America’s obsession with sweets isn’t always a bad thing. We’re eating more vitamin-packed sweet potatoes than ever: about seven pounds a year per person, up from only 3.8 pounds in 2002. It helps that fast-food restaurants, including Wendy’s and Burger King, have put them on the menu. And celebrities are touting them, too: Oprah Winfrey says they’re one of her favorite foods, and Glee‘s Matthew Morrison follows a sweet potato-only diet before photo shoots. Get your fill with Guy Fieri’s Whiskey-Glazed Sweet Potatoes and Ree Drummond’s Soul Sweet ‘Taters, then vote for your favorite.
