Low FODMAP Diet Food List: Printable Yes/No Guide

The low FODMAP diet, developed by Monash University, is the most evidence-based dietary therapy for IBS, with ~70% of patients reporting symptom improvement in randomized trials. It's also widely used alongside SIBO and post-infectious gut conditions.

This guide gives you the complete yes/no food list, organized by category, with portion thresholds — because for many "moderate" foods, dose is what determines tolerance.

Medical Disclaimer: The low FODMAP diet is a 3-phase therapeutic diet, not a long-term eating pattern. Phase 1 (elimination) should not last more than 2–6 weeks. Reintroduction and personalization are essential. Work with a FODMAP-trained dietitian when possible.

What FODMAPs Are

FODMAPs are short-chain carbohydrates poorly absorbed in the small intestine, then fermented by colonic bacteria — producing gas, bloating, pain, and altered bowel habits in sensitive individuals.

The 3 Phases — Don't Skip Them

  1. Elimination (2–6 weeks) — strict low FODMAP only.
  2. Reintroduction (6–8 weeks) — challenge each FODMAP group one at a time.
  3. Personalization (lifelong) — only restrict the FODMAPs you react to.

Skipping phases 2 and 3 causes microbiome harm and unnecessary restriction.

✅ Vegetables — Low FODMAP (Eat Freely)

❌ Vegetables — High FODMAP (Avoid in Phase 1)

Tip: Use garlic-infused olive oil — fructans are not oil-soluble, so the flavor transfers but the FODMAPs don't.

✅ Fruits — Low FODMAP

❌ Fruits — High FODMAP

✅ Proteins (All Plain Animal Proteins Are FODMAP-Free)

❌ High FODMAP Proteins

✅ Grains — Low FODMAP

❌ Grains — High FODMAP

✅ Dairy — Low FODMAP / Lactose-Free

❌ Dairy — High FODMAP

✅ Nuts & Seeds (Watch Portions)

❌ High FODMAP Nuts

✅ Sweeteners

❌ Sweeteners to Avoid

Sample Low FODMAP Day

Use Nutrtion.io as Your FODMAP Filter

Memorising portion thresholds is the hardest part of the FODMAP diet. Scan any food in Nutrtion.io and it tells you the FODMAP status — including the safe portion size — so you can stay in the elimination phase without constantly checking the Monash app.

FAQ

Is the low FODMAP diet for life? No. Phase 1 should last 2–6 weeks. Long-term restriction harms the gut microbiome.

Can I do it without a dietitian? You can, but reintroduction is significantly harder solo and most people end up over-restricting.

Is low FODMAP the same as gluten-free? No. Wheat is high in fructans (a FODMAP), not just gluten. You can eat sourdough spelt while avoiding regular wheat bread.

Does low FODMAP help SIBO? Yes — it reduces fermentable substrate. Often combined with antimicrobial therapy. See our SIBO diet guide. If constipation is your main symptom, read methane SIBO foods to avoid; if you graze between meals, the low fermentation diet is usually the better starting point.
