Since childhood, we are told to drink lots of milk in order to grow, and we keep drinking milk as we get older because we need it for our bones, right?  And then of course there is the huge propaganda of "Got Milk?" in the US, that no doubt has encouraged people to keep drinking milk, making us believe that we need it, in order to get our much needed calcium and vitamin D.

So why are people starting to cut down on dairy?  Why are many nutritionists and holistic doctors talking about dairy as being potentially harmful to adults?
