"The city health department unveiled a proposal Tuesday that would  bar cooks at any of the city's 24,600 food service establishments from using  ingredients that contain" "artificial trans fatty acids." "Among the fast foods  that would need to get an overhaul or face a ban: McDonald's french fries,  Kentucky Fried Chicken and several varieties of Dunkin' Donuts." "Health  Commissioner Thomas Frieden acknowledged that the ban would be a challenge for  restaurants, but he said trans fats can easily be replaced with substitute oils  that taste the same or better and are far less unhealthy. "It is a dangerous and  unnecessary ingredient," Frieden said. "No one will miss it when it's gone."" "A  similar ban on trans fats in restaurant food has been proposed in Chicago and is  still under consideration."  » original news
