'The Big Bang Theory' Star Goes Vegan In New PETA Ad

Mayim Bialik, of the award-winning show "The Big Bang Theory," speaks out in support of a vegan lifestyle in a new ad with animal rights organization, People for the Ethical Treatment of Animals . For the ad, Bialik plays a 1950s housewife happily tossing a piece of steak into a trash can under the sign "It's a No-Brainer: Go Vegan!" A vegan in her own life, Bialik talks with PETA about how she decided to embrace a vegan lifestyle. "I think the most significant shift for me was I used to feel guilty," Bialik told PETA. "Even as a child, I felt very guilty about eating animals and never knew that there was something to do about it. And as I got older, it became clearer that there are things that I can do and choices I can make." Becoming vegan was a natural decision for Bialik, one that she says has changed her life for the better. "I've never had a sinus infection or been on antibiotics since cutting out dairy ...I've noticed that my true seasonal allergies are much less severe now that I've cut out dairy which is amazing to me."

Wolowitz has finally traveled to space in The Big Bang Theory, but he'll soon come to realize that being far away from home doesn't mean you can escape your controlling mother. While on the spaceship, Wolowitz has an opportunity to chat with his mom (although, not through Skype because she refuses to go near a computer in case she catches a "computer virus").  Then he brings up a touchy issue: he and Bernadette want to go start their life together and move out.  His mother seems to be a travel agent for guilt trips and convinces him that leaving her would not be in anyone's best interest.
