What lowers LDL cholesterol?

Many times we hear terms like LDL and HDL cholesterol , but what lowers LDL cholesterol? We have to go back to a time when the ongoing Framingham Heart Study wanted to find out what caused a heart attack or a stroke. In the 1960’s scientists found out that cigarette smoking increased heart attack risk and also blood cholesterol. Then in the 1980’s the news came out that HDL (high density lipoproteins) reduced the risk of heart disease. Eventually several research institutions agreed that LDL (low density lipoproteins) was the culprit for causing plaque deposits in arteries. This caused heart attacks and strokes. LDL is often referred to as the “bad” cholesterol.

Clarification of HDL and LDL cholesterol

Recently a review article asked the question: “What is the difference between HDL and LDL cholesterol?”

Below I will review what LDL and HDL cholesterol do in our system. I will also mention normal values for blood tests. This will help you to understand your own blood test results. Then I will review what you can do to lower LDL cholesterol and to increase HDL cholesterol.

The function of LDL and HDL cholesterol

Total cholesterol in the blood contains LDL cholesterol, small dense LDL cholesterol and HDL cholesterol. The small dense LDL cholesterol is more dangerous than LDL cholesterol. It infiltrates the lining of the arterial walls aggressively. A normal LDL level is less than 100 mg/dL. When triglycerides, another form of lipid is high in the blood, LDL cholesterol forms a lot more small dense LDL cholesterol. This is the case in diabetics or in obese people. It is the reason why they are very vulnerable to develop heart attacks and strokes. The optimal range for triglycerides is less than 80 mg/dL.

HDL cholesterol is protective from hardening of the arteries and protects you from heart attacks or strokes. HDL dissolves LDL cholesterol, brings it to the liver, and the liver excretes it into bile. You want to have more than 60 mg/dL of HDL cholesterol in your blood.

Cholesterol math

The total cholesterol conventionally is calculated like this:

LDL cholesterol + HDL cholesterol + (triglyceride/5) = Total cholesterol

You see that the small dense LDL is not part of it here, but high triglyceride levels would increase the total cholesterol value as the inclusion of 20% of triglycerides in this equation compensates for this.

There is also a ratio of total cholesterol to HDL cholesterol that is important. This ratio should be below 3.4 for both women and men. This is also known as the ½ average risk for a heart attack or stroke. If your value is equal to that or below, you are in a very low risk category to get a heart attack or stroke.

Now I will deal with the question: what lowers LDL cholesterol?

What lowers LDL cholesterol?

Now we need to review what can be done to lower an LDL cholesterol which is too high. Don’t tell me that you want to take one of the statin drugs. These drugs have serious side effects and are only indicated for the most serious cases of high cholesterol values.

Most common measures to reduce LDL cholesterol

  • Cut out red meat

    First of all, cutting out red meat (like beef, pork and sausages) to an absolute minimum, for instance once per week or less is important. The reason is that these meats have more cholesterol in them and also more saturated fats than any other foods. Compare that to poultry, fish and vegetables like beans, which are healthy food sources.

  • Eliminate trans fats

    Furthermore, we need to eliminate trans fats as they are causing heart attacks. There is an important difference between ruminant trans fats and artificial trans fats. Ruminant trans fats have been part of the human diet for millennia like milk fat and fat from cows that are on pasture or lamb. Milk products for instance contain fat with 2-5% natural trans fats. 3-9 % of the fat in beef and lamb consists of natural trans fats. Studies have shown that the body is able to handle these natural trans fats, and heart attacks are not more frequent in people eating moderate amounts of these products including butter from cows that graze on pasture.

  • Artificial trans fats

    Quite the opposite is true for artificial trans fats in margarine that comes from vegetable oil. Avoid bakery items like sweet pieces or muffins and other products that contain hydrogenated oils. Read labels! Use olive oil or coconut oil, but avoid vegetable oils like corn oil, safflower oil or grape seed oil to get away from trans fats and unstable oils that turn rancid. Rancid oils contain free radicals that oxidize LDL cholesterol and attack the lining of your arteries through small dense LDL cholesterol.

  • Cut out sugar and starchy foods

    Another important item is to cut out sugar and starchy foods because these will raise your LDL cholesterol and triglycerides, which also leads to hardening of your arteries. Starchy foods are broken down by pancreatic juices into sugar, which enters your blood stream, causing an outpouring of insulin from the pancreas. When the short-term storage of sugar as glycogen is exhausted in muscle and liver tissue, the liver has to process any surplus of sugar that is still there. The end results are triglycerides and LDL cholesterol. Unfortunately the protective HDL cholesterol does not reach higher levels, when the LDL cholesterol is increased. A persistent diet of high-refined carbs will increase the risk for heart attacks and strokes. It follows from this that we are all better off cutting out sugar and starchy foods from our food intake as it will reduce LDL cholesterol and small dense LDL cholesterol.

  • Increase your soluble fiber intake

    Increase your soluble fiber intake by eating vegetables, oats and oat bran, lentils, fruits and beans. Why does this decrease LDL cholesterol? The liver tries to eliminate too much cholesterol by binding it to bile salts and excreting it into your small bowel. But the last part of the small bowel reabsorbs some of these bile salts, and from there they return to the liver. This is called the enterohepatic pathway of bile salts. Soluble fiber intake binds those bile salts and prevents re-absorption in the enterohepatic pathway, eliminating cholesterol safely in stool. Clinical trials have also shown that soluble fiber from psyllium, pectin, beta-glucans and others reduce LDL cholesterol by binding bile salts in the gut (interrupting the enterohepatic pathway).

  • Plant sterols and fiber supplements

    Plant sterols (usually sold as sterol esters) are recognized by the FDA as reducing the risk of coronary heart disease, if taken in high enough amounts (2.4 grams of sterol esters per day). There are other useful supplements like artichoke extract, pomegranate, soy protein, Indian gooseberry (Amla), garlic and pantethine (vitamin B5) that are beneficial in terms of prevention of heart attacks and strokes. It would be too lengthy to get into more details here.

  • Take a whey protein supplement

    There are two major milk proteins, whey and casein. Only whey protein binds to total and LDL cholesterol, lowering both. It is available in health food stores. Follow the package insert of the whey product for dosing.

  • Increase your omega-3 fatty acid intake

    Omega-3 fats naturally present in fish oils and nuts. They increase the amount of circulating HDL cholesterol, which binds the bad LDL cholesterol. Go ahead and eat salmon, herring and mackerel as well as walnuts, ground flaxseeds and almonds. You can also take molecularly distilled (or pharmaceutically pure) EPA/DHA supplements. This pure form of fish oil is free of mercury and other heavy metals. EPA stands for eicosapentaenoic acid or omega-3 fatty acid. DHA is the acronym for docosahexaenoic acid, an important supplement for the brain. Tests have shown that fish oil supplements at a dosage of 3.35 grams per day of EPA plus DHA reduce triglycerides by up to 40%, equally to Lipitor, but without the statin side effects. The end result: your total cholesterol/HDL ratio decreases, as does the risk for heart attacks and strokes. Here is a review of other oils in your diet.

Measures that will increase HDL cholesterol 

  • Eat foods with anthocyanin

    In a 24-week study with diabetic people HDL levels rose by 19% when food was eaten that was rich in anthocyanin. This consisted of eggplant, purple corn, red cabbage, blueberries and blackberries. The advantage of raising the HDL cholesterol level is that the total cholesterol to HDL ratio decreases, which lowers the risk for heart attacks and strokes.

  • Exercising regularly

    Exercising will increase your HDL cholesterol, which again decreases the ratio of total cholesterol to HDL cholesterol. This number should be between 1 and 3.5, the lower, the better.

  • Take a supplement called Ubiquinol, or Co-Q-10

    Adults above the age of 60 need 400 mg once daily, younger people need between 200 mg and 300 mg daily. Co-Q-10 prevents oxidation of LDL cholesterol, which would aggressively attack the arterial walls causing hardening of the arteries. What causes oxidation of cholesterol? The answer is clear: fried foods like french fries or deep fried chicken will lead to oxidation; other culprits are margarine, commercially baked goods and cigarette smoking.

  • Calcium and vitamin D3

    Recently a study on postmenopausal and overweight or obese women found that supplements of calcium combined with vitamin D3 lowered cholesterol.

  • Polyphenols

    Flavonoids are the largest group among the polyphenols in such common foods as vegetables, fruits, tea, coffee, chocolate and wine. Over 130 studies on humans have shown improvement of the lining of the arteries (endothelial functioning) and lowering of blood pressure. Polyphenol consumption has a connection to a lower risk of mortality from heart attacks. Eat a Mediterranean type diet or a DASH diet, and you will automatically get enough polyphenols with your food. However, resveratrol, the powerful red wine polyphenol, warrants a separate daily supplementation as it prevents LDL oxidation in humans (Ref.1). Take about 250 mg of resveratrol daily.

  • Niacin/ nicotinic acid

    This supplement comes as “flush-free niacin” and also as extended release niacin. It can raise the beneficial HDL cholesterol by 30 to 35% when patients take higher doses of 2.25 grams per day. In a metaanalysis of 7 studies researchers found a significant reduction of heart attacks and transient ischemic attacks. These are precursor syndromes before developing a stroke. Niacin can change the small particle LDL into a large particle size LDL, which is less dangerous. Niacin also reduces oxidation of LDL, which stops the atherosclerotic process. For a healthy person 500 mg per day of flush-free niacin is adequate.

  • Curcumin

    This is a powerful heart and brain protector combining three different mechanisms in one. It is reducing oxidative stress. But it is  also an anti-inflammatory. In addition it counters the process that threatens to destroy the lining of the arteries. One study on healthy volunteers showed reduction of 33% in lipid oxidation, a 12% reduction of total cholesterol and an increase of 29% of the protective HDL cholesterol when patients took 500 mg of curcumin for only 7 days (Ref.1). This is the daily dose I would recommend for prevention of heart attacks and strokes.

  • Vitamin E (tocopherols)

    This fat-soluble vitamin is an antioxidant and in the past health practitioners knew about its use as being heart supportive. Strangely enough some conservative physicians bad-mouthed this vitamin. In the meantime health practitioners have returned to using the vitamin. It turns out that there are 8 different types of tocopherols, with the alpha tocopherol being the best-known, but you also want to be sure that you are getting gamma tocopherol with your balanced vitamin E supplement every day. It remains the one that is a powerful anti-inflammatory. Simply ask staff at your health food store for a vitamin E supplement with gamma tocopherol in it. Take 400 IU per day (of the mix).

What lowers LDL cholesterol?

Conclusion

Over the years cardiovascular researchers have accumulated knowledge about supplements that will reduce LDL cholesterol or increase HDL cholesterol. It has practical value: you can look at your own lab results and choose what fits your situation best. You should always make these decisions together with your health care provider. None of the methods reviewed here have any serious side effects. On the other hand statins, as I have reviewed in the link provided, do have significant side effects. Keep in mind that cholesterol is a normal body component that our body needs to make human cell walls. But we do not need to smoke (stopping it lowers LDL cholesterol). We need regular exercise (increases HDL cholesterol). Keep your cholesterol and triglyceride values within the normal ranges that I listed and as a result you will do well in terms of preventing heart attacks and strokes!

Lower Cholesterol

When your cholesterol is high, what can you do to lower cholesterol? First, there is the bad cholesterol, called LDL cholesterol that should not be too high. Furthermore, there is the good cholesterol, called HDL cholesterol that you want to be to higher to protect you from hardening of the arteries. LDL cholesterol finds its way into plaques of arteries, and later calcification occurs. HDL cholesterol does the opposite; it dissolves LDL cholesterol and brings it to the liver.

Food contributes only to a small portion to the increases of your LDL cholesterol (the bad cholesterol) in the blood. The minor part of the body’s cholesterol stems directly the refined carbs and trans fats from your diet. Here are a number of steps that will protect your heart from LDL cholesterol.

1. Cut out red meat

Cutting out red meat (like beef, pork and sausages) to an absolute minimum, for instance once per week or less is important. The reason is that these meats have more cholesterol in them and also more saturated fats than any other foods.

Lower Cholesterol

Conclusion

There is a lot you can do to control your cholesterol level by changing your diet, shedding some pounds, exercising and quitting smoking. All this will contribute to lower cholesterol. This will have a beneficial, long-term effect regarding prevention of heart attacks and strokes. In addition there are specific supplements and vitamins, which prevent heart attacks and strokes as well. With these measures the majority of people with high LDL cholesterol can change their cholesterol levels without taking statins. Statins have serious side effects like Alzheimer’s disease and a painful muscle condition called rhabdomyolysis. None of the other measures described here have any such side effect. Even if you chose to only concentrate on a few of these 14 points to lower cholesterol there will be significant improvements in your LDL and HDL cholesterol levels, when you ask your doctor to order these blood tests.

Vitamin K For Bones And Arteries

Vitamin K for bones and arteries is gaining a lot of attention as a valuable supplement. Most of all in the blood vessels, but in addition in the heart, lungs and kidneys the matrix GLA protein is a key substance. Vitamin K2 is crucial for removing calcium from these organs, as matrix GLA protein is carboxylated. Carboxylation of the GLA protein functions much as a broom. This removes all superfluous calcium from blood vessels and organ tissues. If there is a lack of vitamin K2 intake, matrix GLA protein is uncarboxylated, which as a result invites vascular calcification. Essentially vitamin K2 has emerged as an important player in the regulation of bone conditions like osteoporosis, but also in the prevention of hardening of arteries. Vitamin K2 removes calcium from blood vessels and deposits calcium in bone preventing osteoporosis. I will review some key publications, which support this.

Arterial stiffness study in postmenopausal women

Aging blood vessels become stiff from calcification. By removing calcium it seems like the arterial wall becomes more flexible again. Dr. Knapen and colleagues from Maastricht University, The Netherlands followed 244 healthy, postmenopausal women for 3 years in this double blind, placebo-controlled 2015 study.

120 women received 180 micrograms of vitamin K2 (as MK-7) once daily. 124 women received placebo pills. Next researchers checked arterial stiffness through two types of tests. First of all, carotid intima-media thickness was evaluated by echo tracking. In addition aortic stiffness was tested by carotid-femoral and carotid-radial pulse wave velocity. After 3 years there was a significant reduction of uncarboxylated matrix GLA by 50%. This was missing in the placebo group. All of the markers for arterial stiffness showed a reversal improving flexibility above the median. This shows that hardening of arteries in postmenopausal women is reversible with the help of vitamin K2.

Bone metabolism study in Japanese men and women

This 2015 Japanese study investigated what the minimum amount of necessary vitamin K2 would be to improve osteocalcin carboxylation.

First of all, study 1 examined the effect of 0, 50, 100, or 200 micrograms of vitamin K2 (=menaquinone-7) daily. A group of 60 postmenopausal women received vitamin K2 for 4 weeks. Only the 200 microgram per day dosage showed an effect of carboxylating osteocalcin.

Second part of study

Furthermore, study 2 consisted of 120 men and women. Measurements involved the ratio between carboxylated and uncarboxylated osteocalcin to demonstrate the effect of vitamin K2. As a result of study 1 only a placebo group, a 100-microgram and a 200-microgram daily vitamin K2 group was part of the investigation. Both, the 100 microgram and the 200 microgram doses, reduced the circulating uncarboxylated osteocalcin fraction. Hence they concluded that vitamin K-2 effectively keeps the calcium in the bones and prevents osteoporosis. The investigators recommended taking more than 100 micrograms of vitamin K-2 per day to improve osteocalcin carboxylation.

You can find more detail regarding the interaction of calcium, vitamin D3 and vitamin K2 in this link.

Trabecular bone structure preserved in postmenopausal women

148 postmenopausal women were participating for 12 months in a randomized, placebo-controlled, double-blinded clinical trial. All these women had osteopenia. All of them received supplements with calcium and vitamin D3. In addition they received 375 micrograms of vitamin K2 or placebo pills. Examination involved tests for bone mineral density with dual X-ray absorptiometry (DXA). Furthermore a high-resolution CAT scanner determined the microarchitecture of the tibia bone.

After 3 months the uncarboxylated osteocalcin decreased by 65.6% rather than the placebo group of only 6.4% decrease. The trabecular number, spacing and thickness in the tibial bone were unchanged in the vitamin K2 group. In contrast to that there was a clear deterioration of the bone structure in the placebo group.

Summary of trabecular bone study

The bone density studies showed no detectable difference between the groups. The deterioration of the trabecular microstructure in the placebo group was consistent with expected age-related changes. On the other hand, the vitamin K2 group clearly demonstrated preservation of the trabecular bone structure in the tibial bone.

Vitamin K2 helps to eliminate toxic effects of calcium

This 2015 publication from Krakow, Poland explains rather well how vitamin K2 is important to reduce calcium from blood vessels.

At the same time the article points out that vitamin K2 is important for depositing calcium into bones to prevent osteoporosis. The removal of calcium from blood vessels occurs by carboxylation of matrix GLA protein. This functions like a shield to protect blood vessels from calcium entering into the arterial wall. This way the arteries are probably safe from calcification, and hardening of the arteries cannot take place. On the other hand calcium is binding to the bone. As explained above the hormone osteocalcin is responsible for this.Vitamin K2 is the main player in the process of carboxylization. As a result vitamin K2 makes it happen that calcium travels into the bone, where it belongs.

Rotterdam Study: reduced heart attack rates from vitamin K2

4807 subjects from the Rotterdam Study in the Netherlands were part of a study for considerable time (about 10 years) with no sign of any heart attack in the beginning.

The investigators were interested to correlate the effects of various doses of vitamin K1 and K2. How would this impact the frequency of heart disease, hardening of the aorta and all-cause mortality? Researchers adjusted the data for smoking, age, gender, body mass index, diabetes, education, and dietary factors. Next they compared the middle and upper tertile groups of vitamin K1 and K2 to the lower tertile of vitamin K1 and K2.

Results of Rotterdam Study

Most noteworthy, the relative risk for coronary heart disease was lower for the middle and upper tertile of the vitamin K2 group. They found that the middle tertile vitamin K2 intake lowered heart attacks by 27%. It was especially relevant that the upper tertile of vitamin K2 intake lowered heart attack rates by 57%.

In addition, all-cause mortality also showed a reduction for the middle tertile of vitamin K2 by 9% and for the upper tertile by 26%. Finally, severe aortic calcification was 29% less for the middle tertile of vitamin K2 and even 52% less for the upper tertile. Intake of vitamin K1 (=phylloquinone had no impact on any of the outcomes. The investigators concluded that adequate intake of vitamin K2 (=menaquinone) was crucial for anybody’s health. First of all, vitamin K2 lowers heart attack rates, in addition it reduces hardening of the arteries including the aorta and finally, it lowers all-cause mortality.

Vitamin K For Bones And Arteries

Vitamin K For Bones And Arteries

Conclusion

This review shows evidence that vitamin K2 supplementation is important for the prevention of osteoporosis and heart disease. It prevents heart attacks and hardening of arteries, including the aorta. The dosage necessary to achieve this is only 200 micrograms of vitamin K2 per day. However, in Japan higher doses like 375 micrograms per day are the common protocol for prevention of osteoporosis.

Effect of vitamin K2 for bones and arteries

How does vitamin K2 work? In the blood vessels vitamin K2 carboxylates the matrix GLA protein. Essentially this keeps calcium out of the arterial wall and prevents hardening of the arteries. This reduces heart attacks and significantly lowers mortality from heart attacks as well. The second effect of vitamin K2 is on bones. Vitamin K2 prevents osteoporosis to a large extent. It does so by binding calcium to the bone. The hormone osteocalcin, which is carboxylated by vitamin K2 effectively moves calcium from the bloodstream into the bone and keeps it in the bone. If you take vitamin K for bones and arteries, you double the benefit from this simple vitamin. Remember to take 200 micrograms of vitamin K2 daily. The benefits are certainly remarkable!

New Treatments For Premenstrual Syndrome

Dr. Pamela W. Smith gave a talk about new treatments for premenstrual syndrome (PMS). She presented this talk on Dec. 11 at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended. The original title was “New Treatment Modalities for PMS”.

Signs and symptoms of PMS

Dr. Smith discussed signs and symptoms of PMS first. She showed 9 slides where she listed all of the symptoms of PMS that commonly occur.

Symptoms are varied; they can mimic various psychological problems like anxiety, depression, panic attacks and more. But physical symptoms like abdominal bloating, acne, back aches, and asthmatic attacks are also common. There are a myriad of more symptoms of PMS: constipation, cramps, clumsiness, dizziness, drowsiness, decreased sex drive, facial swelling, forgetfulness, fatigue, headaches, a herpes-like outbreak, hot flashes, sensitivity to light and noise, insomnia, joint pains, mood swings, palpitations, restlessness, poor memory, sore throat, tearfulness, vomiting and weight gain.

What do we know about PMS?

  1. There is no definitive test that would help in the diagnosis of PMS. But we do know that there is a hormone dysfunction that leads to a monthly recurrence of symptoms during the two weeks prior to the woman’s menstruation. When her period begins or shortly after all of these symptoms disappear.
  2. PMS is very common; 70to 90% of women have a certain degree of PMS. In 20 to 40% of women symptoms are severe. Many researchers have shown that there is a problem in the feedback loop between the pituitary gland and the ovaries. This leads to a decrease of progesterone production in the ovaries. The result is an overabundance of estrogen, which is called estrogen dominance.
  3. But things can get complicated when other hormone changes occur. A woman may also turn hypothyroid. When she gets closer to menopause estrogen deficiency may also develop. Electrolyte disturbances can occur from high estrogen levels causing excessive aldosterone levels. This would lead to high sodium and low potassium blood levels. The end result may be an activation of the renin-angiotensin system, which could cause high blood pressure.
  4. Neurotransmitters are often disbalanced. When serotonin is low in the brain, depression can develop. Noradrenalin deficiency leads to a lack of focus, energy and memory.
  5. Hypoglycemia is also common among women with PMS. This may be due to cravings for sweets and consumption of starchy foods. Women who crave sweets may also consume caffeine excessively. But caffeine increases prostaglandin production in the body. This leads to breast tenderness, abdominal cramping, arthritis and back pains.
  6. A partial hysterectomy can cause PMS in a woman who never before had symptoms of PMS. The current school of thought is that blood supply to the ovaries after a hysterectomy has decreased, and this could be the reason for the onset of PMS.
  7. The birth control pill can bring on PMS due to the progestin component in it.
  8. Tubal ligations can also be a cause: 37% of women who had tubal ligations develop PMS. The reason is a change in hormone production. In these women estrogen is produced to a higher degree than progesterone is.
  9. Pregnancies, miscarriages and abortions can also bring on PMS.

Lab tests for women with PMS

Although there is no single test that would be able to diagnoses PMS, a variety of abnormal tests are often abnormal in association with PMS. Frequently there is deficiency for vitamin A, B6, E, magnesium, potassium, zinc and trace minerals. Calcium can be too high or too low, but blood tests will reveal that.

Four PMS types

Dr. Smith said that PMS has been divided into 4 subcategories depending on the main symptoms.

  • PMS A: Anxiety
  • PMS C: Carbohydrate craving
  • PMS D: Depression
  • PMS H: Hyperhydration

PMS A is associated with estrogen excess and progesterone deficiency. There is a diminished stress response in the hypothalamus/pituitary/adrenals axis. Symptoms are mainly anxiety, irritability, insomnia and emotional lability.

PMS C is associated with sugar craving, hypoglycemia, headaches, heart palpitations and spontaneous sweating.

PMS D is leading to increased neurotransmitter degradation. Symptoms consist of depression, crying, despair, feeling hopeless, fatigue, low libido, apathy and insomnia.

PMS H is caused by increased aldosterone activity triggered by estrogen surplus in the late luteal phase. Symptoms are weight gain, swelling of hands and feet, a feeling of bloating, breast tenderness or engorged breasts. Women will find that their clothes simply fit tighter.

Migraine headaches in PMS

Some women with PMS are plagued by migraine headaches. It may have started in puberty or after taking birth control pills for contraception. Sometimes the onset is after a pregnancy, miscarriage or abortion. When PMS develops and a woman has migraines, they usually occur around the same time in her menstrual cycle. With pregnancy the migraines disappear in the last trimester when progesterone hormone production from the placenta is the highest.

Hormonally related headaches can occur for 4 main reasons.

  1. When estrogen and progesterone are on the rise around the time of ovulation
  2. When a woman has hypoglycemia (due to hyperinsulinemia)
  3. When estrogen levels are changing
  4. When there is estrogen dominance

Treatment for PMS

Dr. Smith explained in detail the various treatment modalities for PMS. Treatment has to be personalized according to what type of PMS the doctor thinks that the patient is suffering of.

Dietary factors

In the beginning it is important to pay attention to the diet. Studies have shown that PMS patients tend to eat too many carbs and too much refined sugar compared to patients without PMS. PMS patients also eat too many dairy products and too much sodium. In addition PMS patients are deficient in iron, manganese and zinc. A good start is a Mediterranean diet, which is at the same time anti-inflammatory.

The recommendations is to eat 6 small meals a day. Avoid caffeine and alcohol. They are antagonists to the B complex vitamins. By avoiding sugar, you also avoid fluid accumulation and magnesium deficiency. A low fat, high-complex carb diet helps reduce breast tenderness. Reducing fat and increasing fiber in the diet decreases estrogen levels in the blood. These steps help PMS symptoms.

Nutritional supplements

Magnesium, vitamin B6, A, D3, E, L-tryptophan, calcium, zinc, fish oil (EPA/DHA) and evening primrose oil are the main supplements recommended for PMS patients. Your healthcare provider can advise you what you should take and what dosage.

Exercise

Regular exercise has very beneficial effects on reducing many symptoms of PMS. Even as little as 8 weeks of exercise -as was done in this study- had a significant effect. Exercise elevates endorphin levels, improves blood sugar stability, decreases norepinephrine and epinephrine in the brain and helps to decrease estrogen levels. This will control blood sugar levels, reduce anxiety, reduce estrogen-related symptoms and increase satisfaction.

Thyroid medication

Many women with PMS have borderline hypothyroidism or are overtly hypothyroid. In these cases the patient should receive small amounts of thyroid hormones.

Progesterone

Progesterone is the one hormone that is found persistently lacking in most PMS patients. The best test for this is a saliva hormone test, because this reflects the tissue levels. Blood levels test too low and are useless. Bioidentical progesterone cream is applied transdermally (through the skin) from day 14 to 25 of each menstrual cycle. Micronized progesterone pills are also bioidentical and could be used instead of the cream.

Botanicals

There are a number of home remedies, which are heavily promoted on the Internet. They may, however, not be as effective as advertised.

  1. Black Cohosh is said to balance estrogen and is anti-spasmodic.
  2. Chasteberry decreases LH and prolactin. It raises progesterone, acts as a diuretic and binds opiate receptors. This reduces PMS related aches and pains.
  3. St. John’s Wort helps these symptoms: anxiety, depression, mood swings, feeling out of control and pain.
  4. Ginkgo biloba is a mild blood thinner. Women who are on blood thinners should not use it! It improves depressive symptoms and mood, has anti-inflammatory effects and helps with anxiety control.
  5. Saffron: In a clinical trial the Saffron group did significantly better in PMS symptom control than the placebo group.  Saffron is rich in magnesium, vitamin B6, iron and other nutrients that are missing in PMS patients, which explains the effectiveness of this botanical.
  6. Other botanicals: Other botanicals are Lavender, Motherwort, and Dandelion.

Candidiasis

Due to prolonged exposure to high sugar and refined carb intake many women with PMS suffer from candidiasis (chronic yeast infection). Anti-Candida programs help to eradicate Candida overgrowth, which often improves several PMS symptoms.

Mind/body therapy

Cognitive-behavioral therapy helps for depression and anxiety. Hypnotherapy, yoga and biofeedback therapy are also useful methods.

Conclusion

At the present time there is a better understanding of PMS than in the past. Progesterone deficiency and other hormone weaknesses seem to be at the center of this condition. But vitamin and mineral deficiencies also play a role. The healthcare provider should order some baseline blood tests and hormone tests for the patient, including a saliva progesterone level.

Treatment consists of a combination of steps taken simultaneously. The dietary approach comes first: a Mediterranean diet will be beneficial. Next add nutritional supplements. Regular exercise is essential. Finally bio-identical hormone replacement of the missing hormones is necessary.

If there is an underlying chronic candidiasis infection, it needs treatment. The choice of drug would be nystatin. Some botanicals may be helpful, as discussed. When anxiety and depression are important parts of the PMS symptoms, mind/body therapy (such as cognitive therapy etc.) may also be helpful.

The key with PMS treatment is to not give up, but to re-evaluate the condition, if the initial attempt does not bring full relief. By not giving up and using all modalities of treatment the patient will be able to get rid of the condition, eliminate the symptoms of PMS and achieve well being.

Breast Cancer Risks

Dr. David Zava, PhD gave a talk on breast cancer risks. 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 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 they are not overdosed and they are balanced. 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 leaving away much of the highly technical detail that was presented as this would dilute the message of this blog. I will include a few links for those who are inclined 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, where in the past progesterone was made. This creates a disbalance where estrogen is dominating; it is called “estrogen dominance”.

This is a dangerous hormone disbalance, because the breast ducts are stimulated to grow and 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 where progesterone was replaced through a skin progesterone cream (percutaneous bioidentical progesterone cream). Plasma and breast tissue concentration of progesterone were measured in 40 premenstrual women. They had been diagnosed with breast lumps and were scheduled for surgery. One group was treated with progesterone cream for 10 to 13 days; the other group was the placebo group. At the time of surgery the plasma (blood) values were unchanged, but progesterone levels in breast tissue were elevated more than 100-fold over the values from the placebo group who had been treated with 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 was shown to increase the number of proliferating epithelial cells (placebo group).

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 breast stimulation by estrogen of normal epithelium cells was decreased by progesterone.

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. 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. 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.

  1. 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.
  2. Another study that was mentioned was “Breast cancer and hormone-replacement therapy in the Million Women Study”.  In this study postmenopausal women were given HRT with synthetic hormones, either estrogen alone or estrogen mixed with a progestin (in British English “progestagen”. After 5 years estrogen alone was associated with a 30% increased risk of developing breast cancer. HRT with an estrogen-progestagen mix was associated with a 100% increased risk of developing breast cancer.
  3. Unfortunately in both of these human experiments the wrong hormone substances were used, 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. 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 has been known for some time that there are 3 stages involved in the development of breast cancer.

  1. Initiation

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 can be used 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, male hormones produced in the adrenal glands that get converted by aromatase into estrogen.

Iodine/iodide has been shown to alter 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

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)

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Probiotics likely stimulate the immune system and help reduce the risk of breast cancer.
  6. 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.
  7. 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.
  8. 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.
  9. 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 that I attended. It became clear that estrogens, when unopposed by enough progesterone, could cause mutations in breast tissue of women and cause breast cancer. He also reviewed two major clinical trials where hormone replacement therapy (HRT) was used. 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 to be learnt from this is that only bioidentical estrogens and progesterone can be used in hormone replacement for menopause. Also, the hormones must be balanced as discussed under point 2 of 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.

Obesity And Diabetes Can Cause Cancer

Dr. Nalini Chilkov gave a talk about how obesity and diabetes can cause cancer. The original title was “Integrative Cancer Care, Increased Rates of Cancer and Cancer Mortality Associated with Obesity and Insulin Resistance, Nutraceutical and Botanical Interventions”. Her talk was presented at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended.

In the following I will present a brief summary of her lecture.

Obesity is a major risk factor for cancer

Obesity causes 14% of all cancer deaths in men and 20% of cancer deaths in women.  This link explains this in more detail. The following 15 cancers were linked to obesity in terms of causation. They are: colon cancer, gastric cancer, gallbladder cancer, ovarian cancer, breast cancer, liver cancer, uterine cancer, endometrial cancer, rectal cancer, pancreatic cancer, cervical cancer, non-Hodgkin’s lymphoma, renal cancer, multiple myeloma and esophageal cancer.

The American Society of Clinical Oncology reported about a meta-analysis involving 82 studies. This involved more than 200,000 women with breast cancer. Premenopausal and postmenopausal women were compared who were obese or normal weight. Premenopausal, obese breast cancer women had a 75% increase in mortality compared to the normal weight breast cancer group. With postmenopausal, obese breast cancer women there was a 34% increase of mortality compared to the normal weight group.

With obese prostate cancer patients there is a similar observation. Obese patients have a more aggressive prostate cancer on the Gleason score and the cancer is in a more advanced stage at the time of diagnosis.

Diabetes increases mortality from cancer

Obesity is a common risk factor for both cancer and diabetes. But diabetes by itself is also increasing mortality of several cancers. In a consensus report details of the relationship between cancer and diabetes have been discussed in detail. The following cancers have been identified to have an increased risk of diabetes: pancreatic, gastric, esophageal, colorectal, liver, gallbladder, breast, ovarian, endometrial, cervical, urinary bladder, renal, multiple myeloma and non-Hodgkin’s lymphoma.

A meta-analysis suggests that cancer patients who are diabetic have a 1.41-fold increased risk of dying compared to those cancer patients who have normal blood sugars. Dr. Chilkov explained in detail what the various mechanism are that account for the faster cancer growth in obese and diabetic patients. High insulin levels is one of the risk factors, so is IGF-1, an insulin-like growth factor. The aromatase enzyme in fatty tissue turns male type hormones into estrogen, which also can stimulate cancer growth.

Carbohydrate restriction diet to prevent obesity

Low carb diets like the Mediterranean diet, the ketogenic diet and the Atkins diet will drop blood insulin and lactate levels. Cancer size and cancer growth are related to insulin and lactate levels. A low carb diet can reduce insulin-mediated uptake of sugar into cancer cells.

Research has shown that cancer metabolism slows down when a 10%-20% carb/high protein diet is consumed by the patient. This reduces the amount of sugar that is taken up by cancer cells. It also reduces insulin, so there is less cancer growth. A ketogenic diet is a more strict way to restrict carbohydrates. Intermittent fasting is also a useful method to reduce carbohydrate intake.

Here is an interesting study that illustrates the power of intermittent fasting. The study involved 2413 patients with early breast cancer who were followed for 7 years. Those breast cancer patients, who consistently did not eat anything between dinner and breakfast for 13 hours or more, had a 36% lower risk of having a cancer recurrence. There was also a 21% lower risk of dying from breast cancer when fasting was done for 13 hours or more overnight.

Supplements to prevent obesity, diabetes and cancer

A low carb diet and in some cases even a ketogenic diet is beneficial as a baseline. A regular exercise program is also useful for general fitness building and cardiovascular strengthening. In addition Dr. Chilkov recommended the following supplements.

  1. To reduce inflammation in the body, Dr. Chilkov recommended taking 2000 to 6000 mg of omega-3 fatty acids per day (molecularly distilled fish oil).
  2. Berberine 500 to 1000 mg three times daily. Dr. Chilkov said that Berberine has anti-cancer properties, improves insulin sensitivity and reduces absorption of sugars in the intestinal tract.
  3. Curcumin inhibits cancer cell division, invasion and metastatic spread through interaction with multiple cell signaling proteins. Several researchers showed that curcumin could lower blood sugar levels by stimulating insulin production from beta cells in the pancreas. Triglycerides, leptins and inflammation in fat cells are also lowered by curcumin. Insulin sensitivity increases through the action of curcumin. Dr. Chilkov recommended 300 mg/day of curcumin for 3 months.
  4. 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 is 1000 to 5000 mg.
  5. Green tea catechins (EGCG) help to normalize the glucose and insulin metabolism. The dosage recommended was 1-3 grams per day.
  6. Reishi mushroom (Ganoderma lucidum) contain polysaccharides with antidiabetic and antiobesity effects. They make gut bacteria produce three types of short-chain fatty acids that control body weight and insulin sensitivity.
Obesity And Diabetes Can Cause Cancer

Obesity And Diabetes Can Cause Cancer

Conclusion

Obesity is a risk factor not only for diabetes, but also for cancer. Chronically elevated blood sugars, increased fasting insulin levels and increased IGF1 levels can cause cancer. In addition they can stimulate tumor growth and increase cancer mortality. It is for this reason that the health care provider should screen all diabetics for cancer. In her talk Dr. Nalini Chilkov gave clear guidelines what supplements will be beneficial to reduce the risk of obesity and diabetes as well as cancer. Start with a healthy, balanced diet. Add an exercise program. Then consider some of the above-mentioned supplements to reduce your risk for cancer, diabetes and obesity.

Genetic Switches To Treat Obesity And Diabetes

Dr. Michael Nova gave a talk recently about the role of genetic switches to treat obesity and diabetes. The talk was given as part of the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas that I attended. The full title of the talk was “Nutritional Genetics and Epigenetics in Diabetes and Obesity Management”. Dr. Michael Nova is the Chief Innovation Officer at Pathway Genomics, San Diego, CA 92121.

Twin studies are a powerful tool to show that longevity is both genetically caused as well as environmentally.

These types of studies have shown that a long life (longevity) has been caused by about 20% from genetics. 80% was contributed by a healthy lifestyle. There are powerful epigenetic factors that can slow down aging and that can interfere with the inflammatory process that causes heart disease, obesity and diabetes. There are specific inflammatory markers done with blood tests that detect inflammation. One of the first inflammatory markers detected was the C-reactive protein.

What diseases are caused from inflammation?

Dr. Nova showed a slide depicting MS and Alzheimer’s disease in the head. In the heart area atherosclerosis was shown to cause heart attacks and strokes. Next diabetes, lupus, obesity and irritable bowel disease were depicted. Finally there is arthritis that interferes with joint movements. All of these conditions have inflammation at the core, which leads to worsening of the conditions, if the inflammation is not stopped through nutritional or medical means.

Age-related diseases also due to inflammation

Inflammation is not only confined to these conditions. Research has shown that the following age-related diseases belong into the inflammatory category. These are: osteoporosis, depression, diabetes, cancer, neurodegenerative diseases (Parkinson’s disease, Alzheimer’s), asthma, central obesity, metabolic syndrome and cardiovascular disease. In these diseases the C-reactive protein is often up, so is the fasting insulin level. The rest of the talk concentrated on how various changes in food intake and supplements could lead to epigenetic changes that improve the patients’ conditions.

Human genetics are complicated

The speaker mentioned how complex the human genetics are, and he showed a number of slides that are too complicated to discuss here. There are unstable genes, which can become important in the development of illnesses, particularly when you don’t exercise and you eat a Standard North American diet. There are genes involved that cause diabetes, but they need environmental triggering to get expressed. Dr. Nova showed one slide that listed two genetic variants, which when activated by inflammation rendered the person positive for diabetes or heart disease. If inflammation is vigorously treated with a Mediterranean diet and Metformin, the hemoglobin A1C will decrease to less than 6.0% and diabetes will disappear.

Obesity and genetic factors

Obesity has a 40% to 60% hereditary rate. The fat mass and obesity-associated gene, FTO gene for short is the reason some people gain weight. When this gene is not present the person has no problem maintaining a normal weight. The FTO gene is located on chromosome 16. There are other genes with complicated names that can also increase weight.

It is important that there are many factors that work together in developing obesity. Dr. Nova called this the “epigenetic modulation”. He explained further that there are at least 12 factors working together that can reduce obesity. These are:

  1. Diet
  2. Diurnal/seasonal correlations
  3. Smoking and other toxic chemicals
  4. Street drug use
  5. Disease exposure
  6. Financial status
  7. Exercise status
  8. Microbiome healthy?
  9. Therapeutic drugs
  10. Alternative medicine
  11. Social interactions
  12. Psychological state

Low carbohydrate diets and the ketogenic diet are helping to reduce weight. Financial stress leads to more cortisol production, which leads to weight gain. An unhealthy bacteria composition in your gut causes you to gain weight, while a good composition of bacteria helps you lose weight. Overcoming depression with cognitive therapy can help reduce your weight. Those are just a few examples in more detail from the list of 12 factors.

Extensive research has shown that genetic factors and environmental factors interact to lead to epigenetic marks or imprinting. These epigenetic factors have an influence on gene expression, but they don’t change the underlying DNA sequencing.

There are still gaps of knowledge how obesity develops, what percentage is due to genetic factors and how much is due to other factors including diets.

Diabetes and genetic factors

Major metabolic processes in our body cells like phosphorylation, acetylation and methylation can be influenced by nutrition. This allows epigenetic mechanism of actions to interfere with the expression of inherited health problems like diabetes and other diseases. This has the potential to improve quality of life.

Useful supplements

Dr. Nora showed a slide with a number of useful supplements.

  • EGCG is the effective component of green tea. It supports the viability of the beta-islets of the pancreas that produce insulin. It leads to more secretion of insulin.
  • Naringin and Hesperidin decrease high blood sugar levels.
  • Anthocyanin decreases high blood sugar levels.
  • Quercetin increases cell proliferation in the liver and the pancreas.
  • Vitamin D3 reduces diabetes incidence and inflammation of the insulin-producing cells.
  • Biotin in combination with chromium increases insulin secretion and lowers blood sugars.
  • Vitamin B2, also known as riboflavin has anti-inflammatory effects.
  • Alpha-lipoic acid protects against diabetes by reducing blood sugar levels.

There are several genes involved in the development of type 2 diabetes, one of them is the FTO gene that is also involved in the development of obesity. But Dr. Nora projected a slide that showed 14 other genes that can be involved in the development of diabetes. I have elected to not get into all of those details.

What Dr. Nora concluded is the fact that nutrition could play a vital role in preventing these genes from being expressed. He talked about silencing genes, which good nutrition and supplements can do.

Silencing diabetes genes

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-3 intake are helping to control inflammation and preserve beta cells in the pancreas in diabetes patients.

Nutritional genetic modifiers are

Foods that methylate DNA and silence genes are: citrus (hesperidin), apples (phloretin) and tomatoes (lycopene). The following foods do both DNA methylation and histone modifications: turmeric (curcumin), cinnamon (coumaric acid), green tea (EGCG), soybean (genistein), coffee (caffeic acid) and broccoli (isothiocyanates). These three foods only do histone modifications: garlic (allyl mercaptan), grapes, (resveratrol) and cashew nuts (anacardic acid).

Functional foods with regard to obesity and diabetes

Here are a few food items and their effects on your health.

  • The lignans of flaxseed lower LDL cholesterol and total cholesterol.
  • The catechins of green tea prevent obesity, but also obesity-induced type 2 diabetes.
  • Saponins of fenugreek lower lipid peroxidation and increase the antioxidant level.
  • Soy proteins contain phytoestrogen, genistein and daidzein; this lowers cholesterol levels in the blood, prevents lipid peroxidation and has antioxidant activity.
  • Banaba leaves extract contains corosolic acid and ellagitannins. These substances are able to lower glucose levels in the blood. It also has an anti-obesity effect.
  • Grapes and related products contain anthocyanin, flavan-3-ols and flavonols. They have blood pressure lowering qualities, lower blood fat levels and prevent hardening of the arteries.
  • Dark chocolate contains flavanols that are the main type of flavonoid found in it. Flavanols decrease blood pressure and make platelets in the blood less sticky. This prevents heart attacks and strokes. In addition LDL cholesterol is decreased.
  • Red wine, berries, pears, and apples: proanthocyanidins are the active polyphenols that make all of these fruit valuable. The antioxidant effects of proanthocyanidins prevent LDL to get oxidized, which in turn slows down hardening of the arteries. It reduces the inflammation associated with narrowing of blood vessels and normalizes the lining of arteries.
  • Onions contain two active ingredients, allyl propyl disulfide (which makes you cry when you cut onions) and S-methyl-cysteine sulfoxide. These substances have anti-diabetic effects and lower blood fatty substances.
  • Turmeric contains curcumin, which possesses antidiabetic properties.
  • Fruit and vegetables contain fiber, which lowers blood sugars and hemoglobin A1C.
  • Stevia from the stevia plant reduces blood sugars following a meal in patients with type 2 diabetes.

In summary, all these substances are examples of triggering epigenetic mechanisms to interfere with the expression of negative inherited health problems.

Genetic Switches To Treat Obesity And Diabetes

Genetic Switches To Treat Obesity And Diabetes

Conclusion

This was a whirlwind review of how genetic and epigenetic traits can be overcome by a healthy diet, by supplements, fruit and vegetables, exercise and other healthy lifestyles. After reading about this huge line-up of substances that can contribute to your health, you may feel slightly overwhelmed. Are you going to get all these wonderful items from the health food store and live on a bunch of supplements? Of course this is not the fact! Some herbals can be extremely helpful to combat inflammation, such as curcumin. But the most essential fact remains very simple: to cut down sugar and too many starchy foods, as they will trigger suppressed genes to cause diabetes, obesity, heart attacks and strokes. We need to inform ourselves and stay vigilant to the fact how toxic processed foods are, and we have to cut them out in order to stay healthy. We can become much more resilient to health challenges than we may have thought possible.

Vitamin D3 Protects Your Brain

More and more studies are showing that vitamin D3 protects your brain. It protects against MS, but also against Parkinson’s disease and Alzheimer’s disease. In the following I will review what evidence there is to support each of these topics.

Vitamin D3 protects your brain from multiple sclerosis (MS)

It has been known for some time that in the northern hemisphere MS is more common because of the lack of sunshine, which in turn produces less vitamin D3 in the skin.

MS is an autoimmune disease where immune cells attack the lining of nerves. Both nerve cells and immune cells have vitamin D receptors. It appears that immune cells are calmed down by vitamin D3 and remission of an MS relapse is more likely.

There are two forms of MS, the relapsing-remitting MS and the progressive MS. The first one (relapsing-remitting) is more common. After a bout of active MS, the illness calms down and the condition of the patient is stable for some time until the next relapse occurs.

With progressive MS there are two forms, primary progressive MS and secondary progressive MS. The primary form is a case of MS where symptoms steadily worsen, without any remission. The secondary form of progressive MS occurs at the end of fairly stable relapsing-remitting MS. Symptoms become more pronounced and the condition deteriorates steadily from there.

Progression and disability in MS patients with various vitamin D3 levels

Dr. Fitzgerald and colleagues published a study in JAMA Neurology in 2015.

They took 1482 men and women who were on interferon beta-1b treatment. This treatment utilizes the immunomodulator interferon beta-1b and reduces the number of relapses in patients with MS. The study took place between November 2003 and June 2005. Results were analyzed between June 2013 and December 2014. The researchers measured vitamin D levels (as 25-hydroxy vitamin D). The vitamin D levels were obtained at baseline, at 6 months and 12 months.

The number of brain lesions were measured by MRI scans. All of the patients also underwent a functional test, called expanded disability status scale. This measured impairment of ambulation, ability to communicate and activity levels.

Results of this study showed marked differences between patients with high and low vitamin D levels. Those patients who had the highest vitamin D blood levels (more than 40 ng/mL) had the lowest rates of new MS lesions. Previous studies had found that a low blood level of vitamin D (less than 25 ng/mL) in patients was associated with a much higher risk of developing MS. Dr. Fitzgerald’s study showed that a 50.0-nmol/L increase in serum vitamin D levels associated with a 31% lower rate of new MS lesions. Patients with the highest vitamin D level of more than 100 nmol/L had the lowest amount of new MRI lesions (47% less than the patients with the lowest vitamin D levels).

Another study showed that a low-dose vitamin D level accelerated MS. There was a 5.9-fold risk converting the initial relapsing-remitting form of MS into the secondary progressive form of MS.

All these studies show that vitamin D3 can decrease the risk of getting MS. In addition vitamin D3 also delays progression in those who have MS.

Vitamin D3 protects your brain from Parkinson’s disease

Vitamin D3 plays a role in preventing Parkinson’s disease.

Parkinson’s disease is a neurodegenerative disease that causes tremor in muscles, causes balancing problems and eventually can lead to dementia. A metaanalysis was done in 2014 and 7 studies where identified to be relevant. The authors were looking for correlation of vitamin D levels with Parkinson’s disease. 1008 patients were included in the metaanalysis with 4,536 controls.

  • Patients with a vitamin D level of less than 75 nmol/L had a 1.5-fold higher risk of developing Parkinson’s disease than the controls.
  • Patients with a vitamin D level of less than 50 nmol/L were at a 2.2-fold higher risk of developing Parkinson’s disease.

Another metaanalysis utilized 5,690 Parkinson’s disease patients and 21251 matched controls.

It found that vitamin D levels of less than 20 ng/ml were associated with a risk of 2.08-fold to develop Parkinson’s disease. Interestingly, vitamin D3 supplementation reduced the risk of Parkinson’s disease by 38%. Outdoor work reduced the risk of developing Parkinson’s disease by 28%.

Vitamin D3 protects your brain from Alzheimer’s disease

Alzheimer’s disease is a neurodegenerative disease of old age. We know that it is much more common in patients with type 2 diabetes where insulin levels are high. Studies have shown that Alzheimer’s disease can be termed type 3 diabetes.

The resulting neurofibrillary tangles and amyloid-beta deposits damage nerve cells, which are responsible for the memory loss and the profound personality changes in these patients.

What does vitamin D3 have to do with this?

A 2014 study showed that a low vitamin D level was associated with a high risk of dementia and Alzheimer’s disease.

Specifically the following observations were made.

  • Vitamin D level of less than 10 ng/ml: 122% increased risk of Alzheimer’s
  • Vitamin D level 10 to 20 ng/ml: 51% increased risk of Alzheimer’s

The same research group found in two trials that vitamin D deficiency leads to visual memory decline, but not to verbal memory decline.

Vitamin D3 combined with metformin suppresses cancer

The newest development with respect to vitamin D3 is the finding that it also has anti-cancer effects. Dr. Li demonstrated that vitamin D reduced prostate cancer cell line growth by 45% while metformin alone reduced it by 28%.

But when both vitamin D and metformin were present in the cell cultures there was growth inhibition of 86%. Dr. Li explained that vitamin D potentiated the growth inhibitory effect of metformin.

Vitamin D3 protects your brain: guidelines to proper vitamin D3 dosing

For years the medical profession stated that 400 IU of vitamin D3 would be enough supplementation. It may be enough to prevent rickets in children. But these low doses will be insufficient in many patients who are deficient for vitamin D to prevent MS, Parkinson’s disease, Alzheimer’s disease or cancer.

A study on medical staff in Northern India showed that 85% of the staff had very low vitamin D levels of less than 10 ng/ml.

It took high doses of vitamin D3 to increase the vitamin D level in the blood.

Generally supplements of vitamin D3 of 5000 IU to 8000 IU are the norm now. But some patients are poor absorbers and they may require 15,000 IU per day. What the patients need can be easily determined by doing repeat vitamin D blood levels (as 25-hydroxy vitamin D). The goal is to reach a level of 50-80 ng/ml. The optimal level with regard to nmol/L is 80 to 200 (according to Rocky Mountain Analytical, Calgary, AB, Canada).

Vitamin D3 Protects Your Brain

Vitamin D3 Protects Your Brain

Conclusion

Many people are deficient with regard to vitamin D, and they do not know it. The most important thing is to do a vitamin D blood test to assess your vitamin D status.

We know for a long time that vitamin D plays a role in bone metabolism and this is why women approaching menopause often need vitamin D3 supplementation. But it may come to you as news that vitamin D3 also protects from MS, Parkinson’s disease and Alzheimer’s disease. In addition, as indicated above, we know that many cancers are suppressed by taking vitamin D3 regularly.

When you realize that all body cells have vitamin D receptors on their surface, it is no surprise that vitamin D3 is so important to take. The vitamin D3 receptors must be there for a reason. If your body is deprived of this valuable vitamin, the high risk of degenerative diseases will be the consequence.

Hidden Cause Of Depression

About 15.7 million Americans suffer from depression every year, but there remains a hidden cause of depression.

Not everybody responds well to antidepressant medicine. Only 30 to 50% of depressed people respond to antidepressants. There are two blood tests many physicians do not know and therefore fail to order: homocysteine blood levels and 5-methylfolate levels (5-MTHF).

Homocysteine as a hidden cause of depression

In 2004 a research group studied 924 middle-aged men. They noted that those men who fell into the highest third of homocysteine levels had a two-fold higher risk of being depressed than those who fell into the lower third of homocysteine levels. Other studies showed that SAMe, a nutrient that is required to build up mood enhancing neurotransmitters was sadly lacking in depressed people. In addition, folate levels were also found to be low in depressed people.

Having found this association between lack of nutrients and depression offered new opportunities to treat depression. Two studies examined the effect of taking 5-methylfolate on the effect of antidepressants. The result was astounding: in one study 7% of patients taking an antidepressant experienced improvement of their depression when assessed with a standard depression score. However, the same group improved their depression by 19% when 5-methylfolate was given in addition to the antidepressant.

Patients with the most severe depression on antidepressants had a 16% improvement of their depression. Adding 5-methylfolate to the antidepressant caused a 40% overall improvement in these severely depressed people, 24% more than without this simple vitamin supplement.

There is other evidence that patients with depression recover faster in the presence of 5-methylfolate. Moderately depressed patients recovered within 231 days on antidepressants alone, but in only 177 days when 5-methylfolate was present as well. The most severely depressed patients recovered within 150 days with antidepressants alone, but recovered within only 85 days on 5-methylfolate and the antidepressant.

Hidden cause of depression and Alzheimer’s disease

The story is getting more involved. Depression is related to proper balance of neurotransmitters that can be influenced by antidepressants and 5-methylfolate. But new research showed that Alzheimer’s disease (dementia) patients with cognitive decline have elevated homocysteine blood levels. A study in the New England Journal of medicine in 2002 found that after 8 years of observation more than 75% of them were diagnosed with Alzheimer’s disease. When blood homocysteine levels exceeded 14 micromole per liter the risk of Alzheimer’s had doubled compared to those with normal homocysteine levels. The researchers concluded that homocysteine is an important risk factor for the development of Alzheimer’s diseases and dementia, although it is not the only one.

Methylation pathway defects as a hidden cause of depression

40% of the population is defective in one or more genes that control the so-called methylation pathway in each of our cells (Ref. 1). This can slow down the metabolism of brain cells including the synthesis of certain neurotransmitters. At the same time it can cause the rising of homocysteine, which is then a useful marker for methylation defects. Another marker is the 5-methyl folate level, which, when low, indicates a deficiency in methyl donors including 5-methylfolate (5-MTHF).

Mental illness is an area where epigenetic factors play an important role. Depression that responds only partially or not at all to SSRI’s (antidepressants) often responds to L-methylfolate, a simple supplement from the health food store as a supplement. Similar epigenetic approaches can be used to treat psychosis, schizophrenia, bipolar disorder and Alzheimer’s disease.

Other illnesses due to methylation defects

Dr. Rozakis mentioned that 92% of migraine sufferers have a defective methylation pathway involving histamine overproduction and they can be helped with a histamine-restricted diet (Ref.2).

Autism, ADHD (hyperactivity) and learning disabilities are other diseases where methylation pathway defects are present. Every patient with autism should be checked for methylation pathway defects, and appropriate supplements and diet restrictions can help in normalizing the child’s metabolic defects. DAN physicians (“defeat autism now”) are well versed in this and should be consulted.

S-adenosylmethionine (SAMe) defects are another type of methylation defect, which is associated with certain liver, colon and gastric cancers.

Dr. Rozakis went on to say that methylation defects lead to disbalances between T and B cells of the immune system and are important in autoimmune diseases like lupus or rheumatoid arthritis.

Methylation defects can also cause autoimmune thyroiditis and type 1 diabetes. They can also cause cardiac disease by raising homocysteine levels, which causes dysfunction of the lining of arteries and premature heart attacks.

Epigenetic factors through global methylation defects from vitamin B2, B6 and B12 deficiency can cause many different cancers. Hypomethylation is the most common DNA defect of cancer cells.

With skin diseases it has come to light that atopic dermatitis, eczema, psoriasis, scleroderma and vitiligo are related to methylation.

When we age, certain hormones are gradually missing, which leads to menopause and andropause. This leads to impaired cell function, elevated cholesterol, arthritis, constipation, depression, low sex drive, elevated blood pressure, insomnia, irritable bowel syndrome and fatigue. Replace the missing hormones with bioidentical ones, and symptoms will normalize.

Tests and treatment for hidden cause of depression

It is important for a physician to test patients for homocysteine levels once per year. As we age, we tend to lose some of the methylation pathway enzymes, which can result in an increase of homocysteine in the blood. A normal homocysteine level is less than 7 to 8 micromoles per liter. This is lower than the commonly recommended 15 micromoles per liter.

If the homocysteine level is too high, the treatment consists of methionine containing foods like dairy products and meat. Methionine, an essential amino acid, functions as a donor of methyl groups, which will normalize the methylation pathway defect and allow the homocysteine level in the blood to decrease. Research studies have been using 1000 to 5000 micrograms of 5-methyl folate daily to reduce homocysteine. Other B vitamins are necessary to reduce homocysteine, like vitamin B2, B6 and B12 in addition to 5-MTHF.

Hidden Cause Of Depression

Hidden Cause Of Depression

Conclusion

Depression and several other illnesses that are related to methylation pathway defects can be caused by a lack of 5-MTHF resulting in high homocysteine blood levels. It is important for elderly patients to be checked for homocysteine blood levels once per year to prevent depression, Alzheimer’s disease, migraines and a number of other illnesses mentioned above.

Once a methylation pathway defect has been identified, it is relatively easy to treat the patient with a proper methionine rich diet and 5-MTHF supplements as well as other B vitamins as discussed. It can prevent a lot of disability and human suffering.

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. As people do 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 not much attention was paid 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.

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” with an age-adjusted cancer incidence of 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. This likely explains the lower cancer rate in the GrassrootsHealth cohort. In order to increase the statistical significance the two trials were combined. 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

  1. 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.
  2. 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 was associated with 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).
  3. 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. They 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.
  4. 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

  1. 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. As we know that low levels of vitamin D are associated with higher cancer frequency it is important to use vitamin D3 as supplements in our diet.
  2. 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. When cancer cells are becoming more specific cells uncontrolled multiplication is much more difficult. 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 (particularly in diabetics), osteoporosis and Alzheimer’s disease.
