Tim McGraw recalls childhood struggles, encourages people to help fight hunger in America

When Tim McGraw was a kid, he didn't always know where he'd get his next meal.

Those memories are part of the reason he taped public service announcements that begin airing this month to raise awareness of hunger in America.

The charity Feeding America says one in six Americans struggle to find enough food to eat, and approximately 5.7 million people receive emergency food assistance from them on any given week.
