Low FODMAP Ingredient Label Checker

Why product labels need a different kind of check

A full ingredient label can contain several small FODMAP contributors that are easy to miss when reading quickly. This label checker groups detected ingredients by risk and category so you can see whether the product has one obvious concern or several smaller contributors that may stack.

• Use it for packaged snacks, sauces, bars, breads, dairy alternatives, spice mixes, and ready meals.
• Look for repeated patterns such as onion plus garlic, dairy solids plus inulin, or fruit concentrate plus polyol sweeteners.
• Treat vague label terms such as natural flavor as uncertain rather than automatically safe or unsafe.

What the overall risk estimate means

The overall estimate is intentionally simple. It is based on the highest-risk matched ingredient in the static dictionary, not on a lab-tested serving-size database. That makes it fast and transparent, but it also means the result should be read as a screening signal.

• Low estimate: no local dictionary matches were found, but the product still may not suit everyone.
• Medium estimate: at least one ingredient needs portion-size or tolerance context.
• High estimate: one or more commonly risky ingredients appeared in the label.

Common label patterns to review closely

Some product categories are more likely to include hidden FODMAP sources. Protein bars often use chicory root fiber or inulin. Savory sauces often contain onion or garlic powders. Sugar-free products may use polyols. Fruit-sweetened foods can include apple or pear concentrates.

• Bars and cereals: inulin, chicory root, FOS, honey, fruit concentrates.
• Sauces and broths: onion, garlic, garlic powder, onion powder, wheat-based thickeners.
• Dairy products: lactose, milk powder, whey solids, fruit preparations.
• Sugar-free sweets: sorbitol, mannitol, xylitol, maltitol.

A practical way to use this checker

Start by checking whether the product has obvious high-risk ingredients. Then consider how much you would actually eat and what else is in the meal. If the product is just one part of a larger plate, use the stacking calculator or the app to think about the full meal instead of the label alone.
