Question

multiple choice
the adult amdr for carbohydrates is 45 to 65% of total energy intake.
a group of scientists at the academy of nutrition and dietetics developed the dris.
nutrient requirements are the same, regardless of a persons age or sex.
recommended dietary allowances meet the nutrient needs of 50% of healthy people.

Explanation:

• For the first option: The Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates in adults is indeed 45 - 65% of total energy intake, so this statement is correct.
• For the second option: The Dietary Reference Intakes (DRIs) were developed by a committee of experts from multiple institutions, not just a group at the Academy of Nutrition and Dietetics, so this is incorrect.
• For the third option: Nutrient requirements vary based on age, sex, physiological state (e.g., pregnancy), activity level, etc. For example, children have different calcium needs for growth compared to adults, and men and women may have different iron needs, so this is incorrect.
• For the fourth option: Recommended Dietary Allowances (RDAs) are set to meet the nutrient needs of nearly all (97 - 98%) healthy people in a specific life - stage and gender group, not 50%, so this is incorrect.

Answer:

The adult AMDR for carbohydrates is 45 to 65% of total energy intake.
