According to this Whey Protein site, Milk is highly nutritious but only contains about 1% of whey protein. I call BS because all other sites on google say that Milk contains about 20% whey and 80% casein. So i'm thinking they just want to sell their whey products.
Anyways just looking for other alternatives because I hated whey protein shakes, it gave me gas, acidic stool, diarrhea, taste bad
