How Much Nutrition Do You Need?
ОглавлениеIN THIS CHAPTER
Defining the Recommended Daily Allowances (RDAs)
Addressing the Adequate Intake (AI)
Explaining the Dietary Reference Intake (DRI)
A healthful diet provides sufficient amounts of all the nutrients that your body needs. The question is, how much is enough?
Today, three sets of recommendations provide the answers, and each one comes with its own virtues and deficiencies. The first, and most familiar, is the RDA (short for Recommended Dietary Allowance). The second, originally known as the Estimated Safe and Adequate Daily Dietary Intakes (ESADDI), now shortened to Adequate Intake or simply AI, describes recommended amounts of nutrients for which no RDAs exist. The third is the DRI (Dietary Reference Intake), an umbrella term that includes RDAs plus several innovative categories of nutrient recommendations: EAR (Estimated Average Requirement), AI (Adequate Intake), and UL (Tolerable Upper Intake Level).
Confused? Not to worry. This chapter spells it all out.
