Practical food guide
What to eat, what to limit, and how to bring foods back. Start with simple swaps, then find what works for you.
Step 1 food guide
Compare foods in the same group. These are examples, not “safe” or “forbidden” lists. Always check tested serving sizes: portion, ripeness, processing and the whole meal matter.
Carrot, cucumber, potato, lettuce, bok choy and green beans.
Onion, garlic, cauliflower, asparagus and many mushrooms.
Orange, mandarin, kiwifruit, pineapple and blueberries in tested portions.
Apple, pear, mango, cherries, watermelon and dried fruit.
Rice, oats, quinoa, plain rice cakes and corn or rice pasta.
Many wheat or rye breads, wheat pasta and wheat-based cereals.
Lactose-free milk, hard cheese, feta and calcium-fortified almond or rice milk.
Regular milk, yoghurt, custard and ice cream when lactose is not tolerated.
Plain fish, chicken, meat, eggs, firm tofu and suitable portions of peanuts.
Kidney beans, split peas, baked beans, cashews and pistachios in common servings.
Garlic-infused oil, chives, herbs, maple syrup and table sugar in moderate servings.
Honey, high-fructose corn syrup, sorbitol, mannitol, xylitol and maltitol.
Use the Monash University FODMAP Diet App for tested portions. Several borderline servings in one meal can add up. Check sauces, stocks and marinades for hidden onion or garlic.
How to follow the diet
Work through these steps with a FODMAP-trained registered dietitian. The goal is the widest diet you can comfortably tolerate.
Step 1 · Usually 2-6 weeks
Step 2 · Commonly 6-8 weeks
Step 3 · Long term
A simple example
This sample shows the shape of a day, not prescribed portions. Adjust quantity, energy, allergies, preferences and medical needs with your dietitian.
Use garlic-infused oil, fresh herbs, chives, ginger, citrus and suitable spices instead of relying on onion and garlic.
Oats with lactose-free milk, blueberries, kiwifruit and a small spoon of maple syrup.
Rice with plain chicken or firm tofu, carrot, cucumber, green beans, herbs and garlic-infused oil.
An orange with plain rice cakes and hard cheese, or a suitable portion of peanuts.
Plain salmon, roasted potato, bok choy and aubergine with lemon and fresh herbs.
Shopping shortcut
“Gluten-free,” “natural,” or “dairy-free” does not automatically mean low FODMAP. Read the ingredient list and check the serving.
They often appear in stocks, seasoning blends, sauces, marinades and processed meats.
Sorbitol, mannitol, xylitol and maltitol are polyols and common in sugar-free gum or confectionery.
Lactose-free dairy may suit step 1. Choose calcium-fortified plant milk and confirm the source ingredients.
Several low or moderate servings can add up. Keep the first weeks simple enough to interpret.
Before you start
A food guide can help you prepare. It cannot diagnose the cause of symptoms or replace individual care.
No. The stricter first step is temporary. Reintroduction and personalisation are what turn it into a sustainable, varied long-term diet.
No. Wheat can be limited because of fructans, a FODMAP, rather than gluten. If coeliac disease is possible, speak with a clinician before removing gluten because testing is most accurate while you are still eating it.
Stop adding restrictions and review the plan with a clinician or dietitian. Digestive symptoms have many possible causes, and another approach may be more appropriate.
Seek prompt medical advice for blood in the stool, unexplained weight loss, persistent fever, severe or worsening pain, repeated vomiting, anaemia, or symptoms that wake you from sleep. Seek urgent care for severe symptoms.
The food examples are educational, but the full diet is best completed with a FODMAP-trained registered dietitian. Professional guidance reduces unnecessary restriction and helps interpret reintroduction results.
