Lactaid Milk is the way to go! I don't drink milk, per se, but I eat cereal a lot. And I've been using fat-free, lactose-free, calcium renriched Lactaid milk- it's the ebst! Tastes fine in a bowl of cereal/oatmeal or a smoothie, no digestive issues at all, plus you get the added calcium which is good for people who've been on prednisone (I have, may times). I think it comes in 2%, whole, & skim varieties- also not calcium enriched. I used to drink tons of soy milk years back, but just stopped. This was way before my UC was diagnosed, so I don't know if it had any effect at all on it. And I also eat pnut butter crackers for lunch at least 2-3 times a week, peanut butter with Ritz crackers. Pnut butter is a really good way for someone with UC to get protein & fat.
