Mayim Bialik - Mayim Bialik Starring In Vegan Campaign

THE BIG BANG THEORY star Mayim Bialik is urging fans to ban animal products from their diet as part of a new campaign to promote veganism.

In the new print advertisement, the actress poses as a 1950s housewife and tosses a steak into the garbage under the tagline, "It's a No-Brainer: Go Vegan!"

The advert concludes, "The only way to be sure that meat doesn't poison your family is to throw it out. Protect your families (and animals!) now by choosing vegan."

Bialik reveals she signed up for the People for the Ethical Treatment of Animals (Peta) campaign because she has always felt guilty for eating meat.

She says, "I've never had a sinus infection or been on antibiotics since cutting out dairy. I think the most significant shift for me was I used to feel guilty. 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."
