'Healthy' food may result in more calories

ITHACA, N.Y., Aug. 29 (UPI) -- U.S. consumers choose relatively high-calorie beverages, side dishes and desserts to go with restaurant main dishes positioned as “healthy,” a study found.

Brian Wansink of Cornell University, in Ithaca, N.Y., and Pierre Chandon of Institut Europeen d' Administration des Affaires in Fontainebleau, France, had consumers guess how many calories were in sandwiches from two restaurants. The consumers estimated that sandwiches from restaurants claiming to be healthy had 35 percent fewer calories than those from restaurants not making the claim.

The researchers found that the beverages, side dishes and desserts chosen by consumers eating a “healthy” main dish contained up to 131 percent more calories than similar offerings in other restaurants.

The finding helps explain why the success of fast-food restaurants serving lower-calorie foods has not led to the expected reduction in total calorie intake and in obesity rates, reported the study published in the Journal of Consumer Research.

The researchers suggest people examine whether a restaurant’s health claims actually apply to the particular food they ordered, to eliminate what they called the "health halo" effects.

"More generally, we need to think about food not just qualitatively, as in 'good food -- bad food,' but also quantitatively, as in 'how many calories are in this meal?'" the researchers said in a statement.
