> his claim: food dyes cause cancer, and a.d.h.d. in children. > what the research suggests: while some small clinical trials have suggested that certain synthetic food dyes may increase hyperactivity in children, there is no solid evidence that they directly cause a.d.h.d. > in 1990, the food and drug administration banned the use of red dye no. 3 in cosmetics after research in animals linked it to cancer. at the time, the agency said that it would also work to extend the ban to foods and drugs, but it has not yet done so. so it causes hyperactivity and cancer?
