In this Monday, July 28, 2008, photo, Sharon Robinson makes Tropical Punch Kook-Aid, which is made by Kraft Foods, in Palo Alto, Calif. The death of Trayvon Martin, 17, at the hands of a neighborhood watchman in February ignited many demonstrations of protestors carrying bags Skittles while marching for the arrest of shooter George Zimmerman. But Skittles are not the first popular food brand to find itself at the center of a major controversy. The terms ?the Twinkie defense? and ?don't drink the Kool-Aid? became part of the vernacular decades ago in the wake of tragic events. More recently, Doritos made headlines when it was reported that the corn chips were Saddam Hussein's favorite snack. (AP Photo/Paul Sakuma)
