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.

This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.

Abstract: A report presents findings on the money value, quantity, and nutritive value of food used at home and costs for food away from home for Puerto Rican households in 1977. Data on the nutrient return per dollar's worth of food and on nutrient density (per 1,000 calories) are included. The nutrient content of food used at home was obtained both from information collected on kinds and quantities of food used by households during a 7 day period, and from USDA composition tables. Nutrient levels of food used by households are expressed as percentages of the 1974 RDA's; findings are grouped by urbanization, income, and household size. (rkm).

Abstract: A survey of 4400 low-income households eligible for food stamps was conducted in 1977-78 to study certain population subgroups; dietary intake levels were evaluated and the impact of food programs on nutritional status was assessed. Data were obtained on kind, form, quantity, and cost of foods used at home for a 7-day period. Demographic information included household size, use of food stamps, age of household head, tenancy, ethnic background, food shopping habits, and educational attainment. Some of the findings were that the food stamp program recipients (38%) were located in urban areas of the south or northeast, were likely to be female-headed households, and were not elderly. The average household used $48 worth of food per week for 3.3 members. Households receiving food stamps had slightly higher food money values and nutrient intakes per member than did non-recipient households. Food use of the average household was sufficient to meet RDAs for energy and 11 nutrients. (cj).
