Fruit with skin

An apple a day may keep the doctor away, but if it isn't peeled, it can cause major digestive distress for someone with Crohn's.

The same goes for vegetables with edible peels, like cucumbers. Strip them off before you eat them. In fact, some people with Crohn's find they can eat raw fruit and even some raw vegetables if they've been peeled.

In general, cooked or canned fruits and vegetables are often a better choice than raw.
