Button mushrooms
Rating: depends on portion · Trigger subgroup: Mannitol
At a 7 g portion: green light
Lights per subgroup
- Fructans 0.02 g · green light
- GOS 0 g · green light
- Excess fructose 0 g · green light
- Lactose 0 g · green light
- Sorbitol 0.01 g · green light
- Mannitol 0.18 g · green light
fructans and GOS are evaluated together (oligosaccharide sum) · sorbitol and mannitol are evaluated individually and combined — the worse result wins
Green boundaries come from the scientific sources; the amber (1–2× the cutoff) and red (>2×) bands are an app estimate.
