Diet sodas are carbonated beverages that are sweetened with artificial or non-nutritive sweeteners instead of sugar. These sweeteners, such as aspartame or sucralose, provide a sweet taste with fewer or no calories, making diet sodas popular among those looking to reduce their sugar intake or manage their weight. While diet sodas can be a low-calorie alternative to regular sodas, some studies suggest potential health concerns related to their long-term consumption. These concerns include possible links to metabolic issues and changes in gut bacteria. However, more research is needed to fully understand the effects of diet sodas on health.
