[Importance of correcting the protein, fat and vitamin content of the diets for the work capacity of young people during exams].

Study of the working capacity of young people fed various rations during examinations has shown that the examinations considerably affected a number of psychophysiologic characteristics. Addition of olive and particularly sunflower oil (20 g daily) into the rations promoted neuro-reflex activation, that manifested in reduced time of sensory motor reactions; attention function also improved. Intake of vitamin B2 (0.01 g daily) and particularly undevite (3 dragees daily) contributed to improvement of attention function, as well as of working capacity. High milk protein balanced rations helped to reduce the unfavourable effects of examination stress on the body. Students of this group have shown the working capacity and attention practically the same as during routine studies, both being much higher than in students on traditional nutrition. Intake of undevite contributed to a further improvement of the psychophysiological parameters.
