What is the most popular sugar substitute in America?

The most commonly used sugar substitutes in products like soft drinks are chemicals such as Aspartame and saccharin. Honey has been used as a natural sweetener since ancient times and it is still very popular with people who wish to avoid the side effects that come from artificial sweeteners. There is a plant called Stevia which is increasing in popularity because it is both natural and much sweeter than sugar, and so it can be used in tiny amounts to great effect.
