.Coca-Cola in Autralia ran this advert on October 11th 2008.
Coke claimed that it was a “myth” that Coke made children fat or caused their teeth to rot using celebrity endorsements.

And they soon after gave wrong data regarding Cokes content of caffeine.

The company for a period of 3 years, will also ensure that it will not make the claims that:

• that consumption of Coca-Cola cannot contribute to weight gain unless that claim can be substantiated;
• that consumption of Coca-Cola cannot contribute to tooth decay or that tooth decay is declining globally, unless the particular claim made can be substantiated;
• that 250ml of the Coca-Cola Product bearing the brand name “Diet Coca-Cola” contains only one half of the amount of caffeine as that contained in a cup of tea, without further qualification, unless that claim can be substantiated.
