“…At a service level, the aggregated plate waste method is considered more suitable for food provision studies compared to the individual plate waste method [ 129 ], where total amount of food consumed is calculated by deducting the total amount of food wasted from the total amount of food served (as average portions) and dividing this by the number of children. A validation study by Chapman et al [ 130 ] found good agreement between individual and aggregated plate waste methods; however, both plate waste methods potentially underestimated vegetable consumption as some menu items, such as sandwich fillings, were not measured separately [ 129 ]. There is potential to combine aggregated plate waste with Sambell et al’s method [ 36 ] to get an accurate measure at service level of food served, consumed, and wasted, but this will require further research and validation.…”

Background: Children aged 2–11 years spend significant hours per week in early childhood education and care (ECEC) and primary schools. Whilst considered important environments to influence children’s food intake, there is heterogeneity in the tools utilised to assess food provision in these settings. This systematic review aimed to identify and evaluate tools used to measure food provision in ECEC and primary schools. Methods: The Preferred Reporting Items for Systematic Reviews (PRISMA) was followed. Publications (2003–2020) that implemented, validated, or developed measurement tools to assess food provision within ECEC or primary schools were included. Two reviewers extracted and evaluated studies, cross checked by a third reviewer and verified by all authors. The Academy of Nutrition and Dietetics Quality Criteria Checklist (QCC) was used to critically appraise each study. Results: Eighty-two studies were included in the review. Seven measurement tools were identified, namely, Menu review; Observation; Weighed food protocol; Questionnaire/survey; Digital photography; Quick menu audit; and Web-based menu assessment. An evidence-based evaluation was conducted for each tool. Conclusions: The weighed food protocol was found to be the most popular and accurate measurement tool to assess individual-level intake. Future research is recommended to develop and validate a tool to assess service-level food provision.

“…Dietary assessments in children pose unique challenges, including potentially limitations in children's concepts of time, food recognition and knowledge of preparation methods, ability to quantify estimated portion sizes, motivation, literacy, memory capabilities, and concentration spans (1, 19, 20). Objective measures of dietary assessments, such as plate-waste studies (21, 22), remote food photography (23), or the use of biospecimens (24, 25) (i.e., serum plasma carotenoids), may have lower potential for reporting biases, compared to subjective measures such as FFQs and 24hDR. However, objective methodologies have their limitations, often being burdensome, time-consuming, or unfeasible in large-scale or school-based data collection.…”

Background The purpose of this study was to expand the School Physical Activity and Nutrition questionnaire to include a greater variety of vegetables and to evaluate the relative validity and reliability of these revised items. Objectives This study utilized 2 convenience samples of third to fifth graders for an analysis: validity (n = 70) and reliability (n = 76). Validity was assessed by comparing questionnaire items with vegetable intake reported from a 24-hour dietary recall covering the same reference period. Reliability estimates were assessed via same-day test-retest. Results Agreement correlations ranged from 0.35 to 0.71. Kappa statistics varied from 0.16 to 0.66. Percentage agreements ranged from 57% to 87%. Test-retest Spearman coefficients were greater than 0.50 for 6 items, weighted Kappa values were greater than 0.40 for all 7 items, and percentage agreement exceeded 75% for 5 items. Conclusions Results suggest that the questionnaire is a valid and reliable measure of the previous day's vegetable intake in third- to fifth-grade students. This trial was registered at ClinicalTrials.gov as NCT02668744.

“…Taylor et al found that digital imaging was highly reliable in assessing children's consumption of fruits and vegetables during the school lunch period and that this method could significantly reduce the time and labor costs required to measure food waste levels with essentially no change in the precision of the measurements [37]. Chapman et al found that categorizing wasted food and then measuring the weight of wasted food in each category provided a better estimate of the weight of food wasted on individual plates [38]. Malefors et al developed and used a new automated waste quantification tool to more accurately quantify the level of student food waste, with a 10% increase in accuracy over traditional measurements [39].…”

Reducing food waste in the student population is important for promoting sustainable economic, social, and ecological development. In this paper, with the help of CiteSpace software (versions 6.1.R6 and 6.2.R4), we visually analyze the literature related to the food waste of students in the WoS core collection database. It is found that (1) scholars are paying increasing attention to the field of student food waste research, with the United States being the country with the largest total amount of research in this field, the greatest academic influence, and the most frequent cooperation with other countries. (2) Research in this field can be broadly divided into three phases: the starting period (2000–2010), the exploration period (2011–2015), and the development period (2016–2023). The research on student food waste involves multiple fields of knowledge, such as statistics, behavior, psychology, management, nutrition, etc. It is divided into three research hotspots, namely student food waste quantity measurement, student food waste influencing factors, and student food waste behavioral interventions, as well as three cutting-edge themes, namely student food waste in developing countries, student food waste and dietary intake and nutritional health, and student food waste from the perspective of behavioral science. (3) Scholars from different countries/regions have different research focuses. Research in the United States focuses on the development of student food waste interventions and the investigation of students’ and teachers’ knowledge, attitudes, and barriers to intervention in student populations; European scholars focus on researching this area from a behavioral perspective; developing countries in Asia focus on quantifying the level of food waste among college students and exploring the impact of demographic factors on student food waste; and developed countries in Asia focus on surveys of teachers, dietitians, and other parties to explore the impact of food education on food waste and propose food education interventions based on the recommendations of various parties. Based on the above findings, future research directions are proposed to provide references for subsequent research on food waste among students.
