Drew Barrymore said Monday she is donating $1 million to help fight hunger.

She made the announcement on "The Oprah Winfrey Show," saying she would give the money to the World Food Program, a U.N. body that delivers millions of tons of food aid to more than 70 million people in about 80 countries.

"I'm able to make this incredible donation — this has changed my life," she said on the program. "But I encourage everyone to give."

Barrymore, who serves as a World Food Program ambassador, later told The Associated Press that the $1 million is the largest donation she's made.

"By far," the 33-year-old actress said. "But nothing has ever felt so good."
