Avocado
Fruits · Other Fruits
Avocado is low FODMAP in small amounts only. An eighth of an avocado, about 30 g, is rated green, carrying 0.14 g of sorbitol. Half an avocado, about 80 g, is rated red, with sorbitol at 0.37 g. Sorbitol is the single group at issue here: no fructans, lactose, GOS or excess fructose register at either tested serve.

Breakdown for 0.13 avocados
Is avocado low FODMAP?
Avocado is a sorbitol story and nothing else. At 30 g the sorbitol comes in at 0.14 g, under the 0.2 g line where a polyol starts to count as moderate, so that serve is rated green. At 80 g, half a fruit, sorbitol reaches 0.37 g and the serve is rated red. Sorbitol is a polyol, the P in FODMAP: it is absorbed slowly and incompletely, and it draws water into the bowel, which is why polyol reactions often arrive as cramping, urgency or a sudden bloat rather than gas alone.
Avocado and IBS: what to know
Portion is the whole game, and an eighth of an avocado is smaller than most people picture: two or three thin slices, not a scooped-out half. Sorbitol tolerance varies widely, so some people sail through a quarter while others notice 30 g. Polyols also stack across a day, so avocado on toast at breakfast and button mushrooms at dinner can add up even when neither serve is large on its own. If you have already reintroduced sorbitol successfully, you have more room than the tested serves suggest.
Gut-friendly ways to eat avocado
Treat avocado as a garnish rather than a base. Two or three thin slices, near the 30 g green serve, sit well on toast with eggs, which register no FODMAP groups at all at two eggs, 100 g. For creaminess in bigger volume, lean on olive oil, tahini or feta instead of piling on more avocado. Shop-bought guacamole has its own entry in the guide, but how much you scoop is what governs your load, so serve it with a spoon rather than a bowlful of chips.
Frequently asked questions
Is avocado low FODMAP?
In small amounts, yes. An eighth of an avocado, about 30 g, is rated green with 0.14 g of sorbitol. Half an avocado, 80 g, is rated red, with sorbitol at 0.37 g. So avocado is not off the table, but a whole half spread on toast sits well past the green serve.
How much avocado can I eat on a low FODMAP diet?
Stay near 30 g, an eighth of a fruit, which is the green serve in our data. The next tested point is 80 g, half an avocado, and it is rated red. There is no amber step between the two in the data, so anything approaching half a fruit is best treated as a high FODMAP portion.
Why does avocado cause bloating?
Sorbitol. Avocado carries 0.14 g of it at 30 g and 0.37 g at 80 g, and sorbitol is a polyol that is absorbed slowly and pulls water into the bowel. That extra water, plus fermentation further down, is what produces the bloating and cramping people report after a generous serve.
Is guacamole low FODMAP?
It depends on the recipe and the scoop. Guacamole has its own entry in the guide, but shop-bought versions usually include onion or garlic, and both of those are rated red in their own right. Homemade guacamole with lime, coriander and chives, kept to about 30 g of avocado per serve, keeps you near the green rating.
