Beef and Dairy May Cause Cancer and MS

By | autoimmune disease, Cancer, colorectal cancer, immune system, Multiple sclerosis, red meat

New cancer research suggests that chronic virus particles in beef and dairy may cause cancer and MS (multiple sclerosis). The Medical journal Medscape.com had a review article that summarized this line of research.

Papillomaviruses and cervical cancer

Harald zur Hausen, M.D., D.Sc., a German virologist, detected that papillomavirus causes cervical cancer. He was given the Nobel prize in Medicine in 2008 for “his discovery of human papillomaviruses causing cervical cancer”. In the meantime, we know that there are two strains, namely HPV-16 and HPV-18 that are carcinogenic. We also learnt that papillomavirus causes oropharyngeal cancer, anal cancer, penile cancer and vulvar cancer. Since then, HPV vaccines are commonly in use for cancer prevention.

Evidence for causation of colorectal cancer

Professor Harald zur Hausen and his wife, Professor Ethel-Michele de Villiers, continued work on looking for viral particles in many other cancers. This led them to state that colorectal cancer was due to a latent viral infection. He determined that, when women were breastfeeding their infants for prolonged periods of time (about 1 year), they transmitted oligosaccharides with the breast milk to their offspring, which gave lifelong prevention against colorectal cancer to their children. He also showed that colon cancer patients had round particles in their intestinal mucous membranes, which consisted of single-stranded DNA rings.

Persistent viruses

The researchers said that they came from viruses and they named them bovine meat and milk factors (BMMF). In the same areas in the intestine, they detected acid radicals from oxidative stress typical for chronic inflammation. They postulated that infants who are weaned from breast milk prematurely, and started on cow milk formulas ingest BMMF. This infects the lining of the gut where a chronic subclinical BMMF infection gets established. Decades later the patient comes down with colorectal cancer. They established that children who are breast fed for 1 year do not get BMMF particles in the lining of their guts or colorectal cancer. They also don’t get MS in adult life.

Criticism of two regulatory agencies in Germany

The above results of professor zur Hausen and his wife were published in February of 2019. This led to a lot of press releases questioning these results. In Germany the consumption of beef and milk products is popular. The DKFZ (Deutsches Krebsforschungszentrum) felt that an “all-clear signal” was necessary. The Bundesinstitut für Risikobewertung (BfR) stands for the German Federal Institute for Risk Assessment, situated in Berlin. It is a substructure of the German government responsible for food safety. The second agency is the Max Rubner Institute (MRI) in Karlsruhe, also known as Federal Research Institute of Nutrition and Food. Both agencies started to investigate the facts of Prof. zur Hausen’s research. At the end of November 2022 the BfR and MRI made a joint statement. They stated the following:

  • BMMF were not new viral agents, but variations of already known DNA sequences.
  • BMMF commonly occurred in a variety of animal- and plant-based foods.
  • BMMF were not capable of infecting human cells.
  • It was true that consumption of red and processed meat correlates with the incidence of intestinal tumors.
  • However, consumption of dairy products are linked to a reduced risk of intestinal tumors.
  • There is no evidence that breast cancer would be associated with the consumption of beef or dairy.
  • They stated that milk products and beef are valuable supplementary diet components for infants due to their micronutrients. They further stated that dairy and beef products are safe for people of all ages.

Evidence for causation of multiple sclerosis

Professor zur Hausen and his wife, Professor Ethel-Michele de Villiers both worked at the German Cancer Research Center in Heidelberg. They pursued research about MS. MS is usually attributed to IgG1 and IgG3 autoantibodies that destroy Schwann cells. The Hausen research team found the following perplexing facts:

  • MS was associated with the consumption of dairy products and beef products.
  • They isolated ring-shaped DNA molecules (BMMF) from dairy and cattle blood.
  • Epstein Barr virus (EBV) also plays a role in initiating MS. MS patients have higher antibody titers against EBV.
  • One research paper noticed that MS patients in Antarctica secreted EBV in their saliva in the winter month. However, vitamin D3 stopped the viral excretion. This is very interesting as vitamin D is an important immune response stimulator.

More evidence:

  • They isolated BMMF particles from lesions of MS patients.
  • They noticed the old fact that MS is more common further away from the equator. Vitamin D production from sun exposure reduced cases of MS.
  • Prolonged breast feeding up to one year prevents life threatening rotaviruses and noroviruses in the newborn. The reason is exposure to oligosaccharides in breast milk. The mother starts producing breast milk in the middle of her pregnancy. It protects mother from tumors (including breast cancer), from MS later in life as well as type 2 diabetes.
  • The researchers formulated the hypothesis that both EBV and BMMF are responsible in patients to form MS lesions in the brain when vitamin D levels are low. A good dose of vitamin D3 every day may be helping to keep EBV and BMMF in a dormant phase.

Discussion

At this point there is no consensus why an increased consumption of beef and processed meat causes more colorectal cancer. The question is whether BMMF particles cause colorectal cancer or whether meat consumption experiences metabolization into carcinogenic substances? Either way it would be desirable to cut down on your red meat consumption.

With respect to MS, we know that autoantibodies are destroying the Schwann cells. But the question is why the immune system produces autoantibodies. Could it be that persistent EBV viruses switch the immune system from a normal to an autoantibody mode? Would BMMF be an additional factor?

Conclusion

Professor zur Hausen, a virologist from Germany and his wife Professor Ethel-Michele de Villiers researched persistent viruses. Professor zur Hausen detected the connection of papilloma viruses to cervical cancer. He received the Nobel prize in medicine 2008. They proposed the theory that newborns in their first year of life have an immature immune system. If they are fed cow’s milk and/or beef during the first year they accumulate bovine meat and milk factors (BMMF), which can subsequently lead to colon cancer or to MS as an adult. Two top German institutes banded together to criticize Prof. zur Hausen’s research.

Criticism of Professor zur Hausen’s research

The Bundesinstitut für Risikobewertung (BfR) stands for the German Federal Institute for Risk Assessment, situated in Berlin. It is a substructure of the German government responsible for food safety. The second agency is the Max Rubner Institute (MRI) in Karlsruhe, also known as Federal Research Institute of Nutrition and Food. These research institutes concluded that not all of the findings of Professor zur Hausen were valid. I listed 7 of their concerns. On the other hand, they agreed that it was true that consumption of red and processed meat correlated with the incidence of intestinal tumors. Time will tell which parts of the research ultimately will be valid and which are not.

Tick Bites Can Render You Allergic to Red Meat

By | Allergies, anaphylactic reaction, immune system, red meat

Tick bites can render you allergic to red meat. This comes from the alpha-gal syndrome, which is a type of food allergy. It is a tick with the name of Lone Star tick that transmits this syndrome in the southeastern United States.

Deer carries the Lone Star tick into other parts of the US. The bite of the tick transfers a sugar molecule called alpha-gal into the person’s body. Subsequently the person develops a sensitivity to red meat, like beef, pork and lamb. Red meat membranes are rich in the sugar alpha-gal. The allergy can also be directed against other mammal-related products like milk protein. Often the person is unaware of this type of allergy, alpha-gal syndrome. In this case people continue to get exposed to red meat and mammal products, and the immune reactions become more severe over time. Anaphylactic reactions that are not due to food allergies have a high probability to be due to alpha-gal syndrome.

More details about the alpha-gal syndrome

Alpha-gal is the abbreviation for Galactose-alpha-1,3-galactose, which is a carbohydrate. It is part of most mammalian cell membranes, except for primates. The immune system in humans recognizes it as a foreign body and produces anti-alpha-gal antibodies. It is the bite of the lone star tick in North America or the castor bean tick in Sweden that can start the allergy to alpha-gal. If a person has frequent anaphylactic reactions, the physician should think of alpha-gal syndrome, which could be the underlying cause.

Sensitization of the human host

When the lone star tick bites mice, rabbits or deer it takes up alpha-gal sugar. Subsequently, when the tick bites a human, the alpha-gal sugar is injected into the human host together with its saliva. This alarms the immune system and antibodies are produced. When the human host later consumes meals with red meat, the body reacts to the previous sensitization to alpha-gal sugar by the tick bite. The antibody response to alpha-gal sugar from further red meat meals becomes even stronger than before. The only relief for human host from immune reactions is to switch to a diet that is free of red meat.

Allergic symptoms

The alpha-gal allergy can manifest itself by skin rashes, welts, skin itchiness, swelling, shortness of breath, headaches, belly aches, diarrhea and vomiting. In serious cases an anaphylactic reaction can occur, which in some cases can be lethal.

Protein allergies versus carbohydrate allergies

Until 2009 medical science believed that allergies would only be due to proteins. One such example are allergic reactions to peanuts. It is the peanut protein that can cause allergies. Subsequently, the alpha-gal allergy became known, which involves the sugar galactose-alpha-1,3-galactose. This was the first sugar molecule that researchers could demonstrate to mount an allergic reaction, from which the human host could turn sick.

Tick Bites Can Render You Allergic to Red Meat

Tick Bites Can Render You Allergic to Red Meat

Conclusion

The Lone Star tick in the southeastern US carries the sugar galactose-alpha-1,3-galactose (for short alpha-gal) which originates from bites of mammals that are not primates (cattle, pigs and lambs). When the tick bites a human, the immune system produces antibodies against alpha-gal. This can produce skin rashes, welts, skin itchiness, swelling, shortness of breath, headaches, belly aches, diarrhea and vomiting. But when the person recovers from the tick bite, a lifelong sensitivity against reed meats remains. Every time a sensitized person consumes a red meat meal the same symptoms, as originally experienced from the tick bite, return.

Abstinence from red meat

The only remedy for the alpha-gal syndrome is to abstain from red meat. The cell membranes of the muscle of red meat contain the sugar alpha-gal. Seafood, chicken, eggs and turkey meats are OK for consumption. But the patient has to be diligent about not making any dietary mistakes. If intermittent red meat exposure continues, a more severe allergy can develop. These have the name of “anaphylactic reactions”, where the patient is in danger of suffocating or even die from it.

Moderate Carb Intake Has The Lowest Mortality

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

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

Research study finds moderate carb intake has the lowest mortality

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

Plant-derived versus animal-derived fat and protein

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

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

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

Other studies comparing the effect of animal protein versus plant protein

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

 

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

Triglycerides are an independent risk factor for heart attacks

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

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

Regular exercise prevents disease and premature deaths

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

Discussion

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

Moderate Carb Intake Has The Lowest Mortality

Conclusion

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

The healthiest diet

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

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

Early Alcohol Use Will Result In Memory Loss Later In Life

By | Cancer, Health, Heart Disease, High Blood Pressure, Prevention, Substance abuse, Vitamins and supplements

Researchers found that heavy alcohol use in males during midlife paves the way to memory loss from dementia later in life.

I thought that this would be a good topic to review the effect of alcohol in general. Alcohol is a known cell poison, yet cardiologists keep on referring to the beneficial effects of that 1 glass of wine per day that will prolong your life. I will attempt to explain these diverse effects, where small amounts are supposed to be good for you while high amounts can be very damaging.

Review of the effects of alcohol

50% of the world population drinks alcohol, 10% to 20% have chronic alcoholism (Ref.1).  Just recently a Guardian news study was released showing that an astounding 25% of Russian men die before reaching the age of 55, compared to only 7% of men in the United kingdom and less than 1% of men in the US. The study looked at the effects of consuming large amounts of vodka.  There are about 10 million chronic alcoholics in the US. Chronic alcohol consumption leads to 100,000 deaths every year in the US. More than 50% of these deaths are from traffic accidents, the rest from medical problems caused by alcohol (Ref.1). Most of the alcohol gets detoxified through the liver cells and is metabolized into acetaldehyde. This involves the cytochrome P-450 system. That means that when a person also takes narcotics, sedatives or psychoactive drugs that are also metabolized through this liver enzyme system drugs and alcohol are taking much longer to be metabolized. This can lead to lethal overdoses that we hear about on TV all the time, hence the warning that you must not mix alcohol with drugs.

Early Alcohol Use Will Result In Memory Loss Later In Life

Early Alcohol Use Will Result In Memory Loss Later In Life

Alcohol is a cell and nerve poison. The most vulnerable organs in the body are the liver, brain, heart, pancreas, bone marrow and stomach. So, here are a number of conditions caused by drinking alcohol:

a)    Anemia: When a person drinks heavily and regularly anemia shows up in a blood test. Alcohol has a toxic effect on the bone marrow, which interferes with the production of red blood cells. But certain vitamins required by the bone marrow to manufacture red blood cells are often also missing in the diet of an alcoholic, which contributes to anemia as well.

b)    Cirrhosis of the liver develops in 10% to 20% of heavy drinkers. With cirrhosis part of the liver cells get replaced by fibrotic tissue and in advanced cases this can lead to a hepatic coma and death. Others are developing alcoholic hepatitis. This is an inflammation of the liver with fever and jaundice where the skin and eyeballs turn yellow. It is associated with severe abdominal pain.

c)    Gastritis: Alcoholic gastritis is common, but often undetected. The affected individual may just have stomach pains for a few days, or vomit food and/or blood in addition. With continued use of alcohol it may turn chronic. Alcoholic gastritis can turn into gastric ulcers with massive bleeding that often lead to death.

d)    Pancreatitis: The pancreas is a particularly vulnerable glandular tissue, which gets damaged by regular alcohol intake and with chronic alcohol intake gets partially replaced by fibrotic tissue causing the feared and painful chronic pancreatitis. This is a condition with vomiting and severe abdominal pains that can be unrelenting.

e)    High blood pressure, seizures, dementia, depression, heart irregularities and nerve damage:

You may ask yourself how all of these conditions would be reasonably under one heading. The heading for this is “nerve damage”. Let me explain: The sympathetic nerve is very sensitive to alcohol toxicity and when the sympathetic nerve fibers are damaged, you will develop high blood pressure. You see your physician, get blood pressure medication, but the pressure is difficult to control, if you continue to drink alcoholic beverages. It does not make sense to just add blood pressure pills and hope that this will cure your problem. Seizures are due to direct nerve damage in the more sensitive parts of the brain, which will cause these areas to produce extra electrical activities, which we call seizures. Again, just treating with anti-seizure medications is not the solution. Avoidance of alcohol is the other part of the treatment schedule. Dementia from heavy alcohol use is due to direct nerve atrophy in the brain. Our brain shrinks normally 1.9% to 2.8% per decade, depending on which research papers you read. But in the presence of heavy drinking the frontal lobe of the brain is particularly vulnerable to brain shrinkage.

As this publication shows, mild and moderate drinkers did not suffer more frontal lobe shrinkage than abstainers, but heavy drinkers had a 1.8-fold higher risk of frontal lobe shrinkage on average when compared to abstainers. It was calculated that alcohol had contributed 11.3% to that frontal lobe shrinkage.

The rest of the toxic effect on the nerve tissue explains why depression would develop. The frontal brain contains most of the serotonin producing nerve cells. When serotonin-producing nerve fibers get damaged, the body does not produce enough serotonin to prevent depression from setting in; GABA producing cells often also get damaged, which causes anxiety. It’s not good enough to just prescribe anxiolytic drugs to which the patient will get addicted. The whole person needs to be treated, and abstinence from alcohol has to be part of the program.

Heart irregularities (atrial fibrillation, ventricular fibrillation) can be life-threatening complications due to the toxic effect of alcohol on the nerve fibers within the heart muscle. Emergency physicians are aware of the connection of these conditions to alcohol consumption. Some people’s hearts are more sensitive to the effects of alcohol than others. The most common cause of temporary atrial fibrillation is excessive alcohol intake (holiday heart) according to Ref. 2.

Finally there is the effect of alcohol on nerves in the body. This explains that heavy alcohol consumers can come down with painful pins-and-needles sensations in their hands and feet or with numbness or loss of muscle strength. When the parasympathetic nervous system is affected embarrassing incontinence or constipation can result. Erectile dysfunction in men is also very common. Viagra and continuing to drink is not the solution.

f)      Gout: This painful formation of uric acid crystals in joints can be precipitated in sensitive individuals by consuming alcohol in combination with eating large helpings of beef. There may be a history of gout in the family. Treatment for this is to refrain from alcohol and avoid foods that are leading to uric acid production when ingested.

g)    Cancer: When the body detoxifies alcohol in the liver, the breakdown product is acetaldehyde, which is a known cancer producing substance. A whole array of cancers are known, which come from heavy, chronic alcohol consumption: cancers in the mouth, larynx, esophagus, stomach, pancreas, liver and colorectal cancer have all been linked to excessive alcohol intake.

h)    Cardiovascular disease: heart attacks and strokes can be caused particularly by binging; it is thought that binging makes platelets from the blood more sticky so they clump together and cause blood clots, which in turn leads to heart attacks and strokes.

i)      Infections: Alcohol weakens the immune system, which is another effect on the bone marrow similar to causing anemia, except that this is the toxic effect on the white blood cells and lymphocytes. Heavy alcohol consumers are more prone to pneumonia, to HIV, sexually transmitted diseases, and tuberculosis.

Cardiology view of preventative alcohol

Despite all of these hair raising toxic effects cardiologists have painted the rosy picture that 1 glass of wine for women and 2 glasses of wine for men per day will prevent heart disease. What is the true story here?

Ref.2 points out that there are about 100 prospective studies that confirm that there is an inverse relationship between mild to moderate alcohol consumption and “heart attack, ischemic stroke, peripheral vascular disease, sudden cardiac death, and death from all cardiovascular causes”. It describes further that the reduction of risk in these various studies was persistent and consisted of a 20% to 45% risk reduction. Using blood tests investigators have found that this is because of an increase of HDL cholesterol, reducing blood clotting, making platelets less sticky and reducing inflammation as evidenced by a reduction of the C-reactive protein. Further research has pinpointed that it is the phenols and resveratrol that are contained in alcoholic beverages that are responsible for the beneficial effects. The bad news is that three glasses of wine or more do the opposite, so does binge drinking. Unless you are extremely disciplined and never increase your allowed limit (1 drink for women, 2 drinks for men) you will CAUSE heart disease rather than PREVENT it (Ref.2). Some people have a family history of breast cancer or colon cancer and they should avoid alcohol altogether; also people coming from alcoholic families should avoid alcohol.

Conclusion

Where does this leave us with regard to prevention of heart attacks, strokes and hardening of the arteries in the legs (peripheral vascular disease)? If you are disciplined and stick to the limits, you could prevent 20% to 45% of cardiovascular risk. The brain study mentioned in the beginning of the blog would also confirm that there was no difference between dementia or brain shrinkage when mild to moderate drinkers were compared to abstainers over 10 years. What is not told by the wine industry is that the same effects that prevent cardiovascular disease in mild to moderate drinkers can also be achieved by natural means: exercising regularly will raise your protective HDL cholesterol; taking ginkgo biloba, flax seed and omega-3 fatty acids thins your blood and the platelets are getting less sticky; omega-3 reduces inflammation and resveratrol elongates telomeres making you live longer. At the A4M conference in Las Vegas in December 2011 there were three speakers who pointed out that even small amounts of alcohol will poison mitochondria of your cells and interfere with normal hormone action. This was enough to make me join those who abstain alcohol completely. One thing has not yet been investigated in long-term studies, namely how small effects of alcohol may affect the body over several decades and over an entire lifetime. Despite all the promises of interest groups that red wine is a trendy drink for those interested in heart health, the fundamental long-term studies are missing. What does a guy do with a healthy heart and a brain that is not functioning too well? I just do not want to be the guinea pig in that worldwide study.

Airplane Food And Airport Food, A Personal Travel Experience

By | Diabetes, Health, Heart Disease, High Blood Pressure, Nutrition, Prevention

Travelling for pleasure is usually something we eagerly anticipate: it can associate with a long wished for vacation, meeting family and friends, enjoying a different environment, in short: there is a bit of adventure attached to it.

Getting something to eat while you are in transit, however, can be a different story. Let me share a recent experience that my wife and I had on a transcontinental flight.

We had to get up shortly after 4 AM, and knowing that we would be in transit till later that evening we decided to prepare an early breakfast. As we usually do, we packed some plastic bags with travel snacks and stashed them away into our back packs: walnuts, almonds, apples, some cheese, some hard boiled eggs and a chocolate bar (70 % cocoa) for an indulgent dessert. It felt a bit unusual to sit down to a vegetable omelet, enjoy some berries and nuts and fix a cup of Americano at 5 in the morning, but we got over the early hour and enjoyed our breakfast. It was a good start to cope with a three-hour time switch that awaited us at the end of the trip.

After checking in at the airport we were greeted with the pleasant news, that our seat arrangement had been upgraded: we would travel first class, as they could not accommodate us in economy. To complete the sense of unexpected luxury, a full breakfast would be included. We did not expect any gourmet fare, but it was welcome news. After some time the flight attendants started to serve the meal. The choices were a cereal bowl or a scrambled egg skillet southwestern style for breakfast. My readers know already that I do not hold the breakfast cereal in high esteem. Cereal has the undesirable effect of sending blood sugar levels to unhealthy highs and as a result causing insulin spikes, so it is not a prudent choice in the first place. We asked for the scrambled eggs, cautiously enquiring: ‘What is in it?”

Airplane Food And Airport Food, A Personal Travel Experience

Airplane Food And Airport Food, A Personal Travel Experience

We were informed that it would be scrambled eggs with some black beans, green and red peppers, ham, onion and some cheese. It sounded really good, and we felt like a glutton having eaten a substantial breakfast at home and now getting some more! It turned out to be a bit different. The meal arrived. It was a flat skillet dish, which consisted of a thick layer of potato cubes held together by a yellow substance, which could not really be described as scrambled eggs. About half a dozen cubes of peppers were identifiable along with a few black beans. I started mining for onions and ham and tried to dig out the egg. It was virtually impossible! The amount of egg that I could retrieve was not more than 1 level tablespoon, and there were a few tiny specks of ham. My wife had the same experience. Needless to say, the skillets were almost full of potatoes, when we sent them back. The flight attendant came through one more time and offered a basket of croissants and buns to complete the breakfast, which we politely refused. As you see, we did not have any need to feel guilty about ingesting a second breakfast onboard, as this meal was simply unsuitable for anybody who was seeking balance in nutrition. To make it short: it is almost exclusively overfeeding the consumer with a load of dense carbohydrates (potatoes, croissants and buns), neglects a sensible amount of protein, and omits any healthy fat source. Out of sheer curiosity I flicked through the pages of an in-flight magazine that listed the foods that could be purchased on board for lunch. The results were not inspiring. There was an assortment of snack foods: potato chips, pretzels, super-size chocolate chip cookies, a candy bar that I had met before on TV and beef jerky. The meal selection featured three types of sandwiches: ham and cheese, brie and turkey breast, and a “loaded” super Italian affair with salami, which looked like a guarantee to a case of indigestion. The cheese plate was sold out and the fresh fruit plate was gone too. Sorry, no luck! As a matter of fact we were lucky and so were all the other passengers who came prepared with a stash of travel foods. When we got hungry towards noon we dug out our travel snacks, drank some water and were quite satisfied.

On our return trip, we traveled economy class (no upgrade to first class food or first class seats this time). It was another lengthy trip coast to coast, and as there were two lengthy layovers, the day was even longer. We arrived at one international airport at the East coast by lunchtime. This time we decided to get a meal at one of the numerous eating establishments. After all, just recently news articles had praised airport restaurants having embraced many healthy food choices. So this would not be airplane food but REAL food! We had some time to walk around and explore, and it turned out, that we certainly needed it! We salivated at the sight of a choice of mahi-mahi with a mixed salad at one café. Cautiously we wondered whether this would be grilled fish. No, we were told, this would be breaded and deep-fried! And it would not be offered in any other way. Too bad, this was not really what we wanted! An Asian food outlet offered a buffet-style assortment of food. It did look very good, and we loved the chicken and vegetable choice or the beef and broccoli with mushroom dish. It did look fresh and appetizing. Often Asian foods can contain MSG. We wanted to make sure that this substance would not be in the food at this place. Sorry, we were told, all the meats and vegetables did contain MSG! Monosodium glutamate is not a harmless flavor enhancer. It belongs into the group of excitotoxins. The substance can destroy brain cells. It also has the potential to give you a nasty headache, especially if larger quantities are used. We were looking for food minus a headache, so we walked away once again and looked for more. An Italian bistro offered the usual suspects: piles of pasta and pizza! And there was a bakery with towering-high tortes, cinnamon buns, and muffins. It was overfeeding of the already carbo-holic individual and under nourishing the traveller. Sad!

After this expedition through the terminal we did finally find a meal that would sustain us until the evening. It was a pre-packaged Thai salad. It was certainly nothing fancy, but it contained a large amount of lettuce and other salad vegetables, offered a small but appropriate amount of cooked shredded real chicken, not some processed salty fake meat, and a small container of salad dressing on the side. It was enough to feel pleasantly full without feeling stuffed and good enough to keep us going till the evening.

Yes, we really wanted a touch of luxury for dessert! We thought of the duty free shop and envisioned a square or two of sinfully dark chocolate. Actually, this is not sinful at all! Have a piece of chocolate with over 70 % cocoa content or even 85%. It is not bitter, but an explosion of flavor on your taste buds, and it happens to be a source of anti-oxidants and bioflavonoids. It lowers high blood pressure and gobbles up free radicals, and as a result it can protect you from heart disease. One word of caution: use moderate amounts! Two or three squares only, not more, please!

And there was chocolate at the duty-free shop, lots of it! There were praline selections in large varieties, and there were Lindt and Ghirardelli chocolate bars, two well-known brands! We rejoiced…but too early! There were six packs featuring extra-creamy, sea-salt, caramel, chocolate and chili. As we studied the labels it was very obvious, that this was not at all what we were looking for! One bar in six was of excellent quality with a high cocoa percentage. The rest was a “gourmet mix”, all of them with low cocoa percentage and high sugar content, which really means it was useless. Were we willing to waste our money on half a dozen chocolate bars of which just one single bar was the merchandise we wanted? The answer was no! And of course, the package could only be sold this way; sorry, no choice! After leaving the duty free store with all its high-class brands behind, we found a humble news and magazine outlet. It had nice, entertaining reads to shorten the next leg of our journey. And-what a surprise! There was a stack of chocolates by an unknown European manufacturer with an 85 % cocoa content. Lucky us! An interesting magazine and dessert too! Bon voyage!

Conclusion

We do not think that we are the only health conscious persons on the planet. We hope that someone in charge in any airport or in an airline catering company smells a business opportunity. We are not demanding. We just prefer healthy foods and it would be great to find a meal choice with whole foods such as greens, vegetables, wild salmon, organic chicken, or grass-fed antibiotic-free beef. There is no need for anything elaborate. It’s really back to the basics! Even a mixed salad with a healthy protein portion would fit in very well. It is time that not just a few high class chefs around the world take notice of the new changes of a healthy diet that I summarized in this blog recently: “Buying Into High Carb, Low Fat Myth Makes You Sick”. In case you want to read more, I am in the process of publishing a book, which also contains 7 days of healthy menus at the end of it. It will be published early in 2014 through Amazon.com and is entitled: “A Survivor’s Guide To Successful Aging” (addendum Nov.7, 2014: It has been published March 31, 2014).

Changes Of Gut Bacteria Can Cause Heart Attacks

By | Cancer, Health, heart attack, Heart Disease, Prevention, Stroke, Vitamins and supplements

The recent news of gut bacteria possibly being involved in causing heart attacks (see details below) sounds pretty outrageous. In order to make this more understandable, we need to start backtracking how bacteria end up in our gut and what they are doing there.

Gut bacteria in our bowels at various stages in life

Even among infants there is a huge difference in the composition of the gut flora depending on whether the baby was vaginally delivered, born by Cesarean section or prematurely born and nursed in an intensive care unit for a prolonged period of time.

When we are grown up, it depends on where we live on our planet as to what type of gut flora we have. A 2011 study of the bacterial composition of stool samples in Europe versus Africa showed that the European microbiome in the colon was typical of the Bacteroides enterotype, whereas the African microbiome was dominated by the Prevotella enterotype. Other studies have shown that the type of diet we eat causes us to harbor different types of gut flora. A person eating a more vegetarian diet will have a Prevotella enterotype gut flora, while another person eating a Western style fat and protein dominated diet will have a Bacteroides enterotype gut flora. What is the gut flora doing? It lives within our gut for our mutual benefit. We provide the gut bacteria a comfortable home at body temperature where they grow best. They in turn ferment undigested foods, protect us from the growth of harmful bacteria, produce vitamins like vitamin K and biotin, and produce hormones that direct the body to store excess food as fat.

Cleveland Clinic’s gut flora research linked to heart attacks

In April 2013 reports that heart attacks may be related to the composition of your gut flora hit the popular press, articles like this. Two years earlier, in April of 2011, the same Cleveland research group under Dr. Stanley Hazen found that the gut flora composition has an impact on heart disease. They stated that a “byproduct called trimethylamine N-oxide (TMAO) is produced when intestinal bacteria digest the nutrient phosphatidylcholine, commonly known as lecithin”. It was determined that the liver was responsible for producing TMAO out of absorbed materials from gut bacteria and that this was responsible for accelerating hardening of the arteries, which in turn caused deadly heart attacks and strokes.

As can be seen from this link the Cleveland research group is suggesting that TMAO could become a valuable screening tool when measured in patients’ blood to screen for their risk to develop a heart attack or stroke in the future. Furthermore, once these patients are identified, they can be sent to a dietitian and be put on a different diet that prevents heart attacks and strokes; also, the progress could again be monitored through repeat TMAO blood tests down the road.

Criticism of research from the Cleveland Clinic

Not every one has welcomed the study as clear-cut proof for a link between the gut flora and heart attacks, strokes and deaths. This link shows that it is questioned whether perhaps low antibiotic residues in red meat would explain the findings of the study. It rightly points out that there was no control for whether the more than 4000 patients were eating organic foods or a regular American diet. The comment goes on to say that the regular American diet contains residual antibiotics from milk, milk products, beef, chicken and turkey. These traces of antibiotics are powerful enough to have an effect on the gut flora, which likely is the reason for the differences between the vegetarian diet versus a Western style fat and protein dominated diet. It is entirely possible that grass fed beef would not lead to TMAO levels in the blood whereas regular beef or hamburger meat will raise the TMAO levels. The same could be true for egg consumption, which was also accused of raising TMAO levels. However, we do not know whether organic eggs that do not contain antibiotics would have done the same as regular eggs that contain traces of antibiotics.

Cancer caused by gut flora

This 2008 review article explains how lactobacillus and bifidobacteria (probiotics) prevent colon cancer, while bacteria of the Bacteroides and Clostridium variety increase the incidence of colon cancer and the growth rate of colonic tumors. So, the composition of your gut flora does not only matter with regard to prevention of heart attacks and strokes, but is also important in preventing colon cancer.

Change your gut flora to boost your health

Here is where the “rubber hits the road”. What I mean is that you can benefit from all of this research with regard to your health by paying attention to a few facts and possibly making a few changes as follows.

  1. I think that the argument of the bulletproofexec.com website holds true and we should all eat organic meats whenever possible. The Cleveland study has already shown that the gut flora in vegetarians stayed healthy even when they occasionally slipped and ate a regular steak.
  2. Take supplemental probiotics from the health food store. It will improve your gut flora within a day or two.
  3. Higher intake of fruit and vegetables make a measurable difference in the body decreasing the risk for heart attacks and strokes as this British research group has shown. Another research group from Italy has confirmed that an increased intake of fruit and vegetables mobilizes genetic switches that will stabilize the metabolism of the gut wall and prevent cancer of the colon.

So, the verdict for boosting your health is out: eat organic foods, use probiotics as supplements and eat more fruit and vegetables!

Red Meat Linked To Heart Disease In Diabetics

By | Diabetes, Heart Disease, Nutrition

Red meat is one of the sources of protein, but doctors from the Harvard School of Public Health reporting in the January edition of Diabetes Care, that a type 2 diabetes diet should be lean in red meat.

Type 2 diabetics are at risk for subsequent coronary heart disease (CHD), and intake of iron rich food was significantly associated with a greater risk of fatal CHD. The results come from a prospective study of 6,161 women from the Nurses’ Health Study. All of these patients reported a diagnosis of adult onset diabetes, and they were followed between 1980 through 2000, which amounts to an impressive 54,455 person-years follow-up. Attention was paid to the food questionnaires, which were monitored for the consumption of iron and red meat such as beef, pork or lamb as a main dish, also for the use of beef in roast beef sandwiches and mixed dishes, hamburger, hot dog, processed meat and bacon. Note was also taken of other nutrients such as seafood and poultry.
Women with diabetes who ate the most iron in the form of heme found in red meats had a 50% increased risk of total coronary heart disease as compared to those with the lowest intake. The risk ratio with women was more obvious in post menopause when compared with pre menopause.

While lean beef may be a good protein food to the average population, type 2 diabetics might choose to cut back on red meat and processed red meat sources and replace it with a heart-friendlier choice. Fresh seafood, rich in omega -3 fatty acids, would rank high on the list of a healthy eating plan.
