A new way to study iron bioavailability in geophagic earth

Who would have thought, but— chickens are a great model of human iron metabolism! As such, they can help us to understand effects of geophagy. In our recently published paper in Nutrients we show that a poultry model has clear advantages over prior methods used both in vitro and in humans, and represents an important step in explaining the public health impact of geophagy on iron status.
