THE INFLUENCE OF NUTRITION ON IMMUNE RESPONSE OF PEOPLE IN THE NORTH

Abstract

In conditions of ecological trouble, changed quality of food, poor diet, one of the urgent problems of our time is the problem of digestive process disorders. The digestive system contributes significantly to formation and maintenance of functional activity of the immune system; the most significant amount of immune competent cells is concentrated in the intestine, which plays an important role in generation of the entire immune system. The paper has presented the results of a study of influence of diet types on the immune status of the inhabitants of the North. It has been found that prevalence of seafood in the diet stimulated motor activity of the gastrointestinal tract and the mucous barrier protective properties by increasing content of IgA, gastrin-17, SP neurotransmitter in blood. Predominant consumption of seafood influences differentiation and proliferation of lymphocytes with formation of T-helpers 2 type and stimulates antibody formation. This causes activation of the reaginic mechanism and, as a result, enhancement of the gastrointestinal tract mucous barrier function, the increased level of polysaccharides of the mucin type in the epithelial cells. It has been detected that the level of content of the carrier IgG to food antigens depended on frequency of products' use in diets.
