Artificial sweeteners, which are also called "non-nutritive sweeteners," add sweetness to many foods and beverages without adding any calories or nutrition. They are well-known ingredients in diet sodas and snacks, and some are easily identified in little colorful packets alongside sugar in your favorite coffee shop or restaurant.
