Coca-Cola has been the target of urban legends decrying the drink for its supposedly copious amounts of acid, or the "life-threatening" effects of its carbonated water. These urban legends usually take the form of "fun facts" — for example, "Coke can dissolve a tooth in 24-48 hours"; " highway troopers use Coke to clean blood from highways after accidents"; or "somebody once died in a Coke-drinking competition". All of these stories are false, and evidence has been presented in numerous cases against Coca-Cola since the 1920s that decisively proves that the drink is not more harmful than comparable soft drinks. It contains less citric acid than an orange. [2] [3] [4]. However, one unusual use for coke that is not an urban legend is as a rust-control substance - the phosphoric acid in coke converts iron oxide to iron phosphate , and as such can be used as an initial treatment for corroded iron and steel objects being renovated, etc.
The numerous urban legends about Coca-Cola have led the Urban Legends Reference Pages to devote a whole section of their site to "Cokelore".
While many nutritionists recognize that "soft drinks and other calorie-rich, nutrient-poor foods can fit into a good diet" [5], it is widely believed that Coca-Cola and other soft drinks can be harmful if consumed to excess, particularly to young children whose soda consumption competes with, rather than augmenting, a balanced diet. Studies have shown that regular soft drink users have a lower intake of calcium (which can contribute to osteoporosis), magnesium, ascorbic acid, riboflavin, and vitamin A. [6] [7]
The drink has also aroused criticism for its use of phosphoric acid [8] and caffeine [9], though many of these criticisms have been dismissed by the industry as urban myths. [10] [11]

right Diet Coke was introduced in 1982 to offer an alternative to dieters worried about the high number of calories present in Classic Coke.
There are many varieties of Coca-Cola produced by the company such as Diet Coke (introduced in 1982), which uses aspartame ( NutraSweet brand), a synthetic phenylalanine-based sweetener, to eliminate the sugar content of the drink; Caffeine-free Coke ; Kosher for Passover Coke (corn-sweetner is replaced with cane sugar); Cherry Coke (1985); Diet Cherry Coke ( 1986); Coke with Lemon ( 2001); Diet Coke with Lemon (2001); Vanilla Coke ( 2002); Diet Vanilla Coke (2002); and Diet Coke with Lime ( 2004).
In 2004, perhaps in response to the burgeoning popularity of low-carbohydrate diets such as the Atkins Diet, Coca-Cola announced its intention to develop and sell a low-carbohydrate alternative to Coke Classic, dubbed Coca-Cola C2. C2 contains a mix of high fructose corn syrup, aspartame, sucralose, and acesulfame potassium. C2 is designed to more closely emulate the taste of Coca-Cola Classic than Diet Coke does. Even with less than half of the calories and carbohydrates of standard soft drinks, C2 is not a replacement for zero-calorie soft drinks such as Diet Coke. C2 went on sale in the US on June 11 2004, and in Canada in August 2004.
Coca-Cola is the best-selling soft drink in most countries. Nevertheless, there are some places like Scotland, where the locally produced Irn Bru is more popular, and Quebec and Prince Edward Island, Canada, where Pepsi is the market leader. Coke is less popular in other places, including some Middle Eastern and Asian countries such as the Palestinian territories and India — in the latter, due to suspicions regarding the health standards of the drink, and in the former, due to anti-American sentiment or the perception that Coca-Cola supports Israel. Mecca Cola, an "Islamically correct" brand, has become a hit in the Middle East in the past few years.
