Can I eat french fries with ulcerative colitis?
During a flare: Usually avoidIn remission: Caution
French fries are deep-fried in oil, so they carry the same fat-load and peroxidized-fat concerns as other fried foods, and greasy, fried potato products are more commonly reported as consumed by people with IBD than by those without it in survey data, suggesting they're a food people notice reacting to. Restaurant fries are also often high in sodium.
During a flare
Deep-fried fries are often harder on the gut during a flare because of their fat content; some people find baked or air-fried potatoes easier to manage.
In remission
Portion size and preparation (baked versus deep-fried) tend to matter most when reintroducing fries in remission.
Ways to make it gentler
- Bake or air-fry potato wedges instead of deep-frying
- Choose a smaller portion at restaurants
Safer swaps
baked potato wedges · mashed potatoes · roasted sweet potato
