The decision to live on the budget which is based on Supplemental Nutritional Assistance Program (SNAP) was made after the Oscar-winning actress accepted to join the "#FoodBankNYCChallange" from celebrity chef and NYC Food Bank board member Mario Batali, reported Ace Showbiz.
The 42-year-old mother of two took to Twitter to announce that she was joining the charity challenge.
She shared a picture showing a range of healthy food options that include cilantro, corn, limes, whole grain brown rice, some black beans and eggs.
Later in the day, she added on Twitter, "We're walking in their shoes to see how far we get." In the tweet Paltrow also challenged chef Roy to join the challenge and donate.
The "#FoodBankNYCChallange" is a challenge aimed at raising awareness about hunger and the struggle to live on only USD 29 per person for seven days. It is also meant to raise funds for the food bank.
