The queen of daytime television, Oprah Winfrey, has decided to go vegan for 21 days. And she invites her viewers to join her.

Oprah's stated reason? "How can you say you're trying to spiritually evolve without even a thought about what happens to the animals whose lives are sacrificed in the name of gluttony?" As an added benefit, she expects to cleanse her body of the saturated fat, cholesterol, pesticides, antibiotics and pathogens contained in animal products.

I hope that Oprah's experience leads her to continue a vegan diet for life. And I invite readers to take her 21-day challenge and discover the benefits for themselves.
