What to know about butternut squash
Butternut squash is a sweet, gentle winter squash that most people assume is easy on the gut, but it is high FODMAP by the cupful because of the sugar alcohol mannitol. A small side of a third of a cup is usually fine, while a big roasted bowlful can tip a sensitive gut into bloating and loose stools. It is otherwise a clean, strongly anti-inflammatory vegetable with no nightshade or histamine concerns.
Watch for
- High FODMAP once the serving grows: the polyol mannitol builds up past roughly a third of a cup and can cause bloating, wind or loose stools
- Portion is everything here, so a small side is low FODMAP while a full roasted bowl is not, unlike a food that triggers at any dose
- High in lectins when raw, though thorough cooking, which squash always gets, brings that right down
