Is avocado low FODMAP?
A classic trap on this diet
Avocado is one of the most recommended "healthy fat" foods in general nutrition advice, which is exactly why it catches people out here. FODMAP status is unrelated to how nutritious a food is — it's specifically about six types of fermentable carbohydrate, and avocado happens to be high in one of them: sorbitol, a polyol.
How much is actually low FODMAP
Monash University's testing puts the low FODMAP threshold for avocado at around one-eighth of a whole fruit — a couple of thin slices, not the half-or-more serve most people would put on toast or in a salad. A typical serving size (a quarter avocado upward) moves into high FODMAP territory.
Where avocado shows up without you noticing
- Guacamole and avocado dips — easy to eat more than the low FODMAP threshold in one sitting
- "Smashed avo" on toast — a cafe-standard serve is well above an eighth of a fruit
- Poke bowls and sushi rolls with avocado as a main component

Frequently asked questions
Is avocado low FODMAP in any amount?
Only a small amount — Monash rates roughly an eighth of an avocado as low FODMAP. A typical serve most people eat (a quarter to a whole avocado on toast, in a salad, or in guacamole) is high FODMAP due to sorbitol.
Why does avocado surprise people on a low FODMAP diet?
Avocado is widely marketed as a health food, so people assume it's automatically diet-friendly. FODMAP status has nothing to do with general nutrition — it's specifically about carbohydrate types that ferment in the gut, and avocado happens to be high in one of them (sorbitol) regardless of how healthy it otherwise is.
What can I use instead of avocado?
Small amounts of avocado (an eighth or so) can often still fit; beyond that, options like hummus made without garlic (see our hummus guide), or simply oil-based dressings, are common low FODMAP swaps for the creaminess avocado provides.
