Do diet sodas have less caffeine?

Not necessarily. The caffeine content of diet sodas can vary widely depending on the brand and the type of soda. Some diet sodas contain around the same amount of caffeine as regular sodas, while others contain less. For example, according to the Center for Science in the Public Interest, a 12-ounce can of Coca-Cola contains 34 milligrams of caffeine, while a 12-ounce can of Diet Coke contains 46 milligrams of caffeine. However, some diet sodas, such as Diet Pepsi, contain less caffeine than regular sodas, with a 12-ounce can containing only 35 milligrams of caffeine. Therefore, it is important to check the nutrition facts label of a diet soda to determine its caffeine content.
