title: Vitamin B-12 and folate intakes and plasma levels of black adolescent females.
abstract: The vitamin B-12 and folate intakes and plasma levels of 39 healthy black female adolescents were evaluated. Estimated dietary folate intakes of 97% of the subjects were less than 2/3 of the RDA, and 74% had plasma folate levels indicative of marginal (3.0 to 5.9 ng/ml [less than 6 nmol/:]), nmol/L]), and 3%, deficient (below 3.0 ng/ml [less than 6 nmol/L]) folate status. Thirteen percent of the subjects had estimated dietary intakes below 2/3 of the RDA for vitamin B-12; all subjects had plasma levels indicative of adequate vitamin B-12 status.
