We agree with Murphy and O ’Connor that alignment of dietary assessment tools with the purposes, populations, and settings to which they are applied and an evidence-based understanding of tools’ strengths and limitations are crucial to support appropriate use and interpretation.1,2 As recognized by Murphy and O’Connor, each administration of a short-term tool, such as a 24-hour recall or food record, captures intake on a single day, or a small number of days in the case of multiple-day records. With repeat administrations and the application of statistical methods,3 data from these tools can be used to estimate di stributions of usual intake in both surveillance and epidemiologic research.
