Milk Good or Bad

I have done a little milk research in my spare time (LOL - of which I have very little).  But when it is in the interest of Wellness... then I make time.
There are milk interolerance and milk allergies.   Which cause very different reactions.   To sum very briefly milk intolerances are very common, and cause problems with digestion, and make cause behaviour problems as well.   Milk allergies, usually cause a person to throw up.   Now when it comes to children it is actually a very low percentage that ever have milk allergies, and generally out grow it by the time they are 5 or 6 years old.   And would be extremely rare to develop the allergy later (but not impossible).   But with my son, he seems to be doing okay again, long as he drinks his milk when he is eating food, and not drinking it on a empty stomach.
Anyways with that said I found a couple of interesting articles which I have included links below:
