Protein shakes have become a basic part of anyone's diet who is serious about woorking out, especially if they are weight training and hoping to bulk up and build muscle while losing fat. But are there health risks with these shakes and protein powers that people don't know about?

Also the "Oh Yeah" shakes on occasion. For more details on the consumer reports study see below. And make sure to read the comments underneath the article for countering perspectives.
