Quick Answer: Is Avocado Low FODMAP?
Only in very small servings. Monash University rates avocado green at 30g (about 2 tablespoons / one-eighth of a medium fruit). Anything above that becomes high FODMAP due to sorbitol — a polyol that ferments in the gut and triggers IBS symptoms.
Evidence-Based: Avocado is one of the most misunderstood "healthy" foods on the low FODMAP diet. Sorbitol content rises sharply past 30g.
Portion Chart
| Amount | FODMAP Status |
|---|---|
| 2 tbsp (30g) | ✅ Green |
| 1/4 avocado (60g) | ⚠️ Amber |
| 1/2 avocado (120g) | ❌ Red — high sorbitol |

| Guacamole (¼ cup) | ⚠️ Depends on portion + no garlic/onion |
Why Sorbitol Matters
Sorbitol is a sugar alcohol (polyol) that draws water into the intestine and ferments quickly. For IBS-D sufferers, even small extra amounts of avocado can trigger urgent symptoms within 2–4 hours. Learn more from NIDDK's IBS overview.
