Nutrient intakes of female adolescents from eight southern states.J Am Diet Assoc. 1984 Dec; 84(12):1453-60.JA
Nutrient intakes were calculated from two 24-hour recalls for 1,247 adolescent black and white girls. Whites consumed more vitamins E, C, and B-12, niacin, folacin, calcium, phosphorus, magnesium, and zinc and had higher intakes per 1,000 kcal of those nutrients, protein, vitamin D, and iron than blacks. Intakes of calcium (whites) and magnesium (both races) decreased with age. Urban girls consumed more energy and magnesium than rural ones. Folacin intake increased with income. Folacin intakes were most frequently below 67% RDAs, followed by intakes of iodine, vitamin D, iron, calcium, vitamin B-6, zinc, magnesium, and vitamin A. The majority of diets met or exceeded RDAs for protein, vitamins E, C, and B-12, riboflavin, and thiamin. Intakes are reported for most nutrients for which safe ranges have been set.
