Squash
Squash is naturally low in histamine with no known triggering properties — a reliable everyday vegetable.
Whether you're eating zucchini, butternut, or acorn squash, the whole family tends to be low in histamine and easy to tolerate.
-
Versatile and low-risk — squash doesn't accumulate histamine the way aged or fermented foods do, and cooking methods like roasting or steaming don't change that
-
Freshness still counts — cooked squash sitting in the fridge for several days can develop slightly more histamine, so fresher is better as a general rule
Squash is one of the more dependable vegetables to lean on when keeping histamine low.
