1. Correct. Dietary Reference Intakes (DRIs) consist of Recommended Dietary Allowances (RDAs), Adequate Intakes (AIs), and Upper Limits (ULs). AIs are similar to RDAs except they deal with nutrients about which there are insufficient data to be certain (RDA status). ULs are guidelines for avoiding excesses in nutrients where excess is toxic. Green leafy vegetables, whole grains, and fruit go a long way, but they're not the whole nutritional story.
