A. At first glance, Diet Coke and Coke Zero appear to be identical. 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’.
NOTE: THESE PRODUCTS ARE WHAT'S AVAILABLE IN AUSTRALIA WHERE I LIVE. IT'S A DIFFERENT STORY IN THE USA WHERE CORN SYRUP IS THE MAIN SWEETENER EXCEPT AT JEWISH PASSOVER SO PLEASE BEAR THIS IN MIND AS YOU READ.
However, there are three very subtle differences between Diet Coke and Coke Zero:
1. Since its launch in 1982, Diet Coke has been popular with people conscious of their weight, especially women. In 2005 Coca Cola Amatil launched a similar product, Coke Zero, but with more ‘masculine’ looking packaging to appeal to males. Coke Zero has even beennicknamed "Bloke Coke".
2. 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
Therefore, the amount of caffeine in Coke Zero is almost identical to that of Regular Coke and higher in Diet Coke. Most consumers would agree that Coke Zero tastes more like regular coke. This could be due to both having virtually the same amount of caffeine.
3. The food acids used are different. Regular Coke contains 338 (phosphoric acid), Diet Coke contains 338 and 330 (citric acid), whilst Coke Zero contains 338 and 331 (sodium citrate). Not much of a difference really but at least you know.
And which is the most popular?
So which is the best to drink? We advocate water as the ideal drink. Add lemon or lime to make it taste nicer. We don’t recommend you drink ordinary soft drink. There’s nothing nutritious or healthy about soft drink. But if you’re need to lose weight or have type 2 diabetes, diet drinks can make your life more pleasant without adding kilojoules. Drink them occasionally say if you’re out. Even without sugar, you’re still consuming something sweet and your taste buds get used to that level of sweetness. The odd one when you’re out is fine but don’t make a habit of them. See here for reasons why. And their acidity and phosphoric acid is not healthy either. It can damage tooth enamel which contributes to dental erosion.

Note: Preservative 211 is sodium benzoate which is commonly used to extend the shelf -life of soft drinks, cordials and fruit drinks. It is needed in both sugar-free diet drinks but NOT in the regular Coke as the sugar does the job of preserving the drink witout refrigeration.
