Final answer:
The statement that the Acceptable Macronutrient Distribution Range (AMDR) provides guidance on reducing chronic disease risk and ensuring nutrient intake is true. RDAs and DRIs establish nutrient and food component intakes necessary for optimal health and to cater for individual needs.
Step-by-step explanation:
The statement that the Acceptable Macronutrient Distribution Range (AMDR) is a range of macronutrient (protein, carbohydrates (CHO), and fat) intake, as percent of energy, associated with reduced risk of chronic diseases while providing for recommended intake of essential nutrients is true. The AMDR is designed to provide dietary guidance to reduce the risk of chronic diseases while ensuring sufficient intake of essential nutrients. Macronutrients such as carbohydrates, proteins, and lipids are needed by the body in relatively large amounts compared to micronutrients like vitamins and minerals.
Recommended daily allowances (RDA) are established to provide guidelines for the intake of various nutrients necessary for optimum nutrition. RDA values are determined for different groups, including infants, children, adults, pregnant and lactating women, accommodating various health conditions and stages of life. The RDAs offer a safety margin to cover the nutritional needs of the general population.
Dietary Reference Intakes (DRIs) and Dietary Guidelines both aim to promote health and reduce the risk of disease, but serve different purposes. DRIs provide quantitative guidance on the amounts of nutrients or food components needed to benefit health, while Dietary Guidelines offer qualitative advice about diet for chronic disease prevention.
