About Histamine Intolerance Scanner
Is this food right for you? Scan a product's ingredient list or barcode and see at a glance what is well or poorly tolerated with histamine intolerance. SCAN PRODUCTS • Take a photo of the ingredient list: the text is read right on your phone, in English or French • Or scan the barcode: the ingredients come from the Open Food Facts database • Every recognized ingredient gets a rating from 0 (well tolerated) to 3 (very poorly tolerated), additives and E numbers included (E330, E621…) • Words like "smoked", "aged", "cured", "fermented" or "canned" on the label are taken into account FRESHNESS CHANGES EVERYTHING • Histamine builds up over time: fresh minced meat is well tolerated, the same meat kept a few days in the fridge much less so • The app warns you whenever a food can get riskier: pre-packed, leftovers, fish that isn't very fresh, aged cheese… • "Cautious scan" option: when the label says nothing, the scan uses the worst case 675 RESEARCHED FOODS • Meat, fish, dairy, fruit, vegetables, grains, drinks, spices and additives • Ratings aligned with the SIGHI food compatibility list and backed by published content measurements • For each food: why it can be a problem (high in histamine, other amines, liberator, DAO blocker), variants by preparation, and sources you can open • When data is thin, the app says so YOUR OWN EXPERIENCE • Rate how you tolerate each food: your rating shows next to the reference rating, in lists and scan results • Find all your ratings in a dedicated tab SIMPLE AND PRIVATE • Free, no ads, no account needed • Your ratings stay on your phone • In English and French This information is a guide only and does not replace advice from a doctor or dietitian.
