Ingredo.app for soy allergy
Turn on Soy allergy and Ingredo.app hard-blocks every declared source on any food you scan, citing the source behind each flag. Because we cannot detect trace amounts or cross-contamination, the physical label stays authoritative.
Allergen profiles are a hard block, not a soft caution — a declared source turns the verdict to "avoid" outright, rather than nudging the score.
Where an ingredient cannot be verified, the result degrades to "couldn’t verify — check the label". A safety flag never silently becomes a pass.

Common questions
Yes. Highly refined soy lecithin is tolerated by many people with a soy allergy, but the decision is yours and your clinician’s — so we surface it rather than deciding for you.
Soybeans are a source of galacto-oligosaccharides, a FODMAP. The same ingredient legitimately matters to two different people for two different reasons.
