Diet Coke is a no-calorie carbonated soft drink produced by The Coca-Cola Company. It was first introduced in 1982 as a lower-calorie version of regular Coca-Cola.

- Calories: 0
- Total fat: 0g
- Sodium: 40mg
- Total carbs: 0g
- Sugars: 0g
- Caffeine: 46mg
Diet Coke contains no calories or sugar because it is sweetened with aspartame, an artificial sweetener. The lack of calories comes from the use of aspartame rather than high fructose corn syrup, which sweetens regular Coca-Cola.

Safety and Controversies Surrounding Aspartame
Aspartame has been extensively studied and approved for use by major regulatory agencies, including the FDA and EFSA. However, there are still some concerns and controversies surrounding its safety. Some key discussion points include:
- Aspartame metabolism and potential toxicity from its metabolites (phenylalanine, aspartic acid, methanol)
- Purported links to cancers, seizures, headaches, and other conditions
- Whether aspartame consumption leads to weight gain due to insulin spikes
- Effects on gut bacteria and inflammation
- Safety for certain populations like pregnant women and children
Beyond sweeteners, Diet Coke also contains carbonated water, caramel color, phosphoric acid, natural flavors, and caffeine. The carbonation and caffeine can affect hydration status and interact with medications. Phosphoric acid impacts acidity and tooth enamel. Artificial colors like caramel coloring have also received scrutiny over health impacts.
Health Implications and Controversies of Diet Soda Consumption
Compared to regular soft drinks, diet sodas like Coke Zero and Diet Coke have little to no calories and sugar. This may benefit diabetes control and weight management in some individuals. However, the overall beverage pattern matters more than single products. According to leading health agencies, plain water remains the optimal zero-calorie beverage for hydration.
There are also concerns that diet soda may increase cravings for sweet foods and lead to overeating. Some studies suggest artificial sweeteners like aspartame disrupt appetite signals and gut micro biota. However, findings remain inconclusive on whether diet sodas counter intuitively contribute to obesity and metabolic disease.
