low fodmap chocolate mousse

People very often ask me what the low FODMAP- diet is.

In this blog-post I will try to explain it in an easy way, so that ordinary people can understand, at least the main-points.

First I have to stress that I am not a doctor or dietitian. This is why I don’t want to go into details when I explain the diet, but instead I want to point you in the right direction with links to dietitians you can trust.

The origin of the low FODMAP-diet

The low FODMAP-diet was developed by a research-team with dietitians from the Monash University in Australia as long as 15-20 years ago. The researchers there found that many IBS-patients malabsorbs a certain short-chained carbohydrates – FODMAP.

What does FODMAP stand for?

FODMAP is an a acronym for these hard-to-digest carbohydrates and stands for:



  • Fructo-oligosaccharides (FOS) found in wheat, rye, onions and garlic
  • Galacto-oligosaccharides (GOS) found in legumes like peas, beans and


Disaccarides: Lactose found in milkproducts

Monosaccharides: Fructose mostly found in fruite


Polyos: Sugar-alchohols found in artificial sweetener that have the last two letters -ol, like sorbitol, mannitol etc…

In short: FODMAP = a certain hard-to-digest carbohydrates.

High and low FODMAP

Monash University tests food for FODMAP-content and list it in their own mobile application. I will highly recommend to buy the application AND to read about the diet at Monash Universitys website about the low FODMAP application. This is the best information you can get and directly from the research team. I really don’t want to try to explain this with my bad English when it’s written very well by dietitians!

With that said, I will write and discuss more about the different phases: Elimination, reintroduction and the outcome: your personal low FODMAP-diet + how to read labels etc… etc… in coming blog-posts. However this is NOT medical advices and has to be treated as practical advices from a patient to patient. I highly recommend to see a doctor and a registered dietitian (klinisk ern√¶ringsfysiolog in Norway) as the first help, then get advices and recipes on the internet.

Who can get help from the low FODMAP-diet?

The diet was developed for people with IBS (I will explain the term later). The researchers found that as many as 65-70% of IBS-patients would get a relief from their symptoms if they followed a low FODMAP-diet, or a FODMAP-reduced diet. This is extremely good and other researchers from universities worldwide, have gotten good results too. The diet is now one of the first treatments for IBS at many hospitals.
