Onion

Quick verdict

Status: unknown - for your review.

Confidence: low (AI-prepopulated from general food properties, not your own reactions).

Claimed concern

Onion (Allium cepa). High in fructans (FODMAP) that feed microbes; contains quercetin (an antihistamine) yet can itself be a trigger, especially raw. Not a nightshade.

Decision notes

Caution mainly for FODMAP reactions; cooked is gentler than raw.
