Having said that, lactose-free milk and yogurt are great sources of high quality protein.
I don't drink milk (I use soy milk instead), but it's not due to lactose intolerance. I don't drink it because of what Tung states right here: Cow milk is for cows, not humans. Of course, I'm not very good at being lacto-free. I love yogurt and cheese. I think that makes me only half hypocritical.
