Understanding the Zero-Calorie Label
By FDA standards, products with less than 5 calories per serving can be labeled as zero-calorie. This means that while diet soda is marketed as calorie-free, it technically contains trace calories.
The Ingredients Behind the Label
Most diet sodas use artificial sweeteners to keep the calorie count low. Sweeteners like aspartame or sucralose contain few calories, but enough that they must be counted in the overall caloric total.
Conclusion
While diet soda’s calories are minimal, they aren’t nonexistent. Always be aware of what’s in your beverage, especially if consumed frequently.
