Hi Barbara, it’s based on all the research undetaken at Monash University in Melbourne, Australia. It is the scientists and dietitians there that discovered the existence of FODMAPs, and created a diet that would be suitable for IBS sufferers. It all comes from them. Please research Monash University FODMAP diet.

This list has been compiled using data from the Monash University low FODMAP diet phone application. Monash University are the founders of the low FODMAP diet. You will find may conflicting lists of allowed foods on the internet regarding the low FODMAP diet. Often it’s because research is ongoing and so food lists often become outdated. This one is up-to-date and reliable.

He didn’t make up the list but I think that it was generated from people that have had digestive problems and what did and didn’t work for the majority. Not all of the foods that are ‘bad’ are ‘bad’ for everyone. And the same thing goes for good foods. It is a great roadmap.
