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. Newer research has shown that tocotrienol is more powerful than tocopherols. I take 125 mg of tocotrienols daily.

What lowers LDL cholesterol?

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!

Where Does Fat Go With Weight loss?

People often wonder where does fat go with weight loss? This question recently came up in a CNN conversation.  The answer was originally researched by Dr. Ruben Meerman and Professor Andrew Brown.

Dr. Meerman is an assistant scientist at the University of New South Wales and author of “Big Fat Myths: When You Lose Weight, Where Does the Fat Go?” Professor Brown is the head of the School of Biotechnology and Biomolecular Sciences at the same university.

When you lose 1 kilogram of fat, where does fat go with weight loss?

The interesting answer to this question is that fat gets metabolized. Dr, Meerman and Prof. Brown pointed out that originally Leifson et al. answered this question who used heavy oxygen and found out that this was metabolized into heavy water.

Technically these experiments are fairly complex, but they allow the researchers to see exactly where the body incorporates these chemicals and where they end up with breakdown of fat. The BMJ paper describes that the breakdown of 1 kg of fat follows the following pattern: It breaks down into 0.84 kg of CO2 (carbon dioxide) and 0.16 kg of H2O (water). In other words, the lungs are the primary organs that get rid of fat and the kidneys excrete the water. There is a bit of extra energy in this chemical reaction as well, which dissipates through the skin and through exhaled air.

What did health professionals think where the fat would go?

The health professionals were doctors, dieticians and personal trainers. About 65% of them thought fat would evaporate into energy/heat. About 10% thought fat would end up in the feces. 5% thought fat would turn into muscle. Another 5% thought fat would turn into sweat or urine. 8% were correct that fat would become CO2 and H2O. 7% said they did not know.

The chemistry of fat deposits and metabolizing fat

The body deposited triglycerides from the liver metabolism of sugar and fatty acids into fat cells and stored them as oleate (C18H34O2), palmitate (C16H32O2), and linoleate (C18H32O2). Part of this are many chemical reactions, including a number of enzymes. These fatty acids form esters and turn into gigantic molecules with this chemical formula: C55H104O6. The BMJ paper further says that an overall chemical description of metabolized fat would look like this:

C55H104O6+78O2→55CO2+52H2O+energy. In plain English it means that 1 molecule of fat ester (from fat storage) is metabolized together with 78 molecules of oxygen. This results in 55 molecules of carbon dioxide, 52 molecules of water and energy.

Fat turns into carbon dioxide and water

Based on this chemical reaction a calculation of the breakdown of fat into carbon dioxide and water was possible. The surprising result is that 84% of fat becomes carbon dioxide and only 16% of fat becomes water. We exhale the carbon dioxide from our lungs and it is mostly the kidneys that excrete the water. People who lose weight are aware that they have to urinate more often. But they do not notice that they get rid of a lot of carbon dioxide, as this is a subtle process.

Some observations from the fasting mimicking diet

The fasting mimicking diet (FMD) was at the center of the most recent anti-aging conference in Las Vegas I attended. This was the 25th Annual World Congress on Anti-Aging Medicine in Las Vegas, Dec. 14-16, 2017. Late in December 2017 I started 5 days of FMD and have just completed my 4th round of it (FMD is done 5 days out of each month). My main interest in doing this is to prevent heart attacks and strokes and I like the idea of stimulating telomeres for anti-aging and increasing stem cell production. See more details under this link.

Personal experience of fasting mimicking diet

I keep meticulous records of my body measurements using daily body composition scales, which I record in a booklet. Between March 23, 2018 and March 28 I lost 1.5 kg from 64.8 kg to 63.3 kg. Fat composition was reduced from 14.1% to 12.2%. Visceral fat was reduced from 6% to 5%. My muscle percentage rose from 38.1% to 39.1%. The basic metabolic rate was 1471 Calories on March 23 and went down to 1449 Calories on March 28. My body mass index went from 22.0 to 21.5.

I definitely noticed the frequent urination, something I had noticed in the past in 2001 when I lost 50 pounds over 3 months. Of course it is understandable when you reduce your daily calorie intake to 600 Calories per day that you will lose this amount of weight. People have different metabolisms. It may be that you won’t lose as much as I did.

What causes mainly weight loss?

There are many people who think that extra exercise would help you lose weight. But a publication has established that only about 8% of weight loss is due to exercising. 92% of weight loss is due to dieting.

Regular exercise is important for conditioning of your lungs, heart, muscles and joints. But to keep things in balance a reasonable diet, like a Mediterranean diet, should also be part of the regimen.

Sugar overconsumption

The obesity wave in the US started to take off between 1976 and 1980. 40 years later it is still rising. It is interesting to note that both wheat flour and sugar consumption in the US were increasing parallel to the rising obesity figures. In the 70’s the old-fashioned wheat has changed into the force hybridized Clearfield wheat, which is now 100% of the commercially available wheat. Clearfield wheat contains 7-fold higher gluten amounts than the old-fashioned wheat that your grandparents consumed. Gluten stimulates your appetite, so you crave more wheat and you crave more sugar. This becomes a vicious cycle.

Excess calories are stored as fat

The liver metabolizes sugar from regular food and from processed food into triglycerides and LDL cholesterol (the bad cholesterol that plugs up arteries). As I mentioned above, the body stores any excess triglycerides as fat and deposits the excess into fatty cells. You see from this that essentially sugar and wheat end up as fat deposits. I suggest you change your food intake into eating sensible food with fewer calories. Start by eliminating most of your sugar, wheat and processed food intake. This will help you to melt fat away as I showed with an example of my 5 day FMD.

Where Does Fat Go With Weight loss?

Where Does Fat Go With Weight loss?

Conclusion

I reviewed facts about the chemistry of melting fat away. The question is where does fat go with weight loss? In the process of weight loss fat breaks down into carbon dioxide and water. I also documented how you can lose fat in just 5 days (1.1 kilogram) on a 600-calorie diet and reduce the body mass index from 22.0 to 21.5.

Most people do not recognize the importance of watching their diet to achieve weight loss. 92% of weight loss occurs as a result of dieting. Wheat and sugar consumption have a direct connection to the obesity wave that started between 1976 and 1980. I have cut out all wheat, all sugar and all processed food in 2001. This allowed me to lose 50 pounds then and my body mass index today is 21.5. It can be done, even if you are 73 years old.

Prevent Plugged Arteries

There are several ways to prevent plugged arteries, which will translate into less heart attacks and strokes. The message is simple: if you get less heart attacks and strokes, you will live longer. Below I am examining ways to prolong life by various ways to prevent plugged arteries.

You probably heard of plaque formation in the arteries. This is the process where a combination of fat, calcium, cholesterol and cell waste forms a deposit (plaque) under the lining of the arteries.

The end result is that the blood won’t be flowing freely through the affected arteries. This can cause a heart attack or a stroke. Essentially, this is the point where a clot forms in the narrowed passage of the artery. It is also the point, when the clinicians make a diagnosis of a heart attack or a stroke.

Let’s examine what leads to plaque formation in the arteries.

Trans fats

Trans fats are contained in fried foods like French fries, in margarines and other butter substitutes. As margarine is a common ingredient of cakes, cookies, pastries and pies, these are all bad news for our heart health. I consider them off limits. If you eat those foods, you build up plaque in your arteries, which leads to premature heart attacks and strokes.

Lack of exercise

It has been common knowledge for a long time that being sessile leads to premature hardening of the arteries. In the late 1800s to the early 1900s physical exercise was promoted in various countries around the world.

The latter part of the 20th century saw a renaissance of the fitness movement. It was trendy to go running, cycling, and swimming or working out at a gym. It is not only trendy but healthy: cardiologists support all of these sports to help people stay healthy and keep the arteries free from plaque formation.

Too many refined carbs

Sugar and processed foods, especially those with added sugar to improve flavor, have a direct relationship to heart attacks and strokes. It is known that sugar causes high LDL cholesterol and high triglycerides. In addition sugar also causes inflammation of the arterial walls, which causes plugged arteries. However, sugar is only part of the problem. Starchy foods like rice, noodles, cakes, cookies and other foods made with flour get broken down into sugar. Both lead to insulin production. And both lead to changes of the lining of the arterial walls.

In the 1980s and 1990s there was a school of thought that a low fat diet would be healthy in terms of heart attack and stroke prevention (the low fat/high carb diet). This turned out to be a nutritional disaster: the high carb content of such a diet was the problem. It led to weight gain, obesity and death.

Red meat is a problem

Several studies have documented that saturated fat from red meat is only part of the problem. The other part is carnitine, which is abundantly present in beef, pork, lamb and venison. But mortality of people eating unprocessed red meat is only marginally elevated. It is when people eat processed red meat that there is a significant rise in mortality from heart attacks and strokes. This study examined this. They found that gut bacteria were stimulated by red meat to produce substances that stimulate bacteria in your gut to secrete TMA and TMAO, which makes your platelets more sticky and contributes to plugging your arteries. This research paper from the Cleveland Clinic explains it in more detail.

What must I do to prevent plugged arteries?

Eat the right food

A Mediterranean diet is anti-inflammatory. It contains lots of vegetables, but little red meat. Fish and chicken that contain much less L-carnitine are more dominant in Mediterranean food. As mentioned above, you want to avoid trans fats. And you also want to avoid sugar and too many starchy foods. This includes sugar-sweetened beverages. Making these changes will keep your insulin levels in the normal range eliminating inflammation in your arteries. Avoid eating processed foods, because they contain food preservatives and lots of sugar that we want to avoid. Eat more unsaturated fats like avocados, walnuts, olives, trout, herring, and salmon. The last three contain marine-derived omega-3 fatty acids that are particularly helpful in preventing heart attacks and strokes by being anti-inflammatory and by elevating the protective HDL cholesterol. Drink lots of green or black tea, rooibos tea, or ginger tea. They contain antioxidants and bioflavonoids that prevent plugged arteries.

Regular exercise

Many publications have shown that regular physical exercise will lower blood pressure, condition your muscles including your heart and lower mortality.

Only 10 minutes of brisk walking every day reduced the death rate by 33% compared to those who did not exercise at all.

Regular physical exercise does not only prevent heart attacks and strokes, it also reduces the risk of getting another 35 chronic diseases, as the link shows.

Here are some common exercises: jogging, cycling, running, brisk walking, swimming, playing tennis and doing aerobics. All of them will strengthen your muscles and condition your heart and lungs.

Other ways to prevent plugged arteries

Smokers must quit smoking, as smoking has been identified as a major risk factor for heart attacks and strokes.

Exposure to prolonged stress is a factor that leads to hardening of arteries. Stress management is possible by counseling, by self-hypnosis, yoga, tai chi and other relaxation methods.

Risk factors associated with plugged arteries

We already have mentioned the risk factors that are associated with clogged arteries. But for clarity I would like to repeat the major risk factors here.

  • Smoking
  • High blood pressure
  • Elevated LDL cholesterol (the bad cholesterol)
  • Reduced HDL cholesterol (HDL is increasing with exercise)
  • Obesity (often associated by ingestion of too many carbs)
  • Insulin resistance and diabetes
  • Lack of exercise (too much sitting in front of the TV or doing computer work)
  • Unhealthy diet (Standard American diet instead of Mediterranean diet)
Prevent Plugged Arteries

Prevent Plugged Arteries

Conclusion

We often think that we have no input whether or not we get a heart attack or a stroke. This is completely wrong. If you adopt the solutions I have listed here, you can change things for the better. You will reduce your risk to get a heart attack or a stroke. Treat high blood pressure. Stop smoking. Cut out sugar and starchy foods to reduce triglycerides and LDL cholesterol. Exercise regularly and your HDL will protect you from heart attacks and strokes. Shed pounds, if you are obese by starting a Mediterranean diet and cutting out sugar. This will also improve your insulin resistance or diabetes. Start daily exercise as this reduces your risk of a heart attack or a stroke. In addition exercise reduces the risk of 35 chronic diseases that have also been mentioned in one of the links.

Breast Cancer Risks

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

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

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

Balance between estrogen and progesterone

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

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

Progesterone concentration in breast lumps after progesterone cream applications

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

Progesterone cream applied to breasts of premenopausal women

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

How to measure progesterone levels

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

Blood progesterone levels are unreliable

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

Historical failure of estrogen replacement therapy (ERT)

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

Researchers prematurely terminated Women’s Health initiative

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

Breast cancer in the Million Women Study from synthetic hormones

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

Huge difference between bioidentical hormones and synthetic hormones

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

Individualizing bioidentical hormone prescriptions based on blood tests

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

Breast cancer develops in three stages

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

  1. Initiation

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

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

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

  1. Promotion

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

  1. Progression (includes invasion and metastases)

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

The fallacy of overdosing or underdosing

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

Measures that help prevent breast cancer

Supplement only with bioidentical hormones

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

Progesterone to estrogen ratio

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

Eat more fiber containing foods and less beef

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

Calcium supplement

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

Reduce breast cancer risk with probiotics

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

No pollutants and toxic chemicals

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

Other useful supplements

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

Methylation of catechol estrogens

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

Healthy lifestyle (diet , exercise) helps your immune system

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

Breast Cancer Risks

Breast Cancer Risks

Conclusion

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

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”. She presented her talk 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 related 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. The researchers compared premenopausal and postmenopausal women 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. In comparison with the normal weight group the postmenopausal group of obese breast cancer women showed a 34% increase of mortality.

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 signalling 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

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.

Cardiovascular Disease And Inflammation

Dr. Mark Houston talked about cardiovascular disease and inflammation – “the evil twins”. He presented this lecture at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas. Dr. Houston is an associate clinical professor of medicine at the Vanderbilt University Medical School in Nashville, TN 37232.

New thinking about cardiovascular disease and inflammation

Dr. Houston pointed out that the old thinking about cardiovascular disease is defunct, needs replacing and, of course, that the new thinking needs to take its place. Specifically, here are a number of points regarding the new thinking.

  1. Coronary heart disease and congestive heart failure are diseases of inflammation. In the same fashion, oxidative stress, vascular immune dysfunction and dysfunction of the mitochondria are also part of them.
  2. Moreover, in the past it was difficult to reduce these cardiovascular diseases. In contrast, with the new thinking there are now new treatment approaches that help cure cardiovascular disease.
  3. On the whole, the development of heart disease has a long history. First, endothelial dysfunction predates coronary artery disease by many years. Second, the next step is vascular smooth muscle dysfunction. Finally, inflammation develops and structural changes occur in the small and larger blood vessels with atheromatous deposits (plaques) and final occlusion, at which point you get a heart attack.

New approach to the old problem of plugged coronary arteries

Canadian physician Sir William Osler has already stated more than 100 years ago “A man is as old as his blood vessels”. In the first place, the old thesis was that cholesterol would lead to deposits that close coronary blood vessels and cause heart attacks. Dr. Houston called this the “cholesterol-centric “ approach. In reality, the truth is that with conventional blood tests you are missing 50% of all the high-risk patients that are going to develop heart attacks. They are missing the ones that have chronic inflammation, but normal cholesterol levels.

Coronary artery damage from cholesterol elevation versus inflammation

What was not common knowledge in the past was that oxidative stress associated with normal aging can also lead to chronic low-grade inflammation. This oxidative stress leads to mitochondrial DNA changes. Associated with it are biochemical changes that cause chronic inflammation, which in turn will affect the lining of the arteries. The literature describes a metabolic change that known as metabolic syndrome. It leads to high blood pressure, hardening of the arteries and eventually heart attacks and strokes. Accordingly, the key today is to include in screening tests all parameters that will predict who is at risk to develop a heart attack or not.

Blood tests to screen for cardiovascular disease and inflammation

The physician should check blood tests and health history for dyslipidemia, high blood pressure (hypertension), hyperglycemia, smoking, diabetes, homocysteinemia, obesity etc. Also, patients with high GGTP (gamma-glutamyl transferase) levels in the blood are more at risk to develop diabetes. This in turn leads to inflammation of the arterial wall and heart attacks. There are 25 top risk factors that account for all causes of heart attacks.

Briefly, apart from the 7 factors already mentioned above the physician wants to check for high uric acid levels (hyperuricemia), kidney disease, high clotting factors (fibrinogen levels), elevated iron levels, trans fatty acid levels, omega-3 fatty acid levels and omega-6 to omega-3 ratio, low dietary potassium and magnesium intake with high sodium intake, increased high sensitivity C reactive protein level (hs CRP measuring inflammation).

Further high risk factors for coronary artery disease

The list to test for cardiovascular disease risk continues with blood tests for vascular immune dysfunction and increased oxidative stress, lack of sleep, lack of exercise, subclinical low thyroid levels, hormonal imbalances for both genders, chronic infections, low vitamin D and K levels, high heavy metals and environmental pollutants.

The speaker stated that he includes a hormone profile and vitamin D levels. He does biochemical tests to check for mitochondrial defects. Micronutrients are also checked as cardiovascular patients often have many nutritional deficiencies coupled with cardiovascular factors. Inflammation is monitored through testing the levels of C-reactive protein (CRP).

The Rasmussen score

In order to assess the risk of a patient Dr. Cohen, a cardiologist has developed the Rasmussen score, which is more accurate than the Framingham score.

The following tests are performed on the patient: computerized arterial pulse waveform analysis (medical imaging), blood pressure at rest and following exercise and left ventricular wall of the heart by echocardiography. Further tests include urine test for microalbuminuria, B-type natriuretic peptide (BNP, a measure of congestive heart failure), retinal score based on fundoscopy, intima-media thickness (IMT, measured by ultrasound on the carotid artery) and electrocardiogram recording (EKG).

Here is what the Rasmussen score means:

  • With a disease score of 0 to 2: likely no heart attack in the next 6 years
  • The disease score is 3 to 5: 5% likely cardiovascular events in the next 6 years
  • Disease score > 6: 15% likely cardiovascular events in the next 6 years

Non-intervention tests to measure cardiovascular health

1. The ENDOPAT test

With this test the brachial artery is occluded with a blood pressure cuff for 5 minutes. Endothelial dysfunction is measured as increased signal amplitude. A pre- and post occlusion index is calculated based on flow-mediated dilatation. The values are interpreted as follows: an index of 1.67 has a sensitivity of 82% and specificity of 77% to predict coronary endothelial dysfunction correctly. It also correlates to a future risk for coronary heart disease, congestive heart disease and high blood pressure.

2. The VC Profile

This test measures the elasticity of the arteries. There is a C1 index that measures the elasticity of the medium and smaller vessels and the C1 index, which measures elasticity of the larger arteries and the aorta. The smaller the numbers are, the less elastic the arterial walls.

3.The Corus CAD score

This is a genetically based blood test. The score can be between 0 and 40. If the score is 40, there is a risk of 68% that there is a major blockage in one or more coronary arteries.

4. Coronary artery calcification

The CAC score correlates very well with major event like a heart attack. There is a risk of between 6- and 35-fold depending how high the CAC score is. The key is not to wait until you have calcification in your coronary arteries, but work on prevention.

Treatment of cardiovascular disease and inflammation

When the doctor treats heart disease, all of the underlying problems require treatment as well. It starts with good nutrition like a DASH diet or the Mediterranean diet.

Next anti-inflammatory and other supplements are added: curcumin 500 mg to 1000 mg twice a day, pomegranate juice ¼ cup twice per day, chelated magnesium 500 mg twice per day, aged garlic 1200 mg once daily, taurine 3 grams twice per day, CoQ-10 300 mg twice per day and D-ribose 5 grams three times per day. This type of supplementation helps for chest pain associated with angina. On top of this metabolic cardiology program the regular cardiac medicines are also used.

Additional supplements used in the metabolic cardiology program may be resveratrol 500 mg twice per day, quercetin 500 mg twice per day, omega-3 fatty acid 5 grams per day, vitamin K2 (MK 7) 100-500 micrograms per day and MK4 1000 micrograms per day. In addition he gives 1000 mg of vitamin C twice per day. This program helps in plaque stabilization and reversal and reduction of coronary artery calcification.

Case study showing the effect of metabolic cardiology program

Here is a case study where Dr. Houston treated a heart patient. He was a white male, first treated for congestive heart failure as a result of a heart attack in June 2005. Initially his ejection fraction was 15-20%. His medications were: digoxin 0.25 mg once daily, metoprolol 50 mg twice per day, ramipril 10 mg twice per day, spironolactone 25 mg twice per day and torsemide 20 mg once daily. These medications remained in place, but the patients followed the metabolic cardiology program in addition. Here are the results of his ejection fraction (EF) values after he was started on the metabolic program:

  • Initial measurement: EF15-20%. Marked shortness of breath on exertion.
  • 3 months: EF 20-25%. He reported improved symptoms.
  • 6 months: EF 25-30%. He said that he had now minimal symptoms.
  • 12 months: EF 40%. He had no more symptoms.
  • 24 months: EF 50%. He reported: “I feel normal and great”.
  • 5 years: EF 55%. He said” I feel the best in years”.

A normal value for an ejection fraction is 55% to 70%.

Cardiovascular Disease And Inflammation

Cardiovascular Disease And Inflammation

Conclusion

Testing for heart disease risk has become a lot more sophisticated than in the past, and the tests have opened up a window to early intervention. Metabolic cardiology is a new faculty of cardiology that assists in the reversal and stabilization of heart disease. It will help high blood pressure patients and stabilizes diabetes, which would otherwise have deleterious effects on heart disease. Metabolic cardiology improves angina patients. It also prevents restenosis of stented coronary arteries. As shown in one clinical example reduced ejection fractions with congestive heart failure will improve. The metabolic cardiology program achieved all of these improvements.

As usual, prevention is more powerful than conventional treatment later. To give your cardiac health a good start, don’t forget to cut out sugar, exercise regularly and follow a sensible diet.

Commuting Affects Your Health

A research report from Great Britain was recently reviewed by CNN; it revealed that commuting affects your health.

The longer we commute to work and back the more downtime we have where we do not move our muscles. But we also are exposed to more unhealthy snacks and sugary drinks that make us deposit more fat. The original research report was published here. What were the elements of this study?

Commuting affects your health, study design

Three consecutive annual waves of the British Household Panel Survey were utilized. These are longitudinal surveys of nationally representative households in Great Britain. The sample years were 2004/2005, 2005/2006 and 2006/2007. There were 15,791 participants in the study; of these 4,056 entered the study. The main mode of travel to work was determined at each time point. The self-reported height and weight was taken to calculate the body mass index (BMI) at baseline and at 2 years. Attention was paid to switches of transportation mode (that is from active to sedentary and vice versa).

Commuting affects your health, results of study

  1. Switching from car commute privately to active travel (walking, bicycling) or public transport resulted in a significant loss in BMI. There were even larger reductions of BMI’s in those who enrolled in the first year in active transportation, because of the longer exposure. Those with the longest journeys who used active transportation had significant weight losses.
  2. A group of 787 people switched from active travel or public transport to the use of their private cars as transportation. This resulted in a significant BMI increase.
  3. The study concluded that any interventions that would allow private car commuters to switch to an active mode of transportation could contribute to the population’s BMI being reduced significantly.

Commuting affects your health, Cambridge experiment

In a 2016 study from Cambridge (Great Britain) a similar experiment was done. They studied traffic patterns in the county of Cambridgeshire. The city compared 1143 adults working in the city with 1710 people who used the Cambridgeshire Guided Busway. The public had access to a new bus network that has connections with pedestrian pathways and cyclists since 2011. Longer commuting journeys incorporated walking and cycling, for which otherwise people used a private car and public commute. When officials explained the benefit of active travel to people, there was a 1.8-fold increase of active travel. There was also a 2-fold decrease of commuting solely by car. The weekly cycling commuting time had increased to 1.34-fold compared to the previous level.

Active commute most beneficial

People who at baseline were the vast majority in being inactive in their commute, were the ones who appreciated an active commute most. There was an association of active commuting, greater overall physical activity with an improvement of health and weight loss.

Commuting affects your health, US study

A multi-city study involved the largest 3,914 municipal jurisdictions, which were located in 473 of the most populous U.S. counties. This involved 48 states and the District of Columbia. In order to encourage more active commuting (walking, cycling) many municipalities developed pedestrian zones or pedestrian-friendly zones with adjacent bus transportation. A new concept of transit-oriented developments or districts (TODs) was adopted. TODs are higher density areas that are compact. They are mixed use areas, which you find around transit stops. This encourages walking. The study was completed in 2016. It showed that the TOD zones had higher occupancy rates. Many house owners had no car as they commuted using public transportation only.

Summary about transit-oriented developments or districts (TODs)

TOD zones were more populous, people in it had higher income, and they were more racially diverse and younger. The occupants of TOD zones had a 2.1-fold higher rate of using public transportation and they also had a 2.48-fold higher rate of using active transportation to work.

Commuting affects your health, general comments

The majority of commuters in England and Wales spent 56 minutes in their cars going to and from work in 2013. In London this daily commuting time is 79 minutes. The US data are similar.

With a well-developed public transportation system the authorities developed various programs designed to replace at least some part of the commute by active commuting. This is good for your metabolism, it is good for your cardiovascular status and it gets you away from snacking junk foods driving in your car.

Commuting leads to stress

A survey from London, England polled more than 1500 commuters. 55% reported increased stress levels, 33% reported increased snacking, 29% admitted to fast food consumption, 36% complained about sleeping problems, 41% said that they reduced physical activity and 44% reported that they had less quality time with their friends and family. 58% felt that flexible work hours would improve their health and wellbeing. Remember that how you are commuting affects your health.

My own experience watching commuting in various cities

Over the years I have traveled extensively in Germany, Austria and the US. In Europe it is interesting how many years ago the pedestrian zones in the old town centers have reshaped the commuting. The U-Bahn (subway) and commuter trains have intermingling networks that shoot you out to pedestrian zones. There is no escaping from it, you have to walk before you can catch a connecting bus or tram.

Vienna (Austria)

Vienna (Austria) for instance allows you to get out at the U-Bahn station of Stephansplatz, which is a pedestrian zone around the Stephan’s Church (Stephanskirche). There is an amazing array of shops and in a side alley you can even find a Starbucks, if this is what you are looking for. When you walked enough, you hop onto any of the U-Bahn connections. This brings you where you need to be. If you are too far from your goal, hop onto a tram and enjoy the sightseeing. There are also buses that can get you there. It is all covered under the same Vienna card, which I appreciated as a visitor. It is best to park your car in the periphery and use the commuting network to get you to where you want to go.

Munich (Germany)

Munich (Germany) has a lot of cycle paths, which run parallel to the pedestrian paths. I was interesting to see business people in black suits cycle to work. Otherwise there are the U-Bahn, S-Bahn, trams and buses that all interconnect.

Münster (North Rhine-Westphalia, Germany)

Münster (North Rhine-Westphalia, Germany) has an extensive network of cycle paths and pedestrian walks. Buses and trams are also constantly running. The old historic town is a pedestrian zone, but anybody can commute to anywhere between walking or using the bus/tram. I found it astonishing this spring when I visited; there were hundreds of people, young and old cycling to and from work. The employers are providing huge metal racks where people can attach their bikes to with a lock.

Berlin

Berlin is another multi level commuting city in Germany. You can use the U-Bahn, S-Bahn (commuter train), bus or tram to get to work. Here is an informative video that explains.  I did not see many cyclists there. But hundreds of people are walking. Yes, there are many pedestrian zones and they interconnect with all of the commuter options. Berlin spreads over a vast area, so the S-Bahn, which is a local commuter train is particularly important. For the shorter connecting trips people commute by the U-Bahn (subway). Buses and trams plus walking do the fine-tuning to get to your destination.

Vancouver (BC, Canada)

Vancouver (BC, Canada) has some cycle pathways in the West end, close to Stanley Park. Otherwise there is a network of buses, the Skytrain, Sea Bus (between North Vancouver and downtown) and the West Coast Express (a commuter train). For the size of the city I think that Vancouver could benefit from studying some of the transportation modalities in Europe to entice the car travelers to use public transportation. When I travel to Vancouver, I use my own car, as it is so much faster to reach any goal. Public transportation is at this point not effectively connecting all the areas in this city.

Commuting Affects Your Health

Commuting Affects Your Health

Conclusion

In the past we often heard that there was nothing that could be done about traffic jams and commuter stress. Think again. Revitalization of city cores all over Europe, Great Britain and in the US has taken the TOD concept to heart and active commuting has become a reality. Whenever you can, use alternatives like cycling, walking and public transit to get to and from work. Studies have even shown that when you become an active commuter you likely will also become more active after work. Even using public transit makes the commute more active, as you are not sitting for an hour or more in your vehicle.

Use public transit, not your own car to commute

You have to get out and walk in order to catch a connection. This all helps to keep you physically more fit than the commuting style, where you sit in a vehicle and possibly dip into junk food. It is not only about body mass index reduction and decreasing your waistline. Active commuting is also a lot less stressful than the passive modality, where traffic jams add to frustration and stress at the beginning and at the end of a workday.

Seven Steps To Live Over 100 Years

Forbes invited me to publish a blog I wrote for Quora, “Seven steps to live over 100 years”.

The topic of habits by people who live more than a hundred years has been reviewed many times in the media. It continues to be popular. Here are seven things you can do to stay healthy followed by an explanation why.

Seven steps to live over 100 years – step1: Stay active

You want to stay active every day, even if you retire. You want to move and keep your mind busy. Part of that is to do a daily formal exercise routine to keep those muscles toned, which will prevent falls in the future.

Explanation: when you keep your muscles toned and you move about, your balance organ and coordination remains sharp, you are less likely to fall and break a hip. 50% of those who sustain a hip fracture die.

Seven steps to live over 100 years – step 2: Eat a healthy diet

Eat a Mediterranean type diet or follow the Okinawan diet. These diets contain less meat (or no meat as in the Seventh Day Adventist diet), but lots of vegetables and fiber. This keeps your cholesterol down, your arteries open and your metabolism controlled, preventing diabetes. If you are not obese and you have no diabetes, you are going to be OK with your cardiovascular system for decades to come.

Explanation: Heart attacks are still on top of the mortality list. Avoid them and you got it made, if you want to make it to 100 and beyond. But we need to stay away from the poor fats and the obsession about eating beef. Red meat, if eaten too often gives you a higher risk of getting cancer and heart disease. So eat it only once a week at the most, the rest would be chicken, turkey meat or fish. Nothing wrong with a vegetarian meal, let’s say kidney beans or lentils on a day in between. This still gives you protein for your muscles, but spares you a heart attack.

Seven steps to live over 100 years – step 3: Take care of your teeth

Brush your teeth and floss every day. This will control the bacteria in your mouth and prevent leakage into your blood affecting your heart valves. Studies have shown that this prevents heart attacks.

Explanation: When I heard this first about 20 years ago, I found it strange. But the literature is clear: chronic gingivitis is associated with bacteria that grow on the gums and spread into your blood. They can then colonize your heart valves and even the lining of the arteries, particularly where there is already hardening of the arteries (arterial plaque). This can lead to heart valve disease like mitral valve disease or heart attacks.

Seven steps to live over 100 years – step 4: prevention of disease

See your physician right away if there is a new skin lesion or anything that is different on your body. Removal of early cancer and treatment of any early medical condition is always easier to treat than waiting until it is out of control. Particularly with cancer treatment at an early stage, which usually involves only a small surgical procedure, this will reward you with a ripe old age.

Explanation: I learnt this point in general practice. Patients who waited until small problems become big problems were always much worse off than patients who saw me for small problems that we could remedy at an early stage. As mentioned above this is particularly important in cancer cases, as usually stage 1 and 2 of a cancer is curable with surgery. Once you get lymph node metastases and distant metastases, the cancer is much more difficult to treat, if at all. This is a principle that is pretty much true for any disease. The prevention factor is huge. Make use of it!

Seven steps to live over 100 years – step 5: Lifestyle matters

Watch excesses like smoking (cut it out!), alcohol intake, and recreational drugs. Smoking causes heart attacks, strokes, and cancers, which shorten your life. Recreational drugs just interfere with your body chemistry and have side effects. Cut them out, if you cherish growing older than 100. Alcohol needs to be kept at a very low consumption, if you want to preserve your liver, which is your central metabolic organ. If you can’t handle moderation with alcohol consumption, cut it out. No one has died from not consuming alcohol.

Explanation: I have already explained why lifestyle choices matter. The alcohol question is one that will be discussed back and forth for centuries. There are cardiologists who tell you that men should drink 1 to 2 drinks per day and women 1 drink per day and we all live longer, because of prevention of heart disease. The wine industry makes sure that you will hear this cardiology rule. It is true that centenarians often drink one glass of red wine per day. But there are plenty of centenarians who never drank in their life. It is a matter of personal choice.

Seven steps to live over 100 years – step 6: Avoid obesity and diabetes

I did mention to avoid obesity under point 2 above, which is associated with metabolic syndrome and diabetes. Your ideal body mass index should be in the 21 to 22 range. You can achieve this by following the diets I mentioned above. You should cut out sugar and starchy foods.

Explanation: I have followed such a diet since 2001 and my body mass index is between 21 and 22. I grew up in Germany where an emphasis was put on sweets and starchy foods. Needless to say my modified Mediterranean diet deviates from the good old German diet significantly. I find healthy food very tasty.

Seven steps to live over 100 years – step 7: Sleep and hormones

Getting sleep regularly, having an optimistic outlook on life, and having good relationships help to keep the immune system strong and keep your hormones balanced. This in turn will keep you healthy emotionally and physically.

Explanation:

There are two comments I like to make. One is that when you have calm nerves, and your emotions are in balance, your stress hormones are under control. We know that people who are content and easy going live longer. The type A personality is the one who gets a heart attack.

The other point is that hormones have running times. When they start missing, we get menopause or andropause. When we are in our 50’s it is time to have your hormones checked by a knowledgeable health practitioner (naturopath, anti-aging physician). At this point regular physicians are mostly lack education about bioidentical hormone replacement. I mention this as in European studies it has been shown that replacement of missing hormones with bioidentical hormones resulted in more youthful lives. You can extend your life expectancy by 15 years using bioidentical hormones according to Dr. Hertoghe, an endocrinologist in Belgium.

Seven Steps To Live Over 100 Years

Conclusion

People have had a long time fascination about the factors that lead to a healthy age above 100 years. I am suggesting that you concentrate on enjoying your life and keeping toxins out. Engage in some form of exercise or stay active all the time. Adopt a healthy diet. This is where perhaps most people go wrong. They think they can go on pouring junk foods and alcohol down their throats and never get heart disease or cancer. The truth is not quite like that. We do need to adopt a healthy diet like the Mediterranean diet. We also need to limit drinking to a healthy level. Replacing missing hormones with bioidentical ones will prolong your life as well. Given these recommendations, happy journey to 100 and beyond!

Avoid That Heart Attack

Recently Dr. Mark Hyman mentioned a 7-point program to avoid that heart attack. If you follow the recommendations below, chances are that you do not only avoid heart attacks, but also strokes, high blood pressure, diabetes and obesity.

The Potsdam (or EPIC) study has shown that adhering to 4 simple things can reduce

Diabetes by 93%

Heart attacks by 81%

Strokes by 50%

All cancers by 36%.

What were those 4 points?

  1. Not smoking
  2. Exercising 3.5 hours a week
  3. Eating a healthy diet
  4. And maintaining a healthy weight

So with a few more points added it is no wonder that the figures can be even more impressive.

The INTERHEART study

Other studies have also shown the importance of lifestyle changes to improve health outcomes; the INTERHEART study was based on 30,000 people in 52 countries that were followed along. Researchers found that 90 percent of all heart disease could be prevented by simple lifestyle changes.  I have added another point, regular exercise that has been proven to be very effective in preventing many diseases.

So, what are the 8 points that can assure that our health improves?

1.Avoid that heart attack with a colorful, plant-based diet

Your dietary intake is important, because it provides all of the building blocks for your body. You want whole foods that are rich in phytonutrients. Often rainbow colors are mentioned, because the more varied your vegetables look, the more balanced the micronutrients, vitamins and minerals in the food items. Below we will learn that we want to avoid processed foods and hydrogenated fats, but we want to increase fiber and omega-3 fatty acids.

2. Avoid that heart attack by stabilizing your blood sugar

Never eat refined carbs alone, as this goes chases up your blood sugar levels and causes unhealthy insulin reactions. Too much insulin production causes inflammation in the body, which can cause inflammatory bowel disease, arthritis, clogged arteries with heart attacks and strokes and Alzheimer’s disease. You want to balance complex carbs from vegetables with healthy fats and clean protein in every meal. Avoid sugars- no matter whether it is “natural brown” or white sugar and refined carbohydrates. Your pancreas does not differentiate between honey and other sugars, and it will react the same way!

3.Avoid that heart attack by increasing fiber intake

The more fiber you can tolerate, the better. 50 grams would be ideal, but not everybody can tolerate this due to bloating or a queasy stomach. But even if you can add 5 or 10 grams of fiber per day, this is progress. Fiber decreases LDL cholesterol by intervening with the enterohepatic pathway. Fiber is found in nuts, beans, vegetables, seeds and berries that have lower sugar in them. You can also take a fiber supplement directly like psyllium husk.

4.Avoid that heart attack by cutting out processed foods

Processed foods and junk foods are popular as they fill you up fast when you are hungry. But they need to be avoided at all costs. Sodas, juices and diet drinks affect your sugar and fat metabolism. The extra calories that come from sugary drinks are the biggest contributors to diabetes, heart disease and obesity. Even 100% fruit juice is not healthy, because all of the fiber is removed and you are drinking sugar water to which your pancreas reacts by producing extra insulin. As already discussed the extra insulin just causes inflammation.

Homemade lemon juice

May I suggest a homemade lemon juice that you make by squeezing ½ lemon into a glass; add a tiny bit of Stevia for sweetening and sparkling mineral water. This is a healthy drink without sugar. You can drink this as often as you want. Another component of processed food are omega-6 fatty acids. They are in processed foods, because they increase the shelf life in stores. But they cause inflammation in the body unless balanced by omega-3 fatty acids (see below).

5.Avoid that heart attack by increasing omega-3 fatty acids

Fish and seafood provide you with healthy omega-3 fatty acids. Unfortunately not all fish are healthy. Tuna is a predator fish that accumulates a lot of mercury from the polluted oceans. As a result of this it is not on my fish list. I prefer wild salmon. I also take molecularly distilled fish oil, which has omega-3 fatty acids in it. Many processed foods contain only omega-6 fatty acids, because this is the cheapest way to produce them (they are based on vegetable oils). Also avoid soybean oil, which is the most popular oil in the last few decades to foul up the omega-6 to omega-3 ratio.

Omega-6 to omega-3 ratio

This ratio should be 1:1 to 3:1, but many Americans’ omega-6 to omega-3 ratio is 6:1 to 18:1. Omega-6-fatty acids cause arthritis, heart disease and strokes. Instead you want to eat healthy fats like omega-3 fatty acids contained in nuts and fish. You can also add molecularly distilled, high potency omega-3 fatty acids as a supplement to help restore the balance between omega-6 and omega-3 in your food intake.

6.Avoid that heart attack by eliminating all hydrogenated fat

Hydrogenated fat like margarine has been shown to cause accelerated hardening of the arteries, which causes heart attacks and strokes. Read labels and eliminate any food that contains hydrogenated fats. If the label indicates that you are dealing with a product containing ”partially hydrogenated oil”, stay away from it as well! Butter from grass fed cows is a healthy fat. Olive oil and coconut oil are both good cooking oils. Olive oil is also good in salad dressings.

7.Avoid that heart attack by keeping alcohol to a minimum

The problem with alcohol is that it is a cell poison. On the other hand small amounts have been show to reduce heart attacks and strokes (one glass for women, two glasses for men per day). However, due to the cell poison effect even low amounts of alcohol contribute to cancer causation, and as a result of that alcohol remains a problem. If you must consume alcohol limiting the intake to minimal amounts is prudent. Alcohol can cause ovarian cancer in women and prostate cancer in men. In both sexes pancreatic cancer can be caused by alcohol. Higher amounts of alcohol raise inflammation with elevation of blood pressure, heart attacks and strokes. One recommendation: either consume no alcohol or use alcohol in moderation. One glass does not kill you, but several ones may do it over time!

8.Avoid that heart attack by exercising regularly

Regular exercise is yet another factor that can help you to reduce heart attacks, strokes and cancer even further. I added it as point 8, because it is fundamentally such an important preventative factor. Some studies have shown as much as a 50% drop in many diseases simply by introducing regular exercise.

Avoid That Heart Attack

Conclusion

It is all about lifestyle factors. Pay attention to your diet. Add fiber, subtract sugar. Avoid processed foods, omega-6 fatty acids and hydrogenated fat. Have enough omega-3 fatty acids as fish and supplements. Keep alcohol to a minimum. Your benefits from changing these lifestyle factors, result in huge benefits. You are avoiding 90% of diabetes, 80% of heart attacks, 50% of strokes and 35% of cancers.

Prevent Unhealthy Aging

We know that stress can age you prematurely, but what do we need to do to prevent unhealthy aging? This is exactly what this review by cardiologist Dr. Joel Kahn has done. It points out that the right lifestyle makes the difference.

Studies showing how to prevent unhealthy aging

Several studies have shown how to avoid getting heart disease, cancer and diabetes.

2001 Harvard lifestyle study

Kahn reported that in 2001 the Harvard School of Public Health published a study where 84,941 healthy female nurses had been followed who were free of heart disease, cancer and diabetes at baseline. But only 3.4% of the 84,941 women managed to stay healthy after 16 years of the study. The secret? Their body mass index (BMI) was less than 25.0, their diet was high in polyunsaturated fat and fiber, low in trans fat and low in glycemic load, they engaged in regular moderate exercise with a minimum of 30 minutes per day; they did not smoke and they drank ½ an alcoholic drink per day. Their risk to get diabetes was 91% lower than the rest of the study. This shows you how powerful lifestyle choices are; it shows us how to prevent unhealthy aging.

INTERHEART study

In 2004 an international study (the INTERHEART study) reported in the Lancet the lifestyle of 15,152 cases that developed heart attacks in 52 countries with 14,820 controls who did not have heart attacks. The researchers found 9 risk factors that accounted for 90 to 95% of the heart attacks. They were smoking, cholesterol risk ratio elevation, diabetes, high blood pressure, abdominal obesity, stress, low intake of fruit and vegetables, high alcohol intake and lack of physical exercise. Obesity counted as a risk factor when the waist circumference measured more than 35 inches in a woman or more than 40 inches in a man. Lifestyle changes could eliminate all these 9 risks.

2006 Health Professional Study

The 2006 Health Professional Study spanned over 16 years in a group of 40 to 75 year old doctors without a heart attack at baseline. It noted that male doctors who were lacking the 5 heart attack risk factors had 87% less heart attacks than controls without health lifestyles. What were the lifestyle factors? A body mass index (BMI) of less than 25, being a nonsmoker, being physically active for more than 30 minutes a day, having not more than moderate amounts of alcohol intake and having a diet that was more than 40% plant based.

2007 Swedish study

In 2007 a Swedish study reported on 24,000 women after menopause that had no heart attacks initially. After 6 years of follow-up 308 women developed heart attacks. An analysis showed what the risk factors were for those who developed heart attacks. Those who did not have these risk factors reduced their risk of getting a heart attack by 92%. What lifestyle factors were protective? Four factors were identified: a low-risk diet (consisting of high vegetable and high fruit intake, whole grains, legumes, fish and moderate alcohol intake), not smoking, walking or biking 40 minutes daily and a low waist circumference.

2008 Harvard study (follow-up to 2001 study)

In 2008 the Harvard University released a study that was a further follow-up of the Health Professional study with more than 43,000 men and also the Nurses’ Health Study with more than 71,000 women. The question here was what would prevent the development of strokes? The investigators found that in both groups stroke risk reduction by 50% was achievable with the following 5 lifestyle factors: no smoking, keep the BMI below 25, exercise at least 30 minutes daily with moderate activity, don’t exceed a modest alcohol intake and have a diet intake in the top 40% of fruit, vegetables and whole grains. This, too shows us how to prevent unhealthy aging.

2014 study from the Netherlands

A 14 yearlong study from the Netherlands was published in 2014, where almost 18,000 men and women without heart disease at the beginning of the study were followed. More than 600 heart attacks occurred throughout the study. People who stuck to 4 lifestyle habits reduced their heart attack rates by 67%; if they adhered to 5 lifestyle factors they reduced the heart attack rate by 83%. The 4 initial lifestyle factors were: doing an average of 30 minutes of physical activity per day, eating a Mediterranean style diet rich in fruit and vegetables and whole grains, not smoking and having more than one alcoholic drink per month. This gave you a reduced risk of your heart attack rate by 67%. Add one more good habit: sleep 7 or more hours per night on average. This reduces the risk of you getting a heart attack by 83%!

Swedish heart study (more than 20,000 men)

A Swedish heart study with initially more than 20,000 men was going on for 11 years.  The investigators identified 5 lifestyle habits as essential to reduce heart attack rates. Unfortunately only 1% of the study group adopted all 5 lifestyle factors, but they dropped their chance of getting a heart attack or dying of a heart attack by 86%. The lifestyle factors were: a diet rich in fruit and vegetables, legumes, nuts, whole grains and low fat; not smoking, moderate alcohol consumption, thin waistline and more than 40 minutes of physical activity. All of this demonstrates to us how to prevent unhealthy aging.

Preserving health and vitality to prevent unhealthy aging

There is a clear pattern in all of these large studies. A healthy lifestyle preserves your health by keeping your joints and muscles in good working order. When you engage in cardiovascular training every day,  your heart and lungs will work at their best capacity. This keeps your nitric oxide going, which is an important signalling molecule that in turn reduces your blood pressure.

When we remove disabling diseases like strokes and heart attacks and prevent diabetes from developing, life expectancy is increasing. There will be fewer disabilities and less frailty when people remain physically active even in old age. By adhering to good lifestyle habits even Alzheimer’s disease occurs less often.

Conclusion

The studies cited here show how lifestyle factors can make a significant difference in preventing heart attacks and strokes. In the past even doctors ignored the risk of smoking. A few years back conventional medicine negated that lifestyle factors could make a difference. Now we have more studies than we need to prove that this is so. It is more important that we adhere to as many of the lifestyle factors identified in these studies to make a real difference in our lives. We also need to set an example to the next generation and to our peers. Adopting healthy lifestyle factors has to become a cultural habit for society at large. This will help reduce healthcare costs, but most importantly this will help you and me to live longer, healthier lives. It will help us to prevent unhealthy aging.
