Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores corn at a serving of 1/2 cob (38g) or 1/3 cup kernels; at 1 whole cob and above it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
Based on published FODMAP research and reviewed reference data. Informational only — not medical advice. Tolerance is individual; verify with a dietitian during the elimination phase.
How much is OK?
This food's verdict depends on the serving. The bands below show where the load builds, group by group.
Sorbitol
Grams are the kernels, not the weight of the whole ear, so a single small cob eaten end to end already sits at the top of the range.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
