Some of the most famous celebs have found themselves sporting a milk mustache over the 16 years of this creative advertising campaign. Another Oscar-winner and working mother has joined the growing list–Hollywood favorite Susan Sarandon.

Sarandon, a continuously busy working mom, said she is the new face of the milk campaign because of her global interest in child health and nutrition.  She has been a celebrity ambassador for UNICEF for many years, focusing on HIV/AIDS, and, as of 2010, has become the Goodwill Ambassador for the United Nations Food and Agriculture Organization. She says the 2011 milk campaign, called Pour One More, and her U.N. work go hand in hand, with so many children in America nutritionally challenged. She stressed we need to educate parents and schools to make sure our kids are getting not only the calories they need but the right nutrition to stay healthy.

Sarandon said, “As moms we have tremendous power to influence our children and their habits.”  Sarandon is mother of actress Eva Amurri, 25, Jack Robbins, 23, and Miles Robbins, 18.

In a brief conversation with Working Mother, I asked Sarandon if she felt she has been successful getting her own children to buy into good nutrition.  Her answer was very positive. “You have to be creative and start early,” she told me. “Generally, my kids have good eating habits. They have been introduced to lots of different kinds of food and that helps.” She added they have never had soda in the house.

“I remember my daughter coming home from a friends’ (friend’s [house]) and saying, ‘you wouldn’t believe what they eat for breakfast!’” That seemed to be a good sign.

Her youngest son, Miles, is a freshman in college and she said he has maintained good habits even during that notoriously bad first year away.  He eats very little meat, though IS not a vegetarian.

She admitted it’s hard for working moms trying to get out the door everyday but she stressed that moms should be creative–a good milk shake or smoothie might be a good choice for some kids. And she criticized school food programs saying it’s up to parents to push for healthier lunch menus.

Pour One More came out of a study reporting that most Americans get less than half the required suggested servings of milk everyday (3 glasses for adults) and are low on important nutrients found in milk, like vitamin D, calcium and potassium. By pouring one more glass of milk or its equivalent in a smoothie, cereal bowl or shake, it would be easy to increase servings. The campaign says the simple message is doable.

As for Sarandon’s other interests, at 64, she continues to find new projects even beyond acting and charity.  In 2009, she along with some partners opened a ping pong club (like a high-end billiards club) in Manhattan, where she lives, called SPiN, and has since opened another in Los Angeles. SPiN is complete with a restaurant, bar and of course celebrity players and friends. “I never really thought I’d be an entrepreneur,” she said.  The press has called her both the “godmother of ping pong” AND the sport’s “Johnny Appleseed.”

The game of ping pong, both its athletic side that it’s played in a relatively small space, appeals to her.  So she is taking it on the road and creating a charity, working with New York City public schools.  The charity is not only donating tables but helping run ping pong programs and actively creating team play. Her dream is to take the small white ball and paddles to schools across the country and grow interest along with expanding SPiN club franchises.

There is another ping pong possibility in Sarandon’s life. She and her partners are hoping to create a reality TV show. No further word on that for the entrepreneurs.

Hollywood is still calling.  Sarandon will reunite with Al Pacino in a new film titled Arbitrage, a Wall Street-related drama. They have signed contracts, but she says, she does not know when that will move forward. I wonder if it will have a ping pong scene in it or a glass of milk?
