Ingredient checker
Paste, search, or scan a full ingredient list and see exactly which entries match the intolerances, allergens and interest areas in your profile — with the reason for each one.
What an ingredient checker actually does
An ingredient checker takes the full list printed on a product — often fifteen or twenty items long, written in food-industry shorthand — and compares it term by term against the things you care about. FoodBuddy’s checker works from either a live scan of the physical label or a product already in the database, so you can check something before you’re standing in the aisle with it.
The practical value shows up before you’ve committed to a product, not after. Reading a full ingredient list once, in the abstract, tells you little — but comparing that exact list against your own profile, term by term, converts twenty unfamiliar words into the handful you actually need to think about. That’s the difference between reading labels as a chore and reading them as something that takes ten seconds and answers the question you actually had.
Why a plain read-through isn’t enough
The same ingredient can appear under several names: milk protein as casein or whey, wheat-derived starch under an E-number, soy hidden inside “lecithin.” Reading the list once and scanning for a word you recognize misses these. FoodBuddy’s checker matches against a dictionary of alternative names, not just the headline term, and shows you which name triggered each match.
This gap between what’s printed and what’s recognizable is exactly where avoidable mistakes happen — someone confidently buys a product because they didn’t see the word they were looking for, when the ingredient was there all along under a name they’d never learned. A checker that only pattern-matches the obvious term is barely better than the read-through it’s meant to replace.
Set your profile once — pick the intolerances, allergens and interest areas that apply to you, with a sensitivity level for each.
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, the match type, and which area it triggered.
Why a second pass matters
Even careful shoppers develop blind spots: a brand they’ve trusted for years quietly reformulates, a seasonal variant swaps one sweetener for another, or a multipack uses a different supplier than the single item. None of that shows up unless the current label is checked against the current list, every time, rather than relied on from memory. That’s the case for running a fresh check even on products you already “know” — it costs a few seconds and catches the exceptions memory can’t.
Match confidence, shown honestly
Not every match is equally certain. FoodBuddy labels each one: 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 checker couldn’t identify the term confidently. Full detail on how this works is in our methodology.
This honesty matters because a false sense of certainty is worse than an acknowledged gap: a shopper who trusts an unverified match as though it were confirmed is taking on more risk than one who knows to go double-check the physical label. Showing the match type alongside every result keeps that distinction visible instead of quietly flattening every hit into the same green checkmark.
