Yam
Yam is a starchy, low-histamine root vegetable with no well-established link to histamine release or DAO blocking.
Yam is a dense, starchy root that sits comfortably in the low-histamine category.
-
Naturally low histamine — fresh yam doesn't contain significant histamine and isn't known to prompt the body to release its own stored histamine
-
Different from sweet potato — yam and sweet potato are often confused, but both share a similarly low-histamine profile in their plain, cooked forms
Either boiled, baked, or mashed, yam tends to be a reliably gentle choice.
