Yes and no,
I cannot drink a glass of milk but can still eat yoghurt, hard cheeses and some ice creams...to a certain degree.
Soft cheeses are deadly but goat and sheep's milk cheeses are fantastic for me and my pouch.
Yes, most colonless people tend to be lactose intollerant but not all of us...I didn't do very well on diary pre-pouch either so it is no big change for me.
By the way, a lot of people can get reactions other than diarreah from milk products...all sorts of skin afflictions are attributed to milk usage too...stop the milk and the excema goes way.
