Hemochromatosis is a genetic disorder caused by one of several mutations related to double-than-normal iron absorption, which increases susceptibility to iron overload (1). Although the disorder affects about one in 200 in the U.S., it’s still largely unrecognized and can lead to deposits in organs—such as the liver—leading to organ damage and failure if not treated early enough (2-4).
Because the disorder is most prevalent in males of Northern European ancestry, particularly Celtic (5), it was hypothesized as recently as 2007 to be a possible Neolithic adaptation (6). The Neolithic period marked an early European dietary transition from high intake of meat to cereal grains (6).
Whether or not this hypothesis is correct, the state of the disorder suggests potential dietary management through eating primarily vegetarian foods such as the one eaten during the time of these early ancestors—cereal grains, little red meat, and limited vitamin C intake. This low-iron diet to prevent to iron overload, according to the Hemochromatosis Management Working Group, can help to “decrease the frequency and severity of iron overload,” thereby preventing many of the detrimental effects of the disorder (4).
