A popular artificial sweetener that's widely found in sugar-free foods and beverages is being labeled as a possible cancer risk by the World Health Organization (WHO). WHO's cancer research agency, International Agency for Research on Cancer (IARC), determined aspartame to be a possible carcinogen after reviewing and assessing the potential carcinogenic effect of the sweetener, but says it's safe to consume in limited amounts.
Dr. Donald Hensrud, a Mayo Clinic physician specializing in nutrition and the editor of "The Mayo Clinic Diet," explains what this new classification means and why the risk is low.
"This new decision of declaring aspartame a possible carcinogen is going to add some confusion. First of all, the level of risk is low, but consuming something over many years, even in a low amount, may possibly add to the risk," says Dr. Hensrud.
