Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores sourdough spelt bread at a serving of 2 slices (~80 g); at n/a - published guidance stops at the 2-slice serve rather than giving a tested middle band 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
Spelt flour starts out lower in fructans than modern wheat, and a traditional long wild-starter ferment lowers it further, so this is one of the more generous wheat-family breads. Published 2-slice serves range from about 52 g to 90 g depending on loaf and slice size, so weigh dense or oversized slices instead of counting them. The tested form is 100% spelt sourdough - loaves blended with regular wheat flour behave more like the wheat portion, and quick-proofed spelt loaves sold as sourdough-style skip the fermentation that does the work.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
