Green beans
Fresh green beans are low in histamine with no known histamine-releasing or DAO-blocking properties.
Green beans are a simple fresh vegetable that doesn't contain significant histamine and has no established connection to histamine release or breakdown interference.
-
Fresh or frozen works well — both fresh and plain frozen green beans stay in the low-histamine range; canned versions are still generally low, though some people with strong sensitivities prefer fresh or frozen
-
Cooking has no negative effect — steaming, roasting, or sautéing green beans doesn't change their histamine-friendly status, unlike fermented or vinegar-preserved vegetables
They're one of the more reliably easy vegetables to include across a range of meals.
