Measuring the dietary intakes of individuals for research and monitoring purposes is notoriously challenging and is subject to both random and systematic measurement error. In this review, the strengths and limitations of current methods to assess dietary and supplemental exposures are described. Traditional methods of dietary assessment include food records, food frequency questionnaires, 24-hour recalls, and screening tools; digital and mobile methods that leverage technology are available for these traditional methods. Ultimately, the choice of assessment method is dependent upon the research question, the study design, sample characteristics, and the size of the sample, to name just a few. Despite their challenges, dietary assessment tools are an important dimension of nutrition research and monitoring.
测量个体的饮食摄入量用于研究和监测目的是出了名的具有挑战性的，并且容易受到随机和系统测量误差的影响。在这篇综述中，描述了评估饮食和补充暴露的当前方法的优缺点。传统的饮食评估方法包括食物记录、食物频率问卷、24 小时回顾和筛选工具；这些传统方法都有数字化和移动技术的应用。最终，评估方法的选择取决于研究问题、研究设计、样本特征以及样本量等因素。尽管存在挑战，但饮食评估工具是营养研究和监测的一个重要方面。
