There is an article in a CNN report talking about the foods that are killing us. This review is based on an article in the Lancet. The Lancet study was based on a global review of eating habits in 195 countries. The question in the study was which of 15 food items caused the diseases that killed people. The answer was surprising. There are either omissions or unhealthy components of foods that kill us. Here is a list of 12 food groups that are problematical.

A dozen foods that were found to be problematical in the global review

  • Diet high in sodium (4 grams per day, which is 86% above the optimal level)
  • Low intake of whole grains (only 23% of optimal levels)
  • Low fruit intake
  • Diet high in trans fatty acids
  • Low omega-3 fatty acid diet (due to low intake of sea food)
  • Diet low in calcium
  • Diet low in fiber
  • High intake of sugar beverages or sugary foods (49 grams of sugar per day)
  • Processed meat intake too high (4 grams per day, 90% more than optimal)
  • Red meat consumption too high (27 grams per day, 18% higher than optimal)
  • Nut and seed intake too low (only consuming 12% of desired amount)
  • Diet low in milk (16% of desired amount)

Each of these components or several of them in combination create deficiencies in us or overburden us to the point where we can get sick and disabled.

Different countries have different eating habits

Globally there were 11 million deaths found in 2017 and 255 million years of disability because of various dietary inadequacies.

Here is the lineup of the leading causes of death:

  • cardiovascular disease with 10 million deaths and 207 million years of disability.
  • Cancers caused 913,090 deaths and 20 million years of disability.
  • Type 2 diabetes caused 338,714 deaths and 24 million years of disability.

This was broken down into statistics for each of the contributory countries. Here I am only citing some pertinent data that shows the importance of balanced meals for a healthy life expectancy.

Different death rates in various countries

There were big differences in terms of cardiovascular disease deaths according to various regions. Central Asia had the highest death rate with 613 deaths per 100,000 people per year. In contrast the high-income Asia Pacific group had only a cardiovascular death rate of 68 per 100,000 people per year.

Cancer deaths were highest in East Asia with 41 deaths per 100,000 people. The lowest cancer rate was found in North Africa and the Middle East with 9 deaths per 100,000 people.

Among the 20 most populous countries Egypt had the highest diet-related deaths, namely 552 deaths per 100,000 people. On the other hand Japan had the lowest of all diet related deaths with 97 deaths per 100,000 people. 

Some highlights how unhealthy foods kill us

Globally people only eat 12% of the desirable amount of nuts and seeds. They only drink 13% of what they should consume in terms of milk. People worldwide eat 23% of the desirable amount of whole grains.

Nuts and seeds contain mono- and polyunsaturated fats and omega-3 fatty acids, which lower your risk of getting heart attacks and strokes.

Milk is a good source of calcium, protein, minerals and vitamins. However, milk, yogurt or cheese should be consumed as low fat varieties. Alternatively people who do not consume milk should look for protein carriers such as soy milk or pea milk.

If you eat nuts and vegetables you can largely compensate for low milk consumption. If you don’t get enough whole grains, you are missing a whole lot of nutrients. This makes you more vulnerable of getting cardiovascular disease, hypertension, type 2 diabetes, colon cancer, and obesity.

Other unhealthy foods can kill us

The WHO has labelled red meat and processed meat as being carcinogenic

Studies clearly showed a higher than normal rate of colorectal cancer in those who consumed larger amounts of red meat and/or sausages.

Sugar overconsumption

Sugar overconsumption leads to a variety of conditions. Weight gain with the development of obesity and type 2 diabetes are common when you eat too much sugar. But even cancer like colorectal cancer and pancreatic cancer is more common in people who overindulge in sugar or sugary drinks. Sugar consumption raises your triglyceride and LDL level. This will eventually lead to hardening of the arteries, heart attacks and strokes.

Gout develops with purine containing foods

Gout can be caused by consuming a lot of red meat combined with copious amounts of beer. This is how royalty in the Middle Ages suffered from gout attacks. Gout had the nickname of “Disease of the affluent.” Both beer and red meat contain a lot of purines, which the kidneys cannot handle. The uric acid crystals that precipitate around joints cause excruciating pains.

 What the global health study showed

Researchers of the global health study stated that improving the diet habits could potentially eliminate 1 in 5 deaths globally. Dietary risks for major diseases like heart attacks, strokes and cancer are independent from sex, age and socioeconomic status.

Three dietary factors stood out: too much salt, too little fruit and too little whole grain. These three items were responsible for 50% of diet-related deaths and 66% of “disability-adjusted life years”. The authors used this expression to describe how years of disability had their root in diet deficits (e.g. too little fruit) or overdoses of unhealthy food components (e.g. salt).

The leading dietary risk factors are too much salt, low whole grain, low fruit consumption, low vegetable intake and low omega-3 fatty acid consumption. On top of that come the previously established risks due to sugar overconsumption, excessive fat intake and consumption of red meat and processed meat.

Discussion of the meaning of these results

Deaths from heart attacks and strokes

We know for some time that high sugar and high starchy food intake cause elevated triglycerides and elevated LDL cholesterol. This leads to hardening of the arteries and eventually to strokes and heart attacks.

High sodium intake

Sodium intake of more than 2300 mg per day is considered high and can cause high blood pressure. heart attacks, strokes and aneurysms.

Eating not enough fruit

If you eat too little fruit, your system does not get enough vitamin C and other vitamins. Heart disease, cancer and anemia could develop from that.

Eating not enough vegetables

People who do not eat enough vegetables do not have enough antioxidants that protect them from free radicals. Free radicals are unstable chemicals that attack cells and DNA. Mutated cells can cause cancer. If you eat too little vegetables, you are at a higher risk of getting cancer. But there is another aspect of vegetables: phytonutrients protect from hardening of the arteries and blockages of heart and brain vessels. When someone does not eat enough vegetables, the risk for heart attacks and strokes is higher. Eating vegetables also protects you from diabetes and keeps the blood sugar more stable.

Not eating enough whole grain

Whole grain was identified as missing in a lot of people’s diet. When you incorporate whole grains into your food, you reduce the risk of cardiovascular disease, hypertension, type 2 diabetes, colon cancer, and obesity.

There are vitamins, minerals, dietary fiber and lignans in whole grain. Other nutrients are beta-glucan, several phytochemicals, phytosterols, phytin, and sphingolipids. All of these are necessary to maintain good health.

Low omega-3 fatty acid consumption

Omega-3 fatty acids are important for healthy skin, brain development (neurodevelopment of children) and prevention of heart attacks. Omega-3 fatty acids reduce the risk of cancer because of their anti-inflammatory action and inhibition of cell growth factors. In one study rectal cancer showed a 21% reduction comparing the highest omega-3 fatty acid intake to the lowest intake of omega-3 fatty acids. Colon cancer showed no effect to omega-3 consumption, but breast cancer showed a reduction with omega-3 fatty acid supplementation. Researchers showed that omega-3 fatty acid supplementation can slow down dementia and Alzheimer’s disease. Protein deposits called amyloids were found less in the brain of patients with omega-3 fatty acid supplementation; in addition the brain volume was preserved more with the omega-3 supplement. Low omega-3 fatty acid consumption also has a detrimental effect on macular degeneration of the eyes and on joint pains of rheumatoid arthritis patients.

Conclusion

I have reviewed a global health study that described various risks that led to deaths from different diseases. It was noticeable that death and disability rates varied significantly according to different countries. The authors also looked into food habits and could pinpoint certain food deficiencies that caused diseases that prematurely disabled or killed people. I have described the various one-sided food habits that led to specific diseases.

What we should all learn from this complicated study is that we all can strive to eat more balanced meals. You want to eat a low sodium diet, eat enough fruit and vegetables, to which you add some nuts. Eat enough whole grains and add omega-3 fatty acids. This way the risk of getting cancer, cardiovascular diseases or other problems can be significantly reduced.

Measuring Your Heart Function

By | Anti-aging medicine, Fitness, heart attack, Heart Disease, Nutrition, Prevention, Stroke

Recently I came across a book by Dr. Steven Masley, cardiologist (fellow of the American Heart Association, see Ref.1). The heart’s function is to pump your blood reliably all your life. It is a complicated organ, but it works well, if we treat it well. Western medicine has taught us that with complicated machinery and tests we can assess how the heart is doing. But until recently there was no reliable easier way to assess our cardiac health function. The purpose of this blog is to summarize a three-pronged approach to measure your heart and blood vessel health. It is described in detail in Ref.1, but I doubt that many people have yet read this important reference book. It is also important to FIRST see your doctor whether you are able to do the Bruce protocol (treadmill test, the third component below). If you neglect to be cleared by your doctor you run the risk of possibly getting angina pains or getting a heart attack.

1. Carotid IMT or carotid intimal-medial thickness test: You measure the degree to which there is hardening of the coronary arteries indirectly by measuring the thickness of the lining of the carotid arteries (carotid IMT or carotid intimal-medial thickness test). Dr. Masley has showed over a period of 10 years and more in many patients at his Health Center that there is a close correlation between the degree of coronary artery hardening and the degree of hardening of the carotid arteries. He stated that his research has shown that “90% of the time, the carotid arteries, the coronary arteries, and even the arteries of your legs all grow plaque at the same time”. The gold standard for checking the condition of your coronary arteries is a heart catheterization as Dr. Masley explains (page 58). But he adds: “IMT testing should be the new gold standard for cardiovascular plaque testing. However, this is not yet the case. Despite its usefulness, 95% of doctors are not ordering this screening test for their patients. You can rest assured that this is a situation I am to change“.

2. A detailed lipid analysis called the VAP test: A detailed laboratory test analyzing your lipid fractions (LDL, HDL, total cholesterol and VAP test). The buoyant HDL fraction, called HDL2 is the key to having a low risk for hardening of the arteries. HDL2 is large, fluffy and is designed to remove garbage from within the lining of the arteries. Also, the cholesterol ratio is another measurement for a low risk for hardening of the arteries when it is less than 3.0. The first two tests assess how much hardening of the arteries there is present and when they are normal, there is a relative reassurance that nothing drastic (like a heart attack or stroke) should happen within the next 10 years provided you keep up a regular exercise program and healthy food intake.

3. Bruce protocol (Treadmill test): The Bruce protocol (treadmill test) is often done by a cardiologists, but can also be done through many gyms, where a trainer with experience in exercise physiology will do it. This functional test measuring cardiac output has been developed many decades back and has withstood the test of time. Here is an overview what this is. As the slope of a treadmill and the speed of the belt are increased, the heart needs to do more work to maintain blood flow to your extremities and vital organs. The trainer or exercise physiologist measures the response of the heart activity in relation to the increase of the exercise load. A complicated formula allows calculating how much your maximal cardiac output is. This test has several variations and can be complicated to understand. Essentially, the higher the numbers you can create, the better. Here is a table with various results of the VaO2max from Bruce protocols and how they are interpreted.

4. Treating abnormalities found with the three basic tests: These are the necessary tools that tell you where you are in regard to your heart function. People with heart failure should not do this third test, because their heart muscle is too weak to sustain this and they would get heart failure meaning that blood gets backed up into the lungs and there could be severe breathing problems leading to a lack of oxygen (anoxia) in the heart tissue, which in turn can cause irregular heart beats (fibrillation of the heart muscle) and a heart attack. Assume that the first two tests were within the normal limit for your age, then the Bruce protocol would give you the maximum heart output at the peak level of your treadmill test. At this point you are measuring directly the cardiac output (in other words what your heart is capable of pumping for you in a certain time unit). This measurement is what physicians call the VaO2 max  or maximal oxygen consumption. This is the best index for maximal heart capacity. If your levels are higher than normal, you have extra reserves with respect to your heart as a pump for times when you need it. If this latter tolerance test shows poor results, it usually means that you were inactive and you would benefit from an exercise program. If the first test shows hardening of the arteries more than is appropriate for your age, you would need to look at your eating habits. At the same time often the VAT values and the cholesterol ratio is off meaning that you are eating the wrong foods and it shows in your blood test results.

5. Advise regarding diet, exercise and relaxation: Dr. Masley’s book has several sections that explain what needs to be done when things are not normal. For instance, the author does not mince words when it comes to eating the right fats and cutting out sugar and starchy foods. For instance on page 199 there is a neat table that lists the fiber content of different foods. We need more fiber to slow down the absorption of sugary substances, which will minimize the insulin response following a meal. Dr. Masley also mentions that omega-3-fatty acids from fish and good seafood choices will balance the omega-6-fatty acids that would lead towards the arachidonic acid pathway, which causes arthritis, inflammation and cancer. There are many more dietary recommendations, too numerous to repeat them all here. Suffice it to say that molecularly distilled omega-3 fish oil, vitamin D 1,500 to 3000 Units daily, and magnesium supplements are all good for you heart. Vitamin K2 gets calcium out of your blood vessels and into the bone (100 micrograms per day). Other worthwhile supplements mentioned in the book are CoQ-10 (50 to 200 mg twice per day), but it would be wise to have blood levels drawn, which should be above 2.5mcg/ml to which the CoQ-10 intake could be titrated. Curcumin and Resveratrol are also recommended. Most of all, it seems that regular physical exercise such as a balanced gym program is the single most effective way to reverse hardening of the arteries as measured by the carotid IMT testing.

Conclusion: Times have changed. It used to be thought that our lives were following a one-way street downwards. During periods of malnutrition, lack of exercise, being sessile and abusing alcohol and drugs this may well be the case. However, we now know that this is reversible. Change to healthier food, start smoothies with organic vegetables in a mixer, get going and walk. Jog or use a gym to get regular exercise. Physical exercise reverses the fat deposits inside the lining of the arteries. The HDL-2 fraction rises and helps counteract the elevated LDL cholesterol. Even the mood of the person who exercises regularly becomes more stabilized. Using these simpler three tests the physicians will not need the more complicated Thallium heart scans, heart catheterization etc. These three tests described above are well worth being done every two years, so that you can monitor what’s going on with your heart and blood vessels in general. What questions do you have? You could ask them below.

Nuts To Bust Gallstones Says Harvard

By | Gastrointestinal Disease, Nutrition, Prevention

Gallbladder problems rank fairly high among health problems in Canada: nearly 20% of women and 10% of men harbor gallstones.  According to the Canadian Liver Foundation certain racial groups have an even higher incidence: in the aboriginal population between 70 and 80% are affected. Statistics in the US would be similar.
Leaders in gallstone research at Harvard Medical School came up with new studies recently from the large scale Health Professional Follow-up and the Nurses Health study with respect to how eating habits influence the formation of gallstones.

Dr. Chung-Jyi Tsai and colleagues examined the relationship between nut consumption and the risk of gallstone disease. Men who consumed about 5 oz of nuts per week had a significant decrease in gallstone development than those who ate less than 1 oz per month. Women fared similarly. The 20-year study involving 80,718 female nurses found that women who consumed at least 5 oz of nuts per week had a 25% lower risk of developing gallstones requiring gall bladder surgery than those who rarely ate nuts or nut butter. It turned out that not all nuts have equal benefits. Peanuts decreased the risk only by 19%, peanut butter consumption decreased the risk by 15%, whereas other nuts lowered the risk for gallstones by 35%. Nuts offer this prevention due to a combination of fiber, unsaturated fatty acids, as well as magnesium and beneficial plant chemicals. Fats as “the good guys” in gallstone prevention may sound like a novel idea, but there are differences in fats: it is the monounsaturated fats and the polyunsaturated fats that are the winners. They are the ones that are found in nuts or vegetables, but not in meat.

The coauthor of the Harvard study, Dr. Edward Giovanucci, points out, that a diet that is high in saturated fat (the fat which prevails in meat products) and high in refined carbohydrates (bakery products, pasta, sugar) increases the risk of gallstones. It also depends on the dosage: those who consumed a diet high in insoluble fiber decreased the risk by 17%. So, what is the reason? Insoluble fiber acts like a broom that sweeps waste out of the intestinal tract faster than a diet that lacks fiber. It also reduces the bile acid secretion, increases insulin sensitivity and lowers triglycerides (harmful blood fat levels). The good news is, that you can get it all at a local supermarket. Nuts, tomatoes, squash, cucumbers, whole grains like cracked wheat (as opposed to flour), beans, apples, berries and pears are all good and inexpensive sources.
