Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores sweet potato at a serving of 1/2 cup cubed (75 g); at 3/4 cup (112 g) 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.

How much is OK?
This food's verdict depends on the serving. The bands below show where the load builds, group by group.
Fructans
Re-tested in 2025: the limiting group is now fructans, not mannitol, and newer figures allow larger serves than this grid shows — the bounds here hold the conservative line while sources settle. Roasting or mashing does not change the load.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
