Self-report methods of dietary assessment, including food records, 24-hour recalls, and food frequency questionnaires (FFQs) have been in widespread use for decades. It has been shown, however, that results from self-report methods are subject to reporting bias, and therefore can lead to spurious relationships between diet and health outcomes, and incorrect conclusions. More recently, objective methods of dietary assessment have been developed and are becoming more widely available. These newer methods offer an opportunity to overcome the problems associated with self-reported dietary intake and have the potential to instill greater confidence in the conclusions drawn about diet-disease and diet-health relationships.
The goal of this Article Collection is to bring together and highlight recent research on objective methods for dietary assessment, and stimulate further research to advance the development and use of these objective methods more widely.
This article collection can include studies on the development and use of biochemical markers of dietary intake (e.g. recovery, predictive, and concentration biomarkers; metabolomics indicators of nutrient intake, food and food group intake, and dietary pattern; wearable devices including sensors and/or cameras for sensing or photographing food intake; mobile technologies for recording food intake (which contains an element of objectivity) or other innovative technologies for improving dietary assessment).
We invite manuscript submissions including, but not limited to, the following areas:
• Development of objective dietary assessment instruments;
• Validation studies on objective methods, or objective methods combined with self-report methods to improve the accuracy of estimates of dietary intake;
• Validation studies of self-report methods against objective methods;
• Application and use of objective methods in epidemiological studies;
• Narrative reviews, systematic reviews, and meta-analyses offering novel information and unique perspectives on objective methods for assessing dietary intake;
• Advancements or new uses in objective methodology, with application to populations in which dietary intake can be particularly difficult to assess or for which few studies have been conducted (e.g. infants and young children, diverse populations, low-and-middle-income countries, elderly, etc.).
