- (b)) Briefly explain the concept of Recommended Dietary Allowances (RDA) and Estimated Average Requirement (EAR) (150 words)
- (c)) What is the purpose behind setting the dietary guidelines? (100 words)
- Nutrient requirements are influenced by physiological state (age, sex, pregnancy, lactation).
- Physical activity level, body size, and health status (illness, disease) are key determinants.
- Genetic factors and environmental conditions also contribute to varying nutrient needs.
- EAR (Estimated Average Requirement) meets 50% of healthy individuals' needs, used for groups.
Answer: Nutrient requirements are highly variable, determined by an individual's unique physiological state, lifestyle, and health status. Understanding these determinants is crucial for tailoring dietary advice. Dietary reference values like Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA) provide scientific benchmarks for nutrient intake. Furthermore, national dietary guidelines translate this scientific knowledge into practical, food-based recommendations to promote overall...
