1950s: Soy used in animal feedAbout 80% of the soy currently produced in the United States is used as animal feed, Kucuk said. In the decades to come, soy studies would shift away from soy's role in farm animal diets and toward its role in human diets. Yet she added that while natural soy food products offer health benefits, processed soy foods provide a different story. In his editorial, Kucuk noted that most Americans don't consume appreciable levels of soy foods, even though the US is the top soy producer in the world, producing about 40% of the global soy supply. "So far, we know that soy foods are good, soy foods are safe, soy foods prevent breast cancer, and also improve treatment results and decrease mortality in breast cancer patients."
