Importance of Dietary Reference Intakes (DRIs) in Planning a Healthy Diet
What are the key components of Dietary Reference Intakes (DRIs) and why are they important in planning a healthy diet?
Choose the correct option:
a) Estimated Average Requirement (EAR)
b) Recommended Dietary Allowance (RDA)
c) Adequate Intake (AI)
d) Tolerable Upper Intake Level (UL)
e) Estimated Energy Requirement (EER)
f) Acceptable Macronutrient Distribution Range (AMDR)
The Key Components of Dietary Reference Intakes (DRIs) and Their Importance
The Dietary Reference Intakes (DRIs) consist of six essential components that provide quantitative advice for nutrient intake. These components play a crucial role in planning and assessing nutrient intakes to promote health and prevent chronic diseases.
Explanation:
The six components of Dietary Reference Intakes (DRIs) are:
a) Estimated Average Requirement (EAR): This represents the average daily nutrient intake level estimated to meet the requirements of half of the healthy individuals in a particular life stage or gender group.b) Recommended Dietary Allowance (RDA): The RDA is the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage or gender group.
c) Adequate Intake (AI): The AI is used when there is insufficient scientific evidence to establish the EAR and, consequently, the RDA. It represents the daily average nutrient intake level that appears to sustain a defined nutritional state.
d) Tolerable Upper Intake Level (UL): This is the highest average daily nutrient intake level likely to pose no risk of adverse health effects to almost all individuals in a particular life stage or gender group.
e) Estimated Energy Requirement (EER): The EER is the average dietary energy intake that is predicted to maintain energy balance in healthy, normal-weight individuals of a defined age, gender, weight, height, and level of physical activity consistent with health.
f) Acceptable Macronutrient Distribution Range (AMDR): The AMDR specifies the percentage of total energy intake that should be derived from carbohydrates, proteins, and fats to reduce the risk of chronic diseases while providing an adequate intake of essential nutrients.
