active adults need milk as much as kids do. we might stop growing height wise but changes to our body never stops. milk is good for the muscles not cause it have proteins but from the hormones that are in it from the cows that are healthy and are needed for muscle function. also the hormones from cow milk help maintain weight and acts as a fat burner as well. for the subject i drink any milk really. i mostly have 2% but prefer whole milk all the time and i drink about few big glasses a day due to since i'm active and do heavy weight training about 2-3 times a week. only milk i never drink is soy ever since that crap is for chicks and taste horrible and soy milk is actually not great for men either since it contains estrogen hormones.
