E196: Why do we need zero calorie sweeteners, and are they safe?

Artificial sweeteners, known more recently as non-nutritive or low-calorie sweeteners, have been a source of great hope. What could be better than enjoying sweetness in foods but without the calories? Sucralose, xylitol, stevia, saccharin, aspartame, there are a lot of them out there. You may add them to food yourself, you may consume them in beverages, and if not, there’s a good chance they’ll show up in foods that you buy. But, do they work and are they safe? Few know this area like Dr. Richard Mattes, distinguished Professor of Nutrition Science at Purdue University.
