The 30-second ad, a version of which ran in Brazil last month, is intended to address confusion about the number of calories in soda, said Diana Garza Ciarlante, a spokeswoman for Coca-Cola Co. She said the company's consumer research showed people mistakenly thought there were as many as 900 calories in a can of soda.
The company declined to say how much it was spending on the commercials, which it started putting together last summer. It also declined to give details on its plans for the year ahead. But among the options under consideration is putting the amount of activity needed to burn off the calories in a drink on cans and bottles.
The company noted that it already puts calorie counts on the front of its cans and bottles. Last year, it also started posting calorie information on its vending machines ahead of a regulation that will require soda companies to do so by 2014.
Coca-Cola's changing business reflects the public concern over the calories in soda. In North America, all the growth in its soda unit over the past 15 years has come from low- and no-calorie drinks, such as Coke Zero. Diet sodas now account for nearly a third of its sales in the U.S. and Canada. Other beverages such as sports drinks and bottled water are also fueling growth.
Even with the growing popularity of diet sodas, however, overall soda consumption in the U.S. has declined steadily since 1998, according to the industry tracker Beverage Digest.
John Sicher, the publisher of Beverage Digest, noted that the industry "put its head in the sand" when obesity and soft drinks first started becoming an issue more than a decade ago. Now, he said Coca-Cola is looking to position itself in the public debate rather than being defined by adversaries.
