The 2018 Farm Bill mandates that the market basket of the Thrifty Food Plan (TFP) be updated every 5 years using current food prices, food composition, food consumption patterns, and dietary guidance. The TFP forms the basis of the maximum allotment for the U.S. Department of Agriculture's Supplemental Nutrition Assistance Program (SNAP) benefits. Current food composition and food consumption data are available through What We Eat in America, the dietary component of the National Health and Nutrition Examination Survey (WWEIA/NHANES). The Dietary Guidelines for Americans provides current dietary guidance. However, food price information that aligns with these data are not available, which limits the economic analysis that can be conducted with the survey data. This report details the construction of the Purchase to Plate Price Tool (PPPT), which uses retail or household scanner data to estimate prices for foods reported consumed by participants in WWEIA/NHANES and compares estimated total food expenditure of WWEIA/NHANES participants to other estimates of food expenditure.
