Volume 1, issue 3 (2023): Special issue on Food Acquisition Research and Methods
High-quality food data collected from consumption and expenditure surveys are essential for researchers and policy makers to better understand trends in social, economic, and human development. Over the last decade, food surveys have faced challenges to sustain high data quality, including declining response rates and increasing respondent burden. At the same time, new opportunities around the use of new technologies and alternative data sources have emerged. This special issue presents recent methodological advancements in the collection of food survey data that contribute to research about increasing and sustaining data quality in such surveys.
Exploring Optical Character Recognition (OCR) as a Method of Capturing Data from Food-Purchase ReceiptsSpecial issue
This paper explores capturing expenditure data from food-purchase receipts using optical character recognition (OCR). Point-of-sale receipts provide means to assess the accuracy of self-reported expenditures by providing a comprehensive record of the number of items purchased and their prices. However, comprehensively coding receipts can be cost prohibitive, particularly for large-scale surveys. The burden of capturing [...]

Review of Food Diaries Used to Collect Food Acquisition DataSpecial issue
Food data are important for policymakers and researchers to understand food acquisition and expenditure, nutrition, food environments, food assistance, and so on. However, the collection of food data by asking people to recall their food acquisition is challenging for respondents sampled from a general population due to faulty memory, the burden associated with responding in [...]

Secondary Activities: Their Proximity to Primary Activities and Their Importance for Understanding Reports of Preparing and Consuming MealsSpecial issue
Time spent preparing and consuming meals is tracked closely by the USDA, and a growing literature shows how such time use relates to health and other important outcomes. Research has yet to consider the importance of assessing the relative sequencing of such production and consumption, potentially leading to inaccurate interpretations. We investigate this possibility and [...]

Usability of Augmented-Reality Portion Estimators During 24-hour Dietary Recall InterviewsSpecial issue
Dietary recall instruments are structured interviews that capture information on foods and beverages consumed by participants in the past 24 hours. These instruments often rely on tools to help estimate portion size such as three-dimensional food models or two-dimensional images in a booklet or on a computer screen. Two-dimensional tools are good alternatives to bulky [...]
