How do you verify that a soft-drink contains diet soda rather than soda sweetened with fructose?

To verify whether a soft drink contains Diet Soda instead of fructose-sweetened soda, you can check the ingredient list on the label for artificial sweeteners like Aspartame, sucralose, or stevia, which are commonly used in diet sodas. Additionally, you can look for the term "diet" in the product name, as this usually indicates the absence of sugar. For more precise analysis, laboratory testing can be conducted to measure the levels of sugars versus artificial sweeteners.
