 What's the Difference Between Coke Zero and Diet Coke?

You've probably heard that limiting added sugar in your diet is beneficial to your health. To cut down on added sugar, people who drink soda on a regular basis should try switching to sodas made with artificial or non-nutritive sweeteners.

These substitutes give products a sweet taste without the blood sugar spikes that traditional sugar can cause. Diet drinks are a way to avoid added sugars in beverages, but sodas with the word "zero" in the name have recently entered the market. Coca-Cola is a well-known example of a brand that offers both “diet” and “zero” options. Read on to learn about the differences between Coke Zero and Diet Coke, as well as how to decide which is the better option for you.


Coke Zero and Diet Coke nutrition facts and ingredients

Ingredients and nutritional information for Coke Zero and Diet Coke are listed below. In this section, we'll go over some of the key differences and similarities that you should be aware of.

Nutritional information for Coke Zero

Ingredients in Coke Zero include:

  • caramel color carbonated water
  • acid phosphoric
  • aspartame
  • benzoate potassium (to protect taste)
  • flavors that come from nature
  • citrate of potassium
  • acesulfame potassium \scaffeine


People with phenylketonuria (PKU) should avoid it because it contains the amino acid phenylalanine.

Coke Zero has no added sugars because artificial sweeteners are used instead. Cherry, cherry vanilla, orange vanilla, and vanilla are among the flavors available. Coke Zero, which is caffeine-free, is also available.


Diet Coke nutritional information

Diet Coke contains the following ingredients:

  • caramel color carbonated water
  • phosphoric acid aspartame
  • benzoate potassium (to protect taste)
  • flavors that come from nature
  • caffeine and citric acid

Diet Coke, like Coke Zero, contains the amino acid phenylalanine, which should be avoided by people with PKU.

Diet Coke contains the following ingredients in a 12-ounce (355-mL) serving:

  • 0 calories
  • 0 grams of total fat
  • 40 mg sodium
  • 0 grams of total carbohydrate
  • 0 grams of total sugars
  • 0 gram protein
  • Caffeine content: 46 mg

Diet Coke has no added sugars because artificial sweeteners are used instead. Regular Diet Coke contains aspartame, but you can also get Splenda, a brand of sucralose, in a variety of flavors.

Diet Coke comes in a variety of flavors, including ginger lime and feisty cherry. Diet Coke, like Coke Zero, is available in a caffeine-free version.


Coke Zero and Diet Coke have a few key differences.

These products are nearly identical, especially in terms of their main selling point: the absence of sugar. The type of sweetener they contain, as well as the amount of caffeine they contain, are the only differences between the two, though these two differences are unlikely to be significant to most people.

While Diet Coke contains only aspartame, Coke Zero contains both aspartame and acesulfame potassium, also known as "Ace K" or "acesulfame K." Another calorie-free sweetener that passes through the body without raising blood sugar levels is acesulfame potassium.

Diet Coke's primary sweetener is aspartame, according to the ingredient label, and since ingredients are listed in weight order, it's reasonable to assume that it contains far less acesulfame potassium. This means that the ingredients in these drinks are very similar.

The caffeine content is also a significant difference. Diet Coke contains less caffeine than Coke Zero. Both beverages, however, are well below the recommended daily caffeine limit for adults of 400 mg The taste of these two drinks is a point of contention. Some claim they can't tell the difference, while others swear Diet Coke or Coke Zero taste the most like the "real thing."


Similarities in flavor

Coca-Cola recently announced on its website and in recent marketing materials that it has developed a new Coke Zero recipe. The company does not elaborate on how it has changed, but claims that it now "has more real Coca-Cola flavor, still without any sugar" (3).

Because of the acesulfame potassium, Coke Zero has a slightly different aftertaste than Diet Coke. For many people, Diet Coke tastes more like regular Coke. However, for some, the situation is the polar opposite.

Neither of these drinks tastes exactly like the original Coca-Cola. Each type may have a slightly different taste depending on a variety of factors, such as whether you get it from a beverage fountain, in a can, or in a bottle.


Side effects that could occur

Drinking carbonated beverages in moderation has few negative side effects for most people.

Caffeine and artificial sweeteners, on the other hand, may have a negative impact on some people, even when consumed in moderation. Adults should consume no more than 400 mg of caffeine per day, according to the United States Department of Agriculture (USDA).

That's about four cups of coffee, or nine or eleven 12-ounce (355-mL) Diet Coke or Coke Zero cans, depending on your preference. So, if you drink these sodas in moderation, you're unlikely to go over the limit. If you're caffeine-sensitive, however, you should limit your intake of these beverages. Aside from that, they contain a small amount of caffeine.

According to the American Migraine Foundation, aspartame can cause headaches in some people. While this effect may vary, knowing ahead of time will help you connect the dots if you start getting headaches after drinking these drinks.

Furthermore, some studies have suggested that aspartame may cause cancer, but other evidence contradicts this. Before we can link aspartame to cancer, we need more long-term, high-quality human studies. Those who are more cautious about food ingredients may want to avoid aspartame, which is fine. It's worth noting, however, that the Food and Drug Administration (FDA) regards aspartame as safe.

Acesulfame potassium, like aspartame, has been studied for possible carcinogenic effects in both older and more recent studies. The evidence, once again, is ambiguous, and more long-term, high-quality human studies are required .

Acesulfame potassium has also been approved by the FDA.


Which option is preferable?

Between Diet Coke and Coke Zero, there are very few differences. As a result, there is no compelling evidence to suggest that one is superior to the other. There are no significant differences in terms of nutrition. Both contain the same ingredients and have the same caffeine content, so neither is healthier than the other.

Remember that diet soda is not a healthy beverage. It's a tasty treat that can be enjoyed in moderation, and switching from regular to diet sodas is a good place to start if you're trying to cut back on sugar.


Reduce your intake of diet soda with these helpful hints.

You might be wondering how to get your fizzy fix while limiting your artificial sweetener intake, given the conflicting evidence surrounding artificial sweeteners.

Here are some suggestions to get you started:

  • Waters with different flavors. Flavored waters with no calories can be refreshing and hydrating. Consider putting them in your fridge or cooler as a healthy addition.
  • Kombucha. Because of the fermentation process, this probiotic-rich beverage promotes healthy gut bacteria and is naturally fizzy. Most kombuchas have less sugar than regular sodas, but check the labels to make sure you're not getting too much.
  • Sodas with probiotics. Some probiotic "soda" brands are similar to kombucha. They're meant to taste like soda but contain far less sugar. Because of the probiotics, they have similar benefits to kombucha.
  • Sodas made with stevia. Several brands of carbonated beverages have flavors that are similar to popular soda flavors but don't contain any artificial sweeteners. Instead, plant-based sweeteners like stevia or monk fruit are used in these sodas. They have a soda-like flavor but contain no sugar or artificial sweeteners.
  • Water that sparkles. If you're looking for fizz rather than sweetness, sparkling waters may be the answer. They provide carbonation without sugar or artificial sweeteners, even if they aren't always sweet.

Last Word

Sodas made with artificial sweeteners, such as Diet Coke and Coke Zero, may appear to be a good choice if you want to limit added sugars.

While some of the artificial sweeteners in these two drinks have been linked to negative health effects, drinking them in moderation should not be a concern, especially when compared to the negative consequences of the sugar-laden alternative.

In terms of nutrition, Coke Zero and Diet Coke are nearly identical. The flavor is the main difference between them. Kombucha or a probiotic soda may be good alternatives if you want to avoid added sugars and non-nutritive sweeteners.
