Re diet, in my 35 yrs of having Crohn's, this is what I've found works for me.
During flare up:
Fast or eat very little
During times of moderate symptoms:
Low fibre
Low sugar
Low fat
Lots of ginger tea, peppermint tea
Simple meals such as steamed fish, rice, steamed carrots, bananas, boiled or baked potatoes, homemade soup (clear or pureed)
Non dairy milk & yoghurt (cashew, almond, soya, coconut)
No dairy (except kefir) or gluten
No canned food or ready meals
No chilli, curry, onion, garlic, beans
No alcohol
No restaurant meals or take-aways
During remission
Moderate fibre
Low sugar
Moderate fat
Fish, chicken, slightly wider range of fruit and veg - asparagus, lettuce, cuc, apples, berries,
Porridge
Gluten free bread, crackers, cereals
Non dairy milk & yoghurt
Almond butter
Low alcohol (2 or 3 drinks a year!)
As far as poss, no gluten or dairy (except kefir)
For a couple of months I have been having a small amount of kefir daily. It's dairy, but it's so high in probiotics I can tolerate it. The kefir apparently changes your bowel bacteria and I believe it is possibly helping me.
I'd love to hear others' dietary experiences for Crohn's. I'm still learning!
