Recent research has shown that the typical Supplemental Food Assistance Program (SNAP) family falls short in meeting the Thrifty Food Plan (TFP) nutritional guidelines that underlie the SNAP even when they typically have sufficient monetary resources to eat a healthful diet (i.e. to follow the TFP recommendations). However, the TFP does not consider labor cost. This study uses a basic labor economics technique to value labor in a home food production scenario that is required to reach the TFP nutrition and budget targets and calculates the total cost (inclusive of labor) associated with the TFP. This TFP consistent total cost is then compared, using several metrics, with the total cost associated with actual choices made by those families sharing the same profiles as current SNAP participants. Once labor is included, we find the TFP is not very thrifty and the mean household falls short of the TFP guidelines even with adequate monetary resources.
最近的研究表明，典型的补充食品援助计划（SNAP）家庭在满足 SNAP 所依据的节俭食品计划（TFP）营养指南方面存在不足，即使他们通常有足够的货币资源来食用健康饮食（即遵循 TFP 建议）也是如此。然而，TFP 并没有考虑到劳动力成本。本研究使用基本的劳动经济学技术来衡量家庭食品生产场景中的劳动力价值，这是达到 TFP 营养和预算目标所必需的，并计算与 TFP 相关的总（包括劳动力）成本。然后，使用几种指标，将与具有当前 SNAP 参与者相同特征的家庭所做出的实际选择相关的总成本与 TFP 一致的总成本进行比较。一旦包括劳动力，我们就会发现 TFP 并不非常节俭，即使有足够的货币资源，平均家庭也无法达到 TFP 指南。
