The Oscars aren't only about which actress will win and what she's wearing. The actors and actresses nominated for the 2012 Academy Awards are often role models, leading by example at everything from giving back to staying fit and eating right. And that means they can teach us (sometimes surprisingly!) valuable health lessons.
They don't have to star in health-themed films to get a message across. It might be an actor's personal fitness mantra that resonates with fans, or the way an actress speaks out about a health cause she is passionate for.
