Some of the nation's largest food companies have cut calories in their products by more than 6.4 trillion, according to a new study.
The study sponsored by the Robert Wood Johnson Foundation found between 2007 and 2012 the companies reduced their products' calories by the equivalent of around 78 calories per person per day. The total is more than four times the amount those companies had pledged to cut by next year.
Seventy-eight calories would be about the same as an average cookie or a medium apple, and the federal government estimates an average daily diet at around 2,000 calories. The study said the calories cut averaged out to 78 calories per day for the entire U.S. population.
