A lawsuit was filed Tuesday in New Jersey District Court alleging the "Heart-Check" certification Campbell Soup Company uses on some products is misleading. The lawsuit, which seeks class action status, says the American Heart Association's (AHA) "Heart-Check" certification does not properly convey the benefits of eating the product, and AHA allows companies to use the logo on products that run counter to its stated mission in exchange for fees.

"Heart-Check" certification is awarded to products containing 480 milligrams or less of sodium per serving, even though AHA's website defines low sodium as 140 milligrams or less of sodium per serving. "The AHA, for a fee, abandons its general, non-commercial dietary and nutritional guidelines," the lawsuit states, according to the AP. Campbell says it has not yet been served with a lawsuit, and the AHA says it will not comment on pending litigation.
