许多学生认为，时间不足是决定他们在学校午餐吃什么的主要限制之一。在一些学校，学生只有15-20分钟的时间购买和吃午餐，这可能会鼓励学生选择更方便且通常不太健康的选择，例如热狗或鸡肉馅饼。这项研究的目的是通过使健康食品更方便，鼓励学生吃得更健康。在干预之前，在自助餐厅测量了6周的食品销售，消费和食物浪费，其中有两条相同的服务线，两条线上都有健康和不太健康的食物。然后，其中一条线路被转换成一条快线，只提供健康的选择，如三明治，沙拉，酸奶和水果。另一行保持不变，提供所有项目。销售，消费和食物浪费进行了6周的测量。结果显示，在推出快速线后，购买健康物品的数量增加了21%，购买不健康物品的数量增加了8%。虽然购买的不健康物品略有增加，但这些物品的总消费量下降了38%。这项研究表明，改变现有食物选择的便利性可以大大改变购买行为和学校午餐室食物的消费。
Many students cite lack of time as one of the major constraints determining what they eat for lunch at school. In some schools, students receive as little as 15–20 minutes to purchase and eat their lunch which may encourage students to take the more convenient and often less healthy options such as a hot dog or chicken patty. The goal of this study was to encourage students to eat healthier by making the healthier foods more convenient. Food sales, consumption and food waste were measured for 6 weeks before the intervention in a cafeteria where there were two identical serving lines and both healthier and less healthy items were available on both lines. Then, one of the lines was converted into an express line that only offered healthy options such as sub sandwiches, salad, yogurt and fruit. The other line remained the same offering all items. Sales, consumption and food waste were measured for 6 weeks. Results show a 21% increase in the number of healthy items purchased and an 8% increase in unhealthy items purchased after the introduction of the express line. Although there was a slight increase in unhealthy items purchased, total consumption of these items decreased by 38%. This study indicates that changing the convenience of existing food options can drastically change purchasing behavior and consumption of foods available in the school lunchroom.
