Hollywood actress and food and lifestyle writer, Gwyneth Paltrow, has confessed her family failed in its attempt to survive on $29 worth of food for a whole week—the equivalent of what poor families in the U.S. get in food stamps.

The actress and her family, as well as Paltrow's colleagues at her website Goop.com, took part in the challenge as part of a campaign to raise awareness for the Food Bank For New York City, which provides free meals to the city's poorest.
