There are 39 grams of sugar in 12 ounces of Coca-Cola and 41 grams of sugar in 12 ounces of Pepsi. These numbers apply to regular drinks only.
Soft drinks are often criticized for their sugar content with some drinks containing as much as 87 grams of sugar. While the content of most regular sodas falls in the range between 28 and 45 grams of sugar, some contain no sugar and others contain more than 50 grams.
To reduce the amount of sugar in their products, some beverage makers have produced diet versions of their drinks. For example, the makers of Coca-Cola have diet versions of Coke, Sprite, and Fanta. Reduced-sugar products tend to contain some sugar, but not as much as their high-sugar counterparts do. Examples include Pepsi Next and Dr. Pepper 10. The sugar content is often replaced by artificial sweeteners, such as aspartame, to retain taste.
