Coke Zero and Diet Coke

Diet Coke
Diet Coke is a sugar-free soft drink produced and distributed by The Coca-Cola Company. It is the first new brand since 1886 to use the Coca-Cola trademark. The product quickly overtook the company's existing diet cola. Diet Coke is now being sold all over the world however there has been a few problems. The most commonly distributed version of Diet Coke relies on aspartame, which has been suggested to pose health concerns. Aspartame is one of the most intensively scrutinized food additives. Research published in 2007 for the British government's Food Standards Agency suggests that sodium benzoate is linked to hyperactive behavior and decreased intelligence in children. In January 2008 sodium benzoate was removed from production lines for Diet Coke sold in the UK, however it remains in other Coke products and other production locations.

Coke Zero
Coca-Cola Zero, or Coke Zero, is a product of The Coca-Cola Company. It is a low-calorie variation of Coca-Cola specifically marketed to men, who were shown to associate diet drinks with women. It is marketed as having a taste that is indistinguishable from standard Coca-Cola, as opposed to Diet Coke which has a different flavor profile. Coke Zero was Coca-Cola's largest product launch in 22 years. It is primarily marketed towards young adult males and has been nicknamed "Bloke Coke" in the UK. In the U.S, advertising has been tailored to its targeted market by describing the drink as "calorie-free" rather than "diet", since young adult males are said to associate diet drinks with women.
