I drink milk too and have forever. I like it and am tolerant of it. It is a good source of protein and calories, so if you can drink it and not have the gut probelms, do so. Milk with dinner is a favorite of mine.
I don't think it is contradictory of today's diets. There are some that say avoid it and others that say dirnk it. I personally believe that it is beneficial towards your health, unless of course you are lactose intolerant.
