PULLMAN, Wash. – Iron is found in buildings and skyscrapers. It makes up most of the earth’s core. It’s even found in the sun and stars. And yes, it’s also in a bowl of cereal.
In nature, we might find iron in a black and steely mineral form buried deep in the earth. But right in our bodies, we also find iron in blood.
That’s what I found out from my friend Brennan Smith when we set out to investigate why there’s iron in cereal and other foods.
Smith is a professor of food science who teaches students at Washington State University and the University of Idaho. He explained that iron is in cereal and other foods for our nutrition. I wondered exactly what it does for us.
