Drink whole, raw milk. Why? Because raw milk has the natural cultures and digestive enzymes in it necessary for your body to best utilize all of its nutrients, especially the protein in it. The fat in the raw milk is also incredibly beneficial, not only is it a naturally high source of CLA, but the fat in the milk helps to slow its digesting, which is important since the protein in milk is casein(a naturally slow digesting protein). The fat in milk also helps lower its glycemic index, meaning you will not get as much of an insulin response, and you are less prone to store fat. Pasteurized milk is just dead milk, it is really wortht he extra money to drink the raw stuff. I got through about two gallons of raw milk a week, and I am currently at 6% bodyfat. Raw, whole milk makes you strong, not fat
