What is the low-FODMAP diet?


Just what is the Low FODMAP diet?

Welcome! If you’re reading this it’s likely that you’ve recently been diagnosed with IBS, and your GP has mentioned this diet. Perhaps you’ve been a print out of the high and low FODMAP food list, and been told to have a Google. Well, hopefully this beginners guide to the FODMAP diet will help ease you along.

So, what is it?

FODMAP stands for “Fermentable, Oligo-, Di-, Mono-saccharides And Polyols" …which we can all agree is a giant mouthful. Essentially they’re types of carbohydrates/sugars that our bodies can sometimes find difficult to break down, and they can be found in unexpected places.

Ever wonder why you’re eating pretty ‘healthy’ (lots of veggies, legumes, cauliflower everything!) but still getting stomach aches, bloating, painful wind and other digestive distress?

It could be because those things are all high in FODMAPs and eating them in large quantities can have you running for the loo at inopportune times. The Low-FODMAP diet is intended to be a short-term exclusion diet with a reintroduction phase, which allows you to figure out what foods (if any) are triggers for your IBS symptoms. It was created by excellent people at the Monash University in Australia.

What is not?

As far as I’m aware – and again, please check this with a medical expert – it’s not meant to be a long-term diet, but rather a phase which allows you to personalize your diet and find your specific food triggers.

How could the Low-FODMAP diet help me?

Many IBS sufferers who go through the Low-FODMAP diet report a reduction in symptoms (such as bloating, excessive wind/gas, stomach aches, constipation/diarrheoa etc), and for some it can get rid of them altogether. Hopefully, by the end of the diet, you would know exactly which foods to avoid completely, which you can eat in moderation, and which are completely fine for you.

Everyone’s digestion is different, and this is why going through a diet like this can be incredibly helpful in tailoring your knowledge of exactly what your gut likes and dislikes. Better understanding these things about yourself can help you go through life pain-free and happy!

How do I do it?

The Low-FODMAP diet consists of an exclusion phase, where you eat entirely low-FODMAP to see if this reduces the severity of your symptoms. I believe this can last anywhere from two weeks to a month and a half. The next phase is reintroduction of High FODMAP foods. This should be done systematically, and one at a time, so that you can easily pinpoint a trigger food if symptoms start flaring again. I would heartily recommend working with a dietitian to ensure you go through the diet properly, and are reintroducing foods in the right quantities and at the right times for you. If dietitians are in short supply where you live, I have linked to an online course below with a registered dietitian, who will take you through the process.
