Fruits · Other Fruits
Yes, grapes are low FODMAP at the tested serve of 15 grapes, about 75 g, whether red or green. Keep grazing, though, and the picture changes: at 40 grapes, about 200 g, the rating shifts to amber as the fructose climbs from 0.1 g to 0.27 g. A measured handful is the way to enjoy them.

Breakdown for 15 grapes
Is grapes (red/green) low FODMAP?
Fructose is the group to watch in grapes. At the green serve of 75 g there is 0.1 g of fructose and 0.05 g of fructans, and the serve rates green. At 200 g the fructose nearly triples to 0.27 g and fructans reach 0.13 g, which moves the rating to amber, a proceed-with-caution portion rather than a stop sign. Unlike watermelon, grapes never bring mannitol or sorbitol into the mix, so the story stays a simple one about quantity.
Grapes (red/green) and IBS: what to know
Grapes are grazing food, and that is exactly the risk: a bowl on the table disappears one grape at a time, and 40 grapes is easy to reach without noticing. Counting out 15 and putting the rest away keeps you at the green serve. This entry covers red and green table grapes together, so there is no need to favour one colour over the other. If reintroduction showed excess fructose is a trigger for you, the amber 200 g serve is worth treating with extra respect, since fructose is what grows fastest between the two tested points.
Gut-friendly ways to eat grapes (red/green)
A frozen 75 g serve of grapes makes a slow, satisfying dessert that is hard to overeat. They also earn their place on a gut-friendly cheese board next to cheddar and brie, both naturally low in lactose, or halved through a chicken salad. In a fruit salad, pair 15 grapes with strawberries, whose green serve is a generous 140 g, to build volume without leaning on a bigger grape portion.
Frequently asked questions
How many grapes can I eat with IBS?
Fifteen grapes, about 75 g, is the tested green serve. At 40 grapes, about 200 g, the rating moves to amber, with fructose rising to 0.27 g. Portion out the green serve rather than eating from the bunch, because the difference between the two is easy to graze through.
Are red and green grapes both low FODMAP?
Yes. This entry covers red and green table grapes together, and the tested serves apply to both: 15 grapes at about 75 g rate green, 40 grapes at about 200 g rate amber. Pick whichever variety you prefer and let the portion, not the colour, guide you.
Are raisins low FODMAP like grapes?
Raisins are dried grapes, so the water is gone and the sugars sit much closer together, which makes their serving size a different question from fresh grapes and their 75 g green serve. They have their own entry in the guide with their own tested portions, so check that page before pouring them over muesli.
Can I eat grapes during the FODMAP elimination phase?
Yes, at the green serve of 15 grapes, about 75 g. With only 0.1 g of fructose and 0.05 g of fructans at that portion, grapes are a practical elimination-phase fruit. Save the larger 200 g amber portion for after elimination, once you know how you handle fructose.
