These recommendations, which aciciress issues such as the neeci to improve estimates of nutrient requirements and the quality of clietary intake ciata, are reiterated here. The recommendations in this chapter have been prioritized, and those presented uncler the first heacling should be given the highest priority for research and development funding.

A nearly complete distribution shift may be possible with interventions involving mandatory fortification of whole cliets that have limited variety, such as emergency relief rations, or cliets with a limited number of widely consumed staple foocis in economically clepresseci areas of the world. Successful government-sponsoreci fortification of varied cliets, as is the case in the United States and Canada, clepencis on an appropriate selection of food vehicles that are similarly consumed by most people.

Information is generally minimal or lacking on the nutrient intake distributions of other groups such as children in different ciaycare settings, hospitalized patients, or residential longterm care homes or other institutional settings (with or without selective menus)

Research is neecleci to determine the practical usefulness of planning for a target nutrient density, to determine if the applicability of the nutrient density approach is limited to situations with precletermineci food allocations or restricted food choices (e.g., emergency relief rations) , and to determine if this approach would be practical in situations offering a wicle variety of food choices where the nutrient density is more clepenclent on food selection than on total food access to meet energy neecis.

Plans for the Fourth National Health and Nutrition Examination Survey attempt to aciciress some of these issues. Despite the difficulties in maintaining a supplement composition database for the rapidly changing market, investigation of better methods of quantifying supplement intakes is a highpriority research area.

From page 152... ...
Changes in recommended intakes of various nutrients, combined with rapid changes in the amount and number of nutrients and types of foods that are fortified (particularly in the United States) , necessitate review of existing food guides and continuation of the periodic review of dietary guidance such as the Dietary Guidelines for Americans and Canada's Guidelines for Healthy Eating.

However, in both cases, the emphasis should be on food sources of nutrients. In the United States fooci-baseci menu planning guides have long been part of specifications for professionals to use in planning the food offered in various nutrition programs such as the National School Lunch Program.

Adjustment factors for considerations such as body size, physical activity, and intakes of energy and other nutrients may be appropriate but are often unknown. Studies to evaluate nutrient requirements or adverse effects should provide individual data where possible to allow estimation of their distributions.

In aciclition, information on the distribution of adverse effects via closeresponse ciata (e.g., risk curves) would allow greatly expancleci applications of the UL, particularly for population groups.
