Hidden FODMAP Ingredients Checker

How the hidden ingredient checker works

Many packaged foods look simple on the front of the package but hide FODMAP-heavy ingredients in the label. This checker scans the pasted text against a local dictionary of common triggers such as garlic, onion, added prebiotic fibers, lactose-containing dairy powders, fruit concentrates, and sugar alcohols.

• Paste the ingredient list exactly as it appears on the package.
• The tool normalizes spacing and punctuation before matching known aliases.
• Detected items show a cautious risk level, likely FODMAP category, and a short explanation.

Ingredients this first version is designed to catch

The starter dictionary focuses on ingredients that frequently appear in sauces, snacks, spice blends, protein bars, cereals, dairy products, and sweetened drinks. It is intentionally conservative: a matched ingredient is a reason to review the label, not a diagnosis or a guarantee that symptoms will happen.

• Fructan sources: garlic, onion, garlic powder, onion powder, inulin, chicory root, FOS, wheat, and rye.
• GOS sources: GOS blends, beans, and lentil-based ingredients.
• Polyols and sweeteners: sorbitol, mannitol, xylitol, maltitol, honey, agave, and fruit concentrates.
• Lactose concerns: lactose, milk powder, skim milk powder, whey, and similar dairy solids.

How to interpret a match

A match means the ingredient appears in the local dictionary. The real-world risk depends on how much is present, where it appears in the ingredient order, the serving you eat, and your personal tolerance. A tiny amount in a long label may feel different from a sauce or snack where the ingredient is central.

• High risk means the ingredient is commonly problematic for many Low FODMAP eaters.
• Medium risk means portion size or processing often matters.
• Unknown risk means the term needs more context than a static matcher can provide.

When to use the app instead

This page is useful for quick browser checks, but shopping decisions often happen while holding a package in a store. The app is better for repeated checks because you can scan or type foods faster, review likely concern notes, and save the result for later comparison.
