Evaluation of Community Restaurants Linked to Government Food and Nutrition Safety Programs: A Scope Review

Community restaurants linked to government food and nutritional security programs are establishments created to offer meals to the population in socially vulnerable situations. The objective was to identify the methods, approaches, criteria, and indicators used to evaluate restaurants linked to government food and nutrition security programs. A scoping review based on the Joanna Briggs Institute’s methodology and the international guide’s recommendations of preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews was conducted. Medline databases via PubMed, Lilacs, Scopus, Cochrane, Web of Science, and ScienceDirect were used. Primary observational studies, systematic reviews and meta-analyses, ethnographies, documentary studies, and case studies were included, with a quantitative, qualitative, and/or mixed approach. A total of 2498 studies were identified. After taking out 180 duplicated articles, another 2202 articles were excluded by the title. Among the 71 studies selected for complete reading, 10 did not correlate with the research objective, and 12 were included after analyzing the references, totaling 73 included studies. In this review, evaluative approaches were mapped and systematized on the menu, food consumption, food health, food security and/or insecurity, nutritional education, and human right to adequate food; users’ profile and health, implantation, history, perceptions, senses, and meanings; handlers/workers; hygienic–sanitary quality; evaluation and monitoring; physical–functional planning, and rest–intake. The presented data provide elements that can be adapted in future evaluations and describe the panorama of academic production in this area.


Introduction
Community restaurants (CRs) linked to government food and nutrition security programs are world-renowned food and nutrition security establishments whose objective is the production and distribution of free or low-price meals for people in situations of social vulnerability in order to increase access to food and guarantee human rights to adequate food and fight hunger [1][2][3][4][5][6][7][8].
Several CR experiences can be found in countries such as Peru (Comedores Populares), Chile (Servicios de restaurantes populares), Spain (Comedores Sociales), Argentina (Comedores comunitarios), Canada (Community/collective kitchens), and Australia (Community Kitchens).Like community kitchens in Brazil, soup kitchens are located in countries such as Mexico, Peru, Uruguay, the United States of America, and Colombia [9].
The evaluation and monitoring of food and nutrition security are essential axes for programs and public policies to promote access to food.Through assessments, tools can be offered for improvement, management, and strengthening, especially regarding political and economic instability and threats to social rights.The evaluation must be a continuous and permanent object, aiming to reorient actions and subsidize public agents in decision making, interventions, and the implementation of public policies [10,11].
In this sense, there is an increase in investments by public agents in social program evaluations.However, evaluating food promotion programs is challenging due to the multiplicity of actions, multidisciplinary nature, heterogeneity of local and regional problems, and cultural and socioeconomic diversity [12].Therefore, evaluations must be developed with knowledge and practices that may be influenced by different approaches, scientific disciplines, and theoretical-methodological traditions, which can reveal relevant evidence for the program [13,14].
In addition, considering that health service managers need to monitor programs to obtain information on the daily decision-making process and that population surveys are carried out but not with the desired frequency, it is necessary to develop and improve approaches, techniques, and methods for evaluation based on data produced by health information systems [15].
Thus, systematizing findings from CR assessments aims to improve practices and policies so that researchers can identify possible gaps and understand how such researchers have conducted studies in this area.In this way, the scoping review can help produce new evidence when the existing scientific production is recent and/or incipient and examine how research is being developed in consolidated areas, which can generate knowledge with the potential to guide decisions and actions in public policies.
The present study aims to identify the methods, approaches, criteria, and indicators used to evaluate community restaurants linked to government food and nutrition security programs.

Protocol and Registration
This scoping review study aims to synthesize research evidence to map the literature on a previously determined subject (nature, characteristics, and volume), identifying knowledge gaps [16].This review had its study protocol registered in the Open Science Framework on 23 December 2022 (https://osf.io/eptfv,accessed on December 23,2022).The protocol was developed based on the recommendations of the international guide's preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) [17] and the Joanna Briggs Institute (JBI) method [18].
The structure consists of six main consecutive steps: (I) identification of the question and research objective; (II) identification of relevant studies that would enable the breadth and scope of the review's purposes; (III) study selection, according to predefined criteria; (IV) data mapping; (V) summarization of results, through a qualitative thematic analysis about the objective and question; (VI) presentation of results, identifying implications for policy, practice, or research.The acronym PCC-Population, Concept, and Context-was adopted with the following question: "What is the scientific evidence produced about the evaluation approaches carried out in community restaurants linked to governmental programs of Food and Nutrition Security?".Therefore, they were defined based on the guiding question: population-users (target audience), professionals, and managers involved in program evaluations; concept-methods, approaches, criteria, and indicators used and evaluation results; and context-community restaurants linked to government food and nutritional security programs.

Inclusion Criteria
This study included observational studies (cross-sectional, case-control, cohort, and ecological studies), documentary studies, and case studies, with a quantitative, qualitative, and/or mixed approach.There was no restriction regarding publication date, language, geographic region, or country.Also included were studies that addressed the methods, criteria, and indicators used in the evaluations of CRs, carried out with users of such restaurants, professionals, and/or managers who work in these food services where eligible.
CRs linked to government food and nutritional security programs were considered to be food services financed by the municipal, state, and federal government or with public funding such as community restaurants, comedores populares, comedores sociais, comedores comunitários, budget restaurants, economy restaurants, popular restaurant, community restaurants, government-subsidized kitchens, social kitchens, community kitchens, community food programs, soup kitchens, and self-service.These are programs that offer food to the population with social vulnerability.

Exclusion Criteria
Studies and publications whose research context was not exclusively the evaluation of CRs, reviews, editorials, comments, perspectives, conference abstracts, reports, opinion polls, master's theses, doctoral theses, or systematic or systematized reviews were excluded.Studies conducted in restaurants located at universities or private companies were also excluded.

Information Sources and Search Strategy
The last searches were conducted in June 2023 in the databases Medical Literature and Retrieval System online (Medline/via PubMed), Latin American and Caribbean Health Sciences Literature (Lilacs/via Virtual Health Library), Scopus, Cochrane, Web of Science, and ScienceDirect.
The descriptors and their synonyms were identified in the Medical Subject Headings (MeSH) and Health Sciences Descriptors (DeCS): "community restaurants", "comedores populares", "comedores sociais", "comedores comunitários", "budget restaurants", "economy restaurants", "popular restaurant", "community restaurants", "government-subsidized kitchens", "social kitchens", "community kitchens", "community food programs", and "soup kitchens".These were associated with the terms referring to the evaluation, that is, "evaluate", "assess", and "assessment".Along with the descriptors, the Boolean operators AND/OR were used to compose the search strategies in the databases.The strategy was specifically adapted to each database.The results were exported to the online reference manager EndNote ® , where duplicate references were excluded.After this step, the other documents were exported to Rayyan ® , where another evaluation of the duplicates was carried out, and the selection steps of phases I and II were carried out.

Data Selection and Extraction
Phase I was performed by two reviewers independently.Eligibility criteria were applied for selection by titles and abstracts.Then, in phase II, also carried out by two independent reviewers, the full texts were analyzed, again applying the adopted eligibility criteria.Also, the authors evaluated the list of references from the included studies.In phase II, the exclusions were justified.At all stages, disagreements were resolved in a consensus meeting.Contacts were made with experts to identify whether any study was left out of the search, as described in Figure 1.
The review results are presented in a descriptive format, using tables to summarize data from the studies, following the JBI recommendations [18].

Summary of Results
The results were synthesized by qualitative analysis, with information presented in narrative, tabular, and/or graphic form.The studies were evaluated by identifying the used methodologies and the prevalence of the methods, approaches, criteria, and indicators reported from the proportions based on the number of included studies.
In addition, the information was synthesized and subdivided into ten groups: user profile; users' health; handlers/workers; menu, food consumption and food health; hygienicsanitary quality; assessment of (in) food and nutrition security, nutrition education, and the human right to adequate food; implementation, history, perceptions, senses, and meanings; physical-functional planning; rest intake; evaluation and monitoring.The review results are presented in a descriptive format, using tables to summarize data from the studies, following the JBI recommendations [18].

Discussion
Community restaurants have been evaluated since the 1990s, initially seeking to describe the population that accessed these facilities, focusing on sociodemographic profiles and the reasons that led these users to frequent such spaces.After this initial period, other research aimed to evaluate the quality of the food served and its impact on the health of users and the situation of food insecurity.Studies have focused on evaluating community restaurant programs, shifting from looking at users to focusing on the program concerning achieving its objectives for society.
The main approach in the evaluations of the CR was the quantitative one, which is defined by the work carried out with variables expressed in the form of numerical data, which rigid resources and statistical techniques are used to classify and analyze, such as the percentage, mean, standard deviation, correlation coefficient, and regressions, among others.As they express greater precision and reliability, quantitative studies are more suitable for planning group actions, as their results are likely to be generalized, primarily when the surveyed samples faithfully represent the population from which they were taken.On the other hand, the qualitative approach seeks to understand specific complex phenomena of a social and cultural nature through descriptions, interpretations, and comparisons without considering their numerical aspects (mathematical and statistical rules) [85,86].
For this dichotomy to be overcome, some researchers seek mixed methods.The choice of quantitative, qualitative, or mixed studies is mainly based on the research questions and chosen variables.However, quantitative studies have been the most chosen option, not only to answer such research questions but mainly because such studies are used for the direct or indirect evaluation of food and nutritional security programs.Subsidies are offered when considering the maintenance of programs with indicators such as cost/benefits or compliance with the user profile to be covered by policies to overcome the population's social vulnerability.
As for the study design, the cross-sectional design is the most predominant.Compared to other designs, this type of study is easily carried out, fast, economical, and very useful in public health.In addition, it offers a better cost/benefit ratio for planning and evaluating public programs, as already mentioned.This study design analyzes well-defined populations, with its fundamental characteristic being the measurement at a single moment [85,86].However, such designs have limitations.In general, it is impossible to determine causality to ensure that confounding factors will be equally distributed between the groups, and there is no way to guarantee that they are not compromised by prevalence bias (cured and deceased people are excluded).Nevertheless, the sample's internal groups may have very different sizes, resulting in a loss of statistical efficiency.Still, its strengths outweigh its limitations [87].
Another type of study that stood out was the case studies, characterized as studies of a well-defined entity such as a program, an institution, an educational system, a person, some people, or a social unit.This study design seeks to understand in depth how and why a particular situation, which is supposed to be unique in many aspects, leads to such behavior.Therefore, it seeks to discover what is more important and characteristic about this object from the participants' point of view.It always intends to analyze the case objectively and pragmatically or present a global perspective of the event (case) [86,88].
Regarding the origin of the studies, Brazil, followed by the United States, gained greater prominence.This arises from the fact that Brazil currently has a well-structured program that offers meals, preferably to the low-income population, as part of the food assistance strategies integrated into the Brazilian federal government s network of social inclusion and hunger-fighting policies [7,26,65,67].The United States, due to its federalism model and regarding the preparation of the meals and the financing of these initiatives, presents state or municipal initiatives with the participation of the local government and volunteers.These initiatives are vital to the food security of the North American low-income community [5,89].
Observing the subdivisions adopted by this study, the evaluation of the served menu, food consumption, and dietary health were the most studied (20 studies).This fact comes from the researchers' concern for evaluating whether these restaurants, even offering the meal for free or at subsidized prices (USD 0.20 to 1.02), produce a quality meal that promotes users' health.To this end, they used dietary surveys through food history, which met the inclusion criterion of a frequency of meals no less than three times a week during the last six months.Obtaining data related to the users' dietary information included the technique of retrospective dietary assessment (35%), application of food frequency (25%), the 24 h recall (30%), and/or direct weighing of food [90][91][92][93][94]. Retrospective methods included the 24 h recall, food frequency questionnaires, and food history.When applying the recording method, the food and drinks consumed in the last 24 h were quantified, describing the type of food and drink, size and/or volume, preparation method, and fractionation.The food frequency consisted of applying a list of foods in which the interviewee indicated how often each food was consumed in a given period.The direct weighing of food consisted of a prospective method carried out by weighing the food discounting the inedible parts and leftovers.The various methods for the quantitative assessment of food consumption provide information not only on the meals consumed in the CR but also on how they contribute to the user's day and the coverage of nutritional needs.According to the Council of the Institute of Medicine, Food, and Nutrition, three consecutive days of assessment of food consumption is representative of an individual's diet.It constitutes the gold standard for obtaining data on the food consumption of individuals and/or populations [93].
For the food consumption investigation, part of the questionnaire for surveillance risk and protective factors for chronic diseases by telephone survey (VIGITEL) was used.VIGITEL is a Brazilian survey carried out by the Ministry of Health, created to monitor risk and protective factors for chronic non-communicable diseases in all capitals of the Brazilian states and in the federal district.Data collection is carried out through telephone calls to interviewees, and the questionnaire is composed of sociodemographic and health variables, providing information on the population's habits in relation to food, physical activity, smoking and the consumption of alcoholic beverages, and the existence of diseases such as diabetes, hypertension, and depression, among others [95], in addition to the offer of the total caloric value, the caloric density of the meal [40,96], regional food offer, the number of calories provided by dietary liquid protein [97], and macro and micronutrients [98,99], to verify if the daily supply of calories, protein, and nutrients is adequate.Although the methods used to determine consumption are highly different, the choice for a certain method was undoubtedly due to the cost/benefit ratio, not the precision.VIGITEL, for example, is an investigation carried out through telephone calls and, therefore, subject to biases inherent to the desirability and memory of individuals.
The nutritional composition of the meal (45% of the studies) was evaluated using technical preparation files [100], direct food weight, and food composition tables [101].Technical preparation files consist of an operational management support instrument, which aims to survey costs, order preparation, and calculate the nutritional value of the preparation to be carried out.They help support menu planning.Meal suitability values were compared to requirements specified by the Food and Drug Administration standards [101], Centers for Disease Control and Prevention [96], Food and Agriculture Organization of the United Nations [102], and National Health Surveillance Agency [97].The choice of these strategies that determine and evaluate consumption and adequacy were adopted, possibly because they can be replicated by subsequent studies and compared with national or international standards.
These studies aimed to assess the adequate supply of nutrients by restaurants.The studies indicated that meals served at the CR presented an energy density above the recommendations.However, these values can be justified because these restaurants have consumers that usually just have one meal a day, and this meal is consumed at the CR.Regarding the nutritional composition of the meals, the majority attended the nutritional needs for the lunch period, the most served meal at the CR.These studies aimed to assess the adequate supply of nutrients by restaurants.It is important to ensure the adequacy of the nutritional composition of menus, thus creating conditions for users to have a nutritionally healthy meal.
For the assessment of food safety/insecurity, in Brazil, there is the Brazilian Food Insecurity Scale [103].In the United States, the Nutritional Knowledge Scale, Central Food Safety Module was used [104], and in Mexico, the Latin American Food Security Scale [105].They all directly assess one of the dimensions of food and nutritional security in a population through the perception and experience of hunger.Hunger perception scales are direct indicators for assessing food insecurity but do not measure the nutritional dimension.Using the score obtained, the scales classify the assessed households into food security, mild food insecurity, moderate food insecurity, or severe food insecurity.They have become an assessment standard, as they can express food access and provide high reliability, reflecting the experience of life with food insecurity and hunger.
Nutrition education was developed through workshops, recreational activities, and focus groups to promote education for citizenship and create conditions for empowering the population regarding food and nutritional security issues and the right to food.This technique can be improved and transcribed to the local reality and culture.This allows for some instruments to be adjusted and validated in different countries and cultures, conducting studies resulting from applying such instruments, subject to comparison.In addition, a legal and institutional approach was used to evaluate the human right to adequate food, analyzing the limits and possibilities of the advances and preservation of the guarantee of the human right to adequate food [106].These studies aimed at developing active citizenship among restaurant users who participate in social programs, in which society mobilizes and can demand from public authorities the fulfillment of the right to adequate food from a legal point of view.
Profile studies of restaurant users (13 studies) aimed to characterize frequent users to verify whether they serve the population with higher rates of social vulnerabilities.The main sociodemographic indicators used in these assessments were gender, age group, marital status, skin color, education, head of household, family composition, place of residence, housing condition, type of housing material, profession, per capita income, social class, formal contract, place of work, possession of goods, means of transportation used, motivation for having the meal, days on which meals are served, place where meals are served on weekends, beneficiaries of social programs, drug or alcoholic beverage users, practice of physical activity, and the presence of chronic diseases.In Brazil, most studies used the Brazilian Institute of Public Opinion instrument as their basis, which is a pioneering study on the evaluation of user profiles [107].Carrying out this type of analysis enables a more detailed diagnosis of each region's socioeconomic inequalities and specificities, thus facilitating the planning and execution of corrective actions consistent with the local reality.Majorly, CR users are low-income, non-white race, and have little educational background.Therefore, CRs follow their goals to offer meals to the most vulnerable population.Food access to this population is essential since low-income people eat less or no food, and frequently, do not have resources to buy it.
In the evaluations of the users' health (12 studies), the studies aimed at evaluating whether the food served by the CR presented a connection with users' diseases such as metabolic syndrome, cardiovascular diseases, chronic non-transmissible diseases, anemia, total cholesterol, triglycerides, high-density lipoproteins (HDL), low-density lipoprotein (LDL), and very low high-density lipoprotein (VLDL) [96,[108][109][110] using methods already scientifically established by the WHO.Dyslipidemia, anemia, and blood glucose were measured in a fasting blood sample, and to determine glucose, total cholesterol, and triglycerides, enzymatic colorimetric methods were used.HDL was determined using the low-and very-low-density lipoprotein precipitation method using the cholesterol oxidase/peroxidase enzyme system with colorimetry.Blood pressure was measured twice with a properly calibrated aneroid sphygmomanometer.The concern in evaluating users' health arises from the low cost of the food, making it possible to have concerns about the quality of the final product served to the consumer.The recommendations of the World Health Organization and the International Diabetes Federation were used to assess nutritional status (41.6% of the studies).The studies evaluated the user's health to verify their current state of health and whether the food served by the restaurants had promoted the improvement of their health or the onset of diseases [98,108,110,111].The CR's primary objective is to serve low-cost food that is nutritionally healthy and does not harm the health of its guests.
Body mass index (BMI) and waist and abdominal circumference were also evaluated and correlated with the onset of health problems.To obtain the body mass index, the ratio of weight in kilograms to the square of height in meters (kg/m 2 ) was calculated, while circumference measurements were obtained using a measuring tape.This type of assessment seeks to recognize the users' dietary needs so that it is possible to intervene appropriately for health maintenance or recovery.The assessment of nutritional status through BMI is a good indicator of the accumulation of adipose tissue due to excess energy, and it is equally reliable for both genders and different ages.Other methods that could be used in this type of evaluation are densitometry and bioimpedance, which are quick, as they are performed in up to 12 min and do not require preparation.However, among the disadvantages are the high cost, the use of radiation during the evaluation, and the difficulty in transporting the equipment to different locations [112].
To evaluate the implementation, history, perceptions, senses, and meanings, the authors resorted to a sociohistorical analysis (41.6% of the 12 studies) [113,114], bibliographic research, documentary, and field research, and direct observation [115,116].They created focus groups with managers, handlers, and users, seeking to understand each person s life story and their perceptions about these food and nutrition establishments, which aim to provide access to food and fight hunger.However, this investigation method may not be as efficient in terms of the coverage of a specific topic compared to individual interviews because there is little depth on the subject.There is a possibility that members may not honestly express their personal opinions, especially if their ideas differ from those of other members [117].According to Sordini [118], for the users of these spaces, the main perception is that the practices, from preparing food to eating the meals served by the CR, are based on love, trust, and hope as a possibility of meeting with the others, and it implies a standard view of possible, desirable, and shared horizons of action.
Occupational psychosocial characteristics were studied using the Job Content Questionnaire (JCQ), a validated and self-administered instrument designed to measure workers' social and psychological characteristics.It is often used for the analysis of micro-level job characteristics, such as assessing the relative risks of individual exposures to different work settings, to predict the development of work-related illnesses, psychological distress, coronary heart disease, musculoskeletal diseases, and reproductive disorders [121].The food and nutritional security level of workers/handlers was also evaluated using the food insecurity scales [103][104][105].A questionnaire based on current Brazilian legislation on good handling practices (National Health Surveillance Agency) was applied to assess Brazilian food handlers' knowledge and self-reported practice in two studies [123,125].These studies served as a basis for revealing the characteristics of workers whose well-being is reflected in their health and their daily work practices.
Within the scope of the evaluation and monitoring studies, the construction of the proposal of the theoretical-logical model of Brazilian community restaurants was carried out [55] as a representation of the program and its movements and relationships, translating into theoretical and practical propositions for the evaluated object.A proposal for an assessment matrix was also developed [56] containing the restaurants' dimensions, sub-dimensions, and evaluation indicators with their respective justifications.To build the theoretical-logical model and matrix, an in-depth literature review and consensus workshops were carried out, totaling 12 h, using the traditional committee technique.The matrix was evaluated by experts external to the research group with experience in CR implementation and management.In addition, the criteria of efficiency and effectiveness were used to create a value judgment of CRs [14,126].To evaluate the effectiveness of the CR program, the proportion of coverage of the "target audience," defined within the scope of the CR program, was estimated.Access to food was considered adequate effectiveness when the CR, within their possibilities, served meals to 50% to 70% of users considered as the program's "target audience".Data envelopment analysis (DEA) was used as the most appropriate methodology for the efficiency of public spending.For this purpose, the software MaxDEA version 12.0 for data envelopment analysis was used.For the evaluation and monitoring of public policies and/or instruments, the authors resorted to evaluation techniques according to the criteria of effectiveness and efficiency, which are guidelines for the planning and improvement of programs in public management [113,127,128].
The assessment of the hygienic-sanitary quality was verified using the sanitary inspection script based on the Resolution RDC nº 216/2004 of the National Health Surveillance Agency [123], from the checklist of Manual de buenas practicas de manipulación de alimentos para restaurantes y servicios afines [129] and the Official Mexican Standard NOM-093-SSA1-1994 de Practicas de hijiene y sanidad en la preparación de alimentos que se ofrecen en establecimientos Àjos [130].They all aim to help traders and handlers prepare, store, and sell food appropriately, hygienically, and safely [123].The evaluations were aimed at verifying the quality of the hygienic-sanitary conditions and identifying non-conformities that could interfere with the quality of the served meals, calculating the adequacy percentage of the hygienic-sanitary conditions [131,132].These studies used standards and norms from the national legislation of each country.The main evaluated items were buildings, installations, furniture, and fixtures; the hygiene of facilities, equipment, furniture, and accessories; the integrated control of vectors and urban pests; water supply; waste management; handlers; raw materials, ingredients, and packaging; food preparation; the storage and transport of prepared foods; exposure to the consumption of prepared foods; documentation and records; standard operating procedures; and, finally, responsibility.For application in other countries, it is necessary to follow the guidelines and checklists approved by the national health surveillance agencies.In this sense, such instruments offer the possibility of determining which conditions are considered ideal for producing meals and which points require correction to obtain the ideal conditions.Furthermore, it is possible to analyze the conditions of restaurants in different countries after the required adaptations.
The physical-functional planning studies aimed to assist in the implementation of CRs.To this end, a list describing the equipment, utensils, and consumables by sector and their respective quantities was drawn up.It also describes the average cost of meals and base menu planning for five days (Monday to Friday).The analysis of the quantity of human resources necessary for the establishment's operation was used as a basis for the calculations, using several parameters described by Teixeira et al. (2007) [83].The organization chart of the staff was prepared, describing the positions and functions.Furthermore, when evaluating the installation of CRs, aspects related to location, zoning, sectors, and environment were observed based on the roadmap for the implementation of community restaurants published by the Ministry of Social Development and Fight against Hunger [133].The studies in this subdivision are Brazilian and followed the federal government's rules.The other studies did not assess physical-functional planning.
To determine the intake (consumption) of meals, the studies used the proportion between the food returned by users and the quantity of food distributed.By performing the calculation, the formula proposed by Vaz (2006) [84] was used to obtain the food waste index and was adopted in the evaluation of CRs.Thus, it was considered as a synonym of poor quality when the indexes were above the recommended percentages, which can be avoided through planning.This type of evaluation's main objective is to promote diners' awareness and minimize food waste.It should be noted that only two studies assessed this issue, one in Brazil and one in the United States.In both cases, the assessment of food losses was carried out using the same formula.It is crucial to raise awareness of the need to reduce waste as one of the strategies for the sustainability of restaurants.Food waste is one of the sustainability assessment pillars in restaurants [134].In this view, sustainable actions must be developed within the most diverse stages involving the meal production process, thus contributing to increasing the quality of the service provided and sustainability [135].
Systematizing and disseminating findings regarding CRs assessments can contribute to identifying the most prevalent state practices and policies, research gaps that may indicate which methods and tools should be created and consolidated, and how research in this area is being conducted.In this way, the scoping review can help the reviewer examine emerging evidence when the existing scientific production is recent and/or incipient and examine how research is being conducted in already consolidated areas that can generate knowledge with the potential to guide decisions and actions in public policy.
This study presents limitations inherent to systematic reviews, or not, such as, in some cases, not all studies are included in the main databases, and it does not propose, in the case of the scoping review, to evaluate the quality of the included studies.At the same time, materials and research that are not published in scientific journals and databases, such as government documents, are not included and could have provided more information about CRs.
The search used eight databases, allowing a greater number of studies in the evaluated area to be found.Accordingly, the review includes a variety of studies published since the 1990s on evaluations carried out on CRs, which allowed the identification of different evaluative approaches using quantitative, qualitative, and mixed methods, in addition to presenting remarkable experiences in several countries.

Conclusions
Seventy-three studies were published since the 1990s in different countries, mainly in Brazil.The evaluative approaches dealt with the menu, food consumption, food health, food security and/or insecurity, nutrition education, the human right to adequate food; user profile and health; implantation, history, perceptions, senses, and meanings; handlers/workers; hygienic-sanitary quality; evaluation and monitoring; physical-functional planning; and rest intake.The results increase the comprehension of evaluation methods performed at the CR.They provide details on methods, approaches, criteria, and indicators that can be used and/or adapted in future evaluations.The results also describe the area's academic production panorama.
In this scenario, progress on the methods, criteria, and indicators used in CRs is necessary to better investigate the nutritional and food security framework.The evaluations performed in these establishments must be strategies inherent to the programs, being fundamental for their qualification and goal achievement.
Furthermore, the scoping review is appropriate to examine studies for decision making in the theoretical-methodological field, from mapping theories to methodologies that should inform researchers.Systematizing and disseminating findings fulfill the objective of contributing to practices and policies.
