Johns Hopkins Uses Workout Notices To Cut Coke Intake By 50%

Researchers at John Hopkins university are now suggesting that soda and other foods should use exercise warnings instead of calorie numbers to warn buyers about the effects of what they eat and drink.

Researchers put up signs in three shop windows with different messages, one sign warned teens about the number of calories in a soda, another showed that 10% of their daily caloric intake came from a single coke and the final sign explained that it would take 50 minutes to work off the Coke.

While the first two signs helped Coke sales plummet by 40% the final sign which explained workout requirement cut sales for teen in half.

One study researcher told the Daily Mail:

“People generally underestimate the number of calories in the foods and beverages they consume,” and “Providing easily understandable caloric information—particularly in the form of a physical activity equivalent, such as running—may reduce calorie intake from sugar-sweetened beverages and increase water consumption among low-income adolescents.”

The study was aimed at finding ways to curb type-2 diabetes and other health conditions including obesity and heart disease.

Do you think the warning system used for food should be changed to better reflect the true effects of food and drink on the body?
