Portion-dependent
Low FODMAP only up to the serving size listed — larger servings stack.
Safe serving
Half a cob, about 38 g
FODMAP group responsible
- Sorbitol — Polyols. Stone fruit, avocado, and most sugar-free products.
- Fructans — Oligosaccharides. Wheat, onion, garlic. The most common trigger and the hardest to avoid.
Why
Low FODMAP at half a cob. Note that corn the vegetable and corn products are different questions — polenta, cornflour and corn tortillas are all FODMAP-free, while the kernels are portion-limited.
What to use instead
Polenta or cornmeal
Milled corn has no ceiling.
Recipes using sweetcorn
Crisp Rosemary Polenta Chips
