Probiotics and immune system

I am still amazed at the fact that in England, most doctors still are oblivious to recommend probiotics and multivitamins after they have prescribed antibiotics or after diarrhoea infection of any kind. Doctors in Italy suggested multivitamins to children and adult 30 years ago and at least for the past 10 to 15 years they suggest probiotics to all children and adults after a rotavirus or any other intestinal. It is always amazing at the huge difference of suggestions. I am sure that quite few doctors do know about the benefit of doing so, but I wander if they do not suggest that because they assume that people cannot afford to buy them. I am sure that any person that can or cannot afford to buy the probiotics would want the option of knowing what is best for them regardless of the cost. Here I summarized some of the benefit of taking probiotics with or without infections.

Microbacteria are part of our gut ecology and depend on what type of bacteria is more prevalent which can help the immune system or cause problems with it. The lumen of the intestinal tract (the small intestine) has got the most bacteria followed by the colon. The stomach does not have many friendly bacteria as they would be killed by the stomach acid. Most friendly bacteria that are found in the intestine are the Bifido species and the Lactobacillus species. The colonization of the intestinal tract starts from birth and it depends on the health of the baby and the milk given on how much will stay and protect the intestinal tract and therefore help the immune system (some formula now include probiotics and the milk of the mother especially the first few days of life will have colostrum which protect and repair the intestinal tract. Things that would destroy the friendly bacteria includes: antibiotics, diarrhoea, viral diarrhoea, allergies reactions, alcoholic drinks and some medication. Consuming a live yogurt or actimel type yogurt is not enough to repopulate the intestinal tract with the billions of good bacteria that it needs when the intestinal tract ecology is not well balanced.

Several studies have shown the benefit of the probiotics. Some of these benefits are protecting the intestinal tract in the children diarrhoea infection by the rotavirus, some protection after a vaccination in adult volunteers, protection against recurrent inflammatory intestinal disorders (there are still many studies on their way regarding the benefit for Chron’s disease, irritable bowel syndrome and ulcerative colitis). Some reduction of allergies, the IgE count goes down in elderly subject with nasal allergies, reduction in milk hypersensitive infants and adults, reduction in tumour recurrence in adult bladder and many others. The most used strains of probiotics used in the research are the Lactobacillus acidophilus, the Lactobacillus rhamnosus GG, and the Lactobacillus casei Shirota, La1 lactobacillus johnsonii and Lactobacillus brevi. The Bifido species are found in the colon section of the intestine in the most used are Bifidobacterium bifidum Bb12, Bifidobacterium lactis HN019 and Bifidobacterium brevisYIT4064.

The best way of getting the proper benefits of the friendly bacteria after antibiotics or for helping the elimination process is to buy one that has got all the different strains (for children there are appropriate ones either in powder of liquid). For adults the combination should be a total of billions of them to be most effective. If there are any intestinal settling when you first take the probiotics, the dosage should be reduced until the intestinal tract is settled. The good probiotics will cost a bit more than the common ones but they are worth it and YOU are worth it….
