A 12-ounce can of sweetened soda or cola contains 33 grams of sugar, bringing the calorie count to 136. Sugar-free sodas or diet sodas do not contain any sugar.

A 12-ounce can of sweetened soda also equates to eight teaspoons of sugar, regardless of the brand purchased. Fountain soda from fast food restaurants and convenience stores contains less sugar due to added ice cubes.

Soda and most other soft drinks have little nutritional value. Drinking a soft drink occasionally should not harm an individual's health, but does add to a person's daily calorie count. It is advised to opt for drinks made with fresh fruits, containing natural sugars, rather than colas.
