In summer there is always lots of beautiful fresh fruit begging us to eat it. However, not all fruits are our friends, as some have high levels of FODMAPs! I used to love sinking my teeth into a big juicy slice of watermelon…. But I could never work out why I ended up with a gut ache afterwards. Turns out watermelon contain high levels of oligosaccharides (fructans), fructose, and polyols, which means it is definitely a fruit to avoid while on the low FODMAP diet. Never fear though there are still lots of low FODMAP fruit you can enjoy this summer.
How much low FODMAP fruit can you have in one sitting?
Before you gorge yourself on huge amounts of ‘suitable’ fruit you need to remember that all fruit contains fructose, so limit the amount you eat in one go. According, to Dr. Sue Shepherd (one of the initial researchers of the low FODMAP diet) you should not eat more than one serve of ‘suitable’ fruits per meal or sitting (4). One serve normally equals about one metric cup of cut up fruit, or one whole piece of fruit, such as one medium banana or medium orange. You can enjoy as many serves of fruit per day as you like – but leave two to three hours between each serve (4).

Plums are high FODMAP so you need to avoid them in the first phase of the low FODMAP diet. You can try reintroducing them after you have finished testing your tolerance to the different FODMAP groups.

March 1, 2019 at 2:37 amShould one have a food allergy test before embarking on the Fodmap diet?
Alana Scott says
March 6, 2019 at 7:44 pmHi Anne,
Food allergy testing doesn’t accurately pick up food intolerances like FODMAPs. This means unless your doctor suspects you have an allergy, you are better off working with a dietitian to identify food triggers. I hope that helps!

March 4, 2019 at 3:51 amAre huckleberries low FODMAP?
Alana Scott says
March 6, 2019 at 7:42 pmHi Angela,
Huckleberries are untested. This means once your symptoms are settled you will need to test your tolerance to them by trying a small serve and seeing how your body reacts.

June 3, 2019 at 9:00 pmHi Carol,
Marionberries are currently untested. This means once your symptoms are settled you will need to test your tolerance levels to a small amount and see how you go.

Can you tell me if red currants are low Fodmap? Something has caused a flare up and I’m wondering if it’s them
Alana Scott says
July 6, 2020 at 12:45 amHi David,
Thanks for commenting. Okay so red currants haven’t been tested for FODMAPs yet – this means we don’t know if they are high FODMAP or low FODMAP so it’s possible they might have contributed towards your symptoms. Depending on what stage of the low FODMAP diet you are in, you could let your symptoms settled and then do a controlled test. This food challenge will show you if the currants caused your issues: https://alittlebityummy.com/can-i-eat-this-testing-your-fodmap-tolerance-to-untested-foods/

That is a great question. Red currents are currently untested for FODMAPs. That means we suggest you try a small serve and see how you tolerate them.
