Recommended Dietary Allowance (RDA)

What to study?

For Prelims: What is RDA?

For Mains: Concerns over fast foods and measures needed.

Context: A laboratory analysis of most packaged and fast food items sold in India has revealed high salt and fat content, in violation of thresholds set by the Food Safety and Standards Authority of India (FSSAI).

The study was conducted by the Centre for Science and Environment (CSE).

The study found that much of Recommended Dietary Allowance (RDA) is used (or exhausted) by eating these foods.

The results show that in almost all the food CSE tested, companies have underreported the amount of transfats in their products.

For Prelims:

What is Recommended Dietary Allowance (RDA)?
