That is weird to me. Lactose intolerance has absolutely nothing to do with casein, that is one thing. I have no idea what is bad about casein - btw I am bp asymptomatic drinking lots of milk and kefir and eating lots of yogurt and some farmer's cheese - but I do know that casein and lactase are two completely different animals.

Second, if you are able to "cheat", you are not THAT lactose intolerant. If you were THAT lactose intolerant, you would literally be unable to tolerate dairy. You are probably like me: I drink Lactaid milk but I can have all fermented dairy: cheese, farmer's cheese, yogurt, and kefir. This is not suprising: fermented dairy does not contain that much lactose and whatever little there is, I am able to digest. I also am fine drinking lattes or cappuccinos with regular milk. So I must be mildly lactose intolerant. You too, maybe?
