Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores canned lentils at a serving of 1/2 cup (46g) rinsed; at 1 cup or more 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.
GOS
Rinsing washes off leached GOS; near the top of the band fructans stack on as well, so overshooting tips high quickly — measure by weight, not eye.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
