Since diarrhea is a big part of having Crohn's Disease, I get a lot of traffic to this blog from people looking for foods that are ok for IBD, and specifically combat diarrhea. This information is all over the web but I thought I would reproduce it here.
The BRATTY Diet - Foods That Fight Diarrhea
Bananas - Healthy and rich in soluble fiber.
Rice - Plain cooked rice helps soothe the digestive system. Also acts as a bulking agent.
Applesauce - Make it without the peel. Unsweetened is best.
Toast - Easier to digest than bread. Helps neutralize stomach acid. Try eating it plain.
Tea - Green tea is best. Unsweetened decaf.
Yogurt - Plain yogurt is the best for this. It also helps replenish healthy gut bacteria.
And there you have it. Foods rich in soluble fiber are generally a good bet. I have also found Cream of Wheat to be a good option when my stomach is troubled. Also switching to rice milk rather than dairy can also help. Keep in mind you don't want to eat only these foods for a long period of time - you will not be getting proper nutrition.
Anyone have foods that they have found helpful?
