title: [Nutritional value of daily diets prepared in several regions of the country. Part V. Value of group b vitamins].
abstract: Studies of the content of group B vitamins: thiamin, riboflavin, niacin and vitamin b6 in daily diets of manual and mental workers with medium income were carried on. The diets were prepared for five regions of the country (Warszawa, Lublin, Olsztyn, Poznań, Wrocław) under laboratory conditions. These diets contained respectively: thiamin 1.17 and 1.11 mg, riboflavin 1.48 and 1.55 mg; niacin 11.3 and 10.2 mg and vitamin B6 1.50 and 1.21 mg per day. According to the studies the realization of daily requirements by these diets for thiamin were met 82 and 98%, for niacin 62 and 65%, and for vitamin B6 79 and 64%. The comparison of the presently studied diets with the ones from 1973, 1980 and 1981 showed that the content of niacin and vitamin B6 intakes systematically decrease. There were no considerable differences in the contents of group B vitamins between diets prepared in all five regions of Poland.
