Diet Coke and Coke Zero are popular sugar-free alternatives to regular soda, but is one healthier than the other?
The answer largely depends on your taste preferences and health goals, as both drinks share similarities with subtle differences.
Similarities Both Diet Coke and Coke Zero contain no sugar or calories and rely on artificial sweeteners, such as aspartame, to provide sweetness without the caloric impact of sugar.
They also have similar caffeine levels and are designed to appeal to those seeking low-calorie beverage options.
Differences The primary difference lies in flavor and formulation: Diet Coke has a lighter, more citrusy taste and uses a distinct blend of artificial sweeteners.
Coke Zero is formulated to taste closer to classic Coca-Cola, with a richer, more traditional cola flavor.
Nutritionally, they are nearly identical, so the choice often comes down to taste. However, both contain artificial sweeteners, which some studies suggest may affect gut health or appetite regulation in certain individuals.
