Low FODMAP ingredient swaps

Keep the recipe. Change the trigger.

Search an ingredient to find practical substitutes chosen for a similar role in cooking, not just a random low FODMAP food.

Read results with portion context. Individual tolerance varies, and recipe totals can create FODMAP stacking. These tools organize educational information rather than diagnose symptoms.

Why this tool

Answers built from a structured database.

Suggestions combine a curated substitution library with the FODMAP Check database. Options are organized around the job an ingredient performs instead of returning unrelated low FODMAP foods.

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.
