA axis is particularly evident in patients with metabolic syndrome. People who have this syndrome have a high morning serum cortisol level. As a matter of fact, high cortisol increases the risk to develop metabolic syndrome.
  3. Metabolic connections: high cortisol leads to a partial blockage of thyroid hormones, which in turn leads to hypothyroidism. Hypothyroidism will affect glucose tolerance, and if not treated leads to type 2 diabetes.

In a large study involving 46,578 members of Kaiser Permanente Northwest it was determined that for every 1 point above a fasting glucose level of 84 mg/dL there was an additional 6% risk to develop type 2 diabetes over the next 10 years.

Pathological hormone disturbances

Dr. Heyman mentioned the following hormone patterns that he discussed in detail, increased cortisol levels, increased insulin levels and decreased thyroid levels.

Elevated cortisol

Prolonged elevation of cortisol leads to atrophy of the hippocampus with brain atrophy and Alzheimer’s or dementia. The immune system gets altered, there is lower DHEA hormone leading to weaker muscles and weakened immunity. There is insulin resistance (decreased insulin sensitivity), decreased serotonin and increased depression. Carbohydrate cravings lead to weight gain (central obesity). Changes in the thyroid metabolism leads to hypothyroidism.

Increased insulin level

People who develop high insulin levels are usually sugar or carbohydrate addicts. As they gain weight they change their metabolism into the metabolic syndrome. The extra insulin that is floating around triggers the insulin receptors to become less sensitive (also called “resistant”). The people love to eat. They snack frequently on protein bars and candy bars. As they gain weight, consequently their energy goes down and as a result they often develop painful joints. This prevents them from being physically active. They notice episodes of foggy thinking. Women complain of frequent yeast infections.

The body tries to compensate by slightly decreasing thyroid hormones and slightly increasing cortisol levels.

Decreased thyroid levels

There is increased lactic acid production and decreased insulin sensitivity. Oxidative stress is increased. The patient is depressed and cognition and memory are reduced. Also, the gut has slower motility. The mitochondria, the energy packages in each cell are reduced and functioning less productively. Cardiac function is reduced.

The body tries to compensate for the primary thyroid weakness by slightly elevating insulin and cortisol.

Treatment of stressed hormone system

Before the doctor can treat a disbalanced hormone system, blood tests have to be done that show what kind of hormone constellation is present. Dr. Heyman suggested the following support with supplements.

Treatment of thyroid disorders

Thyroid supplementation may involve any of these: Selenomethionine, iodine, chromium, thyroid glandular, tyrosine, ferritin, Ashwagandha, coleus forskohlii, 7-keto DHEA, ferritin and iron. Other possible supplements that were mentioned by Dr. Heyman were Rhodiola, schisandra, ginseng, Rg3, eurycoma longifolia, neuromedulla glandular, DHEA, tryptophan/5 HTP, licorice, Cordyceps.

This, however, is not all. Missing thyroid hormones need replacement with a balanced T3/T4 medication like Armour thyroid.

Adrenal support

The following supplements are used to support adrenals: Adrenal glandular, vitamin C, adrenal cortex extract, Holy Basil, Pharma GABA, Magnolia/Phellodendron, L-theanine, sterols & sterolins.

Pancreatic support

These supplements support the insulin production in the pancreas:

Chromium, vitamin D, magnesium, alpha-lipoic acid, fish oil, micro PQQ, bitter melon, cinnamon, arginine, vanadium, benfotiamine (synthetic derivative of B1 vitamin) and Bergamot.

Dr. Heyman completed his talk by giving a few patient examples, explaining what blood tests showed, what the hormone disbalance was, and which treatment options were helpful.

How Stress Affects Our Hormone System

How Stress Affects Our Hormone System

Conclusion

Dr. Andrew Heyman gave a talk at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended. He talked about how stress in due time affects our hormone system. Symptoms from stress can stem from different causes including hormone disbalances. Given these points, conventional medicine would simply treat the symptoms. However, this will not be successful with stress-induced hormone disbalances, namely, because it does not treat the causes. Obviously only causal treatment of the hormone disbalance will restore the person’s wellbeing and the symptoms will disappear at the same time. In short, anti-aging medicine and integrative medicine are attempting to follow this approach.

Gut Bacteria Can Protect Your Brain

The neurologist, Dr. David Perlmutter gave a keynote address where he pointed out that gut bacteria can protect your brain. The topic of his actual talk was “Rewrite your brain’s destiny” and the venue was the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas. Many of the talks centered around the gut microbiome. Specifically, in this talk Dr. Perlmutter stressed the fact that the right mix of gut bacteria will protect your brain, while the wrong mix can make you sick. There were many slides, but too much information to mention all of details of the talk here. With this in mind, I will summarize the broad outline of Dr. Perlmutter’s presentation and certainly emphasize the practical implications this has for everyday life to prevent degenerative brain diseases.

A few facts

Did you know that the brain uses 25% of the body’s energy, but has only a 3% of the body’s weight?

There are trillions of gut bacteria

The gut flora has trillions of gut bacteria with its own DNA material. 99% of the DNA material in our body comes from the gut bacteria and the bacteria on our skin surface; only 1% of the entire DNA in the body is your own DNA. We are eating for 100 trillion bacteria, but it is important to remember that if they are good bacteria they provide us with important vitamins and they produce molecules that stimulate our immune system.

We need healthy gut bacteria

This means we better have bacteria in our guts that are friendly, not the bad bacteria that can cause us problems. An Italian study determined the gut flora of children in central Africa (Burkina Faso) and compared the gut flora to children from developed countries in Europe. There was a significant difference with the African children having a healthy microbiome in the gut and the children from developed Europe having unhealthy gut bacteria. This is important new information. Many other research papers have established that leaky gut syndrome and autoimmune diseases are linked to dysbiosis, which is the name for the unhealthy microbiome in the gut.

Chronic inflammation

Dr. Perlmutter showed several slides where literature was cited showing that chronic inflammation in the civilized world is increasing. He also showed that dysbiosis (unhealthy gut bacteria taking over) is also increasing. On several slides Dr. Perlmutter showed that in civilized countries like Iceland, Denmark, Germany, the US, Japan and others the bacterial diversity of the gut bacteria in people was vastly reduced compared to the diversity of gut bacteria of people in Kenya, Ethiopia, Nigeria or rural India.

Diminished gut bacterial diversity causes more Alzheimer’s disease

The same countries that have diminished gut bacterial diversity (dysbiosis) also have the highest prevalence of Alzheimer’s disease. On the other hand the same countries with diverse gut bacteria have a low incidence of Alzheimer’s disease. When infestation with parasites was examined there was also a parallel between increased parasitic stress and low Alzheimer’s disease rates, again in countries like Kenya, Ethiopia, Nigeria or rural India. The same countries where gut dysbiosis was present the parasitic infestation was low.

Further research has established that gut dysbiosis leads to an inflammatory condition of the gut where lipopolysaccharides (LPS) from gut bacteria are absorbed causing inflammatory reactions within the body.

Leaky gut syndrome causes neurological diseases

At the same time this leaky gut syndrome can cause obesity and leakage in the gut/brain barrier as indicated in this link. The result is neuroinflammation, cognitive impairment and vulnerability to develop Alzheimer’s disease. Our most dreaded brain diseases come from inflammation: Alzheimer’s, Parkinson’s disease, autism, multiple sclerosis etc. These are degenerative brain disorders due to chronic inflammation. If you eat a lot of red meat, sausages and processed foods your gut microbiome will undergo negative changes. If you eat healthy food with lots of vegetables, fruit and you cut out sugar and too many starches, you have a healthy microbiome, which develops a robust immune system. We have to rethink the gut/brain connection and learn how to prevent these chronic illnesses.

Obesity and gut dysbiosis

The link above showed that obesity has a connection to inflammation. It was also shown with MRI scans that the part in the brain, called hippocampus was shrivelled up (atrophied). This is a typical sign of dementia and Alzheimer’s disease. The investigators also confirmed with mental health functional tests that these patients had cognitive decline.

Another study also noticed that in a group of obese patients the hippocampus part of the brain was shriveled up the more obese people were. Obesity and dysbiosis of the gut flora are part of the same problem.

Practical application: the DASH diet and the Mediterranean diet are both healthy, balanced diets, strikingly different from the Standard American diet. In a study the hypothesis was tested whether the DASH diet and the Mediterranean diet would postpone dementia in a group of elderly patients. The answer was: yes, the hypothesis is true.

What does gut dysbiosis do?

It was shown in mice that chronic inflammation of the gut through ingestion of an irritant (dextran sodium sulfate) led to reduced new nerve growth in the hippocampus compared to control animals. It only took 29 days to show a marked difference between experimental and control animals in terms of reduced growth in the nerve cells of the hippocampus, the center of cognitive control.

The gut wall released inflammatory kinins, which were the negative mediators affecting the brain.

Antibiotic residue and Roundup in food causes gut dysbiosis

Antibiotic treatments and antibiotic residues in milk, milk products, meat, but also in all GMO foods are the irritants of the gut wall in humans. The antibiotics change the gut flora and lead to dysbiosis, which then causes gut wall inflammation and the cascade of events described above. The new finding is that GMO food contains RoundUp (they are “Roundup ready” crops). The herbicide Roundup was originally patented as an antibiotic and still leads to significant dysbiosis. Dr. Perlmutter urged the audience to buy organic food as the only method to reduce our exposure to Roundup. Roundup contributes to causing celiac disease and gluten intolerance in addition to exposure to the modern wheat (Clearfield wheat). The FDA is starting to do testing on foods for Roundup (glyphosate).

Roundup linked to cancer

If things are sounding bad for Roundup, it only gets worse: Roundup has now been linked to causing cancer. In medicine it usually takes some time before the effect becomes obvious is. The agriculture industry has embraced the use of Roundup; I suspect that denial will be the first line of defense. My first line of defense in turn is to stick to organic food.

To sum up: Roundup and the Standard American diet lead to dysbiosis in the gut, which causes leaky gut syndrome. This causes inflammation with the release of cytokines and LPS from the gut wall to the blood. These substances cross the blood/brain barrier and lead to inflammation in the brain. This affects the hippocampus with the classical sign of shrinkage.

Chronic inflammation and neurological disease

But Parkinson’s disease, multiple sclerosis, autism in children and Alzheimer’s disease in older people are all caused by chronic inflammation. There are three more brain-related diseases that are related to gut inflammation: stroke, depression and attention deficit hyperactivity disorder (ADHD). Dr. Perlmutter spent some time explaining that antibiotic overuse even leads to an increase of breast cancer as a Danish study has shown. Antibiotic use showed a linear increase of breast cancer as a result of increased antibiotic amounts used. The highest group had a twofold risk compared to a control group with no antibiotic use. Dr. Perlmutter interpreted this to indicate that chronic gut inflammation can even cause a disease like breast cancer.

What can we do to diversify our gut bacteria?

  1. Exercise: A recent study has shown that regular exercise is associated with a diversified gut flora. The reason seems to be the production of butyrate with exercise, which leads to a diversified gut flora. LPS levels (lipopolysaccharides from gut bacteria) are lower in people with a higher fitness score.
  2. Eat a DASH diet or the Mediterranean diet as indicated above.
  3. Avoid GMO foods because of the presence of Roundup, which functions like an antibiotic and leads to gut bacteria dysbiosis.
  4. Remember “Antibiotics are weapons of mass microbial destruction”. If you need to take them be careful that you rebuild your gut flora with probiotics. Use of antibiotics increases the risk of type-2 diabetes by 1.53-fold. It also causes a quadrupling of Alzheimer’s disease.
  5. A woman should consider natural childbirth whenever possible, as with a vaginal birth the child gets into contact with gut bacteria. Vaginally delivered children remain healthier than children delivered by Cesarean section for several years.
  6. Acid-suppressing medications and NSAIDs (anti-inflammatory medication for arthritis) can also lead to dysbiosis. Proton pump inhibitors increase the risk of Alzheimer’s disease by 44%.
  7. Prebiotic fiber can prevent Alzheimer’s. Probiotics do the same.
  8. Avoid sugar: even the Oompa Loompa knew that “If you eat sugar, you get fat”. Obesity and gut dysbiosis cause a higher risk of degenerative brain diseases.
  9. Take magnesium supplements (250 mg twice per day) and DHA from fish oil capsules. It stabilizes your brain metabolism.
  10. In severe, persistent cases of gut dysbiosis a fecal transplant can be considered by your gastroenterologist. This procedure takes place in more than 500 hospitals in the US.
Gut Bacteria Can Protect Your Brain

Gut Bacteria Can Protect Your Brain

Conclusion

The diversity of gut bacteria is immensely important. As discussed, in rural areas of the world there is gut bacteria diversity. In civilized parts of the world dysbiosis of the gut flora frequently occurs. This can lead to gut inflammation and the inflammation eventually becomes internal and can even reach the brain. These are the points to remember: exercise; avoid GMO foods, use prebiotics and probiotics. Avoid antibiotics; also avoid meat from animals that were fed antibiotics for faster growth. Don’t eat processed foods and avoid sugar. A healthy gut creates a healthy body, and this includes a healthy brain as well.

Magnesium Is Essential To Life

Magnesium is an important co-factor in many biochemical reactions, so magnesium is essential to life.

Many diverse diseases and cancers can develop from magnesium deficiency. The key is to supplement with magnesium regularly to get more than the government recommended daily allowance (RDA). The RDA for magnesium is 420 mg a day for males and 320 mg a day for females.

In the following I will review the diseases that occur without enough magnesium on board.

A lack of magnesium can cause heart disease

In this 2014 study 7216 men and women aged 55-80 with at high risk for heart attacks were followed for 4.8 years. The risk of death from a heart attack was found to be 34% lower in the high tertile magnesium group when compared to the lower magnesium tertile group.

The protective mechanism of magnesium was found to be as follows. Magnesium counteracts calcium and stabilizes heart rhythms. Magnesium helps to maintain regular heart beats and prevents irregular heart beats (arrhythmias). It also prevents the accumulation of calcium in the coronary artery walls. This in turn is known to lower the risk of heart attacks and strokes.

Another study, which was part of the Framingham Heart Study, examined calcification of the heart vessels and the aorta as a function of magnesium intake.

There were 2,695 participants in this study. For each increase of 50 mg of magnesium per day there was a 22% decrease in calcification of the coronary arteries. For the same increase of magnesium the calcification of the body’s main artery, the aorta, fell by 12%. Those with the highest magnesium intake were 58% less likely to have calcifications in their coronary arteries. At the same time they were 34% less likely to have calcifications of the aorta.

In a Korean study a group with low magnesium levels was at a 2.1-fold higher risk of developing coronary artery calcifications compared to a group with normal magnesium levels.

Low magnesium increases your stroke risk

In a 2015 study 4443 subjects, men and women aged 40-75 were followed along.

928 stroke cases developed. The researchers compared the group with the highest 30% of magnesium intake with the lowest 10% of magnesium intake. They had significantly lower blood pressure (7 mm mercury) and lower total cholesterol levels. They also had 41% less strokes than those with low magnesium intake.

In a 2015 study that lasted 24 years the authors investigated 43,000 men.

Those with the highest magnesium supplement had a 26% lower stroke risk. Those with the lowest magnesium intake served as a control.

Among women low magnesium levels were shown to cause 34% more ischemic strokes than in controls.

This study included 32,826 participants in the Nurses’ Health Study. Examiners followed them for 11 years.

It is clear from all these studies that supplementation with magnesium can prevent strokes.

Magnesium protects kidney function

This study examined 13,000 adults for 20 years to see how kidney function was dependent on magnesium levels. Those with the lowest magnesium levels had a 58% higher risk of developing chronic kidney disease. It makes sense when you consider that magnesium is necessary to keep arteries healthy, blood pressure low, and blood sugars stable. When diabetics do not control their blood sugars optimally their kidneys develop kidney disease. The term for this is diabetic nephropathy. In the presence of magnesium supplementation and a low sugar diet people are less likely to develop diabetes or kidney disease.

Magnesium helps blood sugar control

A metaanalysis showed that magnesium supplementation was able to improve blood sugar control. This occurred in both diabetics and borderline non-diabetics within 4 months of supplementing with magnesium.

An important factor in helping control blood sugar is magnesium. Here is an article as an example.

Magnesium good for bones and teeth

Magnesium is important for calcium metabolism and this is helping your bones and teeth to stay strong. The bones store half of the body’s magnesium. Another location for magnesium are in our teeth.

Low levels of magnesium lead to osteoporosis, because one of the two structural components of bone (calcium and magnesium) is missing. In addition low magnesium causes inflammatory cytokines to increase. These break down bones. The Women’s Health Initiative showed that when daily magnesium intake exceeded 422.5 mg their hip and whole-body bone mineral density was significantly greater than in those who consumed less than 206.6 mg daily.

With regard to healthy teeth magnesium is important as it prevents periodontal disease.

This study found that there was less tooth loss and there were healthier periodontal tissues in 4290 subjects between 20 and 80.

Those who took magnesium supplements had healthier teeth.

Migraine sufferers improve with magnesium

A double blind randomized study showed that magnesium supplementation can reduce migraines. The researchers in this trial used 600 mg of magnesium supplementation for 4 weeks.

This reduced migraines by 41.6% in the magnesium group compared to the non-supplemented control group.

Another study showed that both intravenous and oral magnesium are effective in reducing migraine headaches.

Intravenous magnesium showed effects on improving migraines within 15 – 45 minutes. The authors concluded that one could supplement other migraine treatments with both oral and intravenous magnesium.

Too little magnesium can cause cancer

It may surprise you to hear that magnesium can even prevent some cancers. Two cancers have been studied in detail. I will limit my discussion to these two.

Pancreatic cancer

One study found that pancreatic cancer was reduced. Researchers recruited 142,203 men and 334,999 women between 1992 and 2000 and included them in the study. After 11.3 years on average 396 men and 469 women came down with pancreatic cancer. On the male side they found that when the body mass index (BMI) was greater than 25.0 there was a 21% reduction of pancreatic cancer for every 100 mg of added magnesium per day. There were a lot of smokers on the female side, which interfered with the study as confounding factors undermined statistical validity.

In another study, the US male Health Professionals Follow-up Study was examined after 20 years of follow-up. Those with a BMI of above 25.0 on magnesium supplementation had a reduced risk of pancreatic cancer. The pancreatic cancer rate in the higher magnesium group was 33% lower than in the lower magnesium group. The higher group consumed 423 mg of magnesium daily, the lower group 281 mg per day. It is significant that in both studies it was the heavier patients who came down with pancreatic cancer. It is common knowledge that obesity is a pancreatic risk factor.

Colorectal cancer

A study done on Japanese men showed that magnesium could protect them significantly from colon cancer.

Men who consumed the highest amount of magnesium developed 52% less colon cancer over 7.9 years. Researchers compared them to the group with the lowest 20% intake of magnesium. The women in this study did not reach statistical significance.

A study from the Netherlands examined colon cancer in patients. They found that only in patients with a BMI of greater than 25.0 magnesium did have protective effects. For every 100 mg of magnesium per day increase there was a 19% reduction of colon polyps. And there was also a 12% reduction of colorectal cancer for every 100 mg increase of magnesium per day.

Magnesium plays an important role in genome stability, DNA maintenance and repair. It also prevents chronic inflammation and reduces insulin resistance, all factors contributing to cancer reduction.

Live longer with magnesium

Consider that magnesium is the fourth most common mineral in the body. Add to this that magnesium is a co-factor of more than 300 enzymes in the body. Magnesium is an important co-factor in the conversion of chemical energy from food that we ingest. Magnesium is regulating blood sugar, blood vessel health and our brain electrical activity. 50% of our stored magnesium is located in our bones, which helps the strength and integrity of them.

Because of the distribution of the enzymes to which magnesium is a co-factor, virtually every cell in the body depends on our regular intake of magnesium.

Magnesium deficiency develops in older age

Since the 1950’s soils have lost magnesium where farmers grow vegetables and raise fruit trees. We simply do not get enough magnesium from food.

But chelated magnesium is freely available in health food stores. Take 250 mg twice per day, and you will have enough.

Because our metabolism slows down, there is a critical age where magnesium deficiency becomes more obvious than when we are younger. By the age of 70 there are 80% of men and 70% of women who do not get the minimum of magnesium-required amount they should get (350 mg for men and 265 mg for women).

Proton pump inhibitors lowering magnesium levels

At this age many people are on multiple drugs. For many proton pump inhibitors (PPI) are used to suppress acid production in the stomach. PPI’s have been associated with low magnesium blood levels. This link explains that when a patient takes PPI’s the total time of taking the medication should not exceed 1 year.

Low magnesium levels accelerate the aging process on a cellular level. Low magnesium levels increase senescent cells that can no longer multiply. Some of them could cause the development of cancer. These senescent cells also can no longer contribute to the immune system. This causes more infections with an adverse outcome.

Remember to take chelated magnesium capsules or tablets 250 mg twice per day and you will be protected from low magnesium levels in your body.

Here is why we live longer with magnesium supplementation

Our blood vessels will not calcify as early; they keep elastic for longer, preventing high blood pressure. Our kidneys will function longer with magnesium, preventing end-stage kidney disease. We need our kidneys to detoxify our system! More than 300 enzymatic reactions all over our body help that we have more energy and also help to prevent cancer. When there are fewer strokes and less heart attacks this helps reduce mortality. Magnesium supplementation helps to lessen the risk for Alzheimer’s disease and also reduces insulin resistance. Researchers have shown that this prevents Alzheimer’s disease.

The bottom line is we live longer and healthier; that is the meaning of longevity.

Magnesium Is Essential To Life

Magnesium Is Essential To Life

Conclusion

Magnesium is a key essential mineral. It balances calcium in the body and participates in many enzymatic reactions in the body as a cofactor. As long as we have enough of this mineral we won’t notice anything. It is with magnesium deficiency that things go haywire. Heart disease or a stroke could affect you . You could get kidney disease. And you could even get pancreatic cancer or colorectal cancer. If this is not enough, magnesium deficiency can cause diabetes, osteoporosis and bad teeth. You may suddenly die with no obvious cause. But, if balance your your magnesium blood level by taking regular supplements, you will carry on living and eliminate a lot of health problems.

Health Risks Of Night Shifts

One of the news stories in 2016 was about health risks of night shifts. The Bureau of Labor Statistics reported in 2000 that 15 million workers (16.8 % of the working population) were doing alternative shifts (night shift work mixed with daytime shifts). In 2016 they reported 14.8% were working alternate shifts. Among blacks, Asians and Latino Americans the percentage of working alternative shifts was higher, namely 20.8%, 15.7% and 16%, respectively.

Shift work is more common in certain industries, such as protective services like the police force, food services, health services and transportation.

Evidence of health risks of night shifts

1.There are several publications that showed evidence of health risks of night shift workers. Here is a random selection to illustrate the health risks of night shifts.A study from 2015 examined the sleep patterns of 315 shift nurses and health care workers in Iranian teaching hospitals. They found that 83.2% suffered from poor sleep and half of them had moderate to excessive sleepiness when they were awake.

2.This South Korean study examined 244 male workers, aged 20 to 39 in a manufacturing plant. Researchers compared blood tests from daytime workers to blood tests from night shift workers. They also obtained inflammatory markers like the C-reactive protein and leukocyte counts. Night shift workers had significantly higher values. The investigators concluded that shift workers have increased inflammatory markers. This is a sign of a higher risk of developing cardiovascular disease in the future.

Higher mortality and higher cancer risk in nighttime workers

3. A Swedish study found that white-collar shift workers had a 2.6-fold higher mortality over a control group of daytime white-collar workers.

4. Another study compared night workers in the age group of 45 to 54 with daytime workers and found a 1.47-fold higher mortality rate in the night shift workers.

5.In a study from China 25,377 participants were included in a study that investigated cancer risk in males with more than 20 years of night shift work. They had a 2.03-fold increased risk to develop cancer compared to males working day shifts. Women with night shift work in this study showed no effect with regard to cancer development.

BMI and estrogen levels higher in women nighttime workers

6.A Polish study examined hormones and the body mass index (BMI) among 263 women who worked night shifts and 269 women who worked day shifts. When night shift workers had worked more than 15 years at nights, their estrogen levels, particularly in postmenopausal women were elevated compared to the daytime workers who served as controls. The BMI was also increased in the nighttime workers.

Risk for chronic lymphocytic leukemia higher in nighttime workers

7.Chronic lymphocytic leukemia (CLL): a study in Spain showed that working for more than 20 years in rotating night shifts was associated with a 1.77-fold higher risk of developing CLL. The authors noted that melatonin levels in that group were much lower than in controls that worked only day shifts. Working in straight night shifts did not show higher risks of CLL compared to daytime workers.

8. In a Korean study from Seoul 100 female medical technologist who worked nighttime had their melatonin levels tested, which were compared to daytime workers.  They measured 1.84 pg/mL of melatonin for the nighttime workers compared to 4.04 pg/mL of melatonin in the daytime workers. The authors felt that this is proof that the diurnal hormone system has been disrupted. Altering the melatonin level also changes the circadian hormone rhythm.

Flatter cortisol curves at night in nighttime workers, also increased diabetes risk

9.A group of 168 female hospital employees doing rotating nightshift work in Southern Ontario hospitals were compared to 160 day workers. Cortisol production was assessed. Cortisol production in day workers and in shift workers on their day shift was similar. However, shift workers on their night shift had flatter cortisol curves and produced less cortisol. The authors felt that this disruption of cortisol production would explain why rotating night shift workers have a higher risk of cardiovascular diseases.

10.A Danish study with female nurses followed 28,731 nurses between 1993 and 2015. Researchers measured the incidence of diabetes in rotating nighttime nurses in comparison to the data from daytime nurses. Night shift workers had a risk between 1.58-fold to 1.99-fold when compared to daytime workers to develop diabetes. The risk for evening shift workers was less (between 1.29-fold and 1.59-fold).

Diurnal hormone rhythm behind health risks of night shifts

Your body has its own rules. It rewards you, if you sleep 7 to 8 hours during the night, but it will penalize you severely, if you turn it upside down. The reason is our built-in diurnal hormone rhythm. A peak of melatonin regulates sleep during the night. Melatonin is released by the pineal gland (on the base of the skull) when it gets dark outside. Daytime wakefulness regulates the release of the stress hormone cortisol from the adrenal glands. These two hormones inhibit each other, cortisol inhibits melatonin and melatonin inhibits cortisol. All the other hormones are also regulated according to the diurnal rhythm: testosterone is highest in the morning, human growth hormone is highest between midnight and 3 AM etc.

Adjustment of the diurnal hormone system

When you work daytime shifts, your diurnal hormone rhythm works just fine. But if you work nighttime shifts, your hormones have to adapt. This is very similar to traveling east or west where you cross several time zones. Your internal diurnal hormone system has to adjust to these changes. Typically it takes 1 day to adjust to a 1-hour time zone difference.

Rotating shift workers have the highest risk of getting sick

In people who work permanent night shifts, the hormone changes stay adjusted and there is no further switching. But most employers want to be “fair” to everybody, so they introduced the rotating night shifts. The publications above show that this is the worst thing you can do. It messes with your diurnal hormone rhythm, and some people never switch completely to the new hours worked. They don’t get enough daytime sleep because the kids are loud during the day etc. The rotating shift workers are running the highest risk of getting sick. The get cancer, diabetes, cardiovascular diseases, obesity, cancer, leukemia, and they have low levels of melatonin.

Health Risks Of Night Shifts

Health Risks Of Night Shifts

Conclusion

Shift workers working constant night shifts is less stressful than the more common rotating shift work. This is where you work night shifts for a period of time. Then the schedule switches to day shift, and you keep on rotating. The least health risks occur with regular daytime work. People exposed to rotating night shifts suffer from poor sleep. They have a higher risk of gaining weight, getting obese and acquiring diabetes in time. They are at a higher risk for heart attacks, strokes and cancer. All-cause mortality is about twofold higher than for workers who work day shifts.

The underlying problem seems to be a disturbance of the diurnal hormone rhythm. Normally this regulates our waking/sleeping rhythm and keeps us healthy. But with nighttime work melatonin production weakens, there is less cortisol production and hormone rejuvenation during rest periods suffers greatly. This weakens the immune system, allows cancer to develop and leads to chronic inflammation causing cardiovascular disease and diabetes. The remedy to prevent this from happening is to catch little naps whenever you can during the day. And, if at all possible, work daytime shifts permanently.

Zika Virus

Recently the question was asked on the news whether it was safe to go to the Olympics in Brazil; so here is some background information about the Zika virus. Zika virus was first isolated from mosquitoes in a forest named Zika forest in Uganda, which was in 1947.

Zika virus belongs into the virus family of Flaviviridae. Other members in that family are dengue fever, West Nile virus, yellow fever and Japanese encephalitis. Since the 1950’s Zika virus has occupied a narrow equatorial belt around the globe (Africa and Asia). But between 2007 and 2016 it spread further to the Americas and to the Pacific. This includes specifically French Polynesia, the Cook Islands, Easter Island and New Caledonia. Since May 2015 Brazil has joined the countries where mosquitoes are infected with Zika virus. This is an important point to know for the coming up Olympics in Rio on August 5 to 21, 2016.

Symptoms of Zika virus

For most people, particularly the young and middle aged ones Zika is  not be that symptomatic. The most common symptoms are a fever, a skin rash, joint aches and red eyes (conjunctivitis). However, when a pregnant woman gets Zika virus, this will likely affect the fetus and will lead to a baby born with a small head (microcephalus), a severe complication from Zika virus. When a woman contracts Zika virus, the virus disappears after about one week. But in men the virus seems to stay longer, particularly in semen. This is why the CDC recommends for men using a condom or refraining from sex when returning from a holiday in a Zika endemic area. It may take up to 8 weeks for the semen to no longer be infective. The CDC recommends that a man who has come down with Zika to use a condom for 6 months.

Treatment of Zika virus

Make sure you get lots of rest. Take acetaminophen for fever or pain. Don’t take aspirin (ASA) or anti-inflammatory medication. Be aware that for between 1 and 3 weeks your blood likely is infectious. You want to avoid a bit from a mosquito and it is sensible to use insect repellants. The same insect could have bitten another person and spread the virus this way. A person who gets the Zika virus depends on the immune system to overcome the infection as there is no cure for this viral infection.

At this point no vaccine against Zika exists. There is research in an attempt to develop a Zika vaccine, which may become available in 2 to 3 years.

Zika virus risk with travel

If you travel to endemic areas, but visit mountainous areas above an elevation of 6,500 feet (2,000 meters) you are safe from Zika transmitting mosquitoes as they do not survive in these heights.

With regard to the Olympic Summer Games in Rio 2016 the CDC recommends to take a few precautions. Use insect repellents. Be aware as a woman that men infected with Zika virus can transmit the virus through sex. If you want to protect yourself from the risk of giving birth to a child with microcephaly, you may decide to use the birth control pill and ask your partner to use a condom. When you return back home, do not plan for a pregnancy for 6 months to avoid the risk.

The only recommendation for the Olympics by the CDC is that pregnant women should categorically not go to the games for fear of getting Zika infection resulting in a bad outcome of the pregnancy with microcephaly.

Microcephaly and other brain abnormalities from Zika virus

The CDC has stated that it is now established that Zika virus can cause microcephaly, but that it likely does not do so in all cases of Zika virus infection.

We know from German measles (rubella) that it can cause serious health risks for the fetus including death.

Zika is similarly neurotropic, meaning that it likes to multiply in nervous tissue including the brain. With rubella there is a vaccine available, which has made it much safer for pregnant women. But with Zika no vaccine is available. The only prevention is to stay away from endemic Zika areas and otherwise use reliable birth control methods.

Zika Virus

Zika Virus

Conclusion

I have briefly reviewed Zika virus in this blog. Unfortunately there are still many gaps in the knowledge of this disease. We need an effective Zika virus vaccine. It would also help to have antiviral antibiotics. Research is necessary to research all of this. For now we need to use prevention and avoid endemic Zika regions by reading updates by the CDC.

High Vitamin D3 Prevents Cancer

In the last few years we learnt a lot about vitamin D3, but the newest thing is that high vitamin D3 prevents cancer.

Researchers at the University of California, San Diego School of Medicine reported that with respect to several cancer types higher doses of vitamin D3 led to less cancer over a period of time.

The cancers investigated were colon cancer, breast cancer, and lung and bladder cancer. People absorb vitamin D3 differently.  The researchers found that the best way to measure vitamin D3 concentration in the body is to use serum 25-hydroxyvitamin D (25(OH)D). In the past people did not pay much attention to this matter. However, several studies including the present study showed that in patients who had a lower level of 20 ng/ml cancer rates were higher.

Comparison of two cohort studies

The researchers used data from two prior studies, a randomized clinical trial of 1,169 women and a prospective cohort study of 1,135 women. The researchers found that the age-adjusted cancer incidence was 1,020 cases per 100,000 person-years in the randomized clinical trial, called “Lappe cohort”. The other prospective cohort study was called the “GrassrootsHealth cohort” where cancer incidence was 722 per 100,000 person-years. The interesting fact was that the Lappe cohort median blood serum level of 25(OH)D was 30 nanograms per milliliter, while the GrassrootsHealth cohort had a higher level of 25(OH)D of 48 ng/ml.

Higher vitamin D levels correlate with lower cancer incidence

This likely explains the lower cancer rate in the GrassrootsHealth cohort. Researchers combined the two trials in order to increase the statistical significance . The striking finding was that above 40 ng/ml the overall cancer risk was more than 71% lower than for the group of people whose level of 25(OH)D was 20 ng/ml or lower. The above ScienceDaily article was based on this scientific study.

Other studies showing high vitamin D3 prevents cancer

AfroAmerican men had less prostate cancer, if vitamin D level was higher

In a 2015 study Afro American men were found to have 71% less prostate cancer, if their serum 25-hydroxyvitamin D level was at least 30 ng/ml or higher.

Prospective study showing high vitamin D levels cancer protective

This 2006 study reported a 14-year prospective follow-up in men where all cancers were counted and blood serum 25-hydroxyvitamin D levels were correlated to cancer incidence. An increase of 25 nmol/L (=10 ng/ml) in predicted serum 25(OH)D level showed an association of a 17% reduction in total cancer incidence, with a 29% reduction in total cancer mortality and a 45% reduction in digestive-system cancer mortality. These investigators stated that it takes about 1500 IU of vitamin D3 increase per day to achieve an increment of serum 25(OH)D increment of 25 nmol/L (=10 ng/ml).

University of Arizona Cancer Center study

A publication from the University of Arizona Cancer Center in Jan. 2016 is more critical of the evidence regarding vitamin D3 and the claim that it lowers cancer rates. The researchers reviewed the cancer literature and found that for colorectal cancer there is a clear inverse relationship between serum 25(OH)D levels on the one hand and rates and mortality of colorectal cancer on the other hand. However, with breast cancer the literature was more divided. Only higher vitamin D levels were related to a lower risk for progression of breast cancer and a lower mortality rate. Randomized, double-blind clinical trials with regard to breast cancer failed to show effectiveness on cancer prevention or reduction of mortality. For prostate cancer conditions were similar with the exception of a study using 4000 IU of vitamin D3 per day, which inhibited progression of prostate cancer.

Mouse model regarding ovarian cancer and vitamin D

In a mouse model using a carcinogen to induce ovarian cancer there was an inverse dose-relationship between vitamin D3 and ovarian tumor development both in tissue culture and in the animal.

How high vitamin D3 prevents cancer

Immune stimulating effect of vitamin D3

Several studies have attempted to speculate how vitamin D3 may prevent cancer. Chirumbolo summarized the literature and noted that vitamin D3 has been shown to function as an immune cytokine stimulating the immune system non-specifically.  Vitamin D3 is also anti-inflammatory and counters insulin resistance and inflammatory kinins in obesity. Flavonoids with their antioxidant activity are also cancer preventing. We know that low levels of vitamin D have an association with higher cancer frequency. This means,. it is important to use vitamin D3 as supplements in our diet.

Chinese study describing action of vitamin D3 in detail

This Chinese study examined the effects of vitamin D3 on cancer prevention. It found that vitamin D3 combines three specific actions in one. Vitamin D3 is anti-proliferative meaning that it stops uncontrolled cell division. Secondly, it has an apoptotic (cell death) effect, which means it supports the removal of cells that are dying. If they are dying, but not removed, cancer can occur from these cell remnants. The third effect of vitamin D3 is that it has differentiating effects in several malignant cell types. When cancer cells are non-differentiated (=more immature cells) cancer can multiply quickly. Mature cells find it more difficult to turn cancerous. This is an effect that controls the speed by which cancer cells divide and how quickly cancer metastasizes.

High Vitamin D3 Prevents Cancer

High Vitamin D3 Prevents Cancer

Conclusion

There still is some confusion about the effects of vitamin D3 regarding cancer prevention. In colorectal cancer the statistics are clear: vitamin D3 can significantly prevent colorectal cancer to a large extent. There are also preventative effects in breast cancer and prostate cancer. But individuals may have to take at least 4000 IU of vitamin D3 or more. This is particularly true in higher latitudes where sunlight exposure is lower in the wintertime. Also, people absorb vitamin D3 differently. For this reason it is important to at least check your serum 25-hydroxyvitamin D levels on a few occasions. This will tell you whether your vitamin D3 supplementation is sufficient. Aim for levels in the 50-80 ng/ml, which is health promoting.

Apart from cancer prevention vitamin D3 is also important for prevention of cardiovascular disease. This is particularly true for diabetes, osteoporosis and Alzheimer’s disease.
