Qualitative evaluation of the menu and plate waste in public day care centers in São Paulo city, Brazil

Sustainability in food service: A systematic review

The irrational functioning of the food sector can negatively impact the environment and resources for future generations. The aim of this study is to analyse the assessment of sustainability indicators related to meal production processes and waste in the food service through a systematic literature review. The hypothesis is that these indicators are still little explored. This review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols. The databases consulted were Lilacs, Science Direct, Scientific Electronic Library Online (SciELO), Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, OpenGrey and Greylit. Six different search strategies were applied, combining the terms sustainability and food service, plus manual searches. The search took place until April 2020 and there was no language restriction of the studies. After removing duplicates, 770 publications were identified through the search process, with 44 having been included in this review. Most publications carried out the quantification of food waste (38/44), while in 7/44 there were questionnaires, checklists and water footprint assessments. Most studies identified high indicators of waste, as well as little awareness of sustainability. Factors such as controlled portioning, omnivorous menus and dissatisfaction with the menu were reported to have caused the greatest losses in the process. This review identified a restricted assessment of sustainability in food service, countering the need to deepen these indicators and the effect of meal production processes on sustainable development.

Identification and Evaluation of Tools Utilised for Measuring Food Provision in Childcare Centres and Primary Schools: A Systematic Review

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.

Food Waste and Qualitative Evaluation of Menus in Public University Canteens-Challenges and Opportunities

BACKGROUND

This study aims to evaluate food waste and menu quality in two canteens (A and B) from a Portuguese public university in order to identify challenges and opportunities to improve the food service.

METHODS

Food waste included the analysis of two canteens over 5 consecutive days by selective aggregate weighing. A qualitative evaluation of a 5-week menu cycle related to lunches was performed through the Qualitative Evaluation of Menus (AQE-d) method.

RESULTS

Both menus have "satisfactory" evaluations and lower adequacy to the dietary guidelines in criteria A, which evaluates general items from the dish, and in criteria B, which evaluates meat, fish and eggs. The calculated mean of food waste in both canteens exceeded the acceptable limit of 10%, except for the vegetarian (7.5%) dish in canteen A. The biggest waste was found in the vegetarian dish (16.8%) in canteen A. In meat dishes the conduit presents more waste (17.0%) than in fish and vegetarian dishes. Among these, the vegetables were the most wasted (25.3% and 27.9%, respectively).

CONCLUSION

This work presents some insights to future interventions in the direction of a healthier and more sustainable foodservice.

How Are School Menus Evaluated in Different Countries? A Systematic Review

School meals should focus on quality of life issues, particularly on reducing food shortages, overweight, obesity and its consequences. As an essential tool for quality assurance, creating the menu is an activity of great complexity and requires multidisciplinary knowledge. This activity covers the observation of countless aspects of quality, highlighting nutritional, sensory, cultural, hygienic, and sanitary issues, among others. This study aims to identify and analyze instruments and methods to evaluate school menus in different countries. The authors developed specific search strategies for Scopus, Web of Science, Science Direct, Pubmed, Lilacs, ProQuest Global, and Google Scholar. The included studies' methodological quality was assessed using the statistical analysis and meta-analysis review tool (MASTARI). A total of 16 cross-sectional studies met the inclusion criteria and were analyzed. Brazil and Spain were the countries that presented the highest number of studies (n = 5; 31.25% for each). The majority of the studies have a qualitative approach (n = 12, 75%), and only 25% (n = 4) of the studies present quantitative assessment methods to evaluate school menus. No school menu assessment tools were found to assess all aspects of menu planning. The results show a lack of a methodology or of instruments for evaluating the menus offered for school meals that can contribute to better dietary care offered to students.

Criteria adopted for school menu planning within the framework of the Brazilian School Feeding Program

ABSATRCT Objective This study aimed to investigate the main criteria used by nutritionists to plan school menus within the framework of the Brazilian National School Feeding Program. Methods Nutritionists from 21 municipalities in Southern Brazil were interviewed. Municipalities had between 20,000 and 70,000 inhabitants and were located in different mesoregions. Data were collected using an open-ended questionnaire and subjected to content analysis using NVivo® software. Results Sixteen criteria were identified, grouped into four categories: (1) food habits, culture, and acceptance; (2) nutritional characteristics; (3) food availability; and (4) management and execution. Brazilian National School Feeding Program regulations were recurrently cited within all identified categories, which demonstrates the influence of the program on nutritionists’ activities. Conclusion Brazilian National School Feeding Program regulatory guidelines for the development of school menus seem to influence the decision making of nutritionists. However, food purchase from family farms and calculation of meal nutritional value seem to be incipient criteria.

Influence of intervention on the menu's nutritional and sensory qualities and on the food waste of children's education center

The aim was to evaluate the influence of an intervention on the nutritional and sensory quality of the menus and on the food waste of a Children's Educational Center. It is a quasi-experimental study that used the Qualitative Assessment of the Menu Preparations method and performed the waste-ingestion quantities and clean leftovers. The intervention was characterized by the inclusion of new recipes and adequacy of portions according to recommendations for the children's age group. Data were analyzed using the Mann Whitney test with a significance level of p < 0.05. The intervention resulted in a reduction in the occurrence of the side dish supply, color monotony, presence of sweets, presence of fried foods, sweets associated with fried foods, and repetition of the main dish cooking technique. In addition, there was a significant reduction in the average quantities of waste-ingestion/child (from 69.02 ± 11.87g to 37.06 ± 15.57g), clean leftovers /child (from 161.47 ± 44.12g to 35.23 ± 33.73 g) and clean leftovers percentage (from 39.56 ± 7.96 to 21.01 ± 17.15). The positive influence of intervention reinforces the importance of adjustments in recipes and portioning of preparations to meet the nutritional recommendations and to control food waste.

[Nutritional adequacy and food waste in Early Childhood Education Centers]

Analyzing quantitative and qualitative aspects of school meals represents the initial stage to ensure that the National School Food Program (PNAE) is an effective space for the promotion of healthy eating habits and establishing individual rights. The objective of this study was to evaluate the nutritional adequacy of meals served and consumed, as well as quantifying food waste in Child Daycare Centers in Maceió, in the state of Alagoas. All meals served and consumed by 359 children (aged 17 to 63 months) were analyzed by the direct weighing method for three non-consecutive days in all institutions. Food waste was determined by the leftover factor and the nutritional value of meals served and consumed was compared to the PNAE reference values regarding energy, carbohydrates, protein, lipids, vitamins A and C, iron, calcium, zinc, magnesium and fiber. Of the 85 meals/preparations featured on the menu, 58 (68%) revealed a high leftover percentage; in excess of 10%. The meals served and consumed met approximately 50% of the recommended energy and macronutrient values. The difference between the averages of the nutrients offered and consumed was statistically significant (p < 0.05) for fiber, vitamin A, vitamin C, calcium, iron and zinc.

School menus in Santa Catarina: Evaluation with respect to the National School Food Program regulations

OBJECTIVE: To assess compliance of school menu planning with the National School Food Program's regulations. METHODS: This cross-sectional study analyzed 133 menus for 542 schools in 49 municipalities of the state of Santa Catarina. The menus were assessed according to the National School Food Program's regulations, the "Dietary Guidelines for the Brazilian Population" and the "Qualitative Evaluation of Menu Components for Schools". The data were analyzed by descriptive statistics. RESULTS: Nearly all (98.5%) municipalities met the requirement of technical responsibility for menu development and 81.0% acquired foods from family farms. The menus contained fruits (87.2%) and non-starchy vegetables (94.0%), but the frequencies of fruits and non-starchy vegetables were smaller than two to three times a week. The most common high-sodium and high-fat foods were commercially processed meats (53.0%), but their frequency was smaller than once a week. Likewise, the frequencies of beverages (natural fruit juice, coffee, and tea) were smaller than once a week. Most menus (85.1%) repeated foods during the week, and only 3.0% of the menus listed organic foods. CONCLUSION: Some school menus from Santa Catarina need to be revised with respect to the frequency of fruits and non-starchy vegetables, high-sugar foods, high-sodium foods, and high-fat foods, and need to increase food diversity and variety.
