Why this tool

Answers built from a structured database.

Results come from the structured FODMAP Check database. Each record separates status, serving guidance, portion context and groups such as lactose, fructans, fructose, sorbitol, mannitol and GOS.

Sources and limits

Serving guidance and diet stages are interpreted with resources from Monash University and NIDDK. This tool provides educational information and does not diagnose IBS, SIBO or food intolerance.

FAQ

Frequently asked questions

How much of a food can I eat on a low FODMAP diet?

The amount depends on the food and its FODMAP concentration. Search the food to see its listed low FODMAP serving and how the rating may change at larger portions.

Is a low FODMAP serving a daily limit?

Serving guidance is generally interpreted per meal, not as a daily allowance. Personal tolerance and the combination of foods in the meal also matter.

Why can a food change at a larger serving?

A larger portion can contain more fermentable carbohydrates. Some foods are low FODMAP in smaller amounts but become moderate or high at larger servings.

What should I do if my food is not listed?

Try a simpler food name without a brand, recipe or preparation method. If there is still no result, the food may not yet be available in the database.

Does a low FODMAP result guarantee no symptoms?

No. The result summarizes food data. Individual responses vary with portion size, the complete meal and factors unrelated to food.
