This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient.
Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also:
- Reviews selected components of food that may influence the bioavailability of these compounds.
- Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role.
- Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups.
- Identifies research needed to improve knowledge of the role of these micronutrients in human health.
This book will be important to professionals in nutrition research and education.
"These volumes, including the latest on trace elements and vitamins A and K, provide high-quality reviews of the literature on each nutrient. ...Many nutrition educators will probably find this information surprising and at first might think that the details provided are not useful to them as they work with consumers and other health care workers. However, the details of the process will help nutrition educators understand better the evolutionary nature of diet standards."
