The importance of the microflora of the human digestive system. List of functions of microflora, without which human health is impossible:
1. Stimulation of immune activity;
2. Antagonistic action against foreign bacteria due to synthesis colicins, alcohols, hydrogen peroxide, lactic and other acids, fatty acids;
3. Increased assimilation of Fe, Ca, vitamin D (due to the creation of an acidic environment);
4. The destruction of the excess of digestive secretions - enterokinase and phosphatase;
5. Participation in metabolism:
- convert choline into tetramethylamine; bilirubin - in urobilin;
- decompose proteins to indole, skatole and phenol - resulting in improved
peristalsis;
- synthesize 9 vitamins - pyridoxine, riboflavin, nicotinic and
pantothenic acid, cyanocobalamin (B12), vitamin K. Biotin, folic acid
acid and thiamine provide the body with almost 100%;
- synthesize essential amino acids and vitamins, promote education
leukocytes;
cause activation of thyroid function (affect gas exchange) and
increased renewal of cells of the intestinal mucosa;
- fix nitrogen of air and promote protein synthesis;
- synthesize or convert cholesterol into components (sterbilin,
coprosterol, desoxycholic and lithocholic acids), depending on the need
organism;
- affect the absorption of water from the intestine - increase absorption.
(Data from the Institute of Ecology and Medicine, Kiev, Ukraine).
*Weight of microflora is 2.5 - 3 kg*.

***"Formula of nutrition: food should fully meet the needs of the intestinal microflora."***
