Carrie Underwood has been one of music's most famous vegetarians for years, but now she's gone completely vegan. That means Carrie doesn't eat any food that came from an animal like milk or eggs. Carrie was inspired to make the change after seeing a woman she works with just looking radiant one day. "Something had happened in her life. There was some switch flipped," Carrie explains. "Her skin was glowing. Her eyes were gorgeous. Like, her body was amazing." When that girl told Carrie it was all because of going vegan, Carrie decided to give it a shot. As a result, Carrie has discovered she had some issues with eating dairy products. She explains, "My reflex has gotten a lot better and things like that, and I think it was 'cause of dairy." Going vegan has led Carrie to make healthier eating choices like forgoing that cheesy pasta when she eats out. She's not sure if she'll stick with the diet long term though. "Someday we will have a farm, and I will have some pet chickens," Carrie reveals. You can see the results of Carrie's vegan diet in her latest video for "Good Girl." That's the lead single from Carrie's new album, Blown Away, due out May 1.
