A food stamp challenge or SNAP challenge is a trend in the United States popularized by politicians, religious groups, community activists and food pantries, in which a family of means chooses to purchase food using only the monetary equivalent of what a family that size would receive in the US federal government Supplemental Nutrition Assistance Program (SNAP), colloquially called food stamps. In 2015, this amounted to US$194.00 per person per month, or $6.37 per day.
