There are three main differences between Diet Coke and Coke Zero: flavor, amount of caffeine, and type of sugar replacements, according to MedicineNet.While both Diet Coke and Coke Zero do not contain sugar or calories, they each have their unique taste. Coke Zero tastes similar to the original Coca-Cola because they share the same flavor bases, while Diet Coke uses different flavors.
The amount of caffeine also differs between the two with Diet Coke containing more. According to Caffeine Content Hub, Diet Coke has 46 mg of caffeine per 12-ounce can, compared to Coke Zero's 34 mg per 12-ounce can. The latter is the same amount as Coca-Cola Classic, which has 34 mg per 12-ounce can, but the classic version also has 39 grams of sugar. To sweeten Diet Coke,The Coca-Cola Companyuses artificial sweetener aspartame. Coke Zero is also sweetened with aspartame, as well as acesulfame potassium (Ace-K).Medical News Today describes that Ace-K is often used in conjunction with other sweeteners, like aspartame, in order to give the beverage or food item a less-bitter aftertaste.
Based on the contents of Diet Coke and Coke Zero, MedicineNet contends that neither soda is a better pick for health reasons. So, ultimately it comes down to personal preference, but if you are looking to lose weight or have diabetes and want to drink soda, MedicineNet recommends to simply go with a sugar-free can of soda.
