The Thrifty Food Plan (TFP) has a unique role in US Nutrition Policy, integrating both dietary guidance and antihunger policies. Not only are food items in the TFP market basket chosen based on the latest dietary recommendations, but the Plan serves as the basis for inflation adjustments to Food Stamp allotments. To be economical, the TFP logically assumes that most dishes are prepared from raw ingredients. This assumption likely contradicts welfare policy, which promotes increased labor force participation of low-income women. This article presents empirical evidence on meal preparation times in US households and compares this evidence to the TFP implicit assumptions about food preparation. The trade-offs between time and money inputs used in the preparation of meals are discussed using the economist's household production approach. Implications of policy contradictions are explored, as well as related needs for research and practice.
节俭食物计划（TFP）在美国营养政策中具有独特作用，它将膳食指南和反饥饿政策整合在一起。TFP市场篮子中的食品不仅是根据最新的膳食建议挑选出来的，而且该计划还作为食品券配给通胀调整的基础。为了节约成本，TFP合理地假设大多数菜肴是用原材料烹制的。这一假设可能与福利政策相矛盾，福利政策旨在促进低收入女性更多地参与劳动力市场。本文提供了美国家庭膳食准备时间的实证证据，并将这一证据与TFP关于食物准备的隐含假设进行了比较。使用经济学家的家庭生产方法讨论了膳食准备中时间和金钱投入之间的权衡。探讨了政策矛盾的影响以及相关的研究和实践需求。
