Ketogenic Diet With Ketone Supplementation

There is a newer way to shed some pounds using a ketogenic diet with ketone supplementation. Ketosis with a ketogenic diet is difficult to achieve because it requires a lot of fat consumption and at the same time extremely low carb intake to trigger the ketogenic response. The October 2019 issue of LifeExtension magazine contained an article about a ketogenic diet with ketone supplementation. There are dip sticks with which you can test your urine for ketone bodies to verify that your metabolism has switched to ketosis. But you can also take some ketone supplements including beta-hydroxybutyrate. By adding this supplement it is easier to achieve ketosis.

Why do people think of starting a ketogenic diet?

Calorie restriction can mimic the effects of fasting. It leads to ketone production and improved energy metabolism. Your blood sugar goes down, you lose weight and diabetes becomes easier to manage. In an animal experiment with worms with the pretty name “C. elegans” researchers fed beta-hydroxybutyrate to these roundworms. They extended their lifespan by 20%.

Many who are motivated to go on a ketogenic diet hope to lose weight and others may hope to live longer. One large US study from the Brigham and Women’s Hospital, Boston, MA showed that mortality over a period of 25 years was lowest when carbohydrates were in the 50 to 55% range. In the same study when carbohydrates were replaced in ketogenic diets with animal-derived protein and fat sources, mortality increased by 18%. Meat and fat were from sources such as lamb, beef, pork, and chicken.

Problems with ketogenic diets

Physicians have had the concern that their patients on ketogenic diets tend to eat cheap fats and meats that contain trans fats. These unhealthy fats lead to premature death from accelerated hardening of the arteries resulting in heart attacks and strokes.

The alternative: a ketogenic diet with ketone supplementation

A new approach to anti-aging is taking ketone bodies like beta-hydroxybutyrate as a supplement. A publication from 2017 stated that oral ketone bodies could mimic the life extending properties of caloric restriction. The authors stated: “An exogenous ketone ester provides a new tool for mimicking the effects of caloric restriction that can be used in future research. The ability to power mitochondria in aged individuals that have limited ability to oxidize glucose metabolites due to pyruvate dehydrogenase inhibition suggests new lines of research for preventative measures and treatments for aging and aging-related disorders.”

Another publication from 2017 describes how ketones can be used as alternatives to glucose for energy. Brain cells and muscle cells in particular are very capable to utilize ketone bodies for energy. Two principal ketones are significant: acetoacetate and beta-hydroxybutyrate. The liver is involved when fatty acids are broken down and ketones are manufactured.

Ketone metabolism

Ketones provide energy without raising blood sugar levels or stimulating insulin secretion. The body requires less processing of ketones to release energy. This means that less NAD+ is used to metabolize ketones. The end result is that more NAD+ circulates in the body, which is used to repair damaged DNA and helps slow down the aging process. Ketones mimic many of the effects of caloric restriction and intermittent fasting dieting. Ketone metabolism reduces risk factors for diabetes and heart disease.

Human experiments

A 2018 study took 20 individuals aged between 18 and 35 years and tested them with an oral glucose tolerance test. Half of the subjects received a ketogenic hydroxybutyrate monoester, the other half just water (placebo group). The ketogenic group had 16% lower blood glucose levels. Their insulin sensitivity was 11% lower. The authors concluded: “These results suggest that ketone monoester supplements could have therapeutic potential in the management and prevention of metabolic diseases.”

Longevity in humans 

There has been a lot of research in the last few years indicating that sirtuins (SIR1 and SIR3) are important anti-aging genes. NAD+ needs to activate sirtuins first to make them effective. Unfortunately with the aging process less NAD+ is available, which leaves the sirtuins genes inactivated.

In rat experiments feeding of a ketogenic diet resulted in increased levels of NAD+. The researchers measured an oxidative DNA damage marker in the hippocampus of the brain. This showed much less DNA damage in rats fed a ketogenic diet when compared to controls on a regular diet.

Study of humans with Alzheimer’s disease

Another human study examined the blood of Alzheimer patients, patients with mild cognitive impairment and normal controls.  Alzheimer patients had low ketone levels in the blood as well as low 2-hydroxybutyric acid. Overall this showed that there is a change in metabolism in Alzheimer’s patients that leads to low ketone bodies in the blood on one hand and beta amyloid deposits on the other hand leading to memory loss.

A further experiment with Alzheimer’s patients showed that cognitive function improved after elevation of ketone blood levels following ingestion of beta-hydroxybutyrate.

A healthy way to raise ketones

Investigators in this human study determined whether various ketone-drinks were elevating blood ketone bodies reliably. 15 volunteers received ketone esters or ketone salts as a drink. There was a reduction of blood pH by 0.1 units using ketone esters. The ketone salts elevated the urinary pH from 5.7 to 8.5. An experiment with 16 volunteers measured the effect of having a meal before taking ketone esters. The ketone blood level showed a reduction of 33% after the volunteers consumed a meal and they took the ketone supplement afterwards. Ketone supplements lowered blood glucose, lowered free fatty acid and also lowered triglyceride concentrations. On the other hand, there was no change of the electrolyte levels. The authors said: “We conclude that exogenous ketone drinks are a practical, efficacious way to achieve ketosis.”

Ketogenic Diet With Ketone Supplementation

Ketogenic Diet With Ketone Supplementation

Conclusion

The liver produces ketones when a person is fasting or is on a ketogenic diet. However the high fat content of a ketogenic diet can lead to atherosclerotic plaques in the arteries with the subsequent developments of strokes and heart attacks. A much safer way of raising ketone bodies in the blood is by taking ketogenic supplements by mouth. Animal experiments and clinical trials have shown that oral ingestion of ketogenic substances appear in the blood stream within 30 minutes and remain there for 3 to 4 hours. The body tolerates ketogenic supplements well with no side effects.

Prevention of Alzheimer’s disease, achieving weight loss and longevity

They likely will play a larger role in the prevention of Alzheimer’s disease in the future. Ketogenic supplements may be an adjunct to weight loss diets. In addition, fatty acids metabolize into ketones, which turn into energy in brain cells and muscles. Oral ketones stimulate the formation of NAD+, which activate longevity genes (sirtuins). Older people have a hard time to metabolize glucose because of certain enzyme deficiencies. But the brain and the muscle tissue can metabolize ketones rapidly, even in older age. Unfortunately the price of such supplementation is forbidding at the present time.

Omega-6 Fatty Acids Compromise Your Health

In an editorial of the October 2019 edition of LifeExtension William Faloon explained that omega-6 fatty acids compromise your health. He focused particularly on memory loss and the development of Alzheimer’s disease.

After a review of the medical literature he noted that Americans are eating too many foods that are laden with omega-6 fatty acids. Part of it is due to food processing with the wrong oils ). But the other problem is that processed foods also are full of omega-6 fatty acids. The merchants like omega-6 fatty acids, because they prolong the shelf life of products. But recent evidence shows that a high ratio of omega-6 to omega-3 ratio in our food can interfere with our memory and may even lead to dementia.

Evidence that omega-6 fatty acids are interfering with brain function

A recent publication analyzed 116 non-demented subjects aged 69 on average.

Blood tests were taken where 32 nutrients related to a Mediterranean diet were analyzed. In addition the researchers from the University of Illinois did functional MRI scans to assess higher brain function. The researchers also did cognitive tests to assess mental functioning.

  • The results of these experiments showed that higher lycopene levels had an association with better memory and higher executive function.
  • Subjects with higher carotenoids and trans lutein showed higher intelligence on testing.
  • B-vitamins that reduce homocysteine (vitamin B2, folate and vit. B12) and vitamin D showed an association with better executive functioning.
  • Two parts of memory testing showed that a proper balance of omega 6 to omega 3 ratio resulted in a better memory.
  • Higher omega-3 levels in the blood associated with higher overall intelligence and better executive function.

Impact of omega-6 on brain function

Researchers have proven that omega-3 fatty acids can help controlling inflammation in the body. This can prevent cardiovascular disease and neurodegenerative disorders like Alzheimer’s disease. However, our western food contains a surplus of omega-6 fatty acids, which causes inflammation in the body. It depends on our food choices, but it also depends on the preparation of the food. One chicken leg with skin contains about 1800 mg of omega-6 fatty acids. The process of deep-frying the same chicken leg increases the content to 4322mg of omega-6.

One deep fried KFC chicken breast with skin has 12,663 mg omega-6 fatty acids The reason is that a lot of the deep-frying oil is full of omega-6 fatty acids.

Cooking oils

Here is a run down of cooking oils. All of the cooking oils have a different mix of omega-3 and omega-6 fatty acid composition. Many also contain oleic acid, which is an omega-9 fatty acid.

Researchers have proven that omega-3 fatty acids can help control inflammation in the body. This can prevent cardiovascular disease and neurodegenerative disorders like Alzheimer’s disease.

As it is obvious from the table in the second last link olive oil contains 71.27% oleic acid, 9.76% omega-6 and 0.76% omega-3. It is the content of the majority of oleic acid (omega-9), which makes olive oil such healthy oil. Only two table spoons of olive oil per day will prevent heart attacks and strokes because oleic acid lowers the bad LDL cholesterol and increases the good HDL cholesterol. Olive oil removes beta-amyloid plaques inside the brain, which means it prevents Alzheimer’s disease.

Recommendation of best cooking oil

Considering that olive oil has such powerful healing properties, I recommend that you cook and bake with olive oil. Also use olive oil as part of your salad dressing. On the other hand avoid these oils: corn oil, sunflower oil, soybean oil, cottonseed oil and safflower oil. They contain too much inflammatory omega-6 fatty acids.

Our western food contains a surplus of omega-6 fatty acids, which causes inflammation in the body. It depends on our food choices what is in the food. But it also depends on the preparation of the food. One chicken leg contains about 1800 mg of omega-6 fatty acids. When it is deep fried with skin it contains 4322mg of omega-6.

One deep fried KFC chicken breast with skin: 12,663 mg Omega-6 fatty acids. One of the reasons is that a lot of the deep-frying oil is full of omega-6 fatty acids.

Math to calculate retained omega-6 from deep-frying

You notice that many cooking oils are high in omega-6. Soybean oil has 50.42% omega-6 in it. If you cook French fries or chicken in it and the food retains only 1 teaspoon of oil in it, that’s 5000 mg times 50.42%, which is 2521 mg of omega-6 added just from deep-frying your food.

Balancing omega-6 and omega-3 fatty acids

Omega-6 fatty acids are essential fatty acids that are mainly used for energy. But the problem is that in our western diet too many omega-6 fatty acids are in our food. Omega-6 fatty acids can be converted into arachidonic acid, which causes inflammation. This in turn can cause heart attacks and strokes on the one hand and arthritis on the other hand. In the past a healthy ratio between omega-6 and omega-3 was 4:1 or less. The average American now eats food with 16-times the amount of omega-6 fatty acids than omega-3’s. This is an omega-6 to omega-3 ratio of 16:1.

KFC chicken breast example

In the example of a KFC chicken breast with skin 12,663 mg omega-6 fatty acids are consumed. To balance this with omega-3 fatty acids the person would have to consume 3166 mg omega-3 fatty acids. One serving of wild salmon provides 2000 mg of omega-3. I take 3600 mg of molecularly distilled fish oil every day as a supplement (2 capsules in the morning and 2 at night). Together with the wild salmon this is 5600 mg of omega-3. This would result in an omega-6 to omega-3 ratio of 2.26:1, which is considered to be well balanced. But generally people do not consume so much seafood and fish oil supplements to balance the omega-6 fatty acids with omega-3. It comes down to be selective with your food choices.

Prevention of Alzheimer’s disease (dementia)

Since the mid 1980’s dementia cases have reduced by an average of 25%.

This is because people have become more conscious of healthier eating habits and supplements. More people take lycopene, a carotenoid supplement that helps prevent heart disease. Whatever helps the heart also helps the brain. Omega-3 supplements and consumption of seafood, especially wild salmon, is also useful. If people will reduce their omega-6 to omega-3 ratio to 4:1 or less, which too can help prevent Alzheimer’s disease.

Study to show that omega-3 fatty acids preserve the brain in older age

Here is a study that looked at brain structure using MRI scans. 3660 participants aged 65 received MRI brain scans. The researchers recorded their food intake with questionnaires. They rescanned 2313 of these individuals 5 years later. The group highest in omega-3 consumption was compared to the group with the lowest omega-3 consumption. Blood tests were also done both initially and 5 years later to verify the omega-3 intake. The researchers found that the higher omega-3 group had less subclinical infarcts and the white matter of the brain was of a better grade. They concluded that fish consumption, the major source of omega-3 fatty acids, had a beneficial effect on brain health later in life.

Omega-6 Fatty Acids Compromise Your Health

Omega-6 Fatty Acids Compromise Your Health

Conclusion

Omega-6 fatty acids are abundantly present in junk food, deep fries, processed foods and polyunsaturated oils like corn oil, sunflower oil, soybean oil, cottonseed oil and safflower oil. Because food processors like the long shelf life of processed food made with these oils, people’s intake of omega-6 fatty acids has been climbing. Now the omega-6 to omega-3 ratio regarding the average American food consumption is about 16:1. It should be 4:1 or less. It is important that you learn what contains omega-6 fatty acids and that you start cutting down. You do need a certain amount of omega-6 fatty acids for cell energy, but most people do not get enough marine based omega-3 fatty acids. Wild salmon and other seafood provides omega-3 fatty acids.

Balancing omega-6 with omega-3

I have shown using an example how you can balance omega-6 and omega-3. Having the right ratio of omega-6 to omega-3 will also help you prevent dementia down the road. Consuming more olive oil can prevent heart disease and dementia as well. This contains oleic acid (an omega-9 fatty acid), which lowers LDL cholesterol and raises HDL cholesterol.

What Makes Us Sick And What Keeps Us Healthy

An article in Nature Communication essentially asks what makes us sick and what keeps us healthy? The publication is about eating enough flavonoids to protect you from heart attacks and cancer.

The publication appeared on Aug. 13, 2019. It is a prospective study involving 56,048 participants of the Danish Diet, Cancer, and Health cohort. The medium age of the participant in the beginning of the study was 56 (range 52 to 60). This was cross-linked with Danish nationwide registries. The observation time was 23 years during which 14,083 participants died. As this study had a high number of participants and had a long observation period, the data are quite robust.

The researchers found that when people consume 500 mg of flavonoids from vegetables and fruit per day, they are dying significantly less from heart attacks and cancers.

Details of the study on flavonoid intake

Flavonoids are polyphenolic compounds in plant-derived foods and beverages such as vegetables, fruit, dark chocolate, coffee, tea, and red wine. There are six major subcategories of flavonoids: flavonols, flavan-3-ols, flavanones, flavones, isoflavones and anthocyanins. But it does not matter, which ones we consume, just that we consume enough (more than 500 mg per day).

The results were obtained with much stratification. For instance, in one set of results they normalized for age and sex. They called this model1. In another set they adjusted for age, sex, BMI, smoking status, physical activity, alcohol intake, hypertension, hypercholesterolemia, social economic status (income), diabetes, and prevalent disease. They called this model 2.

Participants with 536 mg of daily flavonoid intake had a reduction of 39% of heart attacks according to model 1. Using model 2 this changed to a reduction of 18% of heart attacks.

Cancer mortality reduction

The investigators did a similar analysis for cancer mortality reductions. At 536 mg of daily flavonoid intake model 1 showed a 36% reduction of cancer mortality. Model 2 still calculated a 21% reduction of cancer mortality. In both cases, the cardiovascular mortality risk and the cancer risk showed that more than 500 mg of flavonoids per day were not necessary as no more lives were saved by increasing the flavonoid dose beyond that. Unfortunately the opposite is true: people eat too many processed foods devoid of flavonoids, and they die of heart attacks and cancer prematurely.

Reducing the risk of heart attacks and cancer is not new

Many studies have shown what researchers found in this study, namely that vegetables and fruit can prevent heart attacks and cancer. Here is a brief summary with links to show this.

We heard many times that small amounts of alcohol consumption will keep the arteries clear of fatty deposits. This prevents heart attacks and strokes, but as the following study shows even small amounts of alcohol can cause various cancers.

Small doses of alcohol are still cancer producing

Dr. Timothy S. Naimi from Boston University Medical Center was the main investigator of an international team of scientists. The study found that every year 18,200 to 21,300 cancer deaths in the US (that is 3.2% to 3.7% of all US cancer deaths) are due to alcohol consumption. The authors of the study determined that every person who dies from alcohol related causes lost on average approximately 18 years of his/her life (scientists call this “years of potential life lost”).  51% of women developed breast cancer from alcohol exposure, 62% of men came down with upper airway and esophageal cancers. Less than 1.5 drinks per day caused between 26% and 35% of alcohol-related cancer deaths. There was no safe lower margin. The authors concluded, “Reducing alcohol consumption is an important and underemphasized cancer prevention strategy”.

Lifestyle important for longer life expectancy

I am reminded of a talk that Dr. David Katz delivered in a keynote address. He said that lifestyle improvements create profound changes in our system. This talk took place at the 22nd Annual World Congress on Anti-Aging Medicine in Las Vegas Dec. 10-14, 2014. One study that was mentioned showed that in men who adopted a healthy lifestyle 35% of heart attacks could be prevented. With healthy lifestyle the authors meant consuming a healthy diet, not exceeding moderate alcohol consumption, no smoking, regular physical activity and having a normal waist circumference (less than 95 cm).

The ingredients you need to make it to age 100

A Swedish longevity study that went on for 50 years gave me the idea to write a blog about the factors that can help you to turn 100 and still have your mental capacity and good health.Let me introduce you to this study. Researchers at the Sahlgrenska Academy in Göteborg, Sweden (which is located at the University of Gothenburg) decided back in 1963 to follow a group of 855 Gothenburg men born in 1913 until they would either die or turn 100. The idea was to find out what killer diseases are in the way to reach such a ripe old age and if they would survive, what was it that made them reach this age. Think of it as a race to turn 100.

What diseases killed at older age and what led to longevity?

The researchers had checkpoints along that journey: various surveys were conducted at the age of 54, 60, 65, 75, 80 and 100 to analyze the factors that lead to longevity. 27% (232) of the original group reached the age of 80, and 13% (111) made it to 90. Only 1.1% of the men made it to the age of 100. What were the causes of death for the other ones who did not make it? 42% of deaths after the age of 80 were due to heart attacks, 20% due to infectious diseases, 8% due to strokes, 8% due to cancer, 6% due to pneumonia and 16% due to other causes. 23% of the men over 80 were diagnosed with Alzheimer’s or dementia. Factors that made people survive were refraining from smoking, maintaining a healthy cholesterol level and limiting coffee consumption to not more than 4 cups per day.

Beneficial effects of green tea and black tea

meta-analysis 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.

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 (heart attacks and strokes) by 33%. The highest black tea consumption lowered mortality by 12%. Cancer mortality turned out different. Green tea did not produce a reduction in mortality, but black tea lowered it by 21%. I suspect that the different subcomponents of the bioflavonoid content in green and black tea are key to those findings.

Plant-based diet versus animal protein based diet

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. The investigators substituted 3% of energy from processed red meat by an equivalent amount of plant protein. This reduced the all-cause mortality by 34%. For unprocessed red meat the 3% substitution reduced the all-cause mortality by 12%. If 3% of egg consumption is reduced, all cause mortality drops by 19%.

British Medical Journal study

new study has shown that you can save lives when you replace red meat and processed red meat. The replacement was with fish, poultry or protein from vegetables. The study appeared in the British Medical Journal on June 12, 2019. It involved 53,553 women nurses and 27,916 male doctors in the United States and ran from 1986 to 2010. Here is my summary of the blog where I reviewed this study in detail. A new study in the British Medical Journal showed that an increase in red meat consumption of only ½ serving per day for 8 years caused an increased mortality of 9% over the following 8 years. With regard to processed red meat the mortality was even bigger, namely 13%. The researchers replaced some of the meat with white chicken meat or vegetables and the mortality normalized.

In contrast, a Japanese study showed that there was no increase in cardiovascular disease with the consumption of up to 100 grams of beef or other meat products per week. The study went on for 16 years.

Using antibiotics as growth promoters is illegal in Japan and Europe

I pointed out before that there is literature explaining why there is a discrepancy: the beef industry in the US feeds the animals antibiotics as growth promoters. This changes the bowel flora in humans who eat the beef. The changed bacterial strains in the gut use carnitine from beef and make trimethylamine N-oxide (TMAO). This is a toxin that causes both cardiovascular disease and cancer. This explains why in the US beef is one of the culprits that cause heart attacks and colorectal cancer. In Japan this is not the case. Both Japan and Europe do not use antibiotics as growth promoters in the cattle industry, as it is illegal.

In the US it is likely safe to eat organic meats (beef, chicken) as these meats will not contain antibiotics. Due to the numerous additives in processed red meat, it is a sensible idea to skip these products altogether, as they produce cancer.

What Makes Us Sick And What Keeps Us Healthy

What Makes Us Sick And What Keeps Us Healthy

Conclusion

Several studies have pointed out the importance of eating less animal protein and increasing vegetables and fruit in your diet. Heart attacks, strokes and cancers are still the major causes of death in all of the developed countries. The Danish study mentioned in the beginning showed that keeping the daily intake of bioflavonoids at 500 mg or more prevented 18% to 39% of heart attack mortality and 21% to 36% of cancer mortality.

In other studies we learnt that deaths between the ages of 80 and 100 were mainly due to heart attacks, strokes and cancer (these accounted for 58% of deaths). Only 1.1% of the men in that Swedish study made it to the age of 100.

More evidence that flavonoids and plant protein save lives

Another study measured the effect of green and black tea consumption: There was a 21% reduction of strokes with green or black tea consumption.

Another study found reduced cardiovascular mortality by 33%. Green tea reduced cancer mortality by 21%.

Another study showed that when plant protein replaced red meat there was an astounding drop of the all-cause mortality by 34%.

All of these studies show that you must eat enough flavonoids to protect yourself from heart attacks and cancer. Of course you also need to engage in a regular physical exercise program to stay fit and healthy.

How Healthy Is Food From The Supermarket?

I am asking the question here: “how healthy is food from the supermarket?” We tend to assume that food we buy at the supermarket would be safe to eat. Think again, because below I will explain why it is NOT safe.

The “dirty dozen”

You may or may not have heard about the “dirty dozen”. The Environmental Working Group (EWG) is a non-profit organization that monitors fruit and vegetables for insecticide residues. For 2019 they have determined these unhealthy dozen of fruit and vegetables: strawberries, spinach, kale, nectarines, apples, grapes, peaches, cherries, pears, tomatoes, celery, potatoes and peppers (hot and bell peppers). Yes, you counted right, this “dozen” actually consists of 13 items.

When I want to buy any of these fruit, I strictly get fruit and vegetables, which are organic. If this is not available in the regular supermarket, I go to the health food store and buy organic fruit and vegetables there. Local farmers’ markets also offer organically grown produce. Every year the EWG brings out an up-to-date list of the dirty dozen. If an item is not on this list, you can assume that it is safe to eat.

Sugar and too many starches are the next problem

How healthy is food from the supermarket? We said we wanted healthy food. Unfortunately ample consumption of sugar and starchy foods end up as belly fat and also as atheromatous deposits in the arteries. I do not eat bread unless it is 100% rye, but then only 1 or 2 slices occasionally. I do not eat potatoes, rice or pasta. Those who love pasta can eat the pasta-look-alike, called shirataki, which is made from the glucomannan root (also known as konjac root). The carbs here are bound to fiber, which digest a lot slower than regular pasta. So, this means that you are bypassing the section in the supermarket where they sell muffins, donuts etc.

Processed foods

In the center of the supermarket you find all kinds of processed foods. They are usually full of sugar, salt and unhealthy fats (hydrogenated fats). People who eat a lot of processed foods are more prone to get heart attacks, strokes and may even come down with cancer. It is not the kind of food that I want. Instead I like whole foods like organic apples, berries and raw or cooked vegetables.

Fish section

I like salmon, sole, cod, halibut, trout, mussels, shrimp and squid. But I am careful not to load up on the big predator fish like tuna. One has to be careful about methylmercury content in fish. I reviewed fish, mercury contamination and the benefits in this link.

As this link shows, there are low, medium and high methylmercury contaminated fish. The higher the fish is in the predator chain, the higher the methylmercury content. This is of particular concern for pregnant women as mercury is toxic for the fetal brain tissue. But they can consume low mercury fish and shellfish, like mackerel, herring, wild salmon, shrimps or clams. I figure, what’s good for women who are pregnant is good for other people. As a result, I limit my fish meals to the low methylmercury contaminated fish category.

How healthy is food from the supermarket – Meat section

Now your shopping trip becomes problematical. There has been news from the Word Health Organization at the end of 2015 that red meat and red meat products are class 1 carcinogens.

This would mean that you may come down with colorectal cancer, if you consume red meat and red meat products regularly. This is when I stopped eating red meat and red meat products like prosciutto. Unfortunately this warning includes pork, lamb and all sausages as well. In the meantime further research has shown that antibiotics that are fed to beef before they are slaughtered get into the meat and change the human bowel flora when red meat or red meat products are consumed.

Trimethylamine N-oxide (TMAO)

There is a change in bowel flora that causes chemical reactions in the gut with the consumption of beef and eggs. Beef contains carnitine, which can lead to the production of TMAO (trimethylamine N-oxide).

Egg yolk contains choline, which also raises TMAO levels in the blood.

In the following study 113 healthy men and women consumed either a meat diet (beef), white meat diet or protein from non-meat sources. After one month the beef group had triple the amount of TMAO in their blood compared to the other two diets.

Interestingly, when the diets were switched the TMAO levels normalized again in the former beefeaters, when consuming white meat or protein from non-meat sources.

What meat am I shopping for?

I recommend not to eat beef more often than once per week and to eat only grass-fed beef. I eat organic chicken and ground turkey breast meat from health food stores (the turkeys are NOT fed antibiotics). Otherwise I eat seafood, cheese from non-recombinant growth hormone milk. This means that I only buy European import cheese or Canadian cheese. In the US you have to ask for organic milk and organic milk products.

The deep frozen section

I look for deep frozen vegetables, fruit, and fish as well as meats. As vegetables are quickly readied for the freezer, their vitamin content can be higher than that of a vegetable that has spent 8 days in transit from the field to the produce department. The deep frozen section also gives you access to a lot of variety. You’ll be able to enjoy some organic strawberries, even when they are not in season. Read the labels, as some fruit have been packaged with sugar syrup. Look for the varieties, where no sugar has been added. The frozen section also contains some highly processed items: deep-fried foods and dessert selections, which have nothing to do with health, so I avoid them.

Canned foods

Canned foods can be useful, as long as you are dealing with fruit that are canned in their juices and not in sugar syrup. The vegetables are less valuable in vitamins than their deep frozen counterparts. Watch out for varieties, where less salt is added. The label will tell you ”low sodium”. Also pay attention to the cans. Those that are not lined with BPH have a label that emphasizes this. You can avoid this by buying canned food in glass jars, such as tomato sauce.

Cosmetics

You will not have to navigate all the aisles, except for your cleaning products and your cosmetics. These have their own problems: lots of cosmetics contain Parabens. Leave them on the shelf, and be aware that some cleaning products can be hazardous too. Pick environmentally friendly, non-toxic products!

Staples you need

There are some staples, which you will also require: olive oil, some olives, almonds or macadamia nuts (preferably raw). The one cereal product, which is valuable will be coarse rolled oats and some pot barley. Both varieties carry a lot of fibre, which makes them very useful food staples. Avoid the “quick cooking” or “instant” oats. Due to the processing, the carbohydrates are absorbed a lot faster and consequently trigger a higher insulin response.

Drinks

You will wonder about drinks next. Having passed the colas, ginger ales and other sugar pops you may eye the diet drinks. Beware of drinks sweetened with aspartame. There is increasing evidence that phenylalanine (brand names: Aspartame, NutraSweet and Sweet’N Low) is not a “harmless” sweetener. Newer research has shown that it can cause gastroesophageal reflux (=GERD) and migraine headaches. Stevia, a sweetener from a South American plant, does not have harmful effects. Stevia is safe to use, as it does not cause an insulin response. You are best served with mineral water, purified drinking water, herb teas, tea or coffee. Fruit juices do have vitamins and minerals, but they are high in sugar causing an insulin release.

What is in fruit juices?

You would not really eat 3 large apples in one sitting? Probably not! So why insist on drinking 8 oz. of apple juice? You’ll ingest all the sugar and forgo the fibre! You also notice that a lot of fruit juices have been mixed with sugar, water, artificial flavor, some color, and as an apology some vitamin C has been added. They are appearing on the shelves as “a good source of vitamin C”. In reality we are dealing with flavoured, colorful sugar water. Use your own judgement, whether you want to spend your dollars on this selection!

Power bars, snacks

In the aisle adjacent to the pop you will very likely encounter a huge selection of convenience and snack foods. They have several things in common: you have met them on TV, some will be high in starches and fat (chips), others will be high in starches, sugar, and fat (cookies, donuts, cream pastries), and we are dealing with trans fats. Do take time to read the listed ingredients, and then decide, whether you and those who eat in your household deserve nutritional garbage. 

How Healthy Is Food From The Supermarket?

How Healthy Is Food From The Supermarket?

Conclusion

We have now completed our round trip in the supermarket. You may still be in mild shock, noticing that “healthy” foods are not the general rule on the shelves. When we buy vegetables and fruit we have to be aware of the “dirty dozen”, which is contaminated with insecticides. We will not buy anything on that list, but buy instead the organic version. You may have to go to the health food store to get these items. Red meat and red meat products produce carcinogens in the human gut. It seems to stem from antibiotics that are used in beef farms and chicken farms. With chicken I buy organic chicken. With beef you need to be more careful and reduce the consumption to once per week and eat only grass-fed beef.

It is tricky to buy healthy food from the supermarket

Much of the bakery section is useless. It consists of empty starch that is digested into sugar and leads to an insulin response. I avoid the processed food section, which contains unhealthy ingredients. Fish is great as long as it does not have too much methylmercury in it. Deep frozen foods may be useful.

Shopping for healthy foods from the supermarket has become more complicated than it was in the past. I only select healthy items and supplement the rest from the health food store. This way I get what I need and avoid the pitfalls of merchandise, which is not beneficial.

Fasting Mimicking Diet For 5 Days Every Month

In December 2017 I heard Dr. Longo speak at a medical conference in Las Vegas. He suggested the use of the fasting mimicking diet for 5 days every month. I am getting into the age group where a little help from nature would not harm (I am 74 years old). I started immediately in December 2017 to do a fasting mimicking diet (FMD) for 5 days.

Effects of fasting mimicking diet

In the beginning you just notice that you are not as hungry as you thought you would be, because you do take in three mini meals of about 200 calories each, which curbs your appetite. It is also important to consume enough liquids. Please note: liquids! Not liquor! Wine, beer or any alcoholic drinks are not part of the diet. You can drink water, but, this may get boring, and you can take water with lemon, herbal teas, black tea and coffee, as long as you stay away from sugar-laced drinks.

How the FMD works

Your total calorie intake will amount to no more than 600 calories per day for the 5 days where you do the fasting mimicking diet. Your body mass index (BMI) decreases between 0.1 and 0.4 per day to a total of 0.5 to 0.9 for the 5 days. This does not seem much, but if it is accumulating every month, a person who is obese now could have a normal weight within one year. The first day of this fast may present some challenges. I found that in the afternoon I felt hungry. What helped was a hot drink( tea, coffee, clear broth). Day two was better, and from day three it has become a routine. There are  no ferocious hunger pangs, no headaches or feelings of weakness or tiredness. I am always surprised that my energy level is improving when I do the fasting mimicking diet for 5 days every month.Dr. Longo suggests not to exercise during the fast. It is obvious that this time is not suitable for half- marathons or taxing hikes, but I found that thirty minutes of aerobics and thirty minutes of weight training felt good. Listen to your body! If you feel lightheaded at any time, stop! The emphasis is on “moderate”.

Dr. Longo noticed the following findings in a mouse model as well as on humans. I summarized this before in a previous blog:

Specific results when on the fasting mimicking diet for 5 days every month

  • Obesity diminishes, because of the weight loss effect due to missing calories.
  • 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
  • Pain conditions improve as all kinds of pain disappears, an effect for which there is no explanation at this point
  • Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
  • Prevention of heart attacks and strokes because of reduction of LDL, triglycerides and CRP
  • Cancer cure rates improve by protecting normal cells, the bone marrow and stimulating the immune cells
  • 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 leads to less disease in older age.

Meal samples of fasting mimicking diet

Dr. Longo developed a kit containing all pre-packaged foods for 5 days under the name “ProLon Fasting Mimicking Diet”. The package is not larger than a shoebox, and the diet is plant-based, has some nutrition bars, drinks as well as freeze-dried soups. You can argue about the nutritional value, as it has an average rating of 3.5 out of 5. It also comes in at a hefty price of 300.00 USD. In reality it is a matter of calorie-math to consume very little food. There are plenty of tables available on the Internet that tell you the nutritional value of foods, and it does not take much effort to compose your own menu.

Here is a fairly typical list of foods

Breakfast: A typical breakfast consists of 2 slices of rye crisp bread (Wasa or Ryvita) with a bit of almond butter on it, a cup of coffee and either black or with stevia and milk.

Lunch: 8 oz. of tomato soup and coffee or tea.

Dinner: A tossed salad with organic bell peppers, ½ tomato, and two thin slices of avocado, vinegar and 1 tablespoon of olive oil.

Here is an alternative meal sample:

Breakfast: Eat a nutrition bar that is based on nuts. It should not be more than 250 calories. Alternatively make your own! Have tea or coffee.

Lunch: 8 oz. of homemade vegetable soup without the addition of pasta or beans.

Dinner: Miso soup and 4 rice crackers, alternatively a small tossed salad with olive oil and vinegar.

Results of fasting mimicking diet for 5 days every month

Here are typical results that I found over several months. I am using body composition scales every day to measure my weight, body fat percentage, visceral fat percentage, muscle percentage, calories burnt and the BMI.

One month the BMI went from 21.9 to 21.1 during a 5-day FMD. Another month the BMI experienced a reduction from 21.7 to 21. 2. Here is a list of the some of the 5-day losses of my BMI on a couple of occasions: 0.8, 0.4, 0.9, 0.7, 0.6, 0.5, 0.7 and so on.

It is important that you are not going on an eating binge after those five days. The FMD conditioned your body to be content with very small amounts of food. Enjoy your food, but stick to moderate portions.

Discussion of fasting mimicking diet for 5 days every month

An intermittent fasting mimicking diet was shown to have a diversified positive health effect in both animal models and humans. For instance, inflammatory bowel disease improves on FMD by improving the bowel microbiota and by promoting the intestinal regeneration.

Intermittent fasting, as this article shows, can prevent age-associated diseases.

This article suggests that T-killer cells that attack cancers are promoted by the intermittent fasting mimicking diet.

A FMD in type 1 diabetic patients has been shown to restore insulin generation in islets of the pancreas of these patients. The result was an improvement of their type 1 diabetes.

More research data on fasting mimicking diet

A clinical trial with 100 subjects was undertaken by Dr. Longo and his research team. He measured markers after 3 cycles of a fasting mimicking diet for 5 days every month. They found that the FMD reduced aging markers, improved diabetes and reduced susceptibility for cancer and cardiovascular disease. In another publication Dr. Longo and co-authors describe how autoimmune diseases can be improved by the use the fasting mimicking diet for 5 days every month.

Another publication by Dr. Longo describes that “age-related disorders including diabetes, cardiovascular disease, cancers and neurological disorders such as Alzheimer’s disease, Parkinson’s disease and stroke” can be prevented by fasting mimicking diet for 5 days every month.

Even cancer prevention and cancer treatment can be helped by the fasting mimicking diet.  The FMD makes chemotherapy more tolerable.

Fasting Mimicking Diet For 5 Days Every Month

Fasting Mimicking Diet For 5 Days Every Month

Conclusion

I have shown that with the fasting mimicking diet (FMD) done for 5 days in every month you can lower your body mass index (BMI) by 0.4 to 0.9 units. On the long-term this helps you to keep your BMI stable and in the 21.0 to 22.0 range. Dr. Longo has researched the effect of the FMD in both mice and humans. He found that you age better with less age-related diseases. In addition, inflammatory bowel disease, autoimmune diseases like MS, rheumatoid arthritis and type-1 diabetes improve. Cancer patients who need chemotherapy tolerate it better. Their immune system also produces more killer T cells that destroy cancer cells. The FMD prevents heart attacks, strokes and cancer. Dr. Longo also has shown that there is stimulation of stem cell production and telomeres are increasing in length. Telomeres are important for longevity, which allows you to age healthier with less disease.

The Best Ways To Prevent Cancer

Cancer is the second leading cause of death, that’s why it is important to learn about the best ways to prevent cancer. Generally speaking you want to remove cancer-producing substances (carcinogens) from your diet. But diet is only part of your lifestyle that can contribute to cancer. I shall list some of the more important dietary factors below and briefly touch on important other factors.

Avoid burning your meat

When you use the BBQ, you should avoid burning your meat. Even though the marks of “charring” are considered desirable on meat from the grill, this is really burnt! As a matter of fact it is a lot better to use a slow cooker at low heat and simply cook your food longer. This way you don’t create carcinogens. Avoiding to burn your meat is particularly important for the red meats.

Sugar and an overabundance of starchy foods can cause cancer

You never thought that sugar and an overabundance of starchy foods could cause cancer, but they do. The reason is that the metabolism of cancer cells is using 10- to 12-times more sugar than the metabolism of normal cells. The worst thing a cancer patient can do is to over-consume sugar. Replace sugar by stevia, which is a harmless, plant-based sweetener and does not lead to an insulin reaction. Avoid all other sugar substitutes, as there are other heath problems with most of them.

Avoid phthalates

Those who have a craving for macaroni and cheese are out of luck. This food contains phthalates that are part of the ingredients of almost every sample of cheese powder used to manufacture macaroni and cheese. Phthalates can cause infertility and breast cancer. So you must definitely avoid macaroni and cheese, at least the stuff from the box. Prepare your own!

A high fat diet

What does a high fat diet do? It increases the risk for breast cancer. But it can also increase colorectal cancer risk. Limit your fat intake to about 10% of saturated fat. That is the recommendation of the FDA. Increase your consumption of fish and seafood. Only one proviso: predator fish like shark, marlin, tilefish, swordfish and grouper are high in mercury. But wild salmon, sardines and oysters are low in mercury. You can also enjoy shrimps and prawns.

Take high dose vitamin D3 supplements

High dose vitamin D3 supplements help you to avoid cancer. There are strong statistics showing that vitamin D3 is a powerful tool to lower your risk of developing cancer. Your family doctor should take a blood test called 25-hydroxy vitamin D level to make sure that you absorb enough vitamin D3. There are slow and fast absorbers and the only thing to know how well your gut absorbs vitamin D3 is in doing this blood test.

Also, curcumin (turmeric) 500 mg once per day is good for cancer prevention.

Take enough fiber

Make sure you take enough fiber, which does not only reduce colorectal cancer, but also many other cancers. When you eat plant-based food, you automatically get fiber in it. North Americans are not consuming enough fiber in their diet.

Avoid processed meat and too much red meat consumption

Processed meat and red meat cause cancer.

Beef, lamb and pork seem to contribute to causing cancer according to the WHO. Use common sense and eat fish, chicken and turkey. Reduce your beef consumption. My grandmother served beef as a Sunday dish.The rest of the week simple, plant-based foods appeared on the table. Ask your grandmother, what she used to cook. Or ask your mother what she ate as a child.

Eat moderate amounts of fruit and vegetables

The claim that fruit and vegetables would protect you from cancer is not as solid as researchers thought of in the past. Newer research has shown that a basic intake of fruit and vegetables is needed for nutrients, but consuming more than that will NOT protect you from cancer.

This link explains that eating more vegetables or fruit beyond a certain point will not do harm, but will not protect you further from cancer.

Drink green tea or black tea

If you like tea, drink green tea or black tea. Sweeten it with stevia, but not with sugar. Tea has been shown to have cancer prevention properties.

Avoid alcohol consumption to prevent cancer.

Coffee is a healthy drink and it has mild anti-cancer effects as well. It does not matter whether you drink it caffeinated or decaffeinated.

Other lifestyle issues

Quit smoking

If you are still smoking, quit smoking! Smoking is by and large the biggest risk for developing lung cancer, throat cancer, esophageal cancer and pancreatic cancer.

Watch your calorie intake

Eat smaller meals more often. This way the production of your digestive juices will consume some calories. In addition your taste buds are satisfied, so your hunger for food is more controlled. The end result is that you will not gain weight.

Prevent obesity and type 2 diabetes

This will help prevent obesity and type 2 diabetes, both of which are established risk factors to develop cancer. Here is a review that shows you, which cancer types are caused by obesity. With regard to diabetes, there is a strong association to developing liver cancer, pancreatic cancer and endometrial cancer (=uterine cancer). There is a lesser risk (only 1.2 to 1.5-fold) to develop cancer of the colon and rectum, breast cancer and bladder cancer.

Pollution

Poor air quality with pollution can also be a factor in causing cancer. Pollution does not stay local, but travels through the stratosphere around the globe. The result is that now 10 to 15% of lung cancer in the US occurs in patients who never smoked. This translates into 16,000 to 24,000 deaths annually of never-smokers in the US. In certain cities such as Beijing lung cancer rates have doubled in 9 years between 2002 and 2011. Lung cancer in non-smokers can be caused from exposure to radon, to second-hand tobacco smoke, and other indoor air pollutants.

Bioidentical hormone replacement

When males do not replace missing testosterone in andropause they are much more prone to develop prostate cancer. Similarly, when women are menopausal and do not get progesterone supplementation, they develop a higher amount of breast cancer due to estrogen dominance. It follows from this that bioidentical hormone replacement in menopause and andropause will help to prevent prostate cancer and breast cancer.

The Best Ways To Prevent Cancer

The Best Ways To Prevent Cancer

Conclusion

There is strong evidence that certain foods can cause cancer. Other foods including supplements like curcumin and vitamin D3 can help prevent cancer. Basically, you want to avoid all that is known to cause cancer and eat more of the healthy foods that do not cause cancer. This will help to decline your cancer risk. I suggest that in addition you should quit smoking, avoid pollution as much as possible, reduce excessive alcohol intake and watch your calorie intake. By doing this you prevent obesity and type 2 diabetes, and you will move into the low-risk cancer group. We all need to work on this on an ongoing basis.

Practical hints regarding the best ways to prevent cancer

The best ways to prevent cancer is to avoid processed red meat and all other processed foods. Eat more vegetables, fruit, wild salmon and other seafood. Don’t eat red meat more often than once a week and make it red meat from grass fed animals. In addition exercise regularly, get enough sleep and practice some form of relaxation (yoga, Tai Chi, self-hypnosis etc.). This lifestyle will not only prevent heart attacks and strokes, but also the majority of cancers.

Replace Red Meat And Processed Red Meat

new study has shown that you can save lives when you replace red meat and processed red meat. The replacement was with fish, poultry or protein from vegetables. The study appeared in the British Medical Journal on June 12, 2019. It involved 53,553 women nurses and 27,916 male doctors in the United States and ran from 1986 to 2010. Every 4 years comprehensive diet sheets were compiled on each of the participants. Death rates of all of the clinical trial participants were also recorded. The amount of red meat or processed red meat servings, which the participants consumed per day was recorded. One serving of red meat is 3.5 ounces or 100 grams.

Results of the BMJ study

People consuming ½ a serving (50 grams) of red meat more per day over 8 years, had an increased mortality. It was increased by 9% over the following 8 years. Similarly, people consuming ½ a serving (50 grams) of processed red meat over 8 years, were in trouble. They had an increased mortality of 13% over the next 8 years. The researchers also found that when people ate less red meat and processed red meat, things normalized. Their mortality returned to a normal rate. Also, when people replaced red meat with fish, poultry and vegetables, the mortality figures went down as well.

Red meat consumption in the literature

The researchers reviewed the literature regarding disease risk and mortality with meat consumption. In particular, the researcher had an interest in increased red meat consumption and consumption of processed red meat. Other investigators mentioned that there was an increased risk of type 2 diabetes, colorectal cancer and other cancers.  In addition, cardiovascular disease and increased overall mortality were up with meat consumption. The worst variety of processed foods are bacon, hot dogs, and sausages. Certain lung diseases like chronic obstructive pulmonary disease and heart heart failure are directly related to consumption of red meat or processed red meat products. Hypertension also has a link to red meat consumption. Components of red processed meats such as saturated fats, polycyclic aromatic hydrocarbons, preservatives and sodium can cause colorectal cancer and at the same time cause cardiovascular disease.

More details about the study

There were 8426 deaths among the nurses branch of the study. 3138 nurses died from cancer, 1774 from cardiovascular disease, 939 from neurodegenerative diseases, 751 from respiratory diseases, and 1824 from other causes. In the same time period (24 years) there were 5593 deaths among the males of the Health Professionals follow-up study. 1754 died from cardiovascular disease, 1754 from cancer. There were 434 deaths from respiratory diseases, 375 from neurodegenerative diseases, and 1276 from other causes.

Red meat consumption in women has decreased by 31% in the past 24 years. Men have cut back their red meat consumption by 11% in the same time period.

One subgroup of patients decreased their red meat consumption and replaced it with a higher intake of nuts, poultry (without skin), fish, dairy, eggs, whole grains and vegetables over 8 years. They had a lower death rate than the controls over the next 10 years.

Discussion of the BMJ study

The authors mentioned that a Japanese study found no increased mortality among 51,683 Japanese men and women eating red meat, poultry, processed meat and liver. There were 20,466 men and 31,217 women, aged 40-79 years. The study lasted for almost 16 years. There were 2685 deaths due 537 ischemic heart diseases and 1209 strokes. The investigators had traced how much meat the participants ate. They did not find any change in mortality up to 100 grams per day of beef or other meat consumption. I will discuss this further below.

Hormones and antibiotics may be partially responsible for higher mortality in the US

Dr. Valter Longo, professor of biological sciences at the University of Southern California and director of the USC Longevity Institute was not part of the study. He commented: “The lower or lack of association between red meat intake and mortality in other countries or areas of the world indicates that red meat may contribute to mortality in the United States by providing a high protein content but also because it may contain other factors that contribute to damage.“ He also questioned certain agricultural practices where hormones and antibiotics are in use in the raising of beef cattle in the US. This is not the case in Japan or Europe. He went on to say: “The reduced mortality, when red meat is replaced with fish, is consistent with this possibility since they contain generally similar levels of proteins”.

Use of antibiotics in cattle farming

The accepted practice of using antibiotics not only for treating infections, but also for accelerating growth in beef cattle has far-reaching ramifications.  The problem is that use of antibiotics in milk cows produces milk with antibiotic residues. In beef cattle antibiotic residue are also in the meat of these cows.

The question arose whether or not the use of antibiotics in cattle would possibly cause resistance to antibiotics in humans. This publication examines this question. It comes to the conclusion that the probability of resistant strains of bacteria in humans as a result of the feeding of antibiotics to cows in the US would be small. However, there is another aspect that only recently has gained attention. It is the change of the gut biome in humans as a result of antibiotic residues from the standard agricultural practices of raising cattle.

Change of the human gut biome

Meat eaters have raised TMAO blood levels

The human gut flora can change for various reasons. But once it has changed, it often stays in an altered state. It is a permanent change in bowel flora that can cause chemical reactions in the gut with the consumption of beef and eggs. Beef contains carnitine, which can lead to the production of TMAO (trimethylamine N-oxide). Egg yolk contains choline, which also raises TMAO levels in the blood.

In the following study 113 healthy men and women consumed either a meat diet (beef), white meat diet or protein from non-meat sources. After one month the beef group had triple the amount of TMAO in their blood compared to the other two diets. Interestingly, when the diets were switched the TMAO levels normalized again in the former beefeaters when consuming white meat or protein from non-meat sources.

Changed gut flora causes raised TMAO levels

The use of antibiotics as growth promoters in the US beef industry is the standard practice for raising beef. But this has led to antibiotic residues that are detectable in the laboratory. When a person eats beef that is contaminated with antibiotic residues, the bowel flora loses its diversity of bacteria in the gut. This leads to an accumulation of other bacteria that produce TMAO in the presence of beef or egg yolk and can cause cardiovascular disease on the one hand and cancer on the other. This happens over time.

Discussion

The answer as to why US beef is causing colorectal cancer and cardiovascular disease is directly related to the practice of using antibiotics as growth promoters. The use of antibiotics in the beef industry leads to a change in the gut flora in humans consuming this meat. Bacteria that can produce TMAO are now having the upper hand. In the US people produce more TMAO in response to beef consumption as the study mentioned has shown. The Japanese study cited above showed no sign of cardiovascular mortality when people consumed up to 100 gram (one serving) of meat per day over 16 years.

Antibiotics as growth promoters outlawed in Japan and Europe

The reason is that in Japan, as well as in Europe the use of antibiotics as growth promoters are illegal. When humans consume meat in Japan or Europe the original gut flora stays intact with no production of TMAO. Incidentally, the same is true for organic grass-fed meat in the US, which has no antibiotic residues in it. Recently there was a publication from Denmark that suggested to replace some of the beef consumption by low mercury fish.The authors of that study said that this will reduce mortality from cardiovascular disease.

Replace Red Meat And Processed Red Meat

Replace Red Meat And Processed Red Meat

Conclusion

A new study in the British Medical Journal showed that an increase in red meat consumption of only ½ serving per day for 8 years caused an increased mortality of 9% over the following 8 years. With regard to processed red meat the mortality was even bigger, namely 13%. The researchers replaced some of the meat with white chicken meat or vegetables and the mortality normalized.

In contrast, a Japanese study showed that there was no increase in cardiovascular disease with the consumption of up to 100 grams of beef or other meat products over 16 years.

Using antibiotics as growth promoters illegal in Japan and Europe

I pointed out before that there is literature explaining why there is a discrepancy: the beef industry in the US feeds the animals antibiotics as growth promoters. This changes the bowel flora in humans who eat the beef. The changed bacterial strains in the gut use carnitine from beef and make trimethylamine N-oxide (TMAO). This is a toxin that causes both cardiovascular disease and cancer. This explains why in the US beef is one of the culprits that causes heart attacks and colorectal cancer. In Japan this is not the case. Both Japan and Europe do not use antibiotics as growth promoters in the cattle industry as it is prohibited.

In the US it is likely safe to eat organic meats (beef, chicken) as these meats will not contain antibiotics. Due to the numerous additives in processed red meat, it is still a sensible idea to skip these products!

Both White Meat And Red Meat Elevate Cholesterol

A study from the American Journal of Clinical Nutrition showed that both white meat and red meat elevate cholesterol. This was a randomized controlled clinical trial. Many observational studies in the past showed that red meat consumption could elevated LDL cholesterol values and this increased cardiovascular disease. Many study authors have recommended to get away from the dangers from red meat by switching to white meat from poultry .

However, this study pursued this question in more detail. It questions whether it is true that white meat is safer from a cardiovascular risk point of view. It also studies the effects on cardiovascular risk when switching to vegetable protein (vegan or vegetarian diets). In addition, the researchers assessed the effects of low or high saturated fat on LDL cholesterol levels.

Design of the study

Researchers from the Children’s Hospital Oakland Research Institute, Oakland, CA conducted the study. They rotated participants through three different diets for 4 weeks each with a washout period of 2 to 7 weeks in between where they ate their usual foods. The diets were as follows. The first tract consisted of food with high-saturated fatty acids (high SFA): red meat; white meat and non-meat. The second tract contained low-saturated fatty acids (low SFA): red meat, white meat and non-meat. The researchers determined the cardiovascular risk of these 6 diets by measuring triglyceride levels, LDL cholesterol levels apo B levels ad additional factors.

Results of the study

LDL cholesterol: 2.64 mmol/L for red meat, high SFA; 2.61 for white meat, high SFA; 2.46 for non-meat, high SFA.

The LDL cholesterol values for red meat, low SFA were 2.35; for white meat, low SFA were 2.38 and for non-meat, low SFA were 2.22.

The message from this part of the trial is that it did not matter whether you ate red meat or white meat, the LDL cholesterol was still high, particularly when combined with high saturated fatty acids. Lean cuts of red meat and of chicken (no skin) result in lower LDL cholesterol readings. The very best LDL cholesterol results came from non-meat protein like vegetables. This was particularly so when the vegetables contained only low-saturated fatty acids.

There were many more results in the study, but it would be inappropriate to list them all for this overview here. For those interested in it, here is the link where more detail is discussed. Here is a blog where I discussed how to lower cholesterol.

Discussion of the study that found that both white meat and red meat elevate cholesterol

For years physicians have recommended to exchange some of the red meat (beef, pork and lamb) with white chicken or white turkey meat. This was based on poorly designed observational studies. Now the investigators of a randomized controlled clinical trial have shown that the old assumptions were incorrect. White meat raises LDL cholesterol just as much as red meat does. But protein from vegan or vegetarian diets lowers LDL cholesterol significantly. In addition the effect of saturated fatty acids raises LDL cholesterol significantly in all of the different diets. The researchers pointed out that L-Carnitine from red meat is metabolized by gut bacteria into trimethylamine-N-oxide (TMAO). This is a substance that has two effects on the body: it causes increased atherosclerosis (hardening of arteries) and also causes cancer of the colon.

Both White Meat And Red Meat Elevate Cholesterol

Both White Meat And Red Meat Elevate Cholesterol

Conclusion

This randomized clinical trial clearly showed that red meat and white meat cause the same elevation of LDL cholesterol and other cardiovascular risk factors. In contrast non-meat protein from a vegetarian or vegan diet lowers cholesterol. Also, high-saturated fatty acid food elevated cholesterol while low-saturated fatty acid food lowers cholesterol. For this reason, choose the leanest cut, if you eat red or white meat. Don’t be afraid to have a meatless day once or more often during the week. It will help you to equilibrate your cholesterol level. Keep in mind that your gut bacteria metabolize red meat into trimethylamine-N-oxide (TMAO). This is a substance that has two effects on the body: it causes increased atherosclerosis (hardening of arteries) and also causes cancer of the colon. For this reason keep your red meat consumption low, which prevents colon cancer, heart attacks and strokes.

Ultraprocessed Food Kills

The British Medical Journal published two papers that showed that ultraprocessed food kills. The first paper showed that highly processed food causes heart attacks and strokes. Another paper in the same journal showed that mortality is significantly increased when people consume highly processed food. Both papers were reviewed by CNN.

Food categories

Food questionnaires were administered over 24 hours every 2 years from every participant using the NOVA classification system.

There were 4 categories.

  • Category 1 consisted of “unprocessed or minimally processed” food. This included legumes, vegetables, fruits, milk, eggs, meats, poultry, fish and seafood, yogurt, grains and natural juice.
  • Next was category 2 of “processed ingredients”. This included salt, sugar, honey, olive oil, butter and lard.
  • Category 3 consisted of “processed foods“. This included breads, cheeses, beer, wine, and cured traditional ham and bacon.
  • Finally, category 4 consisted of “ultraprocessed foods”. This included sausages, flan, chorizo, mayonnaise, pizza, cookies, potato chips, chocolates candies, artificially sweetened beverages including whisky, gin and rum.

Study on cardiovascular risk

A study from France followed more than 105,000 people for 5.2 years. The participants filled out food questionnaires every 6 months. The foods consumed were classified according to the NOVA categories. The results showed that the men’s diet consisted to 17.6% of heavily processed foods while the diet of women consisted of 17.3% heavily processed food. Each 10% increment of highly processed food (called “ultraprocessed” food) had an association with 12% higher risk of cardiovascular disease, 13% more heart attacks and 11% more strokes. The researchers could also show that a decrease in ultraprocessed food was leading to less percentage of these diseases.

Mortality risk when consuming ultraprocessed food

A similar study involving close to 20,000 participants in Spain that had a long observation time of 15 years (from 1999 to 2014). The 4 food categories were as mentioned above.

A person eating more than 4 ultraprocessed items per day or more had a 62% increase of death rate in comparison to those who ate processed food less frequently. Each additional ultraprocessed food item added another 18% of mortality risk. Maira Bes-Rastrollo, professor of Preventive Medicine and Public Health at Universidad de Navarra, Medical School said: “These results are in agreement with other recent results based on populations in France and the United States. If all the different study results align, despite the separate research groups using dissimilar populations, diverse age ranges and different methodologies, then this lends support to a possible cause-effect relationship between ultraprocessed foods and poor health.”

Discussion

You may remember that your grandparents reminded you not to eat “junk food”. Often junk food is consisting of ultraprocessed foods. Both of these independent studies from France and from Spain have shown that there is a significant risk of heart attacks and strokes associated with the consumption of ultraprocessed foods. In addition, there is also a significant mortality risk when you consume ultraprocessed food. The key is to learn from this and cut down on processed foods; instead eat foods that are less processed and are wholesome for you. Eat vegetables, fruit, nuts and stay away from the grocery store’s shelves with processed foods.

Ultraprocessed Food Kills

Ultraprocessed Food Kills

Conclusion

What your grandparents used to tell you about processed foods is now available as two separate publications from the British Medical Journal. The less processed food you consume, the healthier your food intake is. You will enjoy better health. This is the simple message. Avoiding ultraprocessed food will help you to avoid heart disease, heart attacks and strokes. In addition you will have a longer life expectancy.

Replacing Part Of Red Meat With Fish Shows Health Benefits

A Danish study has shown that replacing part of red meat with fish shows health benefits.

The research was done by a PhD student and pointed out that men above the age of 50 were particularly benefitting from fish substituting part of red meat in their diet. Women in the childbearing age also benefitted greatly. On this diet pregnant women as well as the unborn children become healthier.

Risk versus benefit analysis

Sofie Theresa Thomsen, the PhD student who conducted this study did risk-benefit assessments regarding partial substitution of beef with low-mercury fish. Red and processed meat contains saturated fat, which is added to the other saturated fat in the Danish diet. Red meat and processed meats have been associated with colorectal cancer and some other cancers. But red meat also contains beneficial iron. In contrast, fish contains a lot of omega-3 fatty acids that are anti-inflammatory and also contains vitamin D. But one has to be careful about methylmercury content in fish. I reviewed fish, mercury contamination and the benefits in this link.

In her calculations Sofie Theresa Thomsen replaced 350 grams of beef per week with 350 grams of low-mercury fish per week.

If all the Danish households would do this partial beef/fish exchange, the Danes would gain 7,000 healthy years of life annually. This includes, among other health conditions, the prevention of 170 deaths from coronary heart disease.

What kind of fish can you eat?

As the link above shows, there are low, medium and high methylmercury contaminated fish. The higher the fish is in the predator chain, the higher the methylmercury content. This is of particular concern for pregnant women as mercury is toxic for the fetal brain tissue. But they consume low mercury fish and shellfish, like mackerel, herring, wild salmon, shrimps or clams, pregnant women benefit greatly from the beef/fish exchange. Tuna is too high in methylmercury to be included in the beef/fish exchange. If you were to include tuna in this, you would experience a health loss.

Vitamin D and iron

The study showed further that a partial exchange of beef by fish would reduce the number of Danes who are vitamin D deficient. The 350 grams of fish per week are sufficient to significantly raise the vitamin D blood level. Conversely, replacing a part of the beef intake with fish does not cause iron deficiency problems.

Who benefits most from replacing part of red meat by fish?

Sofie Theresa Thomsen asked who would benefit most from such a beef/fish exchange diet.

On the one hand it is the older than 50 year male population who is at a significant risk of developing heart attacks. The fatty fish with omega-3 fatty acids reverses some of the plaque in the arteries and keeps coronary arteries open. This prevents heart attacks and strokes.

On the other hand pregnant women and their children benefit greatly from the beef/fish exchange diet. The women will feel more energy and their offspring will have healthy brains.

Conclusion

A study from Denmark analyzed what happens when a person exchanges 350 grams of beef with low mercury fish or shellfish per week. The conclusion was that Danes would gain 7,000 healthy years of life annually. Among these is the prevention of 170 deaths from coronary heart disease. But the most lives saved would be among men older than 50 years due to heart attack and stroke prevention. Pregnant women are also benefitting tremendously, not only for themselves, but for their children. The fish needs to be low mercury fish, as mentioned above, as mercury is a central nervous system toxin. Tuna is too high in mercury.

I have cut out red meat and meat products from my diet since 2015, when the WHO came out with the statement that red meat causes colorectal cancer. As a result I eat a lot more low mercury seafood and shellfish.
