[Supply of vitamins C and B1 of students attending a rural professional-technical school in the middle Volga region].
Actual nutrition and providing with vitamins C and B1 was studied in boys aged 16-17 years--students of a rural trade school in the town of Volsk, the Saratov region. Although the fuel value of their ration was sufficient (2900-3000 Kcal), the content of animal proteins comprised at an average 42 g/day. The content of ascorbic acid in the ration (evaluated by the analytical method) comprised 48% (in autumn) and 17% (in spring) of the recommended standard; the level of vitamin B1 did not differ depending on the season on the year. In spring, vitamin C and B1 deficiency detected in the students was proved by their low excretion with urine, as well as by a lowered level of vitamin C and low activity of B1-dependent transketolase enzyme in the blood of the subjects studied.
