Low FODMAP Diet for IBS

What is the low FODMAP diet?

The low FODMAP diet is a fairy new approach used in the treatment of IBS. FODMAP stands for ‘Fermentable Oligo-saccharides, Di-saccharides, Mono-saccharides And Polyols’. Research has shown that the low FODMAP diet can significantly reduce gut symptoms associated with IBS in over 70% of people who try it, when supported by a Dietitian experienced in this approach. It is a 6-week elimination programme, followed by a series of food challenges (reintroductions) to see which foods are causing the symptoms. Before new foods are always being tested for their FODMAP content and Dietitians will keep up to date with the changes as research develops in this area, it’s important to see a Dietitian rather than ‘go it alone’. There is also a lot of conflicting information online about this diet, and it’s easy to get confused.

Doing the diet properly will give you the best results.



Symptoms of IBS (irritable bowel syndrome) are very varied and affect people in different ways from annoying niggles to daily pain and severe bloating, and anywhere in between. If you have IBS, the low FODMAP diet may be the approach for you

Food Intolerance

Symptoms of food intolerance can be very diverse, and may involve the skin, gut and breathing. The best way to test food intolerances is to follow an elimination diet with the support of a Dietitian. Don’t be tempted to take a ‘test’ for food intolerance, as the results are unreliable and not based on sound scientific evidence.

Food Allergy

Food allergy symptoms are caused by the immune system’s reaction to food. Specific IgE antibodies are produced by the immune system in response to certain foods that are seen as ‘foreign’ and needing ‘fighting off’. As a result, histamine and other chemicals are released, causing inflammation. Only skin prick tests can confirm food allergy. A dietitian can help you manage your allergy(s) and achieve a healthy balanced diet.



Because food intolerances do not involve the immune system, you cannot test them in the same way as food allergies. Whilst many people choose to pay for expensive food intolerance tests, companies offering intolerance testing involving blood tests for IgG, DNA, hair analysis, magnetics, kinesiology, are unreliable and have no sound evidence base to back their claims. They will often give you a long list of things to avoid, and provide no information about how to consume a healthy balanced diet whilst avoiding many of your staple foods. The only reliable way to test food intolerance is to try an elimination and reintroduction programme to see if symptoms disappear then reappear when you reintroduce them. Allergy UK has some excellent information about allergy and intolerance testing.
