The good research and media press on dairy products keeps rolling out! This latest study indicates that milk protein is better at building muscle mass than soy protein.

Weightlifters may want to raise a glass, researchers at Canada’s McMaster University say. A study there found that milk protein is significantly better than soy at building muscle mass. “We were really impressed by how much greater the gains in muscle protein with milk were,” says lead researcher Sarah Wilkinson.

It compared how much muscle protein young men gained after completing a heavy-weight workout followed by consumption of equivalent amounts of protein as either skim milk or a soy drink. Specifically, the authors said that men who drink skim milk gain almost twice as much muscle in 10 weeks as those who drink soy. Another author said milk and soy had been considered equivalent proteins. The researchers were uncertain why milk was so much more effective.
