38. What are the dietary reference intakes?
The Dietary Reference Intakes (DRIs) are specific reference values for each nutrient issued by the United States ‘National Academy of Sciences’ Institute of Medicine. The DRIs are the specific amounts of each nutrient that one needs to consume to maintain good health, prevent chronic diseases, and avoid unhealthy excesses.
39. How to use the DRIs
You can use the DRIs to make healthy food choices and plan a quality diet. To meet your needs, your goal should be to meet the RDA or the AI of all nutrients, but not exceed the UL. Whereas the DRIs were released to prevent under nutrition, the Dietary Guidelines for Americans were developed out of concern over the incidence of over nutrition among Americans.
40. What Are the Dietary Guidelines for Americans?
By the 1970s, research had shown that Americans’ overconsumption of foods rich in fat, saturated fat, cholesterol, and sodium was increasing their risk for chronic diseases, such as heart disease and stroke. In 1977, the U.S. government released the Dietary Goals for Americans, which were designed to improve the nutritional quality of Americans’ diets and to try to reduce the incidence of over nutrition and its associated health problems.
