Key Differences and Similarities
These products are essentially the same, especially regarding their main selling point: not containing sugar.
The main difference lies in the type of sweetener used and the caffeine content. Diet Coke uses aspartame as its primary sweetener, while Coke Zero uses both aspartame and acesulfame potassium (Ace-K). Acesulfame potassium is another calorie-free sweetener that the body does not metabolize, thus not raising blood sugar levels.
Coke Zero has less caffeine (34 mg) than Diet Coke (46 mg). However, both beverages contain caffeine levels well below the USDA's recommended daily limit of 400 mg for adults.
One debatable difference is the taste of these two drinks. The company doesn’t go into detail about how it has changed but maintains that it “has more real Coca-Cola flavor, still without any sugar”. Coke Zero has a slightly different aftertaste than Diet Coke, likely due to its acesulfame potassium. Diet Coke tastes more like regular Coke to many people. However, for some, it’s the reverse. Neither tastes just like the original Coca-Cola. Depending on multiple factors - like whether you get it from a beverage fountain, in a can, or in a bottle - each type may have a slightly different taste.
Potential Health Effects
For most, not many harmful side effects come from drinking carbonated beverages in moderation. However, caffeine and artificial sweeteners may negatively affect some people, even at moderate intake levels.

Caffeine
The United States Department of Agriculture (USDA) recommends that adults have no more than 400 mg of caffeine per day. That’s about 4 cups of coffee, or nine or eleven 12-ounce (355-mL) cans of Diet Coke or Coke Zero, respectively. So, you’re unlikely to exceed the limit by drinking these sodas in moderation. If you’re highly sensitive to caffeine, though, you may want to watch your intake of these beverages. Otherwise, they contain a relatively low amount of caffeine.
Artificial Sweeteners
Aspartame may cause headaches for some people, according to the American Migraine Foundation. While this effect may vary, it’s good to know ahead of time so you can connect the dots if you start experiencing headaches after drinking these beverages. In addition, some research has indicated that aspartame may be carcinogenic. More long-term, high quality human studies are necessary before we can connect aspartame to cancer.A concluded that products containing aspartame are safe to consume by the general population at current levels. However, it may pose certain health risks for certain populations, such as:people with seizures, neurological conditions, people with phenylketonuria, people who are pregnant. Those who take a more cautious approach to ingredients in foods may want to avoid aspartame, and that’s OK. However, it’s worth noting that the Food and Drug Administration (FDA) considers aspartame safe.
Similar to aspartame, acesulfame potassium has been evaluated for potential carcinogenic effects. Again, however, the evidence is unclear, and more long-term, high quality human studies are necessary.
Alternatives to Diet Soda
With the conflicting evidence surrounding artificial sweeteners, you may be wondering how you can get your fizzy fix while limiting your artificial sweetener intake. Here are some ideas you can try:
- Flavored waters: Calorie-free flavored waters can be refreshing and hydrating. Consider them as a healthy addition to your fridge or cooler.
- Kombucha: Kombucha is a probiotic-filled beverage that promotes healthy gut bacteria and is naturally fizzy due to the fermentation process. Most kombuchas have less sugar than regular sodas, but compare labels to ensure you’re not overdoing it on added sugars.
- Probiotic sodas: Some brands of probiotic “soda” are similar to kombucha. They’re designed to taste similar to soda but have far less sugar. Their benefits are similar to those of kombucha due to the probiotics.
- Stevia sodas: Several brands of fizzy drinks mimic popular soda flavors and contain no artificial sweeteners. Instead, these sodas use plant-based alternative sweeteners like stevia or monk fruit. They still taste similar to soda but have no sugar or artificial sweeteners.
- Sparkling water: If it’s fizz you’re after rather than the sweetness, sparkling waters may come to your rescue. While they’re not always sweet, they still provide carbonation without any sugar or artificial sweeteners.
