Recommended Dietary Allowances (RDAs) are recognized as the most authoritative source of information on nutrient levels for healthy people. This new series of references extends the scope and application of previous nutrient guidelines. For each nutrient the book presents what is known about how the nutrient functions in the human body, what the best method is to determine its requirements, which factors (caffeine or exercise, for example) may affect how it works, and how the nutrient may be related to chronic disease. This volume presents information about thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. Based on analysis of nutrient metabolism in humans and data on intakes in the U.S. population, the Standing Committee on Dietary Reference Intakes recommends intakes for each age group--from the first days of life through childhood, sexual maturity, midlife, and the later years. This volume also makes recommendations for pregnant and lactating women and identifies when intake of a nutrient may be too much.
