Measuring dietary intakes of individuals is challenging due to random and systematic errors, with current methods including traditional approaches like food records and modern digital methods. The choice of assessment method is crucial and should consider various factors including research question, study design, and sample size. Despite the challenges, dietary assessment tools remain important for nutrition research and monitoring efforts.
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.
