Many packaged baked goods may contain potassium bromate, a food additive linked to cancer. Multiple studies have suggested that this chemical increases the incidence of cancer in the kidneys, thyroid and other organs.

Meanwhile, here in the U.S., potassium bromate is still completely legal. The FDA hasn’t even reviewed the chemical since 1973.
