Document Summary
Unit 3 dietary reference intakes and diet-planning guides. Describe the goals of dietary reference intakes (dri). Most people need to focus on only two kinds of dri values: those that set nutrient intake goals for individuals (rda and ai,) and those that define a tolerable upper intake level of safety for nutrient intakes (ul) Defination: the dris are designed for people of all ages-from infants to senior citizens. They are separated into 18 age-gender categories, plus five categories for stages of pregnancy and lactation. They are technical guidelines describing nutrients that are used by scientists researching nutrition and by health professionals to assess diets and provide nutrition advice. Two sets of values specifying intake goals for individuals: recommended dietary allowances (rda) and adequate intakes (ai). Rda is more reputable as it is based on solid experimental evidence and reliable observation.
