摘要
最低成本饮食问题利用食物选择对健康的影响,向学生介绍了优化和线性编程。我们提供了一个图形示例、Excel 工作簿和 Word 模板,使用项目价格、食物成分和营养素需求的实际数据进行简短练习,让学生猜测并求解最低成本下的营养素充足率,然后将模型膳食与不同营养素充足率的实际消费进行比较。图形示例是由玉米、豆类和南瓜组成的 "三姐妹 "膳食,而完整的多维模型则与埃塞俄比亚目前的食物消费进行比较。这种最新的斯蒂格勒饮食法显示了成本最小化与效用最大化之间的关系,并与当前关于全球健康饮食可负担性的研究和政策辩论相联系。
Least-cost diets to teach optimization and consumer behavior, with applications to health equity, poverty measurement and international development
The least-cost diet problem introduces students to optimization and linear
programming, using the health consequences of food choice. We provide a
graphical example, Excel workbook and Word template using actual data on item
prices, food composition and nutrient requirements for a brief exercise in
which students guess at and then solve for nutrient adequacy at lowest cost,
before comparing modeled diets to actual consumption which has varying degrees
of nutrient adequacy. The graphical example is a 'three sisters' diet of corn,
beans and squash, and the full multidimensional model is compared to current
food consumption in Ethiopia. This updated Stigler diet shows how cost
minimization relates to utility maximization, and links to ongoing research and
policy debates about the affordability of healthy diets worldwide.
