Recommended dietary intake

Definition

Recommended Dietary Allowance is the absolute quantity of all the nutrients required by an average individual. This can vary from person to person, based on their age group, gender, and health condition. The RDA is the estimated amount of nutrients including the calories, proteins, lipids, vitamins and minerals prescribed per day. RDA is the necessary amount of nutrients for the maintenance of bodily activities and good health. It is usually recommended by the Food and Nutrition Board in India.

 

Nutrients

Nutrients are divided into macronutrients and micronutrients. Macronutrients are required in large quantities measured by Grams and Kilograms. Macronutrients are calories, proteins, and fats. Micronutrients are required in smaller quantities and these belong to vitamins and minerals. The following table depicts the RDA for different age groups and populations.
