LOS ANGELES -- Public Enemy No. 1 in America's battle of the bulge isn't cupcakes, soda or double bacon cheeseburgers. It's the simple potato, according to Harvard University researchers.
Daily consumption of an extra serving of spuds -- french fried, sliced into crispy chips, mashed with butter and garlic, or simply boiled or baked -- was found to cause more weight gain than downing an additional 12-ounce can of a sugary drink or taking an extra helping of red or processed meats.
