We do have sugar-free cokes, but what’s the difference between diet coke and coke zero? We hear a lot about controlling the amount of sugar in our diet. This is because sugar hardly has any nutritional value.

Moreover, according to many nutritionists, it is addictive and just a source of consuming extra calories. One common source that we consume sugar from is coke. This article includes all you need to know about Diet Coke and Coke Zero Sugar (also known as Coke Zero) from Coca-Cola, and what’s the difference between diet coke and coke zero.

The Coca-Cola Company

The Coca-Cola Company was founded on 29th January 1892 and deals in the beverage industry. With over 85,000 employees, Coca-Cola specializes in manufacturing, retailing, and marketing non-alcoholic drinks and syrups and alcoholic beverages.

Coca Cola’s Famous Products

The company is famous for its soft drinks such as Fanta and a lemon or lime soft drink, Sprite. Coca-Cola also launched TaB as a calorie-free beverage, using saccharin as a calorie-free sugar substitute. However, as Diet Coke came into the picture, the sales of TaB started dwindling. Diet Coke was another try by Coca-Cola at producing a calorie-free drink with a lighter taste.

Coca-Cola also started selling healthy beverages like Minute Maid, Powerade, Dasani water, and Fruitopia. These came under the company’s new segment of non-carbonated drinks. Non-carbonated beverages are free of sodas.

C2, launched by Coca-Cola, was another low-carbohydrate beverage that used Aspartame, Acesulfame K, and sucralose as its main ingredients. But it was later replaced by Coca-Cola Life in 2013.

Apart from C2, Coca Cola zero sugar drinks also worked their magic on the public. Two drinks produced under this idea are Diet Coke and Coke Zero.

These original Coca-Cola drinks use caramel color and carbonated water as two ingredients, with a blend of natural flavors and sweeteners. But what’s the difference between Diet Coke and Coke Zero Sugar? Read on to know more.
