[Dietary prevention of certain changes in the human body in the presence of neuro-emotional stress].

Simulated stress conditions (rise to a simulated altitude of 8000 m, anticipation of an exposure to acceleration, mental work to be done under the conditions of time deficiency, "success" or "failure") brought about changes in the protein, carbohydrate, vitamin metabolism, heart rate, adrenal function, and peripheral blood. Nutrient ingredients (vitamins, glucose, minerals, phosphatid concentrate) added to the diet before and during stressful exposures were shown to correct the parameters studied.
