Dr. David Ma, a nutrition researcher at the College of Biological Science, lent his thoughts to CBC Radio’s White Coat, Black Art on a recent study that indicates artificial sweeteners may cause long-term health effects.  

“I would say that, you know, the sky is not going to fall down because we have artificial sweeteners in our diet. But certainly, we need to have an eye out for everything in our diet, including artificial sweeteners in terms of the short-term and the longer-term effects,” he said. 

Ma is professor in the Department of Human Health and Nutritional Studies and the director of the Guelph Family Health Study. He researches childhood obesity and fatty acids.
