Crohn’s Disease Diet

Although there's no evidence to suggest diet plays a role in Crohn's disease, some people have found certain foods aggravate their symptoms. It may be useful to keep a food diary to make a note of the foods you eat and to record the effects they have on your symptoms.

If you notice certain foods make your symptoms worse, avoiding these may reduce your symptoms. However, the total elimination of entire food types, such as grains or sugars, isn't usually recommended.

Some people find that eating six smaller meals a day, rather than three larger meals, improves their symptoms.
