IBS (low-FODMAP)

The low-FODMAP diet (Monash University) eases IBS symptoms for many people. It has three steps: replace high-FODMAP foods for 2–6 weeks, reintroduce them one group at a time, then keep only the restrictions you need. It's not meant to be followed strictly for life.

  • The low-FODMAP diet is a short-term test, ideally guided by a dietitian.

How to do the low-FODMAP diet

Quick answer: To do the low-FODMAP diet, step 1: swap high-FODMAP foods for 2–6 weeks, step 2: reintroduce one group at a time, step 3: personalise and cook with flavour.

  1. Step 1: swap high-FODMAP foods for 2–6 weeks. Avoid onion, garlic, large servings of wheat and beans, regular milk, apples, pears, mango and honey; use the low-FODMAP options in the plan.
  2. Step 2: reintroduce one group at a time. Test lactose, fructans (wheat, onion, garlic), GOS (pulses), fructose and polyols over a few days each to find your triggers.
  3. Step 3: personalise. Bring back everything that doesn't trigger you, so your diet stays varied and good for your gut bacteria.
  4. Cook with flavour. Garlic-infused oil, the green tops of spring onions, ginger, cumin and gluten-free hing replace onion and garlic.

Why not stay low-FODMAP forever?

FODMAPs feed healthy gut bacteria. Long-term strict restriction isn't needed and can be harder on gut health, which is why the reintroduction step matters.

Check for coeliac disease first

Ask your doctor to test for coeliac disease before cutting out wheat; the test only works while you're still eating gluten.

Frequently asked questions

Can I eat daal on a low-FODMAP diet?

Small portions of canned, rinsed lentils or chickpeas (about ¼ cup) are low-FODMAP. Large portions of daal, rajma and chana are high.

Is rice low-FODMAP?

Yes. Rice, oats, quinoa, millet and potatoes are all low-FODMAP.

Should I do this with a dietitian?

Ideally yes. A FODMAP-trained dietitian makes the reintroduction step faster and keeps your diet balanced.
