26 Apr 2019 --- Consumption of propionate, or propionic acid – a mold-preventing preservative widely used in baked goods, cheese, animal feeds and artificial flavorings – appears to increase levels of several hormones that are associated with obesity and diabetes. This is according to research by the Harvard T.H. Chan School of Public Health in collaboration with Brigham and Women’s Hospital and Sheba Medical Center in Israel. The findings have prompted the researchers to call on the US Food and Drug Administration (FDA) to further investigate the preservative and potential alternatives that could be used in food preparation. The report was published in the online journal Science Translational Medicine.
