What is Diet Coke?

Diet coke is defined as a low-calorie and sugar-free cold beverage that is an alternative to regular Coca-Cola (coke). This is unlike any other cola that contains added sugar.

But have you ever wondered how diet coke has the same sweet flavour when it is actually sugar-free? For this purpose, the manufacturers include artificial sweeteners such as aspartame, sucralose, cyclamates, etc.

History Of Diet Coke

Diet Coke history is 40 years old. When the manufacturers created Diet Coke. But within two years, this beverage became the world’s favorite light cola, and it still is!

In its advertising, it is shown that “Diet Coke encourages an individual to love what they love to do, celebrate the long-lasting attitude that comes with knowing who they are and what they are into.”

But is it so? In several studies, these beverages are considered unhealthy to consume. Only adding “diet” in its name doesn’t make it a so-called ‘healthy food.’ It is not considered a nutritious drink. It is simply a slurry of chemicals that may deleteriously affect the human body.

Diet Soda Isn’t Nutritious

 Our diet coke is mainly a mixture of carbonated water, artificial sweeteners, color, flavor, and other food additives. Usually, it has very few to no calories and no noteworthy nutrition.

Such as 354 ml of diet coke, which contains no calories, sugar, fat, or protein. But has 40mg of sodium. However, not every soda or diet coke uses artificial sweeteners that are low in calories or sugar-free. Many manufacturers use sugar and sweetener together as a mixture. Such as a ‘can’ of Coco-Cola diet coke, which contains the natural sweetener stevia but has 90 calories and 24gm of sugar in it.

Common Ingredients In Diet Coke

So, the manufacturing of these beverages differs from brand to brand, but some common ingredients in diet soda include:

  • Carbonated Water: Many water sodas or beverages like diet coke are made by dissolving carbon dioxide into water under pressure.
  • Sweeteners: These beverages include artificial sweeteners, for example, aspartame, saccharin, sucralose, or stevia, which is an herbal sweetener. Stevia is 200 times sweeter than regular artificial sweeteners.
  • Acids: A few manufacturers also add a certain number of acids, such as citric, malic, and phosphoric acids. Such acids are used to add tartness to soda drinks. Also, these acids are responsible for tooth enamel erosion.
  • Colors: Commonly used are carotenoids, anthocyanins, and caramels in beverages like diet coke.
  • Flavors: Did you know there are many different kinds of natural juices or artificial flavors that are used in diet soda? This includes fruits, berries, herbs, and cola.
  • Preservatives: The presence of potassium benzoate, a preservative in beverages helps diet coke or other soda last longer on the supermarket shelf.
  • Vitamins and Minerals: Many manufacturers add vitamins and minerals to their products to market them. Keeping these minerals as their USP and showing that their product is healthy and calorie-free to consume.
  • Caffeine: Just like any regular soda, diet coke may also contain caffeine. Did you know a can of diet coke contains 46mg of caffeine, whereas a can of diet Pepsi contains 35mg?

Reasons To Quit Drinking Diet Coke

  1. Contains Carcinogens

Did you know diet coke contains caramel coloring? Caramel coloring is created by heating sulfites and ammonia. After heating these two chemicals, we get carcinogens. However, tests on mice and rats showed that such chemicals in high doses can cause tumors in the thyroid, lungs, and liver.

  1. Makes Bones Weak

According to many studies, consuming any type of soda can worsen osteoporosis. A few observations revealed that the bone mineral density among women drinkers was 4-5% lower than that of those who drank healthier beverages.
