Keeping that in mind, the coca-cola company brought coke zero as an alternative, allowing people to enjoy coke cola without compromising health.

    In 2017, the reformation in the branding of coke zero took place. Coca-cola announced that they would relaunch coke zero with the name ‘coke zero sugar.’ The relaunched stated that with coke zero sugar, customers would enjoy Coca-Cola’s original taste while keeping their health on track.

    The coca-cola zero doesn’t contain any carbs or calories, making it perfect for the people following the keto diet. Apart from this, some people also prefer it because it has a unique taste from the original coca-cola.

    7. Potassium Citrates


    Aspartame and Acesulfame-K are the main ingredients used in coke zero as a sweetener. Many people have criticized these sweet alternatives as they can negatively impact your health.

    According to many experts, Aspartame is the ingredient that brings along some disadvantages. It consists of two amino acids named phenylalanine and aspartic acid. Phenylalanine can result in some allergic reactions or cause gastrointestinal side effects. It may also lead to some other health conditions like diabetes. 

    However, U.S Food and Drug Administration (FDA) and other high authority organizations have approved Aspartame as a safe sweet alternative. But, in the last few years, some research was conducted, in which they found that Aspartame can lead to some health issues, like:

    • Irritable mood
    • Migraines
    • Insomnia
    • Seizures
    • Anxiety

    More frequent intake of artificial sweeteners is also not preferable for pregnant women. It can lead the child to be more inclined towards sugar cravings.

    Apart from artificial sweeteners, Caramel color is another ingredient that may create problems. 

    Dr. Berg explains that producing caramel color results in a compound named Advanced Glycation End Product (AGE) harmful to our body. It is produced when the fat or protein is combined with sugar in the bloodstream. 

    AGE forms sticky proteins in your various body parts like the brain, arteries, pancreas, liver, etc. If consumed for a more extended period, this may lead to severe health issues.
