Adding ‘activity counts’ to food packaging might better help consumers make more informed eating choices.
BURN IT OFF

Knowing how long it takes to run off a pizza might help fight the obesity crisis

If food companies listed on their products just how long a person would have to walk or run to burn off the calories they consumed, people would be healthier. At least, that’s what Britain’s Royal Society for Public Health says.

In an opinion piece published April 6 in the British Medical Journal, the society’s director, Shirley Cramer, argued that giving consumers an immediate link between a food’s energy content and physical activity will help them make more informed decisions about what they choose to eat. Calorie counts alone aren’t enough, she wrote. Some 44% of people in Britain find front-of-pack information confusing.

“Such information needs to be as simple as possible so that the public can easily decide what to buy and consume in the average six seconds people spend looking at food before buying,” Cramer wrote.

In Britain, more than two-thirds of the population are either overweight or obese. In the US, the National Institutes of Health estimates nearly 70% of the population is overweight or obese.

As part of its case, the Royal Society for Public Health drew up a table (pdf) that gives a sense how much exercise some types of foods and drinks would require to burn off:

Food typeCalories (approx.)Walk off timeRun off time
Soft drink13826 mins13 min
Chocolate bar22942 min22 min
Sandwich4451 hr 22 min42 min
Large pizza4491 hr 23 min43 min
Medium mocha29053 min28 min
Potato chips17131 min16 min
Dry roasted peanuts29654 min28 min
Cinnamon roll4201 hr 17 min40 min

Cramer wrote that there’s no evidence yet that activity labeling would change people’s behavior, but said initial work is promising. Public health advocates are interested.

The US food industry, represented by the Grocery Manufacturers Association, is typically leery of suggestions involving package redesign because it’s expensive. GMA spokesman Brian Kennedy said  while activity labeling is an interesting concept, it needs further research. When the US government mandated food be labeled with Nutrition Facts in the 1990s, the industry howled.
