What it is: An all-natural, no-calorie sweetener derived from the leaf of the stevia plant.
Also goes by: Reb A, rebiana, Truvia, PureVia, Enliten, and Sun Crystals.
Where you’ll find it: In protein-shake mixes and soft drinks; it’s also sold alone as a diet sweetener.
Good to know: You can bake with stevia, but it does best with medium temperatures. While the U.S. Food and Drug Administration generally recognizes this group of sweeteners as safe, use stevia moderately, says Jennifer Nelson, director of clinical dietetics at the Mayo Clinic in Rochester, Minnesota.
