Acorn squash
Acorn squash is a low-histamine vegetable with no known histamine-releasing or blocking properties.
Acorn squash is generally considered one of the more straightforward vegetables for histamine-sensitive people.
-
Why it's well-tolerated — it's a fresh, unprocessed vegetable with no fermentation, aging, or known histamine-releasing compounds involved
-
Freshness still matters — like most produce, the fresher the better; once cut and stored, any vegetable can start to degrade
It tends to be a reliable, easy-to-include option for low-histamine cooking.
