Step-by-step explanation:
The two statements that correctly describe Reference Daily Intakes (RDIs) are:
- These reference values are for individuals over the age of four.
- They are a subset of dietary references for vitamins, minerals, and protein.
RDIs are part of the broader category of Dietary Reference Intakes (DRIs), which include the Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). The RDIs provide a guideline for the required intake of certain nutrients to prevent deficiencies and maintain health, which are calculated for the general population over the age of four. They are not based on a 1,000-calorie intake but are often presented as a percentage of the nutrient requirements based on a 2,000-Calorie a day diet for adults. RDIs do not indicate amounts of artificial flavors, colors, or synthetic substances.
