Probiotics Are Important For Your Health

By | Abdominal Pain, Cancer, Diabetes, Gastrointestinal Disease, Heart Disease, Infectious Disease, Nutrition, Obesity, Stroke

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

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.

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.

Changes Of Gut Bacteria Can Cause Heart Attacks

Changes Of Gut Bacteria Can Cause Heart Attacks

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

By | Cancer, Gastrointestinal Disease, Health, Heart Disease, High Blood Pressure, Nutrition

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.
