I just made a comparison between a food supplement and regular milk. One portion of a whey protein drink (150 ml or half a glass) contains 17 grams of proteins. Now if I drink big 2 glasses of regular low-fat milk, I get 20 grams of proteins. What's the catch? Can I just drink 2 glasses of milk instead of half a glass of Whey protein? PS: I like milk very much. Cheers, T.
