Oprah has notoriously been pro-vegan although she is not. She has challenged the meat industry with the Mad Cowboy and participated in a 21-day vegan cleanse in 2008 with the help of Tal Ronnen (vegan chef extraordinaire) and Kathy Freston. And now, along with her entire staff, she's doing a vegan 1-week challenge to show America that it's easy to eat healthy and break up your normal routine.
I think that there's no better way to teach people than to show them, so Go Oprah! (And your team of course)!
Maybe (for those of you who aren't) try a vegan weekend challenge!?!
