Alicia Keys has found a new way to give up her favourite unhealthy food - eat the snacks on film sets.The R&B star has given up corn fritters after eating them in character for take after take while making The Secret Life of Bees in North Carolina.She explains, "We had these great chefs from the local area, who had their own store and restaurant, Two Moms. "I ate those corn fritters, and the sweet potato pie and the corn bread and everything else that was on those plates. The corn fritters I had to eat a lot of times in one scene so I now don't like them anymore."Keys admits she learned that there are rules to eating in movies: "If you actually eat and swallow once, you have to keep eating and swallowing to keep the scene looking the same. "If you speak the line and you're actually chewing, you can't speak the line again and not have that food in your mouth. After corn fritter 75 or so, I did start to spit them out. That was enough."
