Describe the standard that the national research council-national academy of sciences, food and nutrition board uses to determine the recommended dietary allowance (rda) for the daily intake of elements that are not produced by the body.

The recommendations are derived from healthy individuals consuming a 2000-calorie daily diet balanced from the 6 basic food groups.

Explanation:

2000 calories a day is the amount indicated for an adult who wants to maintain their weight. This amount of calories is recommended by the National Research Council - National Academy of Sciences, Food and Nutrition, based on the diet of healthy individuals who consume a balanced 2000-calorie daily diet of the 6 basic food groups.

An average adult person needs to eat about 2000 calories a day to maintain and 1500 calories to lose a pound of weight per week. This amount of calories is also ideal for keeping us energized throughout the day and for maintaining nutrition levels in the body when food is balanced.
