The purpose of this study was to rationale for approaches of maintaining the digestive and transport functions of the small intestine in sanogenical limits under stress  using nutritive factors based on the own experimental data. The proved methods of maintaining the digestive and transport functions of the small intestine in sanogenical limits under stress conditions using nutritive factor are as follows: 1. to reduce the diet of the relative amount of the active transported monosaccharide’s and to increase other monosaccharide’s through passive transport; 2. to increase the amount in the diet of nutrients  that contribute to optimizing the level of free calcium in the intestinal cell; 3. to increase the amount in the diet of nutrients necessary for the synthesis of serotonin; 4. to increase the consumption of antioxidants; 5. regular use of mineral water cures sulfatechloride-hydrocarbonate sodium-potassium-magnesium.
