Amaranth
An ancient seed grain that's naturally low in histamine and free from the common triggers found in many other grains.
Amaranth is a gluten-free pseudo-grain with no known histamine content and none of the fermentation or aging processes that typically raise histamine risk.
-
Not a true grain — amaranth is technically a seed, which means it sidesteps some of the concerns around certain processed grain products, and it contains no gluten
-
Whole vs. processed — plain cooked amaranth is your safest bet; flavored or packaged amaranth products may include additives or vinegars that could add histamine load
Amaranth works well as a rice or oatmeal substitute and is generally considered one of the more reliably low-histamine grain alternatives.
