Key takeaways
- Plain white, red, and yellow-fleshed potatoes are low FODMAP at generous portions (300 g or more).
- Potato skins contain slightly more FODMAPs but remain safe at normal eating amounts.
- The problems arise with additions: garlic, cream, butter substitutes, or onion.
- Potato crisps (plain, salted) are low FODMAP — flavoured varieties with onion or garlic powder are not.
Potato is one of the great consolations of the low-FODMAP diet. At a time when so many foods require careful measuring and label-reading, plain potato just works — at a satisfying, no-fuss portion.
