Overview
About Grape
Grapes look innocent, but a normal bunch is a real fructose load: they rate high in excess fructose and high FODMAP overall, which is why grapes cause bloating, gas or loose stools once you get past a few.
Two grapes are low FODMAP; a handful is where the fructose starts to outrun the glucose your gut can absorb. Grapes are also the base of wine and raisins, and drying only concentrates that sugar, so raisins and sultanas hit harder per bite than the fresh fruit.

How Grape scores
Watch for
What trips people up
- High in excess fructose: a couple of grapes are fine, but a full bunch delivers more fructose than glucose and can trigger bloating, wind and urgency in a sensitive gut
- Dried into raisins or sultanas the sugars concentrate, so a small scattering can outweigh a plate of fresh grapes for FODMAP purposes
- Moderate salicylates, tending higher in red and dark varieties than in pale green, so grapes can add to your salicylate load if you already react to it
- As the base of wine, grapes bring their fructose along while wine layers sulfites and histamine on top

FAQ
Common questions about Grape
Why do grapes bloat me or upset my stomach?
Grapes are high in excess fructose, meaning they carry more fructose than glucose once you eat more than a couple. The surplus fructose is poorly absorbed in the small intestine and gets fermented further down, producing gas, bloating and sometimes loose stools. A very small serving is low FODMAP; a whole bunch is not.
Are grapes low FODMAP?
Only in tiny amounts. Around two grapes sits within a low FODMAP serving, but three or more tip into excess fructose and become high FODMAP. If grapes bother you, the fix is usually portion size rather than cutting them out entirely.
Are red grapes or green grapes worse?
For gut symptoms they behave much the same, since both carry excess fructose. The difference is salicylates: red and dark grapes tend to run a little higher than pale green ones, so green grapes are the marginally safer pick if salicylates are your trigger.
