Take Enough Vitamin D3

Many people supplement with 300 to 400 IU of vitamin D3, but do they take enough vitamin D3? There is a simple way of finding out: ask your doctor to order a 25-hydroxyvitamin D blood test.   This will show whether the gut absorbed enough of the essential vitamin. It will also show whether or not your vitamin D3 capsules or tablets were strong enough. It is now generally accepted that a good range of the vitamin D blood level is between 50 and 80 ng/ml. Unfortunately many Americans who come down with various diseases have blood levels of less than 30 ng/ml. Here are some facts about what a lack of vitamin D3 can cause.

Increased risk of mortality with lower vitamin D levels in ICU patients

  1. A New England Journal study from 2009 reported about 1100 patients in Intensive Care Units (ICU). Their average vitamin D blood level was only 16 ng/ml. They tracked the mortality rates depending on the vitamin D blood level. Insufficient vitamin D levels showed an association with a mortality rate of 45%. An intermediate level had a mortality rate of 35%. And a satisfactory level of vitamin D had a mortality of only16%. Between the low level of vitamin D and the normal level there was a 3-fold difference in mortality!
  2. Another study from 2015 repeated the mortality study with 135 ICU patients. Researchers correlated Vitamin D blood levels with mortality rates of patients. When vitamin D levels were below 12 ng/ml, there was a mortality rate of 32.2%. Patients with higher levels of vitamin D had a mortality rate of 13.2%. The authors concluded that vitamin D blood levels were an independent risk factor for mortality. Patients less than 12 ng/ml had a 2.4-fold higher risk of dying than patients with normal vitamin D levels.

Do patients with multiple sclerosis take enough vitamin D3?

Perhaps one of the earliest results of vitamin D3 research was the following observation. More than 90% of patients with multiple sclerosis were deficient in vitamin D blood levels. Their levels were below 20 ng/ml. Other researchers showed that vitamin D could directly tone down the aggressiveness of the immune cells of MS patients. These were the ones that attacked the myelin sheath. As a result of this knowledge it is important for MS patients to take high enough vitamin D3 supplements. When they reach good vitamin D blood levels their MS is better controlled.

Canada as a northern country has 291 MS patients per 100,000 people. Contrast this to 110-140 MS patients per 100,000 people in the northern US (between the 37th parallel and the US/Canadian border). In addition south of the 37th parallel there are only 57-78 cases of MS per 100,000 people. Researchers have concluded that the less sun light people get, the higher the rate of MS in the population will be. However, instead of sun exposure you can supplement with vitamin D3 capsules to get the blood vitamin D levels up to the range of between 50 and 80 ng/ml.

Do stroke patients take enough vitamin D3?

Strokes are very common. About 6.8 million Americans survive a stroke and live with various disabilities. 15% die shortly after their stroke. 40% are left with moderate to severe disabilities. Many require special care.

  1. Studies have shown that patients with the lowest level of vitamin D have the poorest functional outcomes. Moreover, for every 10 ng/ml decrease in vitamin D levels the odds of a healthy recovery 3 months after the stroke fell by about half. This was independent of age and the initial stroke severity.
  2. In another 2015 study from South Korea 818 stroke patients took tests to evaluate whether they had adequate vitamin D blood levels. There was a clear division between those whose levels were higher than 10 ng/ml or lower. When the vitamin D level was higher, there was a 90% better recovery from their stroke after 3 months. In comparison those whose vitamin D levels were below 10 ng/ml had poor recovery rates. Experts say that vitamin D levels should stay in the range between 50 and 80 ng/ml. This will prevent numerous diseases.

Do diabetics take enough vitamin D3?

  1. Vitamin D3 can silence diabetes genes in connection with the right diet and cofactors of zinc and magnesium. A Mediterranean diet can stabilize the metabolism and fight inflammation. Zinc and magnesium are important cofactors in enzymes necessary to prevent diabetes. Vitamin D3 and omega-3intake are helping to control inflammation and preserve beta cells in the pancreas in diabetes patients. This is important for continued production of insulin.
  2. A Chinese research team found that vitamin D3 protects beta cells in the pancreas from dying off. The finding was that vitamin D3 receptors in the insulin producing cells prevented the dying off of these cells, as long as there was enough vitamin D available. Insulin production by the pancreas remained effective. And insulin is vital for long-term survival of diabetes patients. The key for diabetes patients is to take adequate doses of vitamin D3 to protect their insulin producing beta cells.
  3. A 2015 Italian study showed that micro vascular complications in diabetes patients were high, if the vitamin D3 blood levels were low. If patients had high levels of vitamin D3, there were no complications such as retinopathy or nephropathy. But if levels were below 20 ng/ml, damages were significant in the capillaries of the eyes and kidneys.

Do patients with inflammatory conditions take enough vitamin D3?

What do the lining of the arteries, the inflamed joints, a degenerative meniscus and heart attacks and strokes have in common? It is the inflammation that changes the body chemistry. It gets even more complicated, because the extra calories that we consume get stored as visceral fat. This is done automatically when you eat too much sugar and starchy foods. When the glycogen stores are full, any surplus sugar gets metabolized by the liver into triglycerides, fatty acids and LDL cholesterol and gets stored as body fat. The most active fat is the visceral fat between our guts and around our body organs. This produces interleukins and other inflammatory cytokines that circulate in the blood causing inflammation in all our arteries. Interleukin-6 is an inflammatory cytokine. High interleukin-6 levels contribute to causation of various cancers.

This 2015 study from Seattle University followed 218 obese postmenopausal women with a body mass index of larger than 25.0 for 12 months. Both received weight loss intervention and either 2000 IU of vitamin D3 daily or a placebo pill. Both groups lost about 5 to 10% of weight in 12 months. However, the interleukin-6 level of the vitamin D3 group had a reduction of 37.3%. This was in stark contrast to the placebo group where the interleukin-6 level reduction was only 17.2%. This type of research shows the incredible power of vitamin D3. This likely is the reason why several cancer frequencies can show a reduction with regular vitamin D3 supplementation.

Attention deficit disorder and vitamin D3

  1. Other research compared a group of 37 children with attention deficit hyperactivity disorder (ADHD to 37 normal children. Blood levels of vitamin D were 19.11±10.10 ng/ml in the ADHD group and 28.67±13.76 ng/ml in the normal group. Other researchers have found similar findings, establishing that very low vitamin D levels have a connection with ADHD.
  2. A prospective study from Spain involving 1,650 mother-child pairs investigated the effect of mother’s vitamin D level during her pregnancy with the risk for ADHD by the time the child was 4 to 5 years old. Schoolteachers followed the standard test procedures to establish the ADHD diagnosis. The study showed that for every 10-ng/ml increment of the mother’s blood vitamin D level during her pregnancy the children had 11% less ADHD-like symptoms. The authors cautioned that it takes mega doses of vitamin D3 to reach these kinds of results. The usual 400 IU of vitamin D3 per day will not achieve the desired increase of vitamin D3 levels, but amounts of 5,000 IU to 8,000 IU are necessary to achieve this.

Schizophrenia and vitamin D3

A 2014 Meta analysis found that low vitamin D levels have an association with a 2.16-times higher probability of having schizophrenia than controls with normal vitamin D levels. Another study examined whether those patients who had an acute psychosis would have lower vitamin D blood levels than schizophrenia patients in remission or control patients without schizophrenia. Studies compared 40 patients with an acute psychosis to 41 patients in remission and 40 healthy controls. Patients with an acute psychosis had extremely low vitamin D blood levels, while patients in remission had much better vitamin D levels. Healthy controls had the best vitamin D levels.

Absorption and metabolism of vitamin D3

Magnesium plays a central role in activating vitamin D3. This publication points out that magnesium is also necessary for absorption of vitamin D3 in the gut. The activation of vitamin D3 is also partially responsible for vitamin D absorption. Both vitamin D3 and magnesium play an important role in bone and calcium metabolism. The fact that every body cell has vitamin D3 receptors shows how important it is for the maintenance of the body. Many researchers say that vitamin D3 qualifies as a hormone because of the specific effects on cells via vitamin D3 receptors.

Take Enough Vitamin D3

Take Enough Vitamin D3

Conclusion

Vitamin D3 is an important signaling hormone and vitamin that regulates the body’s calcium absorption and is responsible for bone metabolism. Research has shown that the lack of vitamin D3 causes several unrelated diseases, like rickets, multiple sclerosis, and schizophrenia. But other diseases, where a lack of vitamin D3 was present, were diabetes, attention deficit disorder and strokes. When patients with elevated inflammatory markers take vitamin D3 their interleukin-6 levels dropped by 37.3%. To achieve this, patients needed to consume at least 2000 IU. We all should have our vitamin D blood level measured from time to time. It should be between 50 and 80 ng/ml. Too many Americans are deficient in vitamin D3 and come down with the diseases mentioned! Prevention and supplementation go hand in hand. You can prevent a lot of diseases this way.

Close Diabetes Control Prolongs Life

 

A 20-year study showed that close diabetes control prolongs life. A study divided 160 people with diabetes into two groups. The one group continued to get standard care. Yet the other group received a multi targeted, aggressive treatment protocol. As a result after 20 years the group with the intensive treatment protocol lived 7.9 years longer than the group with the standard treatment.

Dr. Oluf Pederson was the senior investigator of the physician team that followed the diabetes group. He said that they concentrated on a number of known adverse factors and treated them aggressively. These factors were first of all high blood glucose values and clotting risks, also high blood pressure and high triglycerides and in addition cholesterol values. Behavior modification was the therapeutic method to get people with risk factors to exercise more, adopt a healthy diet and stop smoking. Medication in select cases also played a role.

More details about the study

The intervention of intensive treatment lasted 8 years. After that the patients were still in a follow-up study for 13 years. At the beginning of the study patients were on average 55 years old and were borderline obese.

The investigation team screened for complications of diabetes. This included screening for kidney disease, heart disease and blindness. Dr. Joel Zonszein, the director of the New York Clinical Diabetes Center at Montefiore Medical Center said: ”These results are impressive and most patients do not receive the correct treatment, according to national surveys.”

Other studies about diabetes  

Foreign studies

Study from Croatia
  • Another study from Croatia involved 200 patients. It concentrated on patients who did not respond to metformin. Physicians used alternative treatment modalities, and they observed and measured blood sugars and hemoglobin A1C in the following 6 months. The study concluded that those patients who received aggressive treatment of their condition did better than those who did not receive the same vigorous approach.
Study from Japan
  • This Japanese study documented that female patients with type-2 diabetes developed kidney damage earlier than their male counterparts.  Consequently, the investigators pointed out how important it is to treat diabetes aggressively to avoid kidney damage.
Study from Singapore
  • This 2016 study from Singapore analyzed retroactively the impact of diabetes on the long-term survival after coronary bypass grafting (CABG).  5720 consecutive patients had their isolated first CABG surgery between 1982 and 1999. The mean follow-up was 13 years. 34.6% of the patients had diabetes, 51% had high blood pressure and 46.6% had elevated blood lipids. The initial mortality after the CABG surgery was 2.4% in the diabetic group and 1.8% in the non-diabetic group. 20-year survival rates following CABG surgery were 30.9% in diabetics and 49.2% in the non-diabetics, an 18.3% difference. The 20-year freedom from cardiac mortality rates was 56% in diabetics and 68.4% in non-diabetics. Other risk factors that led to cardiac mortality were the following: female gender (1.43-fold risk), diabetes (1.51-fold risk), previous heart attack (1.54-fold risk) and a low left ventricular ejection fraction of less than 35% (2.6-fold risk). The conclusion from this study was that long-term survival in diabetics following CABG surgery was much lower than that of non-diabetic controls. Hence the key to improving long-term survival for diabetics is to treat comorbidities like high blood pressure and elevated lipids aggressively as well as getting blood sugars and hemoglobin A1C values under control.

US studies

  • In this US study 558 youth (age less than 21) between February 2012 to July 2015 received follow-up. Between 40% and 50% of these diabetics needed insulin to improve their diabetes. Unfortunately their diabetes showed poor control, as their high hemoglobin A1C values indicated. Median HbA1C was 6.7%, 8.5%, 9.6%, and 9.7% in those with disease duration less than 1 year, 1-2 years, 2-3 years and less than 4  In other words, the longer the young patients had diabetes, the less seriously they took their treatment. Only 33% treated their high blood pressure and only 11% their elevated blood lipids. Microalbuminuria, an indicator of diabetic kidney disease, and non-alcoholic fatty liver disease were present in 5% to 6% of these young diabetic patients. The authors came to the conclusion that there were serious gaps in treating these young diabetics. Further follow-up data of the same group of patients in the coming years will provide further data. In conclusion, the new hemoglobin A1C ranges of 3.8% to 4.9% as the new normal range explains why these youths who do not treat their diabetes properly are at high risk to develop complications from their poorly controlled diabetes.
Heart attacks and erectile dysfunction
  • Heart attacks are more common among patients with uncontrolled diabetes. This US study classified diabetics according to the tightness of their diabetes control. Researchers found examining 606 men and 606 women with diabetes that they could reduce their risk of a heart attack, if they controlled smoking, glycated hemoglobin (hemoglobin A1C), systolic blood pressure, and total and high-density lipoprotein cholesterol. The control of all these risk factors could contribute to the prevention of heart attacks. 35% of men and 45% of women could prevent having a heart attack. A laxer control still would prevent 36% of heart attacks in men and 38% in women. A very aggressive diabetes control could prevent 51% of heart attacks in men and 61% in women. Most noteworthy: close diabetes control prolongs life.
  • Erectile dysfunction (ED) is a big problem among diabetic men. This study from Seattle shows the investigation of 136, 306 men with erectile dysfunction. 19, 236 of these men had diabetes prior to their ED problem. Over a two-year observation period diabetic men had much worse ED problems. As a result they needed to receive secondary line treatments  like penile suppositories or injectables. Others needed tertiary treatments like penile prostheses. In those whose diabetes control was good, oral agents as first-line therapies were usually sufficient.
More studies about risks and benefits of lifestyle
  • Middle-aged women with diabetes have a 4- to 5-fold higher risk for developing heart attacks while men do not show such a higher risk. It is probably particularly important for women to control diabetes when they are diagnosed with it to reduce the risk of coming down with a heart attack.
  • In 2011 Taylor from Newcastle University showed in a group of diabetes patients that he could cure diabetes permanently with an extremely low calorie diet. The trial was simple: he took overweight or obese patients with diabetes and put them on a starvation diet of 600-700 calories per day for 8 weeks. Consequently 43% of diabetic patients received a permanent cure of their diabetes. More info: http://nethealthbook.com/news/cure-diabetes-permanently/

 

Close Diabetes Control Prolongs Life

Close Diabetes Control Prolongs Life

Conclusion

The new hemoglobin A1C ranges that are desirable are between 3.8% to 4.9%. When diabetics bring their hemoglobin A1C level into this range, they do not get complications from their previously poorly controlled diabetes. Close diabetes control prolongs life. But as can be seen from a brief review of the literature physicians tend to be lax, patients are lax, and diabetes is often not well controlled. This leads to erectile dysfunction in males, to heart attacks and kidney failure in both sexes. Blindness and painful diabetic neuropathy are also common complications of poorly controlled diabetes. Amputations from clogged arteries are also among the complications. “Close diabetes control prolongs life” is the new mantra that everybody with diabetes needs to follow.

Lifestyle changes control diabetes and prolong life

As stated above Dr. Taylor from Great Britain has shown that a brief 600 to 700 calorie diet can cure 43% of diabetic patients permanently. Quit smoking, bring the glycated hemoglobin (hemoglobin A1C) into the normal range, control your systolic blood pressure as well as your total and high-density lipoprotein cholesterol. Do all these things, exercise regularly, and your diabetes will be well controlled. Remember: close diabetes control prolongs life!

Young Heart Stem Cells Can Cure Old Hearts

Young heart stem cells can cure old hearts in rats. This is what research at the Cedars-Sinai Heart Institute in Los Angeles found. You may not be that impressed, because this talks about rats and not humans. But this is a brand-new concept, so of course research of animal experiments is first.

The heart experiment

Dr. Eduardo Marbán, MD, PhD, is the research director of the Cedars-Sinai Heart Institute. His idea was to take cardiac stem cells (called cardiosphere-derived cells) from hearts of newborn rats. He injected them into 22 months old rats. The human equivalent for 22 months old rats are older people with older hearts. Within one months of the stem cells’ injections the older rats had normal functioning hearts. Their telomeres were also normal. Telomeres are the caps of the chromosomes of the heart cells. The researchers were astonished to find that the previously short telomeres had become longer. This happened within only one month of the stem cell injections. To Marbán’s surprise the older rats also grew hair faster and gained 20% of their previous exercise tolerance limit. In other words, the injection of heart stem cells had rejuvenated the old rats.

Dr. Marbán has previously shown that exosomes play an important role with stem cell regeneration of old heart cells. These particles from the stem cell donor contain RNA and other growth factors.

Overview of how stem cells can reverse heart failure

Cardiovascular disease includes high blood pressure, coronary artery disease, stroke and congestive heart failure. About 2600 Americans die from cardiovascular disease each day in the US. This is roughly one death every 34 seconds. With old age, if a heart attack does not kill you, congestive heart failure will. With heart failure your heart ceases to pump enough blood through your system. Nutrients and oxygen need to reach all of our cells or it means death for the patient. With the knowledge of this serious background, stem cells have come into the focus in an attempt to combat congestive heart failure.

Animal experiments with stem cells in mice, rats and pigs have shown some progress in restoring better heart function. Researchers used different sources of stem cells, like cardiac stem cells that reside in the heart muscle itself. They also used other stem cell sources. Among these were myoblasts (from muscle), mesenchymal stem cells (from fat tissue) and bone marrow stem cells. Several smaller human trials showed that improvement of heart function was possible following a heart attack. In the procedure the surgeon opened coronary arteries and injected stem cells into the affected damaged heart muscle. How can we assess the result of a successful stem cell treatment? By measuring the left ventricular ejection fraction. This means that the heart can deliver a larger volume of blood every minute. The heart pumps more blood from the left ventricle with each heartbeat than before the treatment.

Other experiments that rejuvenate tissues of older animals

Another line of experiments in this paper shows that certain growth factors are necessary to activate stem cells.

  1. One experiment from the 1950’s describes the stitching together of the skin on their flanks joined an old and a young rat. After this procedure the blood vessels grew and joined the two animals circulatory systems. The older animals knee cartilage damage was no longer there, as the cells from the young animals’ blood had healed the damage.
  2. Research had no knowledge of this fact at that time. But another research group in the 2000’s repeated the experiment and could prove that the stem cells of the young animals activated the growth factors in the old animals.
  3. In 2004 Dr. Rando noted that muscle cells of aging mice were aging because of a lack of stimulation of the local skeletal muscle stem cells. These are satellite cells. Experiments similar to the rat experiment showed that there were factors in the blood of young mice that could re-activate stem cells in the muscles of old mice. Agility and movement of the older mice improved. The improvement in the older mice with knee arthritis disappearing and liver cells rejuvenating was astounding.

More evidence that rejuvenation of heart cells is possible

  1. Amy J. Wagers, a former colleague of Dr. Rando carried on experiments with respect to rejuvenation of hearts in mice. She and her colleagues found what stimulated the hearts of old mice. It was a protein called GDF11 (from young mice).  This 2016 publication describes the action of GDF11.
  2. A 2014 paper describes that GDF11 was able to restore aging muscles to a youthful state. But the researchers were also able to rejuvenate stem cell function in general with GDF11.
  3. Another paper describes that blood from young mice stimulates the brain of older animals to achieve rejuvenation. It is the protein of the young stem cells (called GDF11) and possibly other growth factors to bring about this rejuvenation. It works not only on heart cells, but also on hippocampus tissue in dementia models. This may be important in humans for treatment of Alzheimer’s disease.

“We can turn back the clock instead of slowing the clock down.” Dr. Toren Finkel said. He is the director of the Center for Molecular Medicine at the National Heart, Lung and Blood Institute. He went on to say: “That’s a nice thought, if it pans out.” But others who caution that overstimulation of stem cells could cause cancers say: “It is quite possible that it will dramatically increase the incidence of cancer,” Dr. Irina M. Conboy said, a professor of bioengineering at the University of California, Berkeley. “You have to be careful about overselling it.”

Degenerative changes in humans responding to stem cells

Many degenerative changes in humans respond to stem cell treatments. Are there stem cells present in degenerative tissue in humans similar to the animal experiments described above? Are the stem cells merely providing growth factors so the dormant stem cells jump into action and regenerate? Could it be that in future therapists could give a certain growth factor mix  intravenously to a patient, and the same effect as stem cell injections would be posssible? These are all unanswered questions, but research in the next decade should answer at least some of those questions.

Growth hormone improving heart function in heart failure patients

In 2008 a metaanalysis of human studies of congestive heart failure and treatment with human growth hormone (HGH) injections was a research topic. It showed an average increase of the ejection fraction by 4.3%. There were also increased cardiac output, decreased systemic vascular resistance and improved hemodynamic effects. The question is whether the effect is a direct effect on the heart muscle cells by HGH or whether HGH was recruiting dormant heart muscle stem cells. This is not clear at this point.

Young Heart Stem Cells Can Cure Old Hearts

Young Heart Stem Cells Can Cure Old Hearts

Conclusion

We have entered an exciting period of medical research. Although there is only a record of many animal experiments, there is overwhelming evidence that the same principles are true in humans. Many stem cell protocols for humans have already seen use for various applications. But stem cell treatments for heart disease are still in their early stages. As it becomes obvious from my review of this topic, some patients who were part of clinical trials have already experienced positive results. Congestive heart failure or poor pump performance following a heart attack have improved following various stem cell procedures. In the next few years there likely will be a proliferation of treatment options for patients. Although some critics have pointed out a possibility of cancer developing as a side effect of stem cell treatment, no evidence is noticeable at this point.

Resveratrol Effective In Humans

Resveratrol has been labeled a powerful antioxidant; but is resveratrol effective in humans?

  1. Quack watch says: don’t buy into the hype that resveratrol is effective in humans.
  2. WebMD claims that there would not be enough medical evidence to say that the average person should supplement with resveratrol to receive benefits.

Despite these recommendations the following evidence supports that resveratrol is indeed effective in humans.

Resveratrol effective in humans: high blood pressure patients

A 2017 study of high blood pressure patients examined resveratrol supplementation with two groups, 46 stage 1 hypertension patients and 51 stage 2 hypertension patients. Stage I hypertension had a systolic blood pressure of 140–159 mmHg and a diastolic blood pressure of 90–99 mmHg. Stage 2 hypertension was defined as a systolic blood pressure of 160–179 mmHg and a diastolic blood pressure of 100–109 mmHg. Each subgroup was divided into two groups, one receiving regular antihypertensive medication, and the other group receiving regular antihypertensive medication plus Evelor. Evelor is a micronized formulation of resveratrol. The trial lasted two years. The purpose of the trial was to determine the effect of resveratrol, which was added to the regular antihypertensive medication (or not) to see whether it had blood pressure lowering effects. The interesting result showed that the resveratrol addition was sufficient to bring the blood pressure down to normal levels with only one antihypertensive drug. The control group without resveratrol needed two or three drugs to get the blood pressure under control. In addition, liver function tests showed that resveratrol normalized negative side effects of the antihypertensive drug on the liver. Both liver enzymes, glutamate-pyruvate transaminase (SGPT) and gamma-glutamyl transferase (Gamma-GT) were normal in the group where resveratrol had been added.

Resveratrol effective in humans: diabetes patients

Resveratrol helps diabetes patients. Resveratrol, the bioflavonoid from red  wine is a powerful anti-inflammatory. This antioxidant has several other effects, which make it challenging to measure each effect by itself. This group of investigators managed to simultaneously measure these effects. They found that resveratrol lowered the C-reactive protein by 26% and tumor necrosis factor-alpha by 19.8%. Resveratrol also decreased fasting blood sugar and insulin; in addition it reduced hemoglobin A1C and insulin resistance. The recommended daily dose of resveratrol was 1000 to 5000 mg.

Resveratrol effective in humans: improves bone density

Resveratrol improves bone density in men: 66 middle-aged obese men with an average age of 49.3 years and a mean body mass index of 33.7 were recruited for this randomized, double blind, placebo-controlled trial. The purpose was to study whether there would be changes in bone turnover markers (LDH, an enzyme involved in bone turnover), but also whether bone mineral density (BMD) would increase. Resveratrol was given to a high group (1000 mg per day), a low group (150 mg) and a placebo (fake pills) were given to the third group. The end point was an elevation of the bone alkaline phosphatase (BAP). This was measured in the beginning of the study and at 4, 8 and 16 weeks. The high group of resveratrol had a 16% increase of the BAP throughout the study and a 2.6% in lumbar spine bone density (measured by a trabecular volumetric method). The low resveratrol group showed no bone restoring effect. MJ Ornstrup, MD, the lead investigator said that this was the first time that a clinical team has proven that resveratrol can potentially be used as an anti-osteoporosis drug in humans. She added that resveratrol appears to stimulate bone-forming cells within the body.

Resveratrol effective in humans: anti-aging effects

The Nurses’ Health Study showed that both a Mediterranean diet and resveratrol can elongate telomeres.

The fact that you can have a longer life with a Mediterranean diet is known for some time. But now a study has shown that the reason for a longer life is the fact that telomeres get elongated from the Mediterranean diet. Telomeres are the caps at the end of chromosomes, and they get shorter with each cell division. This is the normal aging process.

The finding of elongated telomeres comes from the ongoing Nurses’ Health Study that started enrolling subjects in 1976. At that time 121 700 nurses from 11states enrolled in the study. In 1980 diet sheets were used to determine who was adhering to a Mediterranean diet. 4676 middle-aged participants were identified to qualify for this study. This diet consists of a combination of vegetables, legumes, fruits, nuts, grains and olive oil. Fish and lean meats were also consumed. The control group followed a regular diet. Between 1989 and 1990 blood tests were obtained to measure telomere length in white blood cells. It is known that smoking, stress and inflammation shortens telomeres. The lead author Marta Crous-Bou stated that overall healthy eating was associated with longer telomeres compared to the control group. But the strongest association was found in women who adhered to the Mediterranean diet when compared to the controls. For the best diet adherence score there was a 4.5 year longer life expectancy due to slowed telomere shortening.

Longer telomeres have been found to be associated with the lowest risk to develop chronic diseases and the highest probability of an increased life span. I have reviewed the importance of lifestyle factors in this blog where I pointed out that Dr. Chang found a whole host of factors that can elongate telomeres by stimulating telomerase. It has been shown in humans that increased physical activity elongated telomeres. So did vitamin C, E and vitamin D3 supplementation, resveratrol, a Mediterranean diet and marine omega-3 fatty acid supplementation. In addition higher fiber intake, bioidentical estrogen and progesterone replacement in aging women and testosterone in aging men, as well as relaxation techniques like yoga and meditation are also elongating telomeres.

Aging is due to shortening of telomeres. Elongation of telomeres by resveratrol leads to prolonged life (or anti-aging).

Resveratrol effective in humans: resveratrol and cancer

As this overview shows, it seems that several mechanisms of action give resveratrol the power to be an anticancer agent. Resveratrol is anti-proliferative and has anti-angiogenesis mechanisms. In addition resveratrol stimulates apoptosis, which is programmed cell death. All these actions together help resveratrol to have anticancer properties. Resveratrol can also be used in combination with other cancer treatments, which improves survival figures. As the link above explains, more cancer clinical trials with a variety of cancers and larger patient numbers are required, but many smaller clinical trials have already been very successful showing efficacy of resveratrol as a chemotherapeutic agent.

In this 2015 publication about malignancies and resveratrol an overview is given about the use of resveratrol and cancer treatment. It summarizes that the development of cancer is a multifactorial process that involves the 3 stages of initiation, promotion and progression. One of the cancer promoting factors is chronic inflammation. Resveratrol has been shown to be anti-inflammatory. At this point it is not clear how the animal experiments will translate into the human situation. More clinical observations are necessary.

Resveratrol effective in humans: cardiovascular disease

Resveratrol has beneficial effects on preventing hardening of the arteries, diabetes, various cancers and inflammatory conditions like Crohn’s disease and arthritis. As this link explains resveratrol also stimulates the antiaging gene SIRT1 by 13-fold. This confirms the anti-aging effect of resveratrol. This 2012 study has also confirmed that resveratrol from red wine is what is responsible for the “French paradox” (longer life expectancy despite high saturated fat intake).

Resveratrol effective in humans: polycystic ovarian syndrome 

Polycystic ovarian syndrome could be significantly healed with resveratrol in a randomized, double blind, placebo-controlled trial. It involved 30 subjects who completed the trial. 1500 mg of resveratrol or placebo were administered daily for 3 months. Serum total testosterone was decreased by 23.1% at the end of 3 months in the experimental group versus the placebo group. There was also a decrease of dehydroepiandrosterone sulfate of 22.2%. Fasting insulin level was reduced by 31.8%. At the same time insulin sensitivity was increased by 66.3%. The authors concluded that resveratrol had significantly reduced ovarian and adrenal gland male hormones (androgens). This may be in part from the drop in insulin levels and the increase of insulin sensitivity.

Resveratrol effective in humans: anti-arteriosclerotic effects in diabetics

A double blind, randomized, placebo-controlled study was done on 50 diabetics. The cardio-ankle vascular index (CAVI) was used to determine arterial stiffness. The purpose of this study was to determine the effect of resveratrol on the stiffness of arteries in a group of diabetics and compare this to a placebo. Diabetics are known to have premature hardening of the arteries (arteriosclerotic changes). After 12 weeks of taking 100 mg of resveratrol per day there was a significant reduction in arterial stiffness in the experimental group, but not in the placebo group. Blood pressure also decreased by 5 mm mercury (systolic) in the experimental group.

Resveratrol effective in humans: ulcerative colitis patients

56 patients with mild to moderate ulcerative colitis received 500 mg of resveratrol or placebo and were observed for 6 weeks. This was a randomized, double blind, placebo-controlled pilot study. Bowel disease questionnaires were used to assess the bowel disease activity before and after the treatment. The resveratrol group decreased the disease activity significantly, but it also increased their quality of life. Blood tests showed that this improvement occurred as a result of reducing oxidative stress by resveratrol.

Resveratrol effective in humans: Alzheimer’s disease prevention

Here is a study where 52 Alzheimer’s patients were divided into two groups; one group was given 200 mg of resveratrol for a number of weeks, the other group placebo pills. There was a significant improvement in memory tests in the resveratrol group and functional MRI scans showed better functional connectivity in the hippocampi of the subjects. It is known that the hippocampus is the seat for short-term memory, which is lost in Alzheimer’s patients.

Resveratrol Effective In Humans

Resveratrol Effective In Humans

Conclusion

Resveratrol has a long history of showing evidence of improving health. It does so by countering oxidation of LDL cholesterol, which lessens hardening of arteries. This prevents heart attacks and strokes. Resveratrol is also a powerful anti-inflammatory, which helps patients with diabetes, with Crohn’s disease and arthritis. There is even a cancer preventing effect of resveratrol because of anti-proliferative and anti-angiogenesis effects as well as stimulating apoptosis. Because of these combined anticancer properties resveratrol is a chemotherapeutic agent that can be combined with conventional anticancer drugs.

There are enough randomized, double blind, placebo-controlled trials in humans to show that resveratrol is effective in preventing and treating several disease conditions. The medical establishment claims that there would not be enough medical evidence to say that the average person should supplement with resveratrol to receive health benefits. After my review outlined above I come to the opposite conclusion. It is quite clear that resveratrol has several important healing properties. It can improve diabetes; prevent hardening of arteries, lower blood pressure, attack osteoporosis and prevent Alzheimer’s disease. I have been taking 500 mg of resveratrol daily for years. It has not harmed me.

Death From Heartburn Drugs

A study was recently published showing that death from heartburn drugs can come early, when compared to controls. The study was published in June 2017 in the online British Medical Journal Open. The researchers were located at the Washington University School of Medicine, Saint Louis, Missouri, USA.

349, 312 US veterans on proton pump inhibitors (PPI) were compared to an equal amount of veterans on conventional H2 blockers. Over a follow-up period of 5.71 years there was an increased risk of death of 25% when patients took PPI drugs. It did not matter to what the PPI group was compared, there were always more deaths in the PPI group compared to other control groups.

Causes of death

According to the senior author, Dr. Ziyad Al-Aly many deaths were due to kidney disease, dementia, fractures, pneumonia, Clostridium difficile infections and cardiovascular disease. Out of 500 patients who took the PPI drug there was one death within one year. But over the years the deaths increased. Dr. Al-Aly thinks that the PPI drug is interfering in some way with the genetic expression of some genes and suppressing others. These genetic differences may explain the early deaths.

As this was a retrospective study, it can only show an association of PPI drugs with earlier deaths, but this does not prove causation. It would require a prospective random study to prove causation.

Other studies regarding the risk of PPI drugs

  1. An Icelandic study from May 2017 showed that there was a 30% increased risk of fractures in males and females following PPI drugs when observed over 10 years. Opiates were associated with an almost 50% risk, sedatives with a 40% risk of increased fractures. Control groups of NSAIDs, statins and beta-blockers showed no increased fracture risk, nor did histamine H2-antagonists.
  1. An article from March 2017 is a critical review of the safety of PPI drugs. It notices that with long-term use there are adverse effects like fractures of the long bones, enteric infections and hypomagnesemia. PPI’s can increase the risk for heart attacks and can cause kidney disease and dementia. One of the problems is that gastroesophageal reflux usually dictates the long term use of anti acid drugs like PPI’s, but the longer patients are taking these drugs, the higher the death rate and side-effect rate. The physician should only use PPI drugs initially and after a few weeks switch to the less potent histamine H2-antagonists (like ranitidine).
  2. A Danish study from April 2017 noted an increased risk for listeriosis in patients who were on PPI drugs. Over 5 years there was a 2.81-fold higher risk of developing listeriosis in patients on PPI’s compared to a control group. If patients were on corticosteroids and a PPI the risk was even higher, namely 4.61-fold increase to develop listeriosis. In contrast, the use of histamine H2-antagonists was associated with a risk of only 1.82-fold of developing listeriosis.
  1. In a Dec. 2016 study from Dublin, Ireland patients older than 65 were examined with regard to their PPI drug use. Data was compiled for 1997 and for 2012. It was noted that the maximal PPI dose for long-term use was prescribed to 0.8% of individuals in 1997 and to 23.6% in 2012. The risk of getting high dose PPI drugs prescribed in 2012 was 6.3-fold compared to 1997. Examination of the health records showed that the indication for prescribing PPI drugs was not associated with significant gastrointestinal bleeding risk factors. The study concluded that there was definitely room for improving prescribing habits.
  1. This January 2016 paper describes the standard treatment of H. pylori and gastric and duodenal ulcer treatment, which involves the triple therapy consisting of a PPI and two antibiotics. It pointed out that this treatment protocol “improves healing and prevents complications and recurrences”.
  2. A paper from Leipzig, Germany dated July 2016 reviews the usage of PPIs. It mentions that there has been a significant increase of prescriptions in the past 25 years. Patients on PPI’ are at a greater risk for fractures. There is also a risk of low B12 levels from malabsorption of B12. This should be checked from time to time, and if necessary B12 injections should be given.
  3. A Canadian study from May 2015 found that Clostridium difficile infections (CDI) were linked to chronic antibiotic use or to prolonged use of high doses of PPI drugs. There was a 1.5-fold risk of recurrent CDI in patients older than 75 years who were taking PPI drugs continuously. There was a 1.3-fold recurrence of CDI after antibiotic re-exposure.

Alternative remedies for heartburn

  • Dr. Weil recommends the use of deglycyrrhizinated licorice (DGL) for heartburn or early ulcers.
  • Here is a clinical study with 56 patients with duodenal and gastric ulcers that was published in 1968. It could be shown both radiographically as well as clinically that the ulcers healed and that stomach spasms subsided with DGL treatment. At that time it was not known that DGL had antibacterial effects and that often chronic heartburn, stomach and duodenal ulcers can be made chronic by H. pylori infections that are simultaneously present.
  • A December 2016 study showed that probiotics could be a valuable adjunct in triple therapy for H. pylori infection. The study also points out that H. pylori is present in about 50% of the world’s population.

Antibacterial effects of DGL

  • A paper of December of 2012 shows that an important tooth decay bacterium responds to DGL.
  • In a 1989 study 20 patients with aphthous mouth ulcers were followed. DGL mouthwash led to a 50 to 75% improvement in 15 patients within one day of treatment and by the 3rd day there was complete resolution.
  • Here is a suggestion of a four-step approach against H. pylori.
  • DGL has been shown to be useful in gut regeneration in patients with Clostridium difficile infection.

Discussion

I started with a review of a recent paper that pointed out the side effects of PPI drugs. PPI’s are used for acid reflux disease, stomach and duodenal ulcers, either alone or as part of the triple therapy. Because many of these problems are associated with a chronic infection of H. pylori, I reviewed the literature surrounding deglycyrrhizinated licorice (DGL), a natural antacid remedy. It turns out that DGL can be quite useful either as a parallel treatment or instead of the triple therapy.

The problem over the past 25 years is that physicians have been treating acid problems with higher and higher doses of PPI’s. They are also using ASA prophylaxis against heart attacks and strokes more often. This has caused gastric erosions that are bleeding, which in turn caused physicians to prescribe more PPI’s. The side effects of PPI’s can be viewed as iatrogenic (doctor- induced) disease. This is an artificial disease that occurs from the side effects of overprescribed medicine. PPI’s are a very useful short-term anti-acid medication. But this medication should not be used for more than 4 to 8 weeks. But as patients receive years and years of this medication, serious problems like heart attacks, fractures, kidney disease, dementia, and pneumonia as well as Clostridium difficile infections become the consequence. Overall there was an increase of the death rate of 25%.

It sounds quite reasonable that doctors should return to a more conservative approach as the FDA has suggested. Alternative natural methods including DGL and probiotics can also be utilized.

Death From Heartburn Drugs

Death From Heartburn Drugs

Conclusion

A recent study from the online British Medical Journal Open has pointed out a high death rate among long-term proton pump inhibitor (PPI) drug users. These drugs are used to suppress acid formation in the stomach. They are helpful, if there are significant gastrointestinal bleeding risk factors present. But prolonged use of PPIs causes severe side effects as described, including a chronic persistent Clostridium difficile infection (CDI) of the gut that can become resistant to antibiotic therapy. In cases of recurrent CDI one important step is to discontinue PPIs. The physician should consider switching to one of the conventional histamine H2-antagonist drugs (like ranitidine). Overusing PPIs in an older population is not responsible, as this leads to disease that is caused by a physician! There is no need for this to happen. The prescribing physician has to exercise caution and restraint and the patients, and their loved ones need to be aware of multidrug interactions. PPIs belong to the drugs that are eliminated in the liver through the cytochrome P450 enzyme system (CYP2C19). But this enzyme system interfering with the drug elimination process may also eliminate other drugs taken by the patient. The end results can be toxic drug levels of PPIs. It can potentiate the side effects and become responsible for the 25% increased risk of death when the patient takes PPI drugs chronically. Even though PPIs are the newer medication, newer does not always mean better.

What Your Shopping Cart Reveals

What your shopping cart reveals is what I studied on several of our trips to the US. As I am retired, my wife and I travel quite a bit in the US and find it interesting to watch what people place into their shopping carts.

Typical shopping cart I have observed

The typical shopping cart in a US grocery store seems to consist of white bread, pizza, bacon, hamburger meat, potato chips, cookies, cornflakes, grapes, celery, peppers, strawberries and apples. In addition many people buy prepared breaded chicken strips, milk and an assortment of fruit yogurts.

I like to comment on each of these items, what I am thinking and what precautions you need to be aware of.

White bread and pizza

The problem with white bread and pizza is the wheat, which nowadays is Clearfield wheat. A chemical company from Germany was able to chemically modify the genes of wheat in the 1960’s and 1970’s; in addition they used radiation of the seeds. The farmers liked that the new wheat (called Clearfield wheat) grew with stronger roots, shorter final stems and much larger grains so the yield per acre was higher. This type of wheat was patented under the name of Clearfield wheat and sold all around the world. What was not publicized at the time was that the gliadin content increased manifold from the composition of wheat strains used for thousands of years before. Gliadin gets rid of the glue like substance between the gut cells and causes leaky gut syndrome, something that I heard mentioned at many lectures at several of the Anti-Aging conferences of A4M in Las Vegas. This leads to exposure of immune cells to foreign proteins from the gut, which causes the immune system to hyper react with autoimmune antibodies. As a result, many persons react to wheat with indigestion and digestive problems. They may believe that they react to gluten. It is true that Clearfield wheat also has a higher gluten contents. But any tests for celiac disease will come up empty.

We don’t want to eat this as bread, burgers or pizza: but all of them are baked with the wheat that has been chemically force-hybridized into Clearfield wheat.

Bacon and hamburger meat

A prospective study of 72,113 women over 18 years found a definitive relationship between dietary patterns and cancer and heart attacks. A prudent diet with a high intake of vegetables, fruit, legumes, fish, poultry, and whole grains had a very low cancer and heart attack rate. Conversely a Western diet consisting of high intake of red meat, processed meat, refined grains, French fries, and sweets/desserts led to a higher cardiovascular mortality risk of 22% and a higher cancer mortality risk of 16%.

There is another question you should ask: is it grain-beef or is the beef grass-fed?

Meat from grass-fed beef contains 5-times the amount of omega-3 fatty acids compared to corn- or grain-fed beef. Another issue is corn, if that is fed to beef cattle. There is obviously a deliberate marketing drive claiming that corn-fed beef would have a superior taste.

This link shows that the producers only care about their profit and how much of corn-fed beef they can sell. They do not mention that corn is a GMO crop, so this feed is somehow incorporated into the meat. No one has done long-term experiments to ensure that this meat is safe to eat. Moreover, we do know from measurement that corn-fed meat contains much less omega-3 fatty acids and much more omega-6 fatty acids than grass-fed beef. Cows are meant to be grass-feeding animals. If you want to stay healthy, eat grass-fed beef, but do not consume too much or you put yourself at risk for gout from purine metabolites. Corn-fed and grain-fed beef cattle have a lot more infections including liver disease. To control this, the animals are receiving antibiotics. These antibiotics end up in the meat, which can produce superbugs. These superbgs can enter into humans through the food chain.

Bacon is another food that is not only full of saturated fat, but it contains additives, such as sodium nitrite. Give the matter some thought before you put hamburger meat and bacon into your shopping wagon!

What’s wrong about potato chips, cookies, and cornflakes?

1. Potato chips

Potatoes are rich in carbs, but they are empty carbs. Their glycemic index is in the 70 to 80 ranges. I avoid any carbs that exceed 55 (the upper limit of the low-glycemic index). Strangely enough by the time potatoes are processed into potato chips, the glycemic value is only 51, but this is deceiving. The potatoes have been processed in fat and with tons of salt. We now have a product that surely will be bad for your arteries and cause high blood pressure over the long haul. Another important fact is that potatoes belong to the 12 dirty dozens fruit and vegetables that are heavily sprayed with pesticides (see below).

2. Cookies

Cookies are a mix of various ingredients. Here is a recipe for cookies. This is even a better than average quality cookie recipe as they used unsalted butter as a fat source. In many recipes they use margarine, which is an inferior fat. It contains free radicals from the manufacturing process. It is derived from omega-6 fatty acid vegetable oils. But the worst ingredients of cookies are the nutritionally empty white flour and the sugar. Both together are digested, absorbed as sugar into your blood, and a huge insulin response occurs after you have eaten it. Even the cheap chocolate used for the chips is full of unhealthy table sugar causing your pancreas to overproduce insulin.

3. Cornflakes

As mentioned above corn is a GMO crop and we do not know the long-term effects of GMO food on humans. There are more and more reports about gut dysbiosis, leaky gut syndrome and autoimmune diseases as a result of the breakdown of the gut barrier. Pro-GMO advocates deny these possibilities. I play it safe and stick to organic fruit and vegetables. But cornflakes are also high on the glycemic index (between 77 and 93). Usually there is sugar mixed in, and the starchy component consists of empty calories. It is simply not a sensible food choice!

The dirty dozen: grapes, celery, peppers, strawberries and apples

It is known for some time that certain foods are more contaminated with pesticides than others. Some of these fruit and vegetables contain between 13 and 15 different pesticides from spraying, as this link describes. Potatoes are one of the top contaminated crops among the dirty dozen.

Why is it important to know which crop is contaminated with pesticides? Pesticides are immune disruptors. Vegetables that are supposed to be healthy for us contain residues from insecticides and herbicides that have estrogen-like activities called xenoestrogens.They are known to cause breast cancer in women and prostate cancer in men.

Breaded chicken strips, milk and fruit yogurt

1. Chicken strips

Chicken are fed arsenic type antibiotics for faster growth.

The only way how to protect yourself from this contamination is by buying organic chicken, which I have done since 2001. Also, don’t buy breaded “anything” This brings us back to the wheat story mentioned under “White bread and pizza” above.

2. Milk

Milk in the US often contains antibiotics and genetically modified bovine growth hormone (rBGH), which can cause various cancers in humans as this link shows. Recombinant BGH is banned in Europe and in Canada.

3. Yogurt

Most people like fruit yogurt, which is full of sugar and fruit syrup. Plain yogurt, sweetened with a bit of stevia is healthy. But the moment it is adulterated with minimal amounts of fruit, and high amounts of sugar,this “fruit yogurt” leads to weight gain and hardening of arteries. The best yogurt product is organic 1% or 2% plain yogurt. Use fruit of your choice to make a real fruit yoghurt!

What Your Shopping Cart Reveals

What Your Shopping Cart Reveals

Conclusion

Life is all about decisions. I like to make healthy food choices for myself. When I go grocery shopping, I notice that many people do not seem to give much thought to what they are purchasing. They likely also have never read the details about the type of facts I mentioned above. The ingredients that people buy at the grocery store are the ingredients of the Standard American Diet, a sad state of affairs indeed.

The key is to avoid wheat products because Clearfield wheat leads to leaky gut syndrome and autoimmune diseases. Next avoid processed foods and added sugar. What I have not mentioned above is the importance of cutting down on omega-6 fatty acids and to increase omega-3 fatty acids (fish, fish oil supplements). Omega-3 fatty acids are anti-inflammatory. Omega-6 fatty acids stimulate the arachidonic acid pathway leading to hardening of arteries and arthritis. This leads to stents of the coronary arteries and joint replacements of the hips and knees.

Avoid the dirty dozen of crops and buy them organic instead. Avoid milk products in the US; instead buy them organic to avoid exposure to recombinant bovine growth hormone.

It takes a bit of homework and re-education to eat healthy foods. Start reading labels! If a ten year-old cannot read the name of an additive, it should most likely be a signal for you not to buy this product! The more processed food is, the less nourishing it is likely to be. It is not a huge effort to educate yourself about products, but it does take time to steer away from old habits that are not the best for your health. Ultimately your efforts will pay dividends in terms of good health for years to come!

Prevention Of Telomere Shortening

Dr. Mark Rosenberg gave a talk on prevention of telomere shortening. This was presented 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 Clinical Value of Telomere Testing”.

What are telomeres?

Telomeres are the caps at the end of chromosomes. They are very important in the aging process. Prematurely shortened telomeres are linked closely to all major diseases like cardiovascular disease, cancer, diabetes and more. Telomeres are also a measure of the aging process. Aging occurs due to a decrease of the number of cells in organs and/or because of a lack of functioning of these organs. Telomeres get shortened every time a cell divides. But when the telomeres are used up, there comes a time when cells can no longer divide. These cells become senescent cells or they enter apoptosis (programmed cell death).

The senescent cells can become a problem when they get transformed into cancer cells and their telomeres lengthen again. These cancer cells divide rapidly and this can become the reason why cancer patients to die.

What is the significance of telomeres?

Telomere dysfunction is the first sign that the telomeres are getting shorter in a person compared to the average telomere length in a comparable age group. This is not only important for aging, but also has clinical implications. The shorter telomeres are, the higher the risk for cardiovascular disease. Telomere length also provides prognostic information about the mortality risk (risk of dying) with type 2 diabetes and for many cancers. Many physicians incorporate a telomere blood test into periodic health checks, if the patient can afford it.

Interventions that help telomere length

Here are a number of things we can do to lengthen our telomeres.

  1. Rosenberg mentioned that the strongest effect on telomere lengthening comes from caloric restriction and weight loss. 80 years ago they showed at the Cornell University that rats put on calorie restriction had a 30% increase in their mean and maximum lifespan. Many research papers have confirmed that the same is true in man and that the common denominator is telomere lengthening.
  2. Next are regular physical activity, meditation, reduction of alcohol consumption and stopping to smoke.
  3. Taking antioxidants and omega-3 fatty acids regularly will also lengthen telomeres.
  4. Improving one’s dietary pattern by adopting a Mediterranean type diet that contains cold-pressed, virgin olive oil.
  5. Telomerase activators. Here is some background on the TA-65 telomerase activator, which is based on Chinese medicine. A one year trial was completed with 250 units and 1000 units of TA-65 per day. The lower dose (250 units) showed effective telomere lengthening, while the placebo dose did not. The 1000 unit dose did not show statistical significance.

Should you wish to take TA-65, only take 250 units per day, not more.

Cancer and telomeres

There is a strong correlation between cancer and telomere shortening. When cells are at the brink of dying toward the end of their life cycle the telomeres get shorter and shorter. This is the point where the cells can turn malignant. Certain genetic abnormalities help the malignant transformation, like 11q or 17q deletions or a p53-dependent apoptosis response. Once cancer cells have established themselves they activate telomerase in 85% of cases. In the remaining 15% of cancer cases telomeres are activated through telomerase-independent mechanisms. Here are a few examples.

CLL

CLL stands for chronic lymphocytic leukemia. It is a disease of the aging population. At age 90 people’s bone marrow cells have a telomere length of only 50% of the length at birth. This is the reason that in older age CLL is more common. Researchers observed a population segment and found that the shorter telomeres were, the poorer the overall prognosis and overall survival for CLL was.

Lung cancer

In patients with non-small cell lung cancer the telomerase activity was examined. When telomerase activity was present, the 5-year survival was only 55%. When telomerase activity was absent, the prognosis was 90% survival after 5 years.

Prostate cancer

  1. Telomere shortening in stromal cells was found to be associated with prostate cancer risk. Men with shorter telomere length in stromal cells had a 266% higher risk of death compared to men with normal telomere length.
  2. Another study took blood samples and determined the telomere length in lymphocytes (the immune cells). Those men who came down with prostate cancer within a year after the blood sample was taken had short telomeres. The risk for prostate cancer in these patients was 355% higher than in the prostate cancer negative controls.

Yet another study looked at surgical tissue samples from 596 men that

Underwent surgery for clinically localized prostate cancer. Patients whose samples showed variable telomere lengths in prostate cancer cells and shorter telomeres compared to prostate samples with less variable telomere length and longer telomeres had a much poorer prognosis. They had 8-times the risk to progress to lethal prostate cancer. And they had 14-times the risk of dying from their prostate cancer.

Breast cancer

Breast cancer is diverse and consists of cases that are genetically inherited (BRCA1 and BRCA2), but there are also cases where the cancer is local or more advanced (staging). In families with mutated BRCA1 and BRCA2 telomeres are significantly shorter than in spontaneous breast cancer. Increased telomerase activity in breast cancer cases is directly related to how invasive and aggressive the breast cancer is.

  1. One study was shown where blood leukocytes were analyzed for telomere length in 52 patients with breast cancer versus 47 control patients. Average telomere length was significantly shorter in patients with a more advanced stage of breast cancer than in early breast cancer. Mutated HER patients had the shortest telomeres. It follows from this that checking for the HER status and blood telomere testing adds to the knowledge of potential cancer development and prognosis.
  2. Short telomere length was associated with larger breast tumors, more lymph node metastases and more vascular invasion. More aggressive breast cancer cells have higher telomerase activity. More than 90% of triple negative breast cancers have short telomeres.

CNS disorders and telomeres

Dr. Rosenberg presented evidence that shorter telomeres are associated with dementia. But dementias with Lewy bodies and Alzheimer’s disease are also linked to short leukocyte telomeres. The length of blood telomeres predicts how well stroke patients will do and how people with depression will respond to antidepressants.

Cardiovascular disease and telomeres

Our blood pressure is kept constant through the renin-angiotensin-aldosterone system. When this system is not stable, our blood pressure shoots up and causes cardiovascular disease. This is tough for the heart, as it has to pump harder against a higher-pressure gradient. A study of 1203 individuals was examining the connection between leukocyte telomere length and renin, aldosterone and angiotensin II activity. It concluded that oxidative stress and inflammatory responses affect the telomere length of leukocytes and that the more stress there is in the renin-angiotensin-aldosterone system, the more cardiovascular disease develops. The conclusion of the study was that the overall cardiovascular stress leads to shortening of leukocyte telomeres.

Prevention Of Telomere Shortening

Prevention Of Telomere Shortening

Conclusion

Telomere length testing from a simple blood test will become a more important test in the future as hopefully the cost comes down (currently about 300$). It can predict the general aging status by comparing a single case to the general telomere length of the public. But it can also predict the cancer risk, risk for mental disease and cognitive deficits (Alzheimer’s disease). In addition your cardiovascular status is also globally assessed with this test. What can be done, if the test comes back with short telomeres?

It allows you to change your lifestyle and adopt a healthy diet. You can exercise regularly, take antioxidants and meditate. There are even telomerase activators that are gradually becoming more known. They lengthen the telomeres. The cost of telomerase activators will likely still be a problem for some time. All in all telomere length tests are here to stay, but effective intervention at this point is largely limited to healthy lifestyle choices. This is good news: healthy lifestyle choices like non-smoking, exercise and avoiding non-processed foods are either free or have a reasonable price tag. Telomerase activators are big business and at this point not really affordable!

Cancer By Chance

A new theory talks about cancer by chance. In other words, it likely is mostly bad luck when cancer develops. Mathematician Cristian Tomasetti and cancer geneticist Bert Vogelstein of Johns Hopkins University in Baltimore, Maryland developed a new model of cancer development. They found that stem cells in different organ systems divide at different rates. The faster they go through cycles of cell divisions, the higher the chances of a mutation. The mutations happen in the genetic material and can lead to cancer. Dr. Vogelstein applied this model to 32 different cancer types and found the following.

  • 66% of cancers: cancer-promoting mutations develop by chance during cell division in various organs
  • 29% of cancers are due to environmental causes
  • 5% of cancers are inherited

Stem cells in organs can turn into cancer by chance

Key to the new theory of “cancer by chance” is that cancer likely is developing from stem cells in different organs. Different stem cells have different rates of stem cell divisions.

In pancreatic cancer they found that 5% were inherited, 18% were from environmental factors (smoking) and 77% came from chance mutations. This data was derived from the Cancer Research UK database.

For prostate cancer the rate of spontaneous mutations is 95%. When all of the cancers are looked at about 1/3 of cancers are due to either environmental or inherited factors, but 2/3 of all cancers are due to random mutations (“bad luck mutations”). They pointed out this fact in their first publication.

With the second publication, as mentioned in the beginning, Vogelstein and Tomasetti concentrated on 17 common cancers in 69 countries. They searched 423 international cancer databases. Again they found that the more stem cells divided in an organ, the more random mutations occurred. This caused cancers in that organ.

Here are a few examples for lifetime stem cell divisions:

  • Colon: 6,000 cell divisions in stem cells of the colon
  • Breast: 300 cell divisions in breast stem cells
  • Lung: only 6 cell divisions in lung stem cells

Colon cancer is very common because of the high stem cell division rate. But they also looked at environmental factors. For instance, lung cancer is rare in non-smokers because stem cells in lungs divide slowly. However, the carcinogens from cigarette smoke add a huge environmental risk. The end result: there is more lung cancer in smokers. Vogelstein said that with every stem cell division there is the creation of three new cell mutations because the body has a “poor copying machine”. During meiosis DNA breaks can occur that lead to mutations. Once they occurred, they continue to get copied.

Environmental factors versus cancer by chance

In the first paper the medical community was critical about how the authors had overemphasized that two third of cancer is caused randomly. So in the second paper Vogelstein and Tomasetti mentioned quite a bit how a change of the environment can change the final outcome of developing cancer.

This is also reflected in this summary from the CNN.

They mentioned that one mutation is not enough to cause cancer. You need three or four such mutations. As we get older there is a higher likelihood that we accumulate this number of mutations, and cancer can develop. But if we exercise, stop smoking and avoid red meat, this can contribute to a much healthier environment in the dividing stem cells. In this case we may not accumulate enough stem cell mutations in our lifetime to come down with cancer.

There is a problem with prostate cancer as indicated in this German summary of Vogelstein and Tomasetti’s work.

Japanese men have an extremely low rate of prostate cancer, namely 1/25th of the rate in the US. When Japanese men immigrate to the US, it does not take long before their risk is the same as that of US men. This is a classical case of the importance of environmental factors in cancer causation. Song Wu has pointed out in a publication in Nature that in his opinion Vogelstein and Tomasetti did not pay enough attention to extrinsic (environmental) factors in the causation of cancers.

This could explain the prostate cancer conundrum just mentioned. There may be more xenoestrogens in the environment in the US when compared to Japan, and this may have caused the additional prostate cancers when Japanese men moved to the US. Xenoestrogens are estrogen-like hormones in the environment, which can cause prostate cancer.

Prevention undermines “cancer by chance”

The role of prevention is likely larger than previously estimated. Now that we know that on average 2/3 of all cancers are due to chance mutations, it is important to realize that prevention and early detection play an enormous role.

  1. Most cancers can only be cured in stage 1 and stage 2 out of 4 stages. And this is only the case when the mutated stem cells are removed along with the clone of cancer cells.
  2. In terms of reducing the risk for lung cancer this means to stop smoking.
  3. With colon cancer it means having regular colonoscopies where the suspicious polyps are removed.
  4. For prostate cancer it means to do a mapping biopsy and to do cryoablation therapy, which has a prostate cancer vaccination effect as well.
  5. Not all cancers can be diagnosed early. Pancreatic cancer is such a difficult to diagnose cancer. But screening methods have been developed that are more sensitive and very specific such as the Oncoblot test.  With this test even cancer of the pancreas can be diagnosed years before it would be clinically detectable.
  1. We do know that chronic inflammation can lead to cancer. It makes sense therefore to start with an anti-inflammatory diet like the Mediterranean diet. Fish oil is also anti-inflammatory.
  2. Add to this regular exercise, as we know it reduces the risk for cancer development and strengthens your heart and lungs.
  3. Vitamin D3 can reduce cancer risks in both males and females. When vitamin D3 was given and blood 25-hydroxyvitamin D levels were above 40 ng/ml, the breast cancer rate was reduced by 71% compared to a low vitamin D3 group. Similarly in men the prostate cancer rate dropped by 71% with vitamin D3 supplementation.  There is more good news with vitamin D3. You can read about it in the link.
Cancer By Chance

Cancer By Chance

Conclusion

The causes of cancer have always been by chance, by environmental exposure and by inheritance. In recent years more detail about this has come to the forefront. Now we know that the majority of cancers develop by chance, but this does not mean we should sit back and do nothing. The PAP test with early diagnosis of cancer of the cervix and early treatment has almost eradicated this cancer. HPV vaccinations have added to the armamentarium. Colonoscopies have reduced the incidence of colon cancer, but only through screening at regular intervals. The PSA test has enabled men to check for prostate cancer, and early treatment for this is quite successful. More is known about cancer prevention through supplements and lifestyle.

Nature is cruel and wants to knock us off, as we get older. The only alternative we have is to fight back as follows: reducing environmental causes, increasing preventative steps and going for early treatment, when cancer is diagnosed.

Only Moderate Alcohol Consumption Benefits Your Heart

A new study from England finds that only moderate alcohol consumption benefits your heart. The study was released on March 22, 2017 in Great Britain. 1.937 million people (51% women, 49% men) had participated in this investigation over 6 years. The lead author, Dr. Steven Bell is a genetic epidemiologist. He said that this study was done to clear up some of the confusion from previous studies. He wondered why the control group without alcohol exposure had more cardiac problems than the moderate group. It did make sense though, that the high alcohol group had worse cardiac problems.

But he and researchers from Cambridge University and University College London did this study to get more detail. They wanted to know why the current non-drinking group used as a control was not looked at more carefully. It consisted of a mix of lifelong abstainers; people who drank formerly, but then gave it up. And the other group was those who drink on an occasional basis.

With this in mind the researchers designed their study. They also used also larger numbers to increase the reliability of the study.

Details of English study

The data comes from the Clinical Practice Research Datalink providing anonymous patient records from general practices in England. The patients upon entry into the study had to be older than 30 years, but have no evidence of cardiovascular disease. A total of 1,937,360 patients qualified to be part of the study.

Based on patients’ records and patients recollections people, researchers looked at 5 classes of drinkers:

  • Non-drinkers (14.3%)
  • Former or ex-drinkers (stopped drinking at one point, 3.7%)
  • Occasional drinkers (drinking rarely, 11.9%)
  • Moderate drinkers (drinking within sensible limits, 61.7%)
  • Heavy drinkers (hazardous alcohol use, 8.4%)

The end point of the study researchers concentrated on the frequency of cardiovascular diseases like angina, heart attack, sudden cardiac death, stroke, peripheral arterial disease, abdominal aortic aneurysm and others. I only listed 6 of the 12 cardiovascular diagnoses as otherwise it would get too technical.

More information: Most study participants were non-smokers, their BMI was within normal limits, and they also did not have diabetes.

Findings of the study

There were significant differences among subclasses of alcohol consumption and the development of cardiovascular diseases over 6 years.

  1. The findings were in line with a number of previous similar studies that showed a U-type dose response curve between developing cardiovascular diseases and alcohol consumption. The group of non-drinkers (where former and occasional drinkers were removed) often had a 20% to 56% increased risk of developing cardiovascular disease, while moderate drinkers had no added risk.
  2. On the other hand the heavy drinkers were at risk of developing cardiac arrest (50% increased risk) or heart failure (22% increased risk). A death from a sudden heart attack occurred in heavy drinkers with a risk of 21% increased risk. A former drinker had a 40% increased risk for this, but a non-drinker a risk of 56% increased risk!
  3. A non-drinker had a 32% increased risk of getting a regular heart attack, a former drinker had a 31% increased risk, an occasional drinker 14%, a moderate drinker no added risk, and a heavy drinker had a 12% reduced risk! This seemed to show that drinking alcohol keeps the coronary arteries open and clean. I have had pathology demonstrations with Professor Dr. Adalbert Bohle at Tübingen University during my medical training in 1969. At that time he pointed out how clear and wide open the coronary arteries were in chronic alcoholics. It was not heart disease that killed those patients; they had died from end stage liver cirrhosis, and we saw pathological slides of that.
  4. Heavy drinkers get more ischemic strokes (33% increased risk) and more intracerebral hemorrhages (37% increased risk).
  5. Obstruction of blood vessels in the lower legs (peripheral arterial disease) is common with heavy drinkers (35% increased risk) and even former drinkers (32% increased risk). Non-drinkers have a 22% increased risk while moderate drinkers have a 0% risk (no increased risk).
  6. There was no association between heavy drinking and aortic aneurysm. On the other hand, non-drinkers (32% increased risk) and former drinkers (23% increased risk) showed an increased risk of aortic aneurysm formation.

Other effects of alcohol consumption

The study above did not take into consideration that alcohol consumption has many other consequences beside cardiovascular effects. One for instance is the effect on the brain and the increase of serious car accidents. Another effect is the causation of cancer.

The American Cancer Society clearly states that alcohol consumption has been causatively associated with the following cancers.

  • Cancer of the mouth
  • Cancer of the pharynx (throat)
  • Cancer of the larynx (voice box)
  • Cancer of the esophagus
  • Cancer of the liver
  • Cancer of the breast
  • Cancer of the colon
  • Alcohol also plays a role with cancer of the pancreas

Many studies have shown a dose-response curve between alcohol consumed and the development of these cancers. In other words there is never a safe low dose, below which no cancer would be caused over time.

These authors conducted a metaanalysis of 16 prospective cohort studies including 6,300 patients. It showed that alcohol caused cancer of the colon and rectum. High intake of alcohol showed a 50% increased risk of causing colon cancer. With regard to rectal cancer the risk was 63% higher. In both cases the highest alcohol intake was compared to the lowest category of alcohol intake.

These authors concluded their discussion by pointing out that 6% of the worldwide cancer deaths are attributed to alcohol intake. They also stated that colorectal cancer risk increased by 50% in the heaviest alcohol users. Among the group of heavy drinkers the cancer death rate would likely be 9%. There would a reduction of mortality from cardiovascular disease by one third in middle and old age. The end result would be 6% mortality again; essentially there is no change.

No matter how you try to solve this equation, there is a risk of cancer deaths from exposure to alcohol. There is also a risk that heavy drinking can cause significant cardiovascular diseases mentioned.

Conclusion

Everything we do in life has consequences. With regard to drinking you know that accidents are more common in drinkers; with prolonged exposure to higher alcohol consumption you can get dementia. Moderate amounts appear to have significant protection from heart disease, but the risk for several cancers is not negligible. This point was not mentioned in the study I discussed in the beginning of my blog. In the latter part I included some data about cancer risks from alcohol consumption.

The paradox remains that non-consumption of alcohol is associated with a significant cardiovascular risk because of a U-shape dose response curve. Moderate alcohol use is associated with the lowest cardiovascular risk. The question is whether we can balance moderate drinking with staying in the low cancer risk area. The recommendation of 1 glass of wine for women and 2 glasses of wine for men has been confirmed by the above study. This is considered a healthy preventative dose with respect to cardiovascular risk. It is the official recommendation for cardiovascular disease prevention. The cancer literature clearly states that there is a small cancer risk from moderate alcohol intake. This is particularly true for the 8 cancers discussed.

Dr James Nicholls, the director of research and policy development at Alcohol Research UK had this to say. He pointed to the fact that there are other ways to prevent cardiovascular disease. For those who do not drink at present it would not make sense to take up drinking. You can strengthen your heart by starting a Mediterranean diet and starting to exercise regularly. The beneficial substance for your heart in red wine is known as resveratrol that can be taken as a supplement. Resveratrol has no side effects and does not have the cancer risk of an alcoholic drink. Dr. Nicholls added, “If you drink within the existing guidelines it is unlikely that alcohol will either lengthen or shorten your life.” It is really up to every individual to balance the wine glass with personal health!

What Foods Lower Insulin Resistance?

When people get diabetes or prediabetes, what foods lower insulin resistance? You may have heard that eating too many carbs and gaining weight can cause high insulin values. This causes the body’s insulin receptors to become sluggish, a condition called insulin resistance. Continuing to eat too many refined carbs leads to a critical point. You can suddenly run out of enough insulin and would develop type 2 diabetes at this time.

So, what foods lower insulin resistance?

Low glycemic food

Insulin resistance and type 2 diabetes occur because people do not pay attention to the glycemic load of the food they choose. Many people eat bread, pasta and starchy vegetables like potatoes. They also eat excessive sugary sweets, such as cupcakes, ice cream, or chocolate bars. All the pancreas can do is keeping blood sugar stable by overproducing insulin. But you can assist your pancreas to not overwork itself.

Leave the high glycemic index foods alone. Instead eat low glycemic foods like non-starchy vegetables (peppers, broccoli), lean meats, fish and nuts. Add high-fiber foods like beans and some whole grains. Eat foods rich in omega-3 fatty acids like salmon. Have a dessert with berries that are rich in antioxidants. Blueberries, strawberries, raspberries and black berries are all low glycemic foods, rich in vitamin C and antioxidants. They are “nature’s candy”.

Research on insulin resistance

In a study from Singapore differences of insulin sensitivity were found between lean Asian Indians and Chinese and Malays, living in Singapore. The Asian Indians had less insulin sensitivity, which means they had higher insulin resistance. This is presumed to be due to a genetic variant of insulin sensitivity.

Another lengthy publication investigated the connection between metabolic syndrome and insulin resistance. In addition it examined the connection of heart attacks and strokes to wrong diets. It also pointed out that diabetes and cardiovascular disease could be reduced significantly. How can this be achieved? By adopting a healthy diet that also leads to weight loss.

Diets in the US and in the Western world have major shortfalls, due to the fact that people consume not enough vegetables, fruit and whole grains. Instead we see a higher intake of red and processed meat. In addition there was higher intake of sugar-sweetened foods and beverages. Refined grains and flour products are another unhealthy food source. In the US and other westernized countries we see an overconsumption of sodium and saturated fat.The key to a healthy diet was adopting a Mediterranean diet. A study was described where a group of patients with metabolic syndrome were encourage to consume whole grains, vegetables, fruits, nuts, and olive oil. The control group simply followed a “prudent” diet. Two years later the group on the Mediterranean diet was found to have the following results: they had a higher intake of monounsaturated fat (olive oil) and polyunsaturated fat (fish oil) and fiber. Their omega-6 to omega-3 ratio had decreased. The high-sensitivity C-reactive protein, a general measure for inflammation, had decreased. Other inflammatory kinins like interleukins had also decreased. The insulin sensitivity endothelial function score showed improvement. The important part overall was that the Mediterranean diet prevented the metabolic syndrome compared to the “prudent” control diet.

In 2013 a study from Spain was looking for positive effects when supplementing with olive oil or nuts. A Mediterranean diet with extra olive oil or extra nuts reduced the risk of heart attacks in a high-risk group compared to controls. The study included 7447 persons and these were the results after 4.8 years: the Mediterranean diet group that used more olive oil had 28% fewer cardiovascular events compared to the control group. The Mediterranean diet group with nuts had 30% less events. Heart attacks, strokes or death from cardiovascular disease were these “events”!

What foods are unhealthy?

In order to be able to avoid unhealthy foods it is important to identify what harms us. Foods to avoid are listed in this link. Sweetened beverages, fountain drinks, sodas and fruit juices are loaded with sugar. They will cause an insulin response and on the long-term insulin resistance. Avoid starchy vegetables, such as potatoes, pumpkin, corn, and yams. Also avoid processed snacks and boxed foods. Starchy foods are broken down into sugar, which stimulates insulin release again. Your no-food list continues with excessive sugary sweets, such as cupcakes, ice cream and chocolate bars. White bread, rice, pasta, and flour are also starchy, and the body breaks down starch into sugar and stimulates insulin production.

Some saturated fats are acceptable, but hydrogenated fat must be avoided altogether.

Epigenetic factors regarding insulin resistance

A recent publication on March 14, 2017 investigated the effect of exercise on insulin sensitivity in a mouse model where the mother mouse was obese.

Pregnant, obese mice were insulin resistant and the offspring came down with diabetes. But when the pregnant mice were exercised, the insulin sensitivity came back to normal. In addition the offspring were not diabetic. This effect was not due to genetic factors. Instead the authors believe it was due to epigenetic factors, in this case treating insulin resistance with exercise. When the pregnant mother turns insulin sensitive, the offspring is programmed to regulate their blood sugar metabolism normally.

An April 2017 study from Korea investigated the effects of healthy nutrition on patients with metabolic syndrome and insulin resistance. They noted that avoiding unhealthy foods could normalize markers of disease.

The authors discuss how nutritional factors can contribute to inheritance of epigenetic markers in the next generation. They also showed how dietary bioactive compounds could modify epigenetic factors. Taking dietary components that regulate epigenetic factors contribute significantly to health. The authors concluded that a healthy diet could prevent pathological processes that otherwise would cause metabolic disease.

What Foods Lower Insulin Resistance?

What Foods Lower Insulin Resistance?

Conclusion

It is interesting to note that insulin resistance can be reversed into insulin sensitivity by eating healthy foods. Research papers are now describing how a healthy diet of the mother can affect her offspring positively. These effects are due to epigenetic factors, as genetic factors have not changed.

We are already hearing that diseases like heart attacks, high blood pressure, strokes, diabetes and others can largely be prevented by a proper diet. The key is to avoid high glycemic foods and eat low glycemic foods instead. It is not complicated. Eat non-starchy vegetables (leafy greens, peppers, broccoli), lean meats, fish and nuts. Add high-fiber foods like beans and some whole grains. Eat foods rich in omega-3 fatty acids like salmon. The end result is that insulin resistance disappears and metabolic processes return to normal. This was what Hippocrates had in mind when he stated “Let food be thy medicine and medicine be thy food.”
