The role of probiotics

Probiotics are beneficial microorganisms that are oral , intestinal and vaginal flora. Their presence can counter the proliferation of harmful microorganisms that can cause diseases. Probiotics also help to digest food. In a healthy body, the digestive tract is colonized by approximately 100,000 billion bacteria belonging to 400 different species. 30 to 40 species of these bacteria account for 99 % of the flora which forms a stable ecosystem essential for maintaining good health. Any event that disrupts the balance of intestinal flora can cause diseases.


Probiotics act by three main mechanisms. The first is to modulate the activity of the intestinal immune system. Probiotics enhance immunity when it is low, such as during the development of children immune system and the elderly . They also decrease the overactivity of the immune system, especially in cases of allergies and inflammatory bowel disease. Second , probiotics enhance the barrier function of the intestinal mucosa, for example by increasing the production of mucus or antibodies. Finally , probiotics have direct antimicrobial effects, taking the place of pathogenic bacteria (due to fermentation and putrefaction ) and preventing their adhesion to the intestinal walls.



Our frendly instestinal flora


• they provide in the colon, digest food not yet processed in the small intestine ;

• they complete the full breakdown of food and waste disposal ( vital step which we would get intoxicated fast) ;

• they degrade some of the cholesterol , reducing its rate ;

• they improve protein digestibility ;

• They increase the acidity of the intestine, which prevents the growth of many bacteria ;

• they produce enzymes for the realization of many metabolic reactions ;

• it facilitates the assimilation of vitamins and minerals;

• they synthesize vitamins B and K;

• they contribute to the renewal of intestinal cells ;

• They are used to activate the natural phytoestrogens in treatment of menopause ( failures are often due to a disturbed flora ) ;

• They protect the body from pathogenic strains by preventing them from attaching to the mucosa (the barrier effect ) ;

• they enhance the immune and all mucosal system.


A good flora helps prevent colon cancer, the most common and one of the murderers. Having a good flora reduces the risk of various deseases. The cell wall of lactic acid bacteria absorbs carcinogenic substances (produced during cooking at high temperature ) the same active wall wich white blood cells swallow cancer cells.


Lactic acid bacteria are among the main probiotics. Generic name comes from the fact that they produce lactic acid. They include, lactobacilli ( bacteria of Lactobacillus ) , bifidobacteria ( Bifidobacterium bacteria ) and some streptococci ( Streptococcus bacteria ). These are bacteria of this type generally used in the production of yogurt ( Lactobacillus bulgaricus , Streptococcus thermophilus ), sauerkraut , lactofermented vegetables.


Active beer yeast (called Bjast rich in B12 ) is also a probiotic. It consists of fungi, usually of the species Saccharomyces cerevisiae. These micro-organisms that are not pathogenic, digest sugar and starch grains, creating an environment rich in protein and vitamins, especially B vitamins ( they are one of the most important natural sources thiamine, a B vitamin essential for the metabolism of carbohydrates and fats ).
