Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Buckwheat (Fagopyrum esculentum) has traditionally been used in some cultures as a food to support blood health, including in the context of anemia. The rationale for its use is primarily nutritional: buckwheat is a source of non-heme (plant-based) iron and contains other nutrients that support hematopoiesis, such as folate, copper, and certain B vitamins. Traditional applications are particularly noted in Eastern European and Asian folk medicine, where buckwheat porridge or flour is recommended as a nourishing food for those recovering from illness or weakness, including forms of anemia.

However, scientific validation for buckwheat as a treatment or significant support for anemia is limited. While buckwheat does contain iron, its non-heme form is less bioavailable than the heme iron found in animal products. Additionally, buckwheat contains phytic acid, which can inhibit iron absorption. Some laboratory studies suggest that certain compounds in buckwheat might enhance iron uptake, but robust clinical evidence in humans is lacking. Thus, buckwheat may contribute to overall dietary iron intake as part of a balanced diet, but it is not a substitute for iron supplementation or medical treatment in cases of clinical anemia.

In summary, the use of buckwheat for anemia is rooted mainly in traditional dietary practices rather than strong scientific evidence.
