WASHINGTON (AP) — A study finds that some of the nation's largest food companies have far exceeded calorie cutting goals they set for their products in 2010.

The study sponsored by the Robert Wood Johnson Foundation found that the companies cut the equivalent of around 78 calories per person per day. The total is more than four times the 1.5 trillion calories 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.

The companies include General Mills, Campbell Soup, ConAgra Foods, Kraft Foods, Kellogg, Coca-Cola, PepsiCo and Hershey.

The Robert Wood Johnson Foundation is a nonpartisan philanthropic and research organization which signed on to hold the companies accountable.

Many off-label brands sold under the names of retailers aren't included in the study and it's unknown whether those products have changed.
