Jennifer Aniston ate a McDonald's Big Mac burger and lived to tell about it.
"I'll never forget when Justin and I were on a road trip and we were so hungry," Aniston says. "The only thing around was McDonald's. I think I ordered a Big Mac. Wow, my body did not react well to that! It was like putting gasoline in a purified system. I am always trying to eat organic and natural foods, so that just made my stomach turn and made me feel terrible. And I think what you put in your body, as well as stress, is reflected in the quality of your skin."
