Absorption of Iron Naturally Present in Soy.

ABSTRACT: Plant-based foods can offer sustainable and healthy dietary choices. Soybeans and derivatives (for example, flour, concentrate, or isolate) are the primary protein source for plant-based products, including meat analogs, and are naturally rich in iron. To investigate the nutritional contribution of iron naturally present in soy, this narrative review presents iron bioavailability data from isotope studies in humans aged >3 y. To allow interstudy comparison, we adjusted mean iron absorption for iron status (that is, serum ferritin of 15 μg/L), quantified native iron absorbed, and compared with daily human requirements for absorbed iron where possible. Adjusted iron absorption from soybeans served as part of meals varied widely (4.1%-22.2%), translating to contributions of 13%-70% and 10%-40
