An ad by a U.S. non-profit group is creating some doubts about linkage between heart disease deaths and fast-food. The Physicians Committee for Responsible Medicine's ad has a woman sobbing. She has clasped the hand of a dead man lying in a morgue. There is a close-up shot of a half-eaten hamburger still in the dead man's hand. In the end, the ad shows the McDonald's arches superimposed on the man's dead feet and a voice saying the fast-food joint's altered punch line: I was lovin' it.

According to the spokesperson from Physicians Committee for Responsible Medicine, fast-food restaurants offer high-fat, high-sodium foods. This includes foods like KFC's Double Down Combo Meal, with 45 grams of fat and 2,120 milligrams of sodium, and McDonald's Double Quarter Pounder with Cheese Extra Value Meal, having 61 grams of fat and 1,650 milligrams of sodium.
