The purpose

The diet helps you identify foods that may be contributing to IBS symptoms.

The process

It usually involves restriction, reintroduction, then personalisation.

The warning

It is best followed with support from a doctor or registered dietitian.

The low FODMAP diet can be one of the most useful tools for people with IBS, but it can also feel confusing when you are just starting out.

You may wonder what you can eat, what you should avoid, how strict you need to be, and whether the diet is meant to last forever. The good news is that the low FODMAP diet is not meant to remove foods permanently. It is a structured way to understand your body.

You can use Fodmap Scanner on Google Play to scan ingredients, search foods, save history, log meals, and track symptoms as you go.

Quick takeaway

The low FODMAP diet is usually a short-term structured process. You reduce high FODMAP foods, reintroduce them carefully, then build a personalised diet based on what your body tolerates.

What is the low FODMAP diet?

FODMAPs are certain carbohydrates that can be difficult for some people to absorb. In people with IBS, they may contribute to bloating, gas, stomach pain, diarrhoea, constipation, or general digestive discomfort.

The low FODMAP diet reduces foods that are high in these carbohydrates for a period of time, then reintroduces them to help identify personal triggers.

Low FODMAP foods beginners often start with

Everyone is different, but many people begin with simpler foods that are generally considered lower FODMAP in suitable portions.

  • Rice, oats, quinoa, and potatoes
  • Eggs, plain meat, fish, and tofu
  • Carrots, courgette, cucumber, lettuce, and spinach
  • Firm bananas, oranges, strawberries, and blueberries
  • Lactose-free milk or suitable dairy alternatives
  • Plain herbs, salt, pepper, and garlic-infused oil

Portion size still matters, so it is important to check foods properly and not assume every low FODMAP food is unlimited.

High FODMAP foods beginners may need to avoid at first

During the early restriction phase, some foods are commonly reduced because they may be higher in FODMAPs.

  • Garlic and onion
  • Wheat-based bread, pasta, and cereals
  • Apples, pears, mango, and watermelon
  • Milk, soft cheese, and some yoghurts
  • Beans, lentils, and chickpeas
  • Cauliflower, mushrooms, and asparagus
  • Honey and some sweeteners ending in “ol”

Do not rely on memory alone

The easiest way to start is to check foods before eating, save what works, and track symptoms so you can see patterns clearly.

The 3 phases of the low FODMAP diet

1. Restriction

This is where high FODMAP foods are reduced for a short period. The aim is to see whether symptoms improve.

2. Reintroduction

Foods are reintroduced carefully, usually one group at a time, so you can test your tolerance.

3. Personalisation

The long-term goal is to build a diet that gives you as much variety as possible while reducing symptoms.

Common beginner mistakes

  • Staying in the restriction phase for too long
  • Not tracking symptoms
  • Forgetting sauces, snacks, and drinks
  • Ignoring portion sizes
  • Assuming gluten-free always means low FODMAP
  • Not getting professional support when needed
