What to know about zucchini
Zucchini (courgette) is a mild summer squash that stays clean on histamine, oxalates, gluten, nickel and sulfites. Its flags are moderate: a FODMAP grade of C that means it is low FODMAP only in smaller servings, moderate salicylates (C), and a high lectin grade (E) that lives mostly in the skin and seeds. In a modest portion it is one of the easier vegetables for a sensitive gut.
Watch for
- FODMAP graded C: low FODMAP in a small serving (Monash caps it around 65 g), higher if you eat a big plate
- Graded high in lectins (E), mostly in the peel and seeds, so peeling helps lectin-sensitive eaters
- Moderate salicylates (graded C), a minor flag on a strict salicylate elimination diet
