Ever wondered how that "Smart Choices" sticker wound up on the front of boxes of Froot Loops or Cocoa Puffs?
Well, federal health officials are having similar thoughts, and they're warning food manufacturers.
The Food and Drug Administration said Tuesday that nutritional logos from food manufacturers may be misleading consumers about the actual health benefits of cereal, crackers and other processed foods. The agency sent a letter to companies saying it will begin cracking down on inaccurate food labeling. The FDA did not name specific products or give a timeline for enforcement.
U.S. manufacturers, including Kellogg, Kraft Foods and General Mills, rolled out their so-called Smart Choices program last year, amid growing concern about obesity rates. The green labels appear on the front of foods that meet certain standards for calories per serving and fat content.
But consumer advocates complain about lax standards for the program, with logos appearing on everything from frozen sweets to sugary cereals.
"There are products that have gotten the Smart Choices check mark that are almost 50 percent sugar," FDA Commissioner Margaret Hamburg said during a call with reporters.
There are more than a half-dozen labels crowding grocery packages, including the American Heart Association's heart-shaped logo, Giant Food Store's Healthy Ideas box and Supervalu's Nutritional IQ logo.
"There's a growing proliferation of forms and symbols, check marks, numerical ratings, stars, heart icons and the like," said Hamburg. "There's truly a cacophony of approaches, not unlike the tower of Babel."
The FDA plans to research whether one particular approach would make it easier for consumers to select healthy foods. Hamburg pointed to the success of the U.K.'s traffic light system, which uses red, yellow and green lights to highlight nutritional quality.
The Grocery Manufacturers Association in Washington had no immediate comment Tuesday afternoon.
Overall, foodmakers have begun responding to consumer demand for healthier foods by reformulating their staples. Such changes includes ConAgra's move to reduce sodium in its soup, hot dogs and other products, and General Mills adding fiber to its cereals.
