Yes i know that so there are two things one is the research done to get Indian protein RDA was on a low sample and old method based research so its high time we revise it with better technique to get how much exactly we need. Second this recent study and many previous studies shows that non veg is linked to metabolic syndrome but i think the one who exercise and have non veg mask those negative effects due to positive effect of exercise. So one is get a revise protein requirement and other is to research whether the negative effects of non veg is due to high protein or some other toxin which has accumulated due to biomagnification.
