在过去的20年里，我们北卡罗来纳大学教堂山分校的营养和经济学研究小组使用了一系列方法来研究饮食模式和饮食趋势。我们的重点一直是描述饮食随时间变化的方式，并确定这些趋势背后的一些主要因素。这项工作的复杂性使我们开发了许多独特的系统来对食物进行分类和评估饮食的整体质量。我们还解决了在衡量食品供应和食品相关行为随时间发生变化时存在的挑战。本文总结了与食物分类、总体饮食质量指数、趋势研究相关的一些方法学工作，以及我们在这一领域仍然面临的挑战。(C)1999年学术出版社。
Over the past 2 decades our group of nutrition and economics researchers at the University of North Carolina at Chapel Hill has used a wide array of methods to study eating patterns and dietary trends. Our focus has been on characterising the way diet has changed over time and identifying some of the major factors underlying these trends. The complexity of this undertaking has led us to develop a number of unique systems for classifying foods and assessing the overall quality of diet. We have also addressed the challenges that exist when measuring changes in both the food supply and food-related behaviors over time. This paper summarises some of the methodological work related to food grouping, overall diet quality indices, and trends research as well as the challenges we still face in this arena.
