Moderate Carb Intake Has The Lowest Mortality

By | diet, exercise, heart attack, lifestyle, Mortality, Nutrition, Stroke

A 25-year long study has shown that a moderate carb intake has the lowest mortality. A comprehensive study from the US has followed more than 15,000 men and women for 25 years. They were between 45-64 years when they entered the study and they were from diverse socioeconomic backgrounds. The authors chose mortality as an end point. Dr. Sara Seidelmann is a clinical and research fellow in cardiovascular medicine from Brigham and Women’s Hospital in Boston. She was the lead author of this study. The research group used food questionnaires and analyzed the carb content in the food. They also determined what percentage of the food composition was of animal origin or plant origin.

Research study finds moderate carb intake has the lowest mortality

The main findings of the study were that less than 40% of carbs in the diet led to an increased death rate with a mortality of between 1.4-fold and 1.8-fold. On the other hand, more than 70% of carbs in the diet also had increased mortality rates of 1.2-fold. The lowest mortality was in the group that consumed a diet where carbs were between 50% and 55%. Dr. Seidelmann explained that in terms of life expectancy the result of the study could be summarized as follows. A 50-year-old person had another 33 years to live when carb intake was in the moderate range. The low-carb person had only another 29 years to live (4 years less than the moderate carb person). The high-carb person lived another 32 years, 1 year less than the moderate carb person.

Plant-derived versus animal-derived fat and protein

The study showed that there was increased longevity when carbohydrates were exchanged for proteins and fats from plant sources. Mortality was 18% less for this group. Conversely, when carbs were replaced for animal-derived fat or protein mortality was 18% more!

Dr. Seidelmann noted that this study was coming from a US based population. In the case of an Asian group they would consume much more carbs on average, but they would replace a lot of the animal fat and protein with fish. Fish is a healthier source of protein and fat than beef or pork.

A moderate carb intake group that used protein and fat from animal sources was compared to plant sources. When protein and fat had the origin from lamb, beef, pork, and chicken the mortality over 25 years was higher. When protein and fat came from vegetables, such as nuts, peanut butter, seeds and whole-grain breads there was a lower mortality rate.

Other studies comparing the effect of animal protein versus plant protein

  1. A 2016 study that had gone on for 49 years was involving 131,342 participants. Animal protein intake showed an association with higher mortality from heart attacks and strokes. 3% of energy from processed red meat was now substituted by an equivalent amount of plant protein. This reduced the all-cause mortality by 34%, for unprocessed red meat by 12% and for egg by 19%.

 

  1. Red meat is cancer-producing. Several studies have shown this. When red meat is digested, cancer-causing substances are released that can be the cause of cancer in the lining of the stomach and the colon. The above link says we should limit red meat consumption to 65 grams (2oz.) per day or 2 servings (130 grams or 4 oz.) 3 to 4 times per week. We should avoid eating more than 455 grams (1 pound) of lean red meat per week.

Triglycerides are an independent risk factor for heart attacks

In this publication evidence is also present that triglycerides are an independent risk factor that can cause heart attacks.

When you eat too many carbs, the body produces the excess you don’t need into triglycerides, and it deposits its subsequently as fat in fatty tissue.  Physical activity burns up some of the triglycerides. But when we eat too much refined sugar and starchy foods, there will be an excess of triglycerides putting our blood vessels and our hearts at risk.

Regular exercise prevents disease and premature deaths

Many studies have shown that regular exercise prevents heart attacks and premature deaths. We even know the mechanism of why this is so. Exercise releases nitric oxide ((NO) from our blood vessels, which widens the arteries. This also prevents high blood pressure. Exercise elevates the protective HDL cholesterol. When regular exercisers were compared to a non-active group they had a 41% lower risk of death. All-cause hospitalizations were down by 21% and cardiac hospitalizations were down 32%.

Discussion

  1. Barry Sears is the inventor of the Zone Diet. I attended a lecture in 2001 at an Anti-Aging Conference in San Diego. Dr. Sears was the keynote speaker at this conference. He stressed that a diet with 55% of complex carbs would be the best diet. It is interesting that Dr. Seidelmann in the study mentioned in beginning of this blog found the same thing. The lowest mortality was in the group that consumed a diet where carbs were between 50% and 55%.
  2. The second point that is important to note is that it matters whether we eat protein derived from animals or from plants. Even small steps help. When we reduce our animal protein intake by only 3% of the energy intake, and replace it by plant protein, there is a significant reduction in mortality.
  3. Exercise is rarely mentioned in relation to diets. But exercise needs to be included every day and you will experience a reduction of cardiac hospitalizations of 32% as mentioned above.
Moderate Carb Intake Has The Lowest Mortality

Moderate Carb Intake Has The Lowest Mortality

Conclusion

A moderate carb intake, as is the case in the Mediterranean diet and in the Zone Diet of Barry Sears, has the lowest mortality rate. Complex carbs (in vegetables) are absorbed much slower. As a result the risk for heart attacks is much lower. The opposite is true for refined carbs from sugar. They cause heart attacks and strokes with premature mortality. Dr. Sara Seidelmann led a study at the Brigham and Women’s Hospital in Boston that lasted 25 years. Less than 40% of carbs in the diet led to an increased death rate with a mortality of between 1.4-fold and 1.8-fold. These diets are paleo-type diets, the Atkins diet and the ketogenic diet. More than 70% of carbs in the diet also had increased mortality rates of 1.2-fold.

The healthiest diet

People who consumed a diet where carbs were between 50% and 55% had the lowest mortality rate (Zone Diet). Another finding of this study, which was confirmed by others is that animal-based protein is unhealthier than plant-based protein. Even replacing 3% of energy from an animal-based diet with plant-derived protein delayed mortality significantly.

If you want to live longer and stay healthy you need to critically evaluate what you eat.

Combatting Aging using Artificial Intelligence

By | Anti-aging medicine, Cancer, Cardiovascular disease, heart attack, Heart Disease, Inflammation, mitochondria, Obesity, Stroke, Weight loss

I found an article dealing with combatting aging using artificial intelligence. It comes from the April 2018 edition of the Life Extension Magazine.  Both of those concepts sound intriguing: “combatting aging”. It would be nice, if this would be a possibility! And “artificial intelligence” (A.I.) sounds mysterious. LifeExtension researchers have partnered up with an A.I. group, called Insilico Medicine.

Why did Life Extension engage in this project? Many people have side effects with the drug metformin, which is an old diabetes drug. It turns out that metformin stimulates anti-aging genes that help to elongate telomeres and also activate genes that prolong lives otherwise. The thought was to find out how exactly metformin protects against age-related disorders. Once researchers located the genes, they may be able to find herbs that can do the same as drugs with less side effects. Often herbs are safer than drugs.

Background regarding metformin

The FDA accepted metformin (trade name Glucophage) as the first-line therapy for type 2 diabetics, particularly if they are overweight or obese.

Side effects include gastrointestinal irritation with vomiting, cramps, diarrhea and flatulence. Even though this drug is not new, research does not fully understand all metabolic effects of metformin.

Promise of metformin as an anti-aging drug

A trial in Great Britain found that metformin has an interesting anti-aging effect. Diabetics on metformin lived longer than a control group of patients without diabetes who were not on metformin. The diabetics lived 15% longer than the controls. Further experiments with human cells and animal experiments showed that metformin is able to stimulate the mitochondria without producing as many free radicals. Free radicals cause inflammation that leads to heart attacks, strokes, Alzheimer’s and cancer. The suggestion is that all of these diseases will be suppressed when the patient is on metformin.

Mimicking the effects of metformin with three herbs

The co-operative research between the Life Extension researchers and Insilico Medicine researchers concentrated on finding data that would replace the beneficial effects of metformin with three herbs stimulating the same life-prolonging targets in human cells. This is not a small task. The following three herbs in combination cover more than 78% of the actions of metformin.

Withaferin A (found in Ashwagandha)

Weight loss

Withaferin A is a component of the life-prolonging herb ashwagandha. This herb is in use in Ayurvedic medicine because of its ant-inflammatory action; it is also anti-diabetic, anti-cancer, anti-obesity and has appetite-regulating activities. An important observation by researchers was that within 21 days of exposing obese mice to withaferin A they lost 23% of their weight. Other mice on the same diet received control solutions and did not lose weight.

Effect on neurodegenerative disease

There is a neurodegenerative condition, called Lou Gehrig disease (=amyotrophic lateral sclerosis). A group of mice that were the subjects of genetic modification to develop Lou Gehrig disease received withaferin A in their food. Compared to controls without withaferin A they had a 39% reduction of damaged proteins in their spinal cords. They also had 60% less loss of motor nerve cells. These are the nerve cells that pass on the electrical signals between the brain, the spinal cord and into the muscles. The life span of these animals that received withaferin A was 5.4% longer than control animals.

Ginsenoside (found in Ginseng)

The structure of ginsenoside is steroid-like. As the name already suggests, it is present in ginseng. The Insilico Medicine team noticed that it affects many of the same age-decelerating pathways like metformin. Ginsenoside prevents damage to the DNA and prevents loss of mitochondria, particularly in the brain and heart. In cancer cases ginsenoside also suppresses cancer stem cells, which slows down cancer growth. All in all ginsenoside reduces inflammatory changes; it also fights neurodegenerative diseases, cardiovascular diseases and cancer.

Gamma linolenic acid (present in borage seed oil)

Gamma linolenic acid (GLA) is a fatty acid. The source of it is the evening primrose plant, black currant oil or borage. The Insilico Medicine researchers found that many pathways that metformin triggers are also responding to GLA. GLA can reduce inflammation, help with adaptation to stress can modulate metabolism and participates in regulation of gene expression. GLA is also part of energy sensing in diabetes and obesity. It also can slow down cancer development.

Discussion

One has to be cognizant of the fact that LifeExtension is in the business of selling herbal supplements. It would be in the company’s interest to find an herbal combination that mimics what Metformin does. They say they have found it; so we are told in the April 2018 article of the LifeExtension magazine. But a 78% overlap of actions when the herbs were compared to metformin is not a 100% overlap.

Conflict of interest

There seems to be a conflict of interest between doing basic research on anti-aging and marketing an anti-aging product. I like to see confirmation of these findings by other independent researchers. I am not too keen to spend $1.40 every day for the rest of my life in the hopes that this herbal concoction would slow down aging. Also to state that this mix of three herbs would do the same as Metformin is a large leap of faith. At this point I am not even ready to swallow metformin just because of one trial in England that showed a beneficial anti-aging effect.

Combatting Aging using Artificial Intelligence

Combatting Aging using Artificial Intelligence

Conclusion

The old dream of finding a pill for anti-aging is alive and well. If you believe this research you are likely to buy this pill and keep on taking it for the rest of your life. But I am not so certain that either swallowing metformin or swallowing this herbal concoction will do what the researchers were hoping for. They have done some basic research with mice and rats. But they tested each of the herbs  separately, and the researchers have then mixed the herbs and claim, that this mix will do what each single herb in isolation has done. We do not know anything about the interaction between these herbs. We do not know whether there will be the same anti-aging results with the mix. All these claims are yet subject to more testing.

Proposed clinical trial

I like to see a human trial where the anti-aging pill of Life Extension is given once per day for several years (let’s say 5 years). After that anti-inflammatory indicators, telomere length and toxicity should be tested in each subject that is part of the study. If trials like this were successful in humans, I would consider buying this new supplement, but not any earlier!

Benefits Of Eating Nuts

By | fiber, food, heart attack, Heart Disease, Nutrition, omega-3 fatty acids, polyunsaturated oil, Stroke

You hear from time to time that there are benefits of eating nuts. But you don’t often see more details about it. I came across an article entitled “Nut lovers rejoice: Your favorite snack protects your heart”. It stressed that nuts prevent heart attacks. I will review some of this information here, but also touch on other aspects.

What nuts contain

Nuts contain fiber, unsaturated fatty acids, protein, vitamin E, folate and many minerals (zinc, potassium, magnesium). These ingredients have their own positive effects on your metabolism. For instance the fiber will lower cholesterol and triglycerides in your blood, which are risk factors for heart attacks. Vitamin E is a powerful antioxidant. Here is a review that shows why eating nuts makes a difference for your health. Despite all of the good that nuts do, you need to keep an eye at the overall quantity of nuts you eat. Nuts can contain up to 80% as oil, even though they are good oils. But the extra calories associated with the oil can make you gain some weight. When you add nuts to your diet you need to subtract some of the lesser quality saturated fats, so that your overall calorie balance does not change.

How do we know that nuts are healthy?

A British study from 2016 did a meta-analysis of people who ate nuts versus people who did not include nuts in their diet. 10 studies showed that eating nuts reduced mortality from all causes by 19%. In 5 studies where cardiovascular mortality was measured, a reduction of 27% was noticeable. Congestive heart disease in 3 studies showed a reduction by 34% when the patients consumed nuts. Stroke mortality was 17% less, as 3 studies showed. This is just an example of a few studies that show how effective supplementation of your diet by a few nuts here and there can be on the general mortality. It especially applies to mortality which is due to heart disease and strokes. Other effects of nut consumption are the reduction of atrial fibrillation, congestive heart failure and abdominal aneurysm (each by 15 to 20%).

Allergic reactions to nuts

A small percentage of people are allergic to various nuts. Nuts can cause a severe asthma attack, if the person has been sensitized to them in the past. They can cause angioneurotic edema in a small portion of people who may have inherited this condition. Tree nut allergies can cause anaphylaxis as is explained in this link.

The right dosage of nuts

This Australian website says that 30 grams of nuts, which is a handful of them would be the right dose per day. This is about 1 ounce per day. By including a variety of nuts your nutritional content will equal out. Some nuts have more calcium (almonds); others have more plant sterols (pistachios) or more fiber (pecans).

How bias can get introduced into medical literature

The Karolinska institute in Sweden analyzed the lifestyle and behavior pattern of nut lovers. Nut lovers were also into other healthy lifestyles: they smoked less than non-nut lovers. Nut lovers were leaner, physically more active and drank less alcohol.

They also ate more fruit and vegetables. Nut-lovers’ blood pressure was lower than the blood pressure of non-nut lovers. And people who consumed nuts on average had better education. Some of these lifestyle patterns can also protect the heart and contribute to less strokes. The researcher must be vigilant to control for the other lifestyle patterns except for the difference in the nut consumption when looking for the effect of nut consumption. If this is not done, there could be confounding, which introduces a bias into the final results.

Combine nut supplements and adopt a healthy lifestyle

This said, you know now about the results of good research. It is best to not be concerned about biases any more. For the average consumer it is important to apply what we know: use nuts regularly (about 30 grams per day, which is a handful). But it would not be a bad idea to adopt some of the other healthy lifestyles that nut eaters tend to have. In other words, exercise regularly, don’t smoke, cut out sugar, drink less alcohol and eat fruit and vegetables regularly. This way you will amplify the health promoting effect of the nut supplements.

Benefits Of Eating Nuts

Benefits Of Eating Nuts

Conclusion

We learnt that nut consumption is healthy. Only a small number of people who are allergic to nuts have to avoid them. The majority of people benefit from incorporating a small amount of nuts into their diet. Research has shown that it lowers mortality in general, lowers cardiovascular mortality and mortality from congestive heart disease. Eating nuts also reduced stroke mortality and lowers the risk of atrial fibrillation. When research is done, confounding factors like healthy lifestyles have to be controlled. But when an individual wants to reduce health risks, it does not harm to use healthy lifestyle factors along with nuts to reduce any risk. It will amplify the healthy effects of eating nuts.

What lowers LDL cholesterol?

By | blood test, Cardiovascular disease, cholesterol, exercise, fish oil, Fitness, food, heart attack, Heart Disease, Inflammation, Nutrition, Smoking, Stroke, Vitamins and supplements

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!

The Benefits Of Drinking Green Tea

By | Anxiety, Cancer, coffee, depression, green tea, heart attack, High Blood Pressure, Inflammation, Stroke

Chances are you heard about the benefits of drinking green tea to reduce heart disease. But the polyphenols of green tea also prevent cancer, depression and cognitive decline.

Green tea lowers cardiovascular mortality

A study in the Chianti region of Tuscany, Italy consisted of 807 men and women aged 65 years and older. They had urine tests for metabolites of green tea in the beginning of the study. The study went on for 12 years. 274 participants died, which was 34% of the total study group. Tests measured the total urinary polyphenol (TUP) concentration in both groups, the survivors and the participants who died. Those participants whose TUP was in the highest tertile of the TUP values had the lowest all-cause mortality. And those participants whose TUP was in the lowest tertile had the highest all-cause mortality. 

High blood pressure and stroke

A Taiwanese study from 2004 examined the blood pressure of 1507 subjects. There were 711 men and 796 women with a recent diagnosis of  high blood pressure. The investigators looked at tea consumption (green tea and oolong tea) and blood pressure reduction. They found that those who drank 120 to 599 mL/day of green tea or oolong tea decreased their blood pressure by 46%. Those who drank more than 600 mL/day of green tea or oolong tea lowered their blood pressure by 65%.

Another meta-study involving 194,965 people and 4378 strokes found that there was a reduction of strokes with increasing tea consumption. Those who drank 3 or 4 cups of green tea or black tea per day were the experimental group. Researchers compared them  to the control group that drank less than one cup of tea per day. The experimental group had a 21% lower risk of getting a stroke than the control group.

Cancer prevention more with black tea than with green tea

A meta-analysis of 18 studies from China showed that green tea and black tea consumption was beneficial for prevention of cardiovascular disease and for cancer prevention. The highest consumption of green tea reduced cardiovascular mortality by 33%. The highest black tea consumption lowered mortality by 12%. Cancer mortality turned out to be different. Green tea did not produce a reduction in mortality, but black tea lowered it by 21%.

Another study, this one from Shanghai, China, points out that there are 15 polyphenols in green tea that likely work on different target areas of the body. They target 200 different genes in humans affecting diabetes, cancer, cardiovascular disease, neurodegenerative disease, muscular disease and inflammation.

Other cancers like prostate and breast cancer benefit from green tea

This study shows evidence that habitual green tea drinkers do prevent prostate cancer and breast cancer to a certain extent.

Another study investigates the effect of tea on health. One of the studies from the same authors have shown that the oxidative damage to cells from cigarette smoking can come out in a urine test. Those smokers who drank 4 cups of tea per day had a 31% decrease in their urinary biomarkers to indicate DNA damage. As DNA damage is often the first step in cancer development, these findings are important to note.

Cognitive effects of green tea consumption in dementia patients

A 2017 review of dietary supplements to improve cognitive impairment pointed out several supplements that will improve cognition. Green tea is one of them, but omega-3 fatty acids (EPA), and docosahexaenoic acid (DHA) are also useful supplements to restore neuronal functioning.

A 2017 study from Basel, Switzerland found that green tea improved memory, reduced anxiety and activated the working memory, which could be made visible on functional MRI scans. These researchers also pointed out that green tea has this effect as a whole, you cannot attribute it to a single constituent. Separate tests of  caffeine or L-Theanine  showed that the beneficial effect was smaller than when green tea as a whole was tested.

2016 study on severe Alzheimer’s patients

This 2016 Iranian study looked at 30 patients with severe Alzheimer’s disease. A baseline assessment was first, and 2 months after taking 4 green tea pills daily another assessment followed. A blood test measured the oxidative stress before and after, so was the antioxidant level from the green tea. The oxidative stress test showed an improvement during the study. The antioxidant level in the blood was higher than before the start of the study. The cognitive function test improved only slightly.

A 2018 study from Singapore looked at the effect of drinking tea (black tea or green tea) regarding symptoms of anxiety or depression. In a group of 614 subjects who were elderly individuals, aged 60 years and above; 59% consumed tea for longer than 15 years. These tea-drinking people were significantly less depressed and significantly less anxious when they underwent psychological tests, compared to non-tea drinkers.

Depression and green tea consumption

There is a 2018 study from South Korea that looked at the link of beverages from 15 studies with depression. 347,691 participants were part  of  these 15 studies, and 20,572 cases of depression developed. Comparing a high consumption of tea or coffee to low consumption, the following statistics were the result: coffee consumption reduced depression by 27%, green tea consumption by 29%.

The Benefits Of Drinking Green Tea

Conclusion

Bioflavonoids are powerful antioxidants. But there are many more substances in green tea and coffee that are all beneficial for our health. One of the studies mentioned identified 15 polyphenols in green tea. But another study said that trying to identify one of the components as more active than the others would be a waste of time. They measured some of the factors by themselves and found that the overall effect was much smaller than green tea as a whole.

Other research has shown that the components of green tea activate several genes. This includes anti-inflammatory effects, prevention of heart attacks and strokes, lowering of blood pressure, anti-cancer effects, improvements of cognitive function, as well as improvement of depression and anxiety. As you can see the effect of green tea is diversified. Don’t hesitate to consume another cup of tea!

Animal Protein Is Bad And Nut Protein Good For You

By | Alzheimer’s disease, Cardiovascular disease, Dementia, Diabetes, diet, heart attack, Heart Disease, Inflammation, Nutrition, olive oil, omega-3 fatty acids, Stroke

Recently a study from California and France showed that animal protein is bad and nut protein good for you. This review goes back to  this original study from April 2, 2018.  Other studies have shown that there is a higher mortality with a meat-based diet.

How the study was done

Researchers followed 81,337 men and women from the Adventist Health Study-2 for a time of over 9.4 years. Between 2002 and 2007 they also researched the diet of the study participants. They used food frequency questionnaires. 2276 cardiovascular deaths occurred during the observation period. The risk for cardiovascular mortality regarding meat protein consumption was 1.61-fold. The cardiovascular risk for the nuts and seeds protein consumption group was 0.60. This means that the meat-consumers had a 61% higher heart attack and stroke rate. In comparison, the group that consumed nuts and seeds had 40% less heart attacks and strokes than people on a regular diet.

Discussion of the study

This study is rather large and went on for a long time (9.4 years). This gives the study great statistical power. The message from the study is quite clear. The more animal protein you eat, the higher your risk will be to succumb to cardiovascular disease. Having a heart attack or stroke prematurely will shorten your lifespan. In contrast, those whose protein source comes mainly from nuts and seeds are better off. They have a 40% lower probability to die from heart attacks or strokes.

Other studies regarding “animal protein is bad and nut protein good for you”

Diabetes caused by red meats, processed meats, whole grains and sugar-sweetened beverages

A European study was analyzing risk foods that can lead to diabetes. https://www.ncbi.nlm.nih.gov/pubmed/28397016 The publication of the study was  in May 2017. Red meats, processed meats, whole grains and sugar-sweetened beverages caused a 3-fold higher risk to develop type 2 diabetes. This was compared to people avoiding those foods. Study participants consuming legumes and nuts had a low risk of developing diabetes. In between was a moderate risk group who ate refined grains, eggs, fruit, vegetables, dairy and fish. Consumption of risk-decreasing foods resulted in a 42% reduction of diabetes.

Foods that caused heart attacks and strokes

A March 7, 2017 study from Boston analyzed the key foods that cause increased mortality.  Intake of high sodium, highly processed meats, sugar-sweetened beverages and also unprocessed meats caused heart attacks and strokes. In addition, a lack of nuts/seeds, low consumption of seafood omega-3 fats, low vegetable and low fruit consumption also caused mortality from heart attacks and strokes.

Nuts reducing inflammatory biomarkers

A September 2016 study from Brigham and Women’s Hospital, Boston, MA looked at the correlation of nut consumption and an anti-inflammatory response. 5013 patients from the Nurses’ Health Study (NHS) and Health Professionals Follow-Up Study received food consumption questionnaires.

Research used two parameters for measuring inflammatory biomarkers: on the one hand blood tests checked the C-reactive protein (CRP), on the other hand they observed interleukin 6. Interestingly there was a correlation between nut consumption and decrease of inflammatory markers. When 5 or more helpings of nuts per week were part of the dietary habits, there was a 20% reduction in the CRP value and a 14% reduction of interleukin 6 , which was a difference to those persons who never consumed nuts. This is significant, because we know that inflammation of the lining of the arteries is a cause for high blood pressure, heart attacks and strokes. Inflammation of the arteries can also cause type 2 diabetes.

Dietary intake among US adults, 1999-2012

This June 2016 study has the title ”Dietary Intake Among US Adults, 1999-2012”. Comparisons were made between a previous dietary study of 1999-2000 and now. The investigators noted some improvements in dietary habits. The persons consumed more whole grains and nuts or seeds. They also had slightly increased fish and shellfish intake. On the other hand, consumption of sugar-sweetened beverages had decreased. But other food components like salt intake, total fruits and vegetables, processed meats and saturated fat had not changed. There was an increased consumption of whole fruit and a decrease of 100% fruit juice (which is sugar laden). Unfortunately there was also some bad news: low-income Americans still have poor food intake, so do non-Hispanic blacks or Mexican American adults.

Mediterranean diet can prevent cognitive decline

A July 2016 review shows that a Mediterranean diet can prevent cognitive decline like dementia and Alzheimer’s disease. In this overview the authors have collected evidence showing that adherence to a Mediterranean diet does indeed prevent cognitive decline. The Mediterranean diet consisted of intake of fruit, fish, vegetables and less consumption of sugar, red meat and dairy. The researchers found that the incidence of cancer, strokes, heart attacks and diabetes were all lower, as was dementia. They pointed out that MRI studies have revealed that the brain volume showed a reduction by 5% per decade after the age of 40. From the third to the 8th decade of our lives the short-term memory can show a reduction of about 50%.

Deterioration of general health related to cognitive decline

The authors point out that the combination of heart disease, stroke and diabetes are often an indication that the person’s overall health is declining. Cognitive decline will soon follow, when physical decline is evident. What people often do not realize is that all of these conditions are related to decades of poor diets. Change the diet to a Mediterranean diet, and your heart health will improve; also a stroke and diabetes may be prevented. The interesting observation is that often cognitive functioning also improves. This makes sense: if the brain circulation improves, oxygen and nutrients can reach the brain cells again and brain function can now improve.

Animal Protein Is Bad And Nut Protein Good For You

Animal Protein Is Bad And Nut Protein Good For You

Conclusion

I mentioned a recent publication, which stated that animal protein is bad and nut protein good for you. When I looked at other publications I found this confirmed. Finally I reviewed a study that investigated the use of the Mediterranean diet to improve cognitive function. It became apparent that physical illnesses, like heart attacks, strokes and diabetes, have also a connection to a loss of cognitive function in older age. It may point to a general aging of the lining of the arteries. An anti-inflammatory diet, like the Mediterranean diet, has the potential to improve the lining of the arteries. This leads to a reduction of medical problems like heart disease and diabetes. In addition it can also reverse cognitive decline. The switch to a Mediterranean diet is not dramatic! It can, however, dramatically improve your overall health and wellbeing as you age.

3 Cups Of Coffee Stop Clogged Arteries

By | coffee, heart attack, Heart Disease, Mortality, Stroke

There is a new coffee study that says 3 cups of coffee stop clogged arteries. The study appeared in the Journal of the American Heart Association on March 24, 2018. It was part of the cross sectional Brazilian Longitudinal Study of Adult Health. This study took place from August 2008 to December 2010. It followed 15,105 civil servants, aged 35 to 74 years. They were living in 6 Brazilian cities (Belo Horizonte, Porto Alegre, Rio de Janeiro, Salvador, São Paulo, and Vitoria). The final study sample comprised 4426 individuals who underwent CAC measurements.

CAC score

CAC stands for “coronary artery calcium”. Other tests in the past have shown that CAC is a very sensitive test that quantitates the calcification status of coronary arteries. The CAC score is also known as Agatston score. It also predicts how likely it is that a person with a high CAC count will develop a heart attack down the road. A score of 100 or less is considered to be a low risk for developing a heart attack later in life. If the score is between 100 and 400, it is a moderate risk. A score of more than 400 ranks as a high risk to develop a heart attack.

Study design

Upon entering the study the participants had an extensive entrance exam and interview. Part of this was a nutritional and lifestyle questionnaire. This told the examiners whether the patients were smokers or not. Their age ranged between 35 and 74 years. Participants took a CAC test. 4426 individuals who underwent CAC measurements became part of the study. The participants’ blood pressure and body weight were additional measurements.

Results of the study

There was a negative correlation between the amount of coffee consumed on a daily basis and the CAC score. Specifically, the following observation emerged regarding daily coffee consumption and the risk of a higher than 100 CAC score.

  • Less than 1 cup per day: odds ratio 0.85
  • 1 to 3 cups per day: odds ratio 0.73
  • More than 3 cups per day: odds ratio 0.33

These results show clearly that there is an inverse relationship between coffee consumption and risk of developing coronary artery hardening. Those who consume 3 or more cups of coffee have a lower coronary artery disease risk.

The risk to develop coronary artery calcification in coffee drinkers (3 or more cups) is 67% lower. The comparison group are non-coffee drinkers.

Discussion of the results

The research paper from Brazil compares their results with many other research facilities and concludes that others had very similar conclusions. For instance, a 2014 publication pointed out that consuming more than 5 cups of coffee per day had no association with heart disease and did not cause any increased mortality.

The 2015–2020 Dietary Guidelines for Americans recommends consuming 3 to 5 cups of coffee per day, which reduces the risk of getting diabetes type 2 or cardiovascular disease.

Korean study using CAC scores

One other relevant Korean study that involved 25,138 participants is also of note. The participants consumed 3 to 5 cups of coffee per day. They also underwent CAC tests. The coffee drinkers had a 41% lesser prevalence of CAC score in comparison to non-coffee consuming controls. The authors of the present study said that the Korean study was comparable to their own findings.

Comparison of study to previous literature

Mortality data and coffee consumption

In a large Harvard study that I discussed on Nov. 18, 2017 the end point was mortality data. There too, was a dose response curve. With 3 to 5 cups of decaffeinated or regular coffee there was a reduction of death rates by 15%. Less coffee consumption produced less reduction of mortality.

Stroke data and coffee consumption

In another review on March 4, 2013 I reviewed a 10-yer study that looked at the effect of 1 to 2 cups of coffee per day in 32,600 women. There was a 25-32% reduction of strokes compared to non-coffee or tea consuming controls. I also reviewed a Finnish study that consisted of 29,133 smokers (smoking 5 cigarettes a day) aged 50 to 69 who were stroke free when entering the study. It ended in 1993 and the study had lasted for at least 5 years. Drinking two cups of black tea or 8 cups of coffee reduced the stroke risk by 21 to 23%.

Stroke mortality and coffee consumption

In the Annals of Internal Medicine (June 17, 2008) researchers have found that coffee consumption can be beneficial to reduce stroke mortality. A study using the data from 41,736 male and 86,214 female subjects is quite informative. Researchers followed these people over 18 years in the male group and over 24 years in the female group. The risk of all-cause mortality decreased significantly with increasing coffee consumption in the male as well as in the female group. Men had a relative risk reduction of 20% in comparison to those with the lowest level of coffee consumption. Women with intermediate to high consumption of coffee had a relative risk reduction of 10% to 30 % when compared to the group that drank less than 1 cup of coffee per day. The end point here was risk of death from stroke.

3 Cups Of Coffee Stop Clogged Arteries

3 Cups Of Coffee Stop Clogged Arteries

Conclusion

Coffee has a number of anti-oxidant bioflavonoids that help increase survival. The main study reviewed measured the effects of coffee consumption by calcium scores of the coronary arteries. This is a specific way to look at the relative risk to come down with a heart attack in the future. Other ways to measure the beneficial effect of coffee are mortality as the end point, stroke or stroke mortality. I have reviewed some studies that used all of these end points. It is interesting to observe that consumption of 3 to 5 cups of coffee has such a beneficial effect. It does not matter whether it is regular or decaffeinated coffee. Both have the identical effect. This has been shown by a recent Harvard study.

Coffee and tea make you live longer

Coffee keeps the arteries open for longer, if we consume 3 to 5 cups of coffee per day. This allows our brain to think longer and allows our heart to beat for many more years. It is time to stop the research and to apply what was found: 3 to 5 cups of coffee per day. If tea is what you prefer, you are in luck. Everything I said about coffee also applies for green and black tea. There is one word of caution. Using copious amounts of sugar in your coffee or tea will most likely cancel some or all of the benefits. Cream and sugar-laced Frappuccino or Chai Lattes are calorie bombs and not conducive to good health. I use stevia instead of sugar to sweeten my coffee.

Prevent Plugged Arteries

By | Cardiovascular disease, cholesterol, Diabetes, diet, exercise, fish oil, Fitness, food, heart attack, High Blood Pressure, Inflammation, lifestyle, Mortality, Nutrition, Obesity, olive oil, omega-3 fatty acids, Prevention, Processed food, Stroke, sugar

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.

What Causes Premature Aging?

By | alcohol, Anti-aging medicine, Dementia, Diabetes, diet, Drugs, exercise, heart attack, Prevention, Smoking, Stroke, testosterone, thyroid disease

Some people look 10 years older than their stated age, and we often wonder: what causes premature aging? Accelerated or premature aging can have a multitude of underlying causes. I will list a few here:

1. Weakening hormones

Men go through andropause at around the age of 60 to 65 and women go through menopause around the age of 55 to 65. In both males and females it is the sex hormones that are missing around that age. If hormones replacement follows fairly quickly with bioidentical hormones, this will not affect the visual appearance that much. In contrast, if bioidentical hormones are not the therapeutic choice for  hormone replacement, but synthetic ones, the hormones are not in balance, as synthetic hormones do not restore the hormonal balance. Nothing is gained, as the person will still age prematurely.

Synthetic versus bioidentical hormone replacement

In addition the synthetic hormones will cause heart attacks, strokes, clots, and cancer. Prescriptions for synthetic hormones are often the cause that the aging patient population gets these serious complications. Frequently physicians insist on using synthetic hormones from a “reputable” drug company to replace missing hormones. The reason this does not work is that a male has testosterone receptors. They need to be stimulated by bioidentical testosterone to restore all of his missing functions. Also, the same is true in menopausal females who need stimulation of their estrogen receptors and progesterone receptors. Consequently, only bioidentical hormones will return a postmenopausal woman back to normal. There is a perfect fit between the bioidentical replacement hormones and her hormone receptors. Using synthetic hormones is like trying to unlock a door with a key that does not have a perfect fit: you damage the lock!

2. Missing human growth hormone (HGH) and thyroid hormones

These hormones have a special place in aging.

Human growth hormone deficiency

First, HGH production is running out in many people at age 60. A person with HGH deficiency will have lower muscle mass and strength. Other symptoms are dry and thin skin, particularly at the back of the hands. Men are balding, and they loose interest in sex. There are difficulties concentrating and they may have “senior moments”, which are memory lapses. Often they are prone to depression and anxiety. A blood test will frequently show elevated triglycerides. A blood test (IGF-1) and a urine test exist which make it possible to look for HGH metabolites to assess whether a 40, 50 or 60 year-old person is producing enough HGH. Many may need replacement of HGH. This is administered by injection through a tiny needle into the skin, similar to a diabetic injecting insulin. This will bring back what was missing due to HGH deficiency.

Thyroid hormone deficiency

Thyroid hormones (T3 and T4) are other important factors that could make you look older prematurely. Your hair is getting thinner; your skin turns dry and pale. The nails may be getting brittle. When the outside half of the eyebrows is very thin or missing, this can be a sign of hypothyroidism. In a similar vein the skin in the face may be puffed up due to swelling of the layers under the skin (myxedema). It is important to diagnose hypothyroidism, which is common in the aging population. The physician needs to order a blood tests (TSH, T3 and T4). If TSH is above the upper limit, your physician needs to replace both T3 and T4 by tablets (I prefer Armour as the T3 and T4 is balanced).

3. Smoking

The lining of the airways absorb cigarette smoke. The chemicals circulate around in the blood and lead to aging of the skin. Chronic cigarette smoke exposure also melts away the subcutaneous tissue. The end result is a haggard look. The natural glow disappears from the skin and because of carbon monoxide binding to hemoglobin the skin color looks more greyish. In addition the blood vessels are narrowing or clogging. This means that the body cannot absorb nutrients as well, and cells are starving. There is only one remedy for this: quit smoking!

4. Overexposure to ultraviolet light

The radiation of UV light can penetrate deep into and under the skin. This makes the subcutaneous fat melt away. The largest UV exposure is in the facial area. As a result we see aging there. The end result is a sagging appearance of the face. This link has an image of a woman before and after a non-surgical facelift with stem cells and fatty tissue: Stem Cell Treatments That Are Currently Available – Medical Articles by Dr. Ray

In a surgical procedure the physician harvests mesenchymal stem cells from fatty tissue by liposuction. A cell separator separates the mesenchymal stem cells, the connective tissue and the fat cells. The connective tissue is discarded. Mesenchymal stem cells and fat cells are mixed and injected into the thinned subcutaneous fatty tissue until the person’s younger facial contour is back to normal. Typically this will last for 10 years or more.

5. Drugs and alcohol abuse

Both can lead to malnutrition with weight loss and loss of subcutaneous fatty tissue, which causes sagging breasts in women. In men “beer tits” are common. The reason for this is estrogen accumulation, as alcohol interferes with the elimination of estrogen in the liver. Alcohol is a general cell poison. It causes all of the cells to age prematurely. The more alcohol you drink, the faster you age. The skin develops wrinkles, loss of elasticity and collagen, redness and puffiness. In other words chronic alcohol abuse ages you prematurely. The only remedy for this is to quit drinking. Some of your skin vitality may come back. Our body has an amazing capability to heal itself!

6. Medical illnesses

Many medical illnesses like diabetes, mental illness (depression and schizophrenia), multiple sclerosis, inflammatory bowel disease; cancer and others make you look a lot older very fast.

I will briefly explain the reasons for this.

  • Diabetes

With diabetes type 2 the pancreas releases too much insulin after a meal with starches and sugar; think about a sweet muffin or a toast with jam. The extra insulin causes inflammation. This stimulates enzymes that break down elastin and collagen, leading to wrinkles and sagging skin.

  • Mental illness like depression and schizophrenia

We know from studies that depression leads to shortening of telomeres. This in turn causes cell death in the most rapidly dividing cells like in the skin and hair follicles. The end result is prematurely aged hair and skin. Schizophrenia also leads to premature shortening of the telomeres, which causes premature aging, mitochondrial dysfunction, inflammation and oxidative stress. The end result is that the person looks older than what their chronological age is.

  • Multiple sclerosis

It is sometimes difficult to discern in patients with MS what is normal aging and what is aging from the disease. This link gives some background on this. Many MS patients are anxious, and anxiety and stress by itself also leads to premature aging.

  • Inflammatory bowel disease

The chronic inflammation of either ulcerative colitis or Crohn’s disease can lead to premature aging. High doses of vitamin D3 and molecularly distilled fish oil can be useful to help treat the inflammation. Probiotics are also important to restore the bowel flora.

  • Cancer

Cancer leads to cachexia (excessive weight loss). There is also excessive inflammation, which leads to accelerated aging. The inflammation causes increased oxidative stress. This leads to tissue damage and DNA damage, which makes all cells more vulnerable to develop other cancers. Oxidative stress can substantially accelerate telomere shortening. As a result skin can become saggy, wrinkles develop and the person looks prematurely aged.

7. A chronic lack of physical activity

People who never exercise tend to get overweight and eventually obese. This leads to premature aging. Exercise would elongate telomeres, but inactivity shortens them. Obesity leads to increased oxidative stress and to DNA damage. Obesity also shortens telomeres. All of this leads to premature aging.

What Causes Premature Aging?

What Causes Premature Aging?

Conclusion

These are only a few examples of causes of accelerated aging. The key is to stick to a healthy, balanced diet (like the Mediterranean diet) and exercise regularly. Stop smoking (if you do), don’t take street drugs, and make sure you get enough sleep. Getting enough sleep helps your hormones regenerate overnight. The sympathetic overdrive from your daily activities is counterbalanced by the parasympathetic activities during sleep that causes relaxation. For hormone replacement you may have to see an anti-aging physician, a naturopath or integrative medicine physician. This may be your only chance to address any hormonal deficiencies. Conventional medicine does a very poor job of HRT (hormone replacement therapy) with synthetic hormones. Conventional practitioners want to treat you with synthetic hormones that will make you sick. Hormones for replacement have to be bioidentical! This way you will live 10 to 15 years longer, look younger and stay healthy.

Fasting Mimicking Diet

By | autoimmune disease, Cancer, Diabetes, diet, headache, heart attack, High Blood Pressure, immune system, Inflammation, Multiple sclerosis, Stroke, telomeres

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

Fasting mimicking diet relevant in humans

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

Clinical Application of fasting mimicking diet in cardiovascular health

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

How does the fasting mimicking diet work?

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

Alternative way to make your own 800 calorie food at home

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

Effect of the fasting mimicking diet on the metabolism

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

Clinical observations

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

Inflammation reduced, autoimmune diseases improved

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

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

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

Clinical applications of fasting mimicking diet

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

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

Maintaining the achievements of the fasting mimicking diet

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

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

Conclusion

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

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

A healthier and longer life

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

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