Folate, vitamin B6 and vitamin B12 in adolescence: serum concentrations, prevalence of inadequate intakes and sources in food

Abstract

The prevalence rates of inadequate folate, vitamin B6 and vitamin B12 intakes were low, which is possibly the result of improved access to and availability of foods that are dietary sources of these vitamins. Beans, which are a part of the traditional Brazilian diet, remain one of the primary food items that contribute to folate intake, even after mandatory fortification with folic acid in Brazil.
