Yum! Brands’ annual World Hunger Relief campaign is the world’s largest private sector hunger relief effort, spanning 117 countries, 36,000 KFC, Pizza Hut and Taco Bell restaurants and over one million employees, to raise awareness, volunteerism and funds for the United Nations’ World Food Programme (WFP) and other hunger relief agencies. Multi-Grammy Award winner and international superstar, Christina Aguilera, serves as the global spokesperson for World Hunger Relief.

This year, Christina Aguilera lends her powerful voice in a new public service announcement for Yum! Brands’ World Hunger Relief effort this fall. The new PSA captures Aguilera standing on a dark stage that is artistically illuminated by sparkling lights held by children. As Aguilera sings a soulful a capella rendition of Twinkle, Twinkle, Little Star, graphics illustrate how millions of children go to bed hungry. She urges people to join her turn hunger into hope.

The PSA will start airing in mid-October. Aguilera will also appear in World Hunger Relief restaurant posters with the quote “Together, we have the power to save lives and go from hunger to hope” and online efforts, including the campaign’s website, FromHungertoHope.com.

Aguilera has served as global spokesperson for World Hunger Relief since 2009. She also serves as an “Ambassador Against Hunger” for WFP where she has traveled on relief trips with the organization to Haiti and Guatemala.

Hunger and malnutrition are the number one risk to health worldwide – greater than AIDS, malaria and tuberculosis combined. Among the key causes of hunger are natural disasters, conflict, poverty, poor agricultural infrastructure and over-exploitation of the environment.

Recently, financial and economic crises, coupled with drought, high food prices and conflict affecting more than 13 million in the Horn of Africa, have pushed more people into hunger. Yum! is directing the first $1 million from its World Hunger Relief effort this year to help WFP provide food to families affected by hunger and suffering the effects of drought in the Horn of Africa. Novak and other senior executives and franchise leaders from KFC, Pizza Hut, Taco Bell and Yum! Restaurants International also traveled to Honduras last month to help WFP’s relief efforts in the country.

Consumers can visit this website or donate in the restaurants (no purchase necessary – see calendar below for dates that each brand’s participating restaurants begin their in–store campaign). Every U.S. dollar raised will go directly towards WFP’s operations to fight hunger around the world. One U.S. dollar provides four meals for hungry children at school.

Yum! plans to generate the equivalent of nearly $50 million in awareness of the hunger issue through a PSA, advertising, public relations, web–based communications and in–restaurant posters. The Company’s employees and franchisees will be volunteering their time around the globe at hunger relief agencies, food banks, soup kitchens and launching fundraisers.

Since World Hunger Relief launched in 2007, more than one million of the Company’s employees, franchisees and their families have volunteered more than 21 million hours to aid hunger relief efforts in communities worldwide. The effort has raised nearly $85 million for WFP and other hunger relief organizations and is helping to provide more than 350 million meals and save the lives of millions of people in remote corners of the world.

Yum! is also addressing hunger across the U.S. through its Harvest program. Since its launch over two decades ago, Harvest has become the largest prepared-food donation program in the world. Through Harvest, Yum! has donated over 125 million pounds of food, with a value of over $500 million, to those at risk of hunger in the U.S. The Company also has been the primary sponsor of the Dare to Care Food Bank in Louisville for nine years, and has donated nearly $9 million to this local agency.

Campaign Calendar: World Hunger Relief kicks off its fall campaign in the U.S. with Pizza Hut on September 25, Taco Bell on October 6 and KFC on October 17.
