The Low FODMAP Diet is a type of elimination diet that was first developed by researchers from Monash University in Melbourne, Australia. It is designed to help people suffering from irritable bowel syndrome (IBS) and research has shown that over 70% of people with IBS who follow the diet see an improvement in their symptoms, hurrah!
IBS affects around 1 in 7 people globally and can have a huge impact on every day life, mentally and physically. I was 14 when I was diagnosed (something every teenager wishes for!) and spent many years struggling to work out what triggered my symptoms. Then the Low-FODMAP Diet came along, and started changing things in a very big way.
What actually are FODMAPs?
FODMAPs are a group of carbohydrates (sugars) found in lots of different foods which are poorly absorbed in the small intestine. They can trigger symptoms such as stomach pain, gas, bloating, diarrhoea and constipation in those of us with IBS. Lovely.
What does FODMAP mean?
FODMAP is an acronym that stands for:
‘Fermentable’ refers to the way in which FODMAP sugars are broken down by gut bacteria, while ‘Oligosaccharides’, ‘Disaccharides’, ‘Monosaccharides’ and ‘Polyols’ are the scientific names given to the groups of sugars. I know — catchy huh? FODMAP is an easier way of referring to everything altogether.
What foods are FODMAPs found in?
FODMAPs are found in lots of different foods and food additives, including apples, pears, cauliflower, beans, avocado, mushrooms, asparagus, cashews, onions, garlic and milk, as well as foods made from wheat, such as pasta, bread and biscuits. FODMAPs aren’t found in proteins or fats — so foods like fish, chicken, meat, eggs and oil are all low FODMAP.
The Monash University FODMAP App (by the founders of the diet) is brilliant and something that I recommend to everybody when starting. It’s this data and information that I follow to create the low FODMAP recipes on this blog. The app uses a traffic light system to show you FODMAP levels in foods — it might be that although a food is high FODMAP in a large portion size, it’s actually low FODMAP in a smaller portion size.
How does the diet work?
There are three stages to the Low-FODMAP Diet and it’s recommended that you chat and work with your GP or a dietician, to make sure you’re following it correctly. They can make sure you’re not restricting your diet unnecessarily and it’s important too that they have the chance to rule out any other medical conditions that might be causing your symptoms.
What you have to remember is that this diet is not about being incredibly restrictive longterm. The ultimate goal is to eat and live as freely as possible with the least restrictions you can get away with — the more FODMAPs you can return to your diet without triggering symptoms, the healthier your gut is likely to be. FYI down the line it might be that your tolerance to different foods improves and you can re-introduce those that you couldn’t tolerate before – looking after your gut health is an ongoing journey!
