How many Asacol are you taking? Are you taking any other meds? If you've been reading through the posts, you'll note that everyone is different in what they can or cannot eat -- I highly suggest you start a list of what bothers you and what you cannot eat. I know for me that sugar in particular bothers me, so I try to limit it. The other thing is fried foods. I can eat most everything else, except in moderation. The Aloe juice might also be causing some issues; if you go up above the blue bar and search in the Google Search for Aloe Juice, UC, you should get some threads on it that might give you a bit more information. It sounds like you might need to be Gluten Free if the Vanilla Meal replacement doesn't seem to bother you. Good luck and hope you get to feeling better very soon.
