Tiger nuts
Tiger nuts are unfermented tubers (not actually nuts) with no known histamine content or release effect.
Despite the name, tiger nuts are small tubers of the sedge plant Cyperus esculentus — and like most plain, unprocessed plant foods, they don't go through any histamine-raising process.
-
Low by nature — tiger nuts aren't fermented, aged, or heavily processed in their plain dried or raw form, which keeps histamine content low
-
Growing in popularity — tiger nut flour and tiger nut milk are becoming more common; plain versions without additives are generally considered similarly low-histamine
Tiger nuts and their derivatives are generally a comfortable choice, particularly as a nut-free alternative.
