I was told that raw fruits and veggies weren't good for my diet? Like their hard to digest when you have UC. I haven't personally tried.
Generally speaking, raw foods do take a longer time and more digestive effort/energy than cooked foods do. Flares tend to speed up our digestive tract so they might give us more trouble. In remission than no worries.
There's no define rights or wrongs for everyone universally with uc. Your results will vary, one size doesn't fit all, and all of that sorta stuff..
