Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores blueberry at a serving of 1/4 cup (about 40 g); at 1 cup or more (about 125 g) 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.
Fructans
Around 60 g fructans reach the high band; an older 1-cup figure still circulates but predates the current, much smaller numbers — measure rather than free-pour.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
