Best All-Natural Diet Sodas

Free of calories, fat, and sugar, Blue Sky Free considers itself to be the guilt-free soda choice. Here are some of the ingredients you should know about before picking up a six-pack.

• Truvia and Rebiana — Developed by Cargill and Coco-Cola, Truvia is derived from the stevia plant. The FDA initially banned stevia as a food additive because of some studies suggesting stevia could cause cancer. However, it was deemed safe by the FDA after undergoing a stevia refining process creating Reb-A or Rebiana. These ingredients are highly processed derivatives of stevia, so perhaps not the best choice if you are looking for whole, unrefined sweeteners.
• Natural flavors — To create the lemon lime flavor, Blue Sky extracts flavors from Californian Meyer lemon and West Indian lime.
