Food purchasing and preparation practices were modified in two boarding high schools to increase the polyunsaturated-to-saturated fat ratio (P/S) of the diet of students by changing food products rather than attempting to change eating behaviors. During years when fat-modified products were served, the P/S of males increased by 75 percent, versus a decrease of 6 percent during control years. For females, P/S increased by 53 percent during intervention years, versus an increase of 6 percent during control years.
两所寄宿制高中改变了食品采购和制备方式，通过更换食品种类而非试图改变饮食习惯，来提高学生饮食中多不饱和脂肪与饱和脂肪的比例（P/S）。在供应脂肪改良食品的年份里，男性的P/S值增加了75%，而在对照年份则下降了6%。对于女性而言，干预年份的P/S值增加了53%，对照年份则增加了6%。
