Recommended Dietary Allowance (RDA)
Nutrition is a basic human need and a prerequisite to a healthy life. A proper diet is essential from the very early stages of life for proper growth, development and to remain active. RDA represents the nutrients in terms of diets that should be consumed by the population.

In India, the concept of RDA dates back to the 1944. The first attempt to define nutrient requirements was made by Nutrition Advisory Committee of the Indian Research Fund Association now known as Indian Council of Medical Research (ICMR) in 1944. Since then it is revised every 10 years. Current RDA was set in year 2010.
