Bifidus, Lactobacillus, Streptococcus? are all live bacteria probiotic component. These microorganisms are incorporated into dairy products and other dietary supplements.Probiotics are expected to maintain and strengthen the intestinal flora. What exactly?
What are probiotics?
Probiotics are live microorganisms which, when ingested, have beneficial effects on health and particularly on the gut flora. They are typically added to foods, mainly dairy products, or contained in food supplements. The problem is that the composition of intestinal flora and functioning of intestinal cells are so complex that it is difficult to provide compelling evidence.
Intestinal mucosa and bacterial flora: incredibly complex
Our intestinal mucosa is the largest of the whole organism. The proof consists of multiple folds (intestines), the length of the small intestine is 6 meters long and has 10 to 100 times the number of body cells. Our intestines are also colonized by many families of bacteria: each of us harbors a middle of bacterial species, including 80% of its own. Thus, the intestines are also the most important for their function. Here, amid the bacterial flora that food is digested (fermentation process), as vitamins are manufactured, as the pathogens are eliminated, that toxic chemicals are neutralized.
Probiotics in yogurts and supplements
We understand better with such explanations why the effects of probiotics are so difficult to demonstrate. For most, they are now from tests on cells or animals, whose results are then extrapolated to humans. Yet they are very important: improved intestinal transit, strengthening the immune intestinal essential to prevent intestinal infections, and prevention of diarrhée.Les only evidence introduced in humans relate incorporated probiotics in dairy products (yogurt: Actimel, Activia, LC1; infant formulas: Nidal) and two dietary supplements (Bion 3 and Lactibiane). Finally, note that probiotics provided by diet or supplements can not implant in the intestine and develop there in an autonomous way.That is why they must be ingested daily as a treatment.
