THE EFFECT OF ULTRAVIOLET IRRADIATION ON THE MINERAL AND NITROGEN METABOLISM OF ADOLESCENTS

Abstract

The feeding of students in a trade school is conducted in accordance with the existing norms, but the content of nutritive substances in the students' rations, such as proteins, fats (especially animal) and calcium from the mineral substances, is lower than the physiological norms. A prophylactic irradiation of the youths with ultraviolet rays significantly increase the capability of the organism to utilize the mineral substances and proteins of the food. The retention of calcium in the organism after the ultraviolet irradiation was raised from 34.9 to 62.4%, phosphorus - from 22.2 to 41.9% and nitrogen - from 26.2 to 32.1%. The results which were received enable the raising of a question concerning the increase in products of animal origin and vegetables in the nutrition of students.
