Food intolerance scanner
One profile, every intolerance you track — FODMAP, histamine, lactose, fructose, gluten and more — checked against a product in a single scan, with the reason behind each match.
What a food intolerance scanner does
Rather than checking one ingredient category at a time, this scanner runs a product’s full ingredient list against every intolerance area active in your profile at once — FODMAP, histamine, lactose, fructose, gluten, salicylate, oxalate, purine and tyramine are all covered in our food intolerances guide. If you’re mainly focused on one area, our dedicated FODMAP, histamine and lactose scanners walk through each in more depth.
Who this is for
Anyone tracking more than one intolerance, or still narrowing down which ingredients are relevant to them — often alongside an elimination process guided by a dietitian or doctor. FoodBuddy doesn’t diagnose an intolerance or tell you which foods are safe; it makes the ingredient list legible against the areas you’ve told it matter, so the physical decision stays yours.
Set your profile once — switch on every intolerance area that applies, each with its own sensitivity level.
Check a product — scan the label, search the database, or look it up by barcode.
Read the breakdown — every matched ingredient shows the label term, which area it triggered, and the match type.
Why checking everything at once matters
Ingredients rarely respect category boundaries — a single sauce can carry a FODMAP-relevant onion powder, a histamine-linked vinegar and a lactose-linked whey powder in the same six lines. Running one scan against your whole profile, instead of re-reading the list separately for each concern, is what turns label-reading back into a ten-second habit instead of a research project every time you shop.
Match confidence, shown honestly
Each result is labelled by certainty: a direct match is a known name for something in your selected areas; a keyword match resembles one closely enough to flag but not confirm; an unverified result means the scanner couldn’t identify the term confidently. Full detail is in our methodology — an honest “not sure” beats a false green light.
