The Food Safety and Standards Authority of India (FSSAI) has asked all food businesses, including e-commerce food business operators (FBOs), to remove claims of A1 and A2 types from the packaging of milk and milk products. The two categories differ in terms of the beta-casein protein (a major component of cow's milk) the product may contain.  

The A1 category of milk and milk products is consumed more than A2 category products. It is generally found in the milk from northern Europe (Sweden, Denmark, Finland, Norway etc) cows and the milk has a higher fat content and calorie count. Some studies also suggest that A1 products can cause diabetes and heart issues.
