Coke Zero vs Diet Coke: The Shocking Difference You Don’t Know About

You and I could argue until we’re blue in the face about whether or not Diet Coke and Coke Zero taste the same. At first glance (or sip?) you can’t really tell the two massively popular drinks apart.

But according to Coca-Cola, there really IS a difference between diet coke and coke zero.

In a statement on their website, the brand stacks the two fizzy drinks against one another: “Both drinks are sugar free and calorie free. Coca-Cola Zero Sugar looks and tastes more like Coca-Cola Classic, while Diet Coke has a different blend of flavours which gives it a lighter taste.”

The key difference between diet coke and coke zero is a single chemical.

While Zero Sugar features sodium citrate in its list of ingredients, Diet Coke contains citric acid.

Diet Coke was Coca-Cola’s first sugar-free soda, and was launched in 1983.

The next sugar-free drink they offered, Coca-Cola Zero, didn’t come until 2006. It was knocked off the shelves in 2016, and reintroduced with the new name Coca-Cola Zero Sugar.

The company’s low-calorie drinks make up a mouthwatering 43 percent of all its cola sales, so obviously their recipes include a few sprinkles of magic fairy dust.

List Of Ingredients

1. Diet Coke

Carbonated water, caramel color, aspartame, phosphoric acid, potassium benzoate, natural flavors, citric acid, caffeine.

2. Coke Zero Sugar (formerly Coke Zero)

Carbonated water, caramel color, phosphoric acid, aspartame, potassium benzoate, natural flavors, potassium citrate, acesulfame potassium, caffeine.

Diet Coke is missing two ingredients that the other two sugar-free options have: potassium citrate and acesulfame potassium. Acesulfame potassium is a calorie-free sugar substitute and potassium citrate is a common additive in beverages.

Do these ingredients differentiate them nutritionally? Not in the slightest.

Diet Coke’s nutritional information reads: 0 Calories, 0g Fat, 40mg Sodium, 0g Total Carbs, 0g Protein.
Coca-Cola Zero’s nutritional information reads: 0 Calories, 0g Fat, 40mg Sodium, 0g Total Carbs, 0g Protein.
And Coca-Cola Zero Sugar also reads: 0 Calories, 0g Fat, 40mg Sodium, 0g Total Carbs, 0g Protein.

Although they both contain caffeine, the amount varies:

Regular Coke 9.7 mg/100ml

Diet Coke 12.8 mg/100ml

Coke Zero 9.6mg/100ml

As you can see, the amount of caffeine in Coke Zero is almost identical to that of Regular while the levels are higher in Diet Coke. The fact that both Coke Zero and regular coke have virtually the   same amount of caffeine must account for the almost indistinguishable taste.

Both contain no kilojoules (calories) and no sugar. Both are artificially sweetened with (the same amount) of aspartame and acesulfame K and therefore have the same ‘sweetness’.

And the most important question: which drink is the most popular?

Statistics suggest that even after all this time, regular coke is still the highest-selling soft drink, followed by Pepsi and Diet Coke, which holds the third spot.

Unfortunately, Coke Zero has never been featured on the Top 10 list, but it’s apparently growing in popularity.

So… which is healthier?

Despite both Coke Zero Sugar and Diet Coke being branded as the healthier alternatives to regular coke, neither of them are actually good for you.

Although they may not have sugar in their list of ingredients, both Diet Coke and Coke Zero feed your habit of consuming extremely sugary drinks. This means that your taste buds get used to that level of sweetness and will continue to seek them out. In fact, studies have shown that it can actually lead to an increase in caloric and sugar consumption, and result in long term weight gain. The phosphoric acid content isn’t healthy either, as it can damage tooth enamel which contributes to dental erosion.

Nonetheless, if you absolutely had to make a choice between regular and diet/zero sugar, we would say the latter would probably be a healthier choice. Just remember, “healthier” does not mean ‘healthy’.

If you ask us what we think the best drink is? It’s water. Hands down.
