Certain Probiotics Are not as Harmless as Thought

Recently a medical publication stated that certain probiotics are not as harmless as thought. Researchers presented their findings at the American College of Chest Physicians 2022 Annual Meeting. 23,533 ICU admissions to a number of hospitals in Colorado over a 5-year period were the data base for this study. There was a clear relationship between taking probiotic powder and the fact that some of these gut bacteria make their way into the blood stream. This condition has the name of bacteremia. Although bacteremia is uncommon (only 0.37%), the mortality rate for those who developed probiotic-related bacteremia was 25.6%. This is about twofold greater than the 13.5% mortality rate of controls who did not take probiotics. The risk ratio was 2.23-fold higher for ICU patients who ingested probiotics versus those who did not. What killed the patients who took probiotics were the gut bacteria that entered into their blood stream.

Discussion of “certain probiotics are not as harmless as thought”

Physicians often recommend probiotics as tools to improve the gut bacterial flora. Unfortunately, there is a lack of research in this area. There is no hard evidence that probiotics are beneficial for irritable bowel syndrome or ulcerative colitis. There is also no hard evidence that a previously deranged bowel flora would transition into a healthy bowel flora. On the other hand, we also know that fermented vegetable products like kimchi or sauerkraut also have beneficial bacteria in them that can support your bowel flora. One of the problems is the concentration of probiotic supplements. They come in 80 billion, 100 billion and higher bacteria counts per capsule. It is possible that some of these bacteria find their way through cracks in the lining of the bowel into the blood stream.

Patients outside the ICU setting

ICU patients are vulnerable and often have immune deficiencies. It may be that in regular patients outside the ICU probiotics may not be that problematical. But nobody knows for sure as there are no studies available that support this. The practice of recommending probiotics over sauerkraut and kimchi is simply based on hearsay.

Risk assessment necessary

Once probiotic bacteria are in the blood, they can freely travel through the circulatory system into the rest of the body. This is how septicemia develops. This is a dangerous condition, which does not always respond to antibiotics. It is because of this why there is such a high mortality rate as I mentioned above.

As mentioned, there is a lack of good evidence for the beneficial effects of probiotics. However, there is a risk of bacteremia in ICU patients. This warrants a risk assessment whether or not we should supplement our food intake with probiotic supplements or not. Fermented vegetable products like kimchi or sauerkraut are not as highly concentrated as probiotic capsules. Nevertheless, they are useful supplements that you can mix into salads or use as a side dish to your main meal. Until the time that more evidence is available about probiotics it is best to not take probiotics. Replace it with kimchi and sauerkraut.

Fermented foods versus probiotics

Fermented foods like sauerkraut and kimchi can help the gut balance its bacteria. But there are other fermented foods that can help your gut: yoghurt and kefir, which is a fermented probiotic milk drink. Other fermented foods are tempeh, miso, kombucha and pickles. The good bacteria outnumber the bad bacteria when you consume fermented foods regularly. Kimchi does not only provide healthy gut digestion, but it also prevents the formation of toxins from unhealthy gut bacteria. These toxins can damage the kidneys. So, kimchi prevents kidney damage.

Sauerkraut and kimchi are fermented foods that have been consumed for hundreds of years. They provide nutrients, vitamins and minerals along with plenty of fiber and probiotic bacteria to support the gut. I consider kimchi and sauerkraut the better probiotic than probiotic pills, which likely are too concentrated.

Certain Probiotics Are not as Harmless as Thought

Certain Probiotics Are not as Harmless as Thought

Conclusion

Recently a publication reported about 23,533 ICU admissions to various hospitals in Colorado over a 5-year period. These patients took daily probiotics. There was a clear relationship between taking probiotic powder and the fact that some of these gut bacteria made their way into the blood stream. Unfortunately, there was a mortality risk of 25.6% for probiotic-related bacteremia. Controls not taking probiotics had a much lower mortality rate of 13.5%. The investigators concluded that a literature search failed to support beneficial effects of the probiotic powder. The evidence was rather weak and did not justify the risk of probiotic-bacteremia. In contrast, natural probiotics in the form of fermented foods like kimchi and sauerkraut have been around for centuries and are known to be safe. I see no reason why we should take a risk with probiotic pills when there are many alternative fermented foods.

Probiotics and a Phage Blend for Digestive Problems

In general, probiotics and a phage blend for digestive problems can help patients with irritable bowel syndrome (IBS). It is important to realize that about ¾ of Americans suffer from digestive problems. They develop symptoms of gas, bloating, diarrhea and stomach pains. To put it another way, about 1 in 7 Americans suffer from the condition, called chronic irritable bowel syndrome. That is to say, he underlying problem is an imbalance of gut bacteria where the bad ones outnumber the good ones. There are a number or reasons why bowel flora gets disrupted. We eat more processed foods, less fiber, and beef products from industry farms contain antibiotic residues. In feedlots for beef cattle antibiotics are fed to the animals as growth promoters. The residues in the meat kill the good bacteria in our guts and the bad ones proliferate. This causes digestive problems, but also weakens our immune system.

How probiotics work

Probiotics can restore our gut flora to a large extent. But some of the probiotic action gets lost in the stomach from the acidic milieu. A recent publication from a panel of gastroenterologists has not supported the wide use of probiotics. They came to the conclusion that probiotics have not shown enough benefit to a number of clinical conditions. The researchers mentioned Crohn’s disease, C. difficile infection, ulcerative colitis and irritable bowel syndrome (IBS) in particular of not responding to probiotics. But this may be because of inactivation of some of the power of the probiotics by stomach acid. In addition, by not using phages to potentiate the probiotic action probiotics may fail to permanently to improve the gut flora. I have previously discussed the importance of probiotics for the gut flora.

History and use of bacteriophages

Bacteriophages are now often just called phages. Dr. Frederick Twort, an Englishman detected phages in 1915 during World War I. Essentially a phage consists of either DNA or RNA and a protein envelope around this. Phages are very specific for certain bacterial strains. They attach to the bacteria and inject their own DNA or RNA into the bacteria. This stops the bacteria from multiplying, but makes the bacteria produce many more identical phages. Phages are useful to control the growth of problem bugs including antibiotic-resistant bacteria. However, the regulatory agencies were slow to approve phages despite a good safety record. Life Extension Magazine recently published a review article about this subject.

Phages helping to protect probiotic bacteria

Phages naturally play a role in keeping the gut flora stable. In this lengthy review, published in January 2020 phage actions are reviewed. It also mentions the connection between the gut flora and the immune system. The Life Extension Magazine article mentioned above describes experiments that show the action of phages. E. coli is the main bacterium in the large intestine. It is also the bacterium that can cause pneumonia, diarrhea and urinary tract infections.

Experiments with bacteria and phages in Petri dishes

According to the Life Extension Magazine article researchers did experiments with Bifidobacterium longum, one of the desirable gut bacteria. This was placed on a Petri dish along with E. coli bacteria. In a second Petri dish Bifidobacterium longum, E. coli and a phage mix were placed. After 5 hours there was hardly any growth of Bifidobacterium longum in the first petri dish, as it was crowded out by E. coli. The result in the second Petri dish was interesting: the Bifidobacterium longum colonies were 7000-times higher in number than in the other Petri dish without the phage mixture. The phages had selectively attacked the E. coli bacteria, which made room for the Bifidobacterium longum bacteria to multiply.

Animal experiments with bacteria and phages

The Life Extension Magazine review mentions animal experiments with phages next. One group of mice received B. longum and the disease-causing E. coli in their food. The other group had the same bacteria plus a mix of phages directed against E. coli. For the phage group the results within 24 hours were as follows.

  • The E. coli count in the small intestine was 10-fold lower, in the large intestine 100-fold lower and in the fecal matter 100-fold lower.
  • The phage group also had a 100-fold increase of the B. longum count in the small intestine. The large intestine also had a 100-fold increase of the B. longum count. And there was a 40-fold increase of B. longum in the fecal matter.

Control mice without the phage mix developed constipation and intestinal segments showed redness, swelling and leaks. In contrast, the phage mix group of mice showed no side effects and had improved digestive function.

Human studies using probiotics and a phage blend for digestive problems

Safety tests of phage therapy were next in 2005 involving 15 volunteers. There were no side effects using two different phage concentrations to diminish E. coli. Researchers had done other safety experiments in Russia and in Poland in the past. Patients with ulcerative colitis responded with improved symptoms and improved endoscopic findings to treatment with two probiotics. They received fermented milk products (Cultura) containing live lactobacilli (La-5) and bifidobacteria (Bb-12) for 4 weeks. There were 51 patients with ulcerative colitis and 10 patients with familial adenomatous polyposis. Abdominal cramps, Involuntary defecation, leakage and the need for napkins were significantly reduced in both groups. An endoscopic score of inflammation showed a significant decreased when the baseline exam was compared to the exam after the 4-week intervention.

Literature review about phages

Here is a thorough review in a publication dated 2011, which describes research from Poland and other countries describing the action of bacteriophages, now simply called phages. It lists many human experiments and shows that phages are safe to use in humans.

Irritable bowel syndrome

Irritable bowel syndrome (IBS) presents with a pathological intestinal function, which can be quite disabling. Another name for it is “spastic colon”, because many patients complain of significant bowel spasms. Some health providers still use this alternative term. This syndrome is more common among women and there is a theory that female hormones may have something to do with the pathophysiology of irritable bowel syndrome. Testosterone on the other hand may have a calming effect on the gastrointestinal tract.

Symptoms and treatment of IBS

Generally speaking, irritable bowel syndrome occurs first in the teens or early twenties, but then frequently tends to become chronic. The patient chiefly complains of abdominal bloating and distension. Bowel movements lead to a marked relief of pain. There is often mucous in the stools. After a bowel movement there is often a feeling that the rectum did not empty entirely, even though it did. Food intake or stress can bring on these symptoms and they always occur during the waking period. At nights most patients have no pain.

Among other measures taking probiotics alone or mixed with phages can normalize the bowel flora. In older men IBS symptoms may indicate a reduction in testosterone production. If the blood contains a low testosterone level, the physician may want to replace the missing testosterone with injections or bioidentical testosterone creams. This can improve IBS in older males.

A safe delivery system for probiotics and a phage blend for digestive problems

Life Extension has developed a dual capsule that brings the inner content safely through the stomach and protects the mix of probiotics and phages from stomach acid. The capsule only opens in the small intestine where it releases its content of probiotics and phages into the gut. This allows the good bacteria like B. longum to multiply and suppresses E. coli, which would otherwise interfere with the beneficial bacteria.

Probiotics and a Phage Blend for Digestive Problems

Probiotics and a Phage Blend for Digestive Problems

Conclusion

About ¾ of Americans suffer from digestive problems. Many have a disbalance of the gut flora. But it is not easy to replace poor gut flora with a healthy one. Recent research showed that a combination of 7 probiotic strains with a mix of 4 E. coli fighting phages can give tremendous relief from bloating, diarrhea and abdominal cramps to patients with irritable bowel syndrome (IBS). Life Extension has developed a special dual capsule that “sneaks” the capsule through the stomach. It will only open in the small intestine. This way the content of the inner capsule with the mix of probiotics/phages stays safe from the stomach acid. At the end many more beneficial bowel-bacteria are growing in the small and large intestine. This normalizes the symptoms of the patient and leads to better digestion of food. Probiotics and phages are the new players in the gut microbiome.

The Gut and Brain Connection

There is a lot of talk about the gut and brain connection. At the 23rd Annual World Congress on Anti-Aging Medicine (Dec. 11-13, 2015) in Las Vegas there were several lectures pointing out the importance of the gut flora for proper brain function. As a matter of fact, if you have the wrong gut flora, you can get a number of diseases like diabetes, fibromyalgia, rheumatoid arthritis, multiple sclerosis, muscular dystrophy, some cancers and even obesity. Martin P. Gallagher, MD, DC talked about this in his talk entitled “Gut on Fire, Brain on Fire!”

Function of the microbiome

The microbiome is the sum of all microbial organisms inhabiting the human body, which colonize mainly the colon, but also to a lesser degree the small intestine. Dr. Gallagher stated that the microbiome weighs only 7.1 oz., although in the past some have estimated its weight to be as high as 3 pounds. The purpose of the microbiome is to help form a gut/blood barrier. It forms a 30-micron thick layer in the GI tract, protects the intestinal lining and metabolizes food remnants, especially from carbohydrates. In addition, it also communicates with the immune system. There is a cross talk between the lining of the gut and the and the body’s immune system. The gut bacteria help the body to create stability; as a result the good bacteria also decrease intestinal permeability.

Leaky gut syndrome develops

When inflammation occurs in the gut, the thickness of the biofilm is less than 30 microns. Intestinal permeability increases and becomes “leaky gut syndrome”. This can be the cause of autoimmune diseases and possibly other diseases.

The enteric nervous system

The gut can produce as many neurotransmitters as the brain and spinal cord can synthesize. The enteric nervous system communicates with the brain through the vagal nerve. Serotonin is an important neurotransmitter that regulates motility of the gut. The control system of the gut can work on its own and override the concerns of the central nervous system.

Parkinson’s disease is a disorder of the enteric nervous system as well as the brain. With Alzheimer’s disease the characteristic brain lesions are also present in the enteric nervous system!

A mouse experiment showed the following. The Lactobacillus strain is  normally part of the microbiome of the gut.  Re-introduction of Lactobacillus into the gut flora resulted in healing certain parts of the brains of these animals, which researchers associate with anxiety and depression. But when the researchers severed the vagal nerve of these animals, none of these healing changes occurred.

The gut-brain-axis

For this reason the researchers suggested that the gut bacteria are able to communicate with the brain via the vagal nerve. Researchers have coined this connection the “gut-brain axis”. These protective gut bacteria have the ability to protect humans from gastric acidity, from bile acid toxicity, they adhere to the lining of the gut and they persist to reside within the gastrointestinal tract. Probiotics help the immune system to maintain the immunologic memory and to secrete antibodies, called immunoglobulins.

Two strains with benefit to humans are Lactobacillus rhamnosus GG and Saccharomyces boulardii. Probiotics often help against diarrhea. The natural food for gut bacteria in the colon comes from starches of chicory, asparagus, inulin and onions that are indigestible in the stomach and small intestine, but are fermented in the colon to provide food for the bacteria residing there.

Small Intestinal Bacterial Overgrowth (SIBO)

Overgrowth of the small intestine with bacteria that produce endotoxins appears to have significance in both animal models and human disease. Chlamydia species as well as Borrelia burgdorferi (Lyme) can produce toxins that cause hypersensitivity to pain in soft tissues in fibromyalgia and animal models of fibromyalgia. Moreover, SIBO – small intestinal bacterial overgrowth – in experimental animals caused the same hypersensitivity of the soft tissues and also leaky gut syndrome.

Risk factors for SIBO

What causes SIBO is too little stomach acid production, treatment with proton pump inhibitors (powerful anti acid medications) and antibiotics. To summarize, Dr.Gallagher said that SIBO also occurs in post-surgical patients, in patients with diabetes, is brought on by alcohol, nicotine, drugs and GMO foods.

Neurogenic inflammation

Normally the blood brain barrier keeps immune cells from the body out of the brain. Only glucose, proteins and lipids are allowed into the brain, but not lipophilic neurotoxins. In contrast, neurogenic triggers, when admitted to the brain, will compromise the function of the immune cells of the CNS, called microglia. In essence, this can result in memory loss, Alzheimer’s, dementia, seizures, migraines, Parkinson’s Disease, multiple sclerosis, cancer, weakness, numbness, etc.

What triggers inflammation?

Here is a long list of different items that cause inflammation: aging, hormone deficiencies, obesity, diabetes mellitus, cardiovascular disease, fungal infection, the Standard American diet (SAD), pain, trauma and mechanical stress, heavy metals, food allergies, toxins, gut dysbiosis, small intestinal bacterial overgrowth, mal-digestion/absorption, prescription drugs, over-the-counter drugs, recreational drugs and alcohol, lack of exercise and lack of sleep.

Neurotoxic insults start the chain of reactions  like heavy metals, nutritional deficiencies, viruses/fungus/bacteria, inflammatory diet, MSG, solvents, pesticides, herbicides, etc.. One or more of these factors destabilize the tight junctions of the blood brain barrier, which leads to neurogenic inflammation.

Result of neurogenic inflammation

The result is Parkinson’s disease, MS, dementia, chronic pain, behavioral and personality changes, Alzheimer’s disease, ALS and Lyme disease. What seems to be happening a lot is that there is overgrowth of abnormal bacteria in the small bowel, which produce toxins. These in turn lead to leaky gut syndrome, which allows neurogenic triggers to attack the blood brain barrier. It seems like from here it is a short step to neurotoxic insults of the brain overstimulating the microglia, which will produce the diseases listed above.

Healing of brain inflammation

First of all, treatment starts with the Mediterranean diet, which has been shown to have anti-inflammatory properties. Second, people who are gluten sensitive need to eliminate gluten entirely from their food. Third, casein sensitive people need to eliminate dairy products. Furthermore, a triple strength, molecularly distilled fish oil product is taken as a supplement every day with 4 grams or more of DHA/EPA. This helps the anti-inflammatory response.

Glutathione

One of the most powerful antioxidants and anti-inflammatories is intravenous glutathione. This is given as intravenous chelation therapy, which removes heavy metals. Other chelation agents such as EDTA intravenously may be given alternatively. Dr.Gallagher said that glutathione serves as primary cellular defense against free radicals, is a powerful antioxidant and serves as detoxifying agent against xenobiotics. Xenobiotics are remnants of artificial fertilizers, pesticides and pollutants that are contained in crops we eat.

Dr. Gallagher gives 600mg of glutathione twice per day intravenously for 30 days. Uniquely, in Parkinson’s disease patients whose mid brain is often poisoned by mercury this leads to 42% decline of disabilities and the effect lasts for 2 to 4 months after this treatment has been stopped. Coupled with this the treatment also protects telomeres, the caps on the ends of cellular DNA as well as mitochondrial DNA. In addition, glutathione is protective of neurons and nerves.

Curcumin

This common Indian spice, found in turmeric is a potent anti-inflammatory. It is a safe natural agent and has also anti-viral and anti-tumor activities. It binds to the vitamin D receptor and works synergistically together with vitamin D3. Solid lipid curcumin particle technology makes curcumin 65-fold more bioavailable; free curcumin is allowed to pass the blood brain barrier. Lower doses achieve the same effect than regular curcumin.

According to a publication using lipidated curcumin the following observations were made: improved vascular function; equally important, inflammatory markers reduced by 14%; in like manner, triglycerides lowered by 14%; by the same token, oxidative stress reduced; not to mention, catalase increased and finally total antioxidant status improved. Here is another paper about lipidated curcumin.

Omega-3 fatty acids

Omega-3 fatty acids are anti-inflammatory by countering the arachidonic acid pathway that leads to inflammation. Physicians recommend it as triple strength, molecularly distilled fish oil. DHA/EPA are the active ingredients. Chronic inflammation requires 2 to 12 grams daily; irritable bowel syndrome 6 to 12 grams daily; depression, anxiety and insomnia require 2 to 4 grams per day; autoimmune disease, back pain and degenerative joint disease 4 to 12 grams per day.

Gut/brain dysbiosis

For gut/brain dysbiosis Dr. Gallagher recommended to start with a 10-day fruit/vegetable detox program. Milk thistle, glutathione and pancreatic enzymes in combination lead to improvement. Lipidated curcumin is also useful. The physician also gives glutamine, prebiotics and probiotics for gut support. He also tells the patient to take molecularly distilled fish oil (DHA/EPA) and vitamin D3 as anti-inflammatories. Doctors also administer oral and intravenous glutathione to detoxify. Many doctors use natural as a combination of glutathione, oregano, olive leaf and silver salts.

The Gut and Brain Connection

The Gut and Brain Connection

Conclusion

Inflammation can start in the gut, lead to leaky gut syndrome and break down the blood/brain barrier. The end result is that inflammation develops in the brain and Alzheimer’s disease and dementia can occur. The sooner the physician starts with treatment, the faster the recovery is. When the patient has reached the end stage, it is difficult to turn the inflammatory process around. Fortunately there are effective ways to get the inflammation under control with intravenous glutathione in the beginning and subsequent treatment with lipidated curcumin, omega-3 fatty acid and vitamin D3. A permanent switch to a Mediterranean diet is important as well to keep inflammation under control.

Lifestyle and nutrition choices are important for prevention

A few years back this mainstream medicine considered this type of approach as “quackery”; now it is the latest information from research into the brain/gut connection. The right lifestyle and nutrition choices can do a lot on a preventative basis. Once disease has taken root, treatment may still be possible, but once it is at a later stage a full cure is unlikely.

Probiotics Are Important For Your Health

We need to be aware that probiotics are important for your health. Growing up in Germany after World War II I remember that occasionally there were interesting newspaper headings. It  showed an older person in the nineties when the average life expectancy was in the late 60’s. The reporter asked, “What did you do to turn that old?” The answer was that the person always ate a lot of yogurt.

This did not sink into mainstream medicine at that time and people did not really believe this statement. How could eating yogurt make a person live longer?

Fast forward to 2014. You read about probiotics in magazines, on the Internet, and even TV commercials expose you to it.

In the Wikipedia it is accepted that yogurt can help seniors who have a lower bifidus bacteria population in their colon to rebalance their gut flora, which will prevent colon cancer. It also describes that yogurt can help yeast infections in women.

In the meantime probiotics have been developed and concentrations like 20 to 80 billion bacteria per capsule with a mix of Lactobacillus and Bifidobacterium species are available in the health food store for prevention.

The medical profession has studied the effects of higher potency probiotics and came to the conclusion that probiotics have indeed effects on the body far beyond the gut.

Here are a few highlights.

Bowel disease improves

In cases of bacterial or viral diarrhea the frequency of bowel movements and the intensity of bowel cramps gets helped within a few days, and recovery from the diarrhea is much faster with probiotic than without. Patient with irritable bowel syndrome and ulcerative colitis are helped with probiotics. Probiotics help both constipation and diarrhea in otherwise healthy people as well.

Immune system booster

The small bowel contains clusters of immune cells within the bowel wall. Together they are a formidable immune organ in the gut, which connects to the blood and the rest of the immune system throughout the body (lymph glands, spleen, bone marrow). Specifically it has been proven in humans that macrophages, natural killer (NK) cells and cytotoxic T-lymphocytes, which are the working horses of the immune system, are all stimulated by probiotics.

Less respiratory infections

School children who were given 1 capsule of probiotics twice per day for 3 months and flu symptoms and absenteeism were observed due to colds and flus. When they did get a viral infection, the illness had a shorter course, resulting in much less school absenteeism over the course of the trial when compared to a placebo group. It seems that a healthy gut flora stimulates the immune system to work at its best.

Cancer prevention

To a certain degree cancer can be prevented by probiotics and other nutritional factors. Breast cancer is one of the cancers where probiotics have been shown to be effective in reducing disease.

Apparently the probiotic bacteria bind to the cancer causing factors (carcinogens) that some of the bad gut bacteria produce. Probiotics also suppress other bacteria that convert pro-carcinogens into carcinogens. This is not all: the probiotics also interfere with enzymes involved in the production of carcinogens in the gut. This stimulates the gut immune cells to produce cytokines that are needed in the battle against early cancer. Probiotics play a role in multiple processes that help the body to fight cancer, not only in the gut, but also in the rest of the body!

Helps diabetes get better

How can gut bacteria help diabetes, which is an endocrinological disease? Both human and animal studies have shown that insulin resistance is improved by probiotics. In a 6-week study both blood sugar levels and hemoglobin A1C values (that measure long-term control of diabetes) dropped significantly by eating 300 grams of yoghurt per day when compared to a control group who did not.

Obesity

Probiotics given to mothers at least one month prior to birth and at least up to 6 months after birth prevented excessive weight gain in both the mothers and their children. In addition, probiotics can suppress a lot of the inflammatory substances in obesity.

Probiotics reduce cardiovascular risk

Several studies have shown that probiotics lower LDL cholesterol, total cholesterol and inflammatory markers in the blood stream resulting in lower risk for hardening of the arteries.

One should not look at probiotics as a single factor for prevention of heart attacks and strokes. Combine probiotics with exercise and a low refined carbohydrate diet. High sugar and starch diets lead to absorption of sugar in the stomach and small intestine. This results in a lack of nutrients to support the gut flora. Combine probiotics with vegetables and lettuce. Then you have the proper mix of fiber, minerals and other nutrients to sustain balanced bacteria in the bowels. This prevents heart attacks and strokes and keeps inflammatory markers down. I have blogged about this before and stated that the combination of organic food (to avoid antibiotic residues in our diet), fruit and vegetables combined with probiotics will protect you from heart attacks and strokes.

Probiotics Important For Your Health

Probiotics Are Important For Your Health

Conclusion

Maybe the newspaper articles in Germany after the Second World War were right. There is something in yogurt (Lactobacillus and Bifidobacterium species) that can make you live longer. The explanation seems simple: add probiotics to your diet.  You will have a better immune system and get less respiratory infections. But you also prevent heart attacks, strokes and prevent obesity and cancer. All of this in combination will lead to healthier lives, and more people will live to tell about it.

Fighting Back Against The Flu

Every year there is concern about the upcoming flu season. Mostly the discussion centers on the composition of the latest flu bugs and what type of strains would be included in the latest vaccine recommended. The first flu case of the season has just been reported in a child. Here I am going to review what you can do to minimize your probability of getting the flu, or if you get it, how to minimize the severity of the illness.

The immune system

We know for some time that the antibody-mediated immune system is what helps overcome flus. The body’s immune system produces antibodies against the flu via T-helper cells that recognize the glycoprotein (hemagglutinin) of the flu virus and pass a signal on to B cells (bone marrow derived lymphocytes), which in turn are turned on to produce a lot of antibodies (Ref.1). These protect you from future flus of this type. If you have pre-existing antibodies that fit the bug in circulation you are OK ,and you will usually not get the disease.

The factors that protect you from the flu

However, there are many other factors that support your immune system. I will discuss the most important factors in more detail here.

1. We do know that vitamin D3 strengthens the immune system. I would recommend 1000 to 2000 IU per day in the wintertime, but up to 4000 IU or 5000 IU per day during an active epidemic would be reasonable. There is less flu when people are taking Vitamin D3 supplements.

Influenza A was reduced in school children supplemented with 1200IU of vitamin D3. This study recommended higher doses of 2000 to 7000 IU of vitamin D3 per day; but it also stated that as a precaution serum vitamin D levels should be monitored (technically it is serum 25-hydroxy-vitamin D levels that are measured) to avoid vitamin D toxicity. Normal levels are between 40-70 nanograms per ml. Toxic levels are above 100 nanograms per ml. Your family doctor can order a serum 25-hydroxy-vitamin D level for you.

2. Eating fruit and vegetables is important for maintaining a healthy immune system. In a randomized study from Belfast, UK elderly volunteers (82 of them, aged 65 to 85) were assigned to either eat 2 portions or 5 portions of fruit and vegetables per day over 16 weeks. At 12 weeks into the trial both groups received a Pneumovax II vaccination, and the antibody response was measured at the end of the 16th week of the study.  There was a significant increase in antibody binding capacity to pneumococcal capsular polysaccharide in the 5 portion fruit and vegetable group compared to the 2 portion group that had no such increase. The authors concluded that there is a measurable improvement of the immune system when an older population increases their fruit and vegetable intake.

3. Avoid stress, because stress has been shown to weaken the immune system. This review shows that the immune system is weakened by the stress response via the elevated corticosteroid hormones (the stress hormone ACTH stimulates cortisol release from the adrenal glands). The stress of social isolation is also contributing to the weakening of the immune system in older people.

4. Exercise moderately and your immune system will get strengthened. Over exercising should be avoided as too much cortisol is released from your adrenal glands, which is toxic to lymphocytes thus weakening your immune system.

5.  Socializing is good for you as studies have shown that you live 2 ½ years longer. This study here is from Connecticut, but other studies confirmed this as well.

6. Make love. The endorphins that are released in the process stimulate the immune system.

7. Take probiotics, because they help your gut flora to stay normal. A normal gut flora promotes a stronger immune system as the Peyer’s patches (clumps of immune cells) in the gut wall are intimately linked to the immune system. In this way probiotics indirectly support your immune system.

8. Avoid smoking.  Smokers have more upper and lower respiratory tract infections than non-smokers. Here is information that explains this as well.

9. Get enough sleep. The circadian rhythm of your hormones ensures that your hormones function at their optimal level. Melatonin from the pineal gland is important in triggering the circadian rhythm, but melatonin itself supports the immune system as well. Your adrenal glands need resetting overnight so that cortisol is secreted according to your stress level, not too much and not too little. Overstimulation from performance sports, grief reactions, car accidents, injuries etc. lead to a surplus of cortisol and weakening of the immune system.

10. Take your flu shot (but without thimerosal) every year, but take it as a single shot (without thimerosal as a preservative). This CDC link explains that single shot flu vaccines are available without thimerosal. I recommend this type of flu vaccine. The central nervous system is extremely sensitive to nanograms of mercury, and it is for this reason that I would not buy into the argument of the CDC that one should not be concerned about safety of thimerosal. The newest for this flu season is the quadrivalent (or four-strain) flu vaccine, which is now available in pharmacies throughout the US.

11. Vitamins and supplements support your immune system, particularly vitamin D3. DHEA, which is available over the counter in the US stimulates antibody production when the flu vaccine is given, particularly in the elderly, in other words DHEA strengthens the immune system Vitamin C is known to support the immune system and is rapidly depleted in those who suffer from any viral infection. There are other nutrients that are useful to stimulate your immune system.

12. Consider herbs: Echinacea, Siberian ginseng, Asian and American ginseng, astragalus, garlic, and shiitake, reishi (also called “lingzhi mushroom”) and maitake mushrooms have all been shown to stimulate the immune system with negligible side effects.

13. Wash your hands, particularly when there is a flu going around. Door knobs for instance are known to keep live viruses for 2 to 8 hours, so washing your hands will reduce the amount of virus you are exposed to.

Conclusion

There is no single solution to prevent the flu, but we can all minimize our exposure to the virus and strengthen our immune system. Although it is wise to get a yearly flu shot to boost your immune system (without thimerosal as a preservative) just before the epidemics come around, this alone is not as good as combining the non-specific factors mentioned here with it. Particularly vitamin D3 (2000 IU to 4000 IU per day) and the old stand-by vitamin C (1000 mg to 2000 mg daily) will stimulate your immune system. Spice up your dinners with mushrooms that stimulate your immune system (maitake, shiitake, reishi mushrooms). Go to bed early enough to allow your circadian hormone rhythms to be reset overnight as you sleep. This will stimulate your immune system (from melatonin and DHEA of your adrenal glands).

Changes Of Gut Bacteria Can Cause Heart Attacks

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!

Probiotics Help Gut Against Stress

In times of stress our bodies react: the heart will beat faster, palms will feel sweaty, and a difficult situation may manifest itself in other reactions of the body. In every day’s terms we speak about something “being a pain in the neck”, or the fear of an exam showing up as “butterflies in the stomach”.
Dr. Mary Perdue of the Intestinal Diseases Research Program at Mc Master University in Hamilton, Ontario went a step further. The fact that mental stress can bring physiologic changes in the lining of the intestine has been known for some time. As a result the epithelium (the lining) is more vulnerable to the attack of pathogenic bacteria. The researchers put a solution of lactobacillus to the test, to see whether these gut-friendly bacilli could offer some help. Stressed rats that received the treatment with lactobacillus showed a remarkable degree of protection. The stressed and treated animals were almost as resistant to intestinal pathogens as animals that had not been stressed at all. Contrary to that the non-stressed animals did not show much evidence of bacterial adhesion or penetration: they were more resistant to the attack of bacteria to their guts.
Dr. Perdue explains that it may be difficult to extrapolate from the rat model to the human model. Yet it is clear that humans who are stressed can develop intestinal dysfunction over time, or gastrointestinal symptoms can be exacerbated by stress.
In the meantime probiotics are recommended by many doctors and nutritionists to help restore the gut’s natural flora. New guidelines from Yale Medical School recommend them for diarrhea in children and adults and in diarrhea, which comes as a result of treatment with antibiotics.

More research is needed, but existing data suggest that probiotics can help manage lactose intolerance, prevent infections, and reduce inflammation. It can lower cholesterol and lower blood pressure and may help with prevention of colon cancer.
