Stop guessing what
you can eat with IBS.

A three-phase elimination diet developed by Monash University for IBS. Phase 1 removes high-FODMAP foods for 2–6 weeks. Phase 2 reintroduces each FODMAP group one at a time to find your triggers. Phase 3 is a personalised long-term diet that only restricts the FODMAPs you actually react to.

The menu scanner, recipe fixer and food guide are completely free — no account needed. The meal and symptom tracker is also free; you just need a free account so your data syncs across devices.

Yes. Gutsy is built around Monash University FODMAP research and follows their three-phase protocol. We're not affiliated with Monash and don't republish their proprietary database. For definitive per-serving thresholds, use the official Monash app alongside Gutsy.

Paste a restaurant URL, upload their PDF, or paste the menu text. Gutsy fetches the actual menu from the restaurant's site, then rates every dish safe, modify, or avoid — with the exact words to use when ordering.

No. Gutsy helps you track, log and stay consistent between appointments — but the low-FODMAP diet should be done under a qualified dietitian's guidance, especially during reintroduction.

Yes. The food search tool shows FODMAP categories and serving thresholds, which is especially useful during reintroduction when you're testing one FODMAP group at a time. The symptom tracker helps you log reactions against specific meals and FODMAP loads.

For most people with IBS, yes — garlic and onion are two of the highest-FODMAP foods and among the most common triggers. The good news: garlic-infused oil is completely safe (fructans are water-soluble, not oil-soluble), and the green tops of spring onions are low FODMAP. Gutsy's recipe fixer makes these swaps automatically.

Gutsy uses Claude AI to identify high-FODMAP ingredients and suggest evidence-based swaps grounded in Monash research. It flags its own confidence level — high, medium, or low — so you always know when to double-check with the Monash app or your dietitian.

Gutsy focuses on FODMAP content rather than gluten content specifically, but the two often overlap — gluten-free versions of bread, pasta and crackers are frequently also low FODMAP (at appropriate serving sizes). Always check certified GF labels if you have coeliac disease, as cross-contamination rules still apply.

You can paste the menu text directly into the scanner — from a photo, a PDF copy, or typed out from a paper menu. Gutsy analyses whatever text you give it, not just URLs.
