While I agree that many people do have an intolerance to lactose, many people who think they are intolerant are actually not intolerant to the lactose but may in fact be intolerant to the casein and indeed many people are intolerant to both. Lactose intolerance is quite specific, occurring in the large intestine. A simple test for lactose intolerance is to drink a glass of cows milk then if you get diarrhea two hours later you're probably intolerant to lactose. If you think you may have a lactose intolerance see your doctor
