A major methodological problem is dietary intake research is the specification of an adequate sampling design. Ethnographic research provides the investigator with essential data for more effective research design by establishing sources of temporal variation in food intake and by identifying significant consumption settings and main sociocultural characteristics affecting intracommunity differences in foot intake. A checklist of sources of temporal variation commonly found in various societies is presented as a guide for ethnographic work. Other uses of ethnography to improve dietary intake methodology are the identification of culturally and socially sensitive aspects of food use and the provision of background information for the interpretation of research results.
饮食摄入研究中的一个主要方法学问题是确定适当的抽样设计。人种志研究通过确定食物摄入的时间变化来源、识别重要的消费场景以及影响社区内食物摄入差异的主要社会文化特征，为研究者提供重要数据，以进行更有效的研究设计。文中列出了在各种社会中常见的时间变化来源清单，作为人种志研究工作的指南。人种志在改进饮食摄入方法学方面的其他用途包括识别食物使用中文化和社会敏感的方面，以及为解释研究结果提供背景信息。
