                                According to the National Institutes of Health (NIH), a significant portion of the global population suffers from iron deficiency, yet the answer to whether humans can digest iron oxide is a firm 'no'. Unlike the bioavailable forms of iron found in food, the chemical compound known as rust is a form of iron our digestive system cannot readily process.
