Step-by-step explanation:
The Estimated Average Requirements (EARs) are guidelines that establish the average nutrient requirements to meet the needs of about 50% of a specific population group in terms of their age, sex, and life stage. These guidelines provide an estimate of the amount of nutrients individuals typically need for good health. EARs serve as a baseline for establishing dietary recommendations and are used to evaluate and plan diets at a population level. They are widely used in nutrition research and policy-making to assess nutrient adequacy and guide the development of dietary guidelines.
