RESUMO

Worldwide, there is an increasing demand for plant-based food due to sustainable, health, ethical, religious, philosophical, and economic reasons. In Brazil, 14% of the population declares themselves vegetarians, and a noticeable increase in the consumption of vegan products is also noted. Substitution of animal dairy and egg is challenging from both sensory and nutritional aspects. Yet, there are no data regarding the nutritional value and ingredients of Brazilian commercial dairy and egg substitutes. Therefore, this study aimed to analyze the nutritional composition and used ingredients in Brazilian commercial vegan alternatives to dairy and eggs to provide information for Brazilian consumers of these products. A cross-sectional quantitative study was carried out in three steps: (i) sample mapping. (ii) data collection, and (iii) statistical analysis. A total of 152 samples were included. No differences were found between the energy value and total fat of vegan products and their animal counterparts. Vegan products showed higher amounts of carbohydrates and dietary fiber, and only the vegan versions of beverages and cheeses showed less protein than their counterparts. Cashews, rice, coconut, and soy were the most used ingredients in dairy substitutes. Emulsions of oil, starch, and isolated protein were used in vegan egg products. Most vegan beverages presented sugar in their composition. Vegan alternatives of dairy and eggs might be suitable for substituting their animal counterparts, but given that traditional versions of cheeses and milk are sources of protein in omnivorous diets, for equivalent nutritional replacement in vegan products, it is necessary to improve the protein content of their vegan counterparts.

RESUMO

This cross-sectional study aimed to identify factors that interfere with the adoption of good hygiene practices in public school food services (SFS) in Bahia, Brazil. The search was conducted in public schools in Bahia/Brazil. Data collection included (i) evaluation of the adoption of Good Practices in school food services through visual observation and registration in the checklist in Good Hygienic Practices in School Food Services; (ii) Identification of schools' foodservice physical areas and environmental comfort measures; (iii) identification of sociodemographic and occupational characteristics and assessment of attitudes and level of knowledge in food hygiene. The minimum sample of 158 schools (confidence level of 95% and an error of 5%) was stratified considering the total number of districts (areas) and the schools' number per area. The data were analyzed using the Statistical Package for Science-SPSS® in version 26.0. The categorical variables were described as frequencies and percentages, and the quantitative variables as mean and standard deviation. Chi-square, Kruskal-Wallis with Tukey's post-hoc tests were used to examine qualitative variables. Independent Student t-test and ANOVA with Tukey's post-hoc tests were used to examine quantitative variables. Categorical variables were evaluated by Pearson Chi-squared tests. The Pearson test was used to analyze the correlation between Attitude and knowledge. The classification of the sanitary status was of moderate risk in 74.8% (n = 119) of the SFS (51-75% of compliance) and 25.2% (n = 40) at high risk (26-50% compliance). The average percentage of compliance for the 159 SFS in the municipality was 50.23%, obtaining a high-risk classification (26-50% compliance). In the SFS, the absence of dry goods' storage, meat preparation area, and storage of residues in more than 98% of schools was observed. Accessing attitudes, 1.4% (n = 2) of the food handlers were classified as unsatisfactory (0 to 49% of correct answers), 8.5% (n = 12) as satisfactory with restriction (50-69% of correct answers) and 90.1% (n = 128) as satisfactory. There was no correlation between Attitude and Knowledge level (p = 0.394). Considering the knowledge level, the item with the highest and lowest number of hits were: "To avoid food contamination, I wash and disinfect my hands before preparing food" and "Contaminated food will always have some change in color, smell, or taste". There was a significant difference in the level of knowledge considering mean wage (p = 0.000), time working in school food service (p = 0.001), weekly workday (p = 0.000), and participation in food hygiene training (p = 0.000). Therefore, factors that interfered in adopting good practices in the SFS were: inadequate physical structure, absence of areas in the SFS, and absence/low number of equipment to control the production process in the cold and hot chain. Food handlers showed satisfactory attitudes and level of knowledge. However, the physical structure of the SFS compromises the adoption of good practices. It risks the safety of the food served to students at the evaluated public schools.

RESUMO

This study aimed to evaluate the association between the years of work of food handlers in the foodservice and excess weight among Brazilian low-income food handlers. A total of 559 food handlers from all Brazilian regions were characterized using a questionnaire. Weight and height were measured to estimate the Body Mass Index and classify the individuals. The association between food handlers' years of work in the foodservice, anthropometric status, and other variables (gender, age group, educational level, participation in a government program and per capita income at home and energetic consumption) were performed using Pearson's chi-square test (p < 0.05). Multinomial logistic regression analyses were performed (p < 0.05) as well as sensitivity tests using the outcome continuously and transformed, excluding underweight individuals, in a multivariate linear regression model. Most of the sample was female (63.1%), aged between 21 and 40 years old (63.5%), and 53.3% had studied up to complete elementary school. Almost 41% of the food handlers had less than half the minimum wage per capita income. Of the evaluated individuals, 59.9% presented excess weight. There was an association with family per capita income (Odds Ratio - OR: 1.73; Confidence interval - CI95%: 1.09-2.75); handlers whose per capita income was ≤0.5 minimum wage had a 73% higher chance of obesity than those with higher income. Working in foodservive ≥3 years increased the chance of being overweight by 96% compared to those who work for <3 years (OR: 1.96; CI95%: 1.11-3.49). No significant association was found between the years of work of food handlers in the foodservice and obesity. Since work-related factors may contribute to the high prevalence of excess weight, including working in a food handling environment, the government and employers should consider workplace interventions. These would guide the food handlers in avoiding high rates of excess weight and their consequences on public health. Excess weight is an important driver of costs in the workplace associated with absenteeism, job change, and diseases. More studies are necessary to clarify the relationship between the factors related to work and the anthropometric status of food handlers since excess weight is multifactorial.

RESUMO

Proteins are essential components in human nutrition, and animal products are usually the primary sources of human ingestion. However, the number of adherents to vegetarian and vegan diets has grown significantly, highlighting the need for alternatives to replace animal proteins. Meat substitutes aim to mimic the nutritional value and sensory characteristics of meat. However, studies suggest differences in their composition. This study is the first to evaluate Brazilian meat substitutes' nutritional quality and ingredients. A quantitative cross-sectional survey was performed in three steps: (i) Sample mapping of products commercialized nationwide; (ii) Ingredients and nutritional data collection and classification; (iii) Statistical analysis. One hundred twenty-five meat substitutes were included and described. The primary protein sources were soy, gluten, and pea protein ingredients. Vegan meat substitutes presented similar energy and protein values, with few exceptions among samples, with vegan canned fish alternatives presenting less protein than their counterparts. Overall vegan products did not differ regarding sodium levels but showed high amounts to compose a lunch or dinner meal. Vegan meat substitutes showed higher carbohydrates, dietary fiber concentrations, and few differences regarding total and saturated fat. Vegan meat substitutes may contribute to the adherence and maintenance of vegan and vegetarian diets. However, future studies about the implemented ingredients are needed.

RESUMO

Food service work is hazardous due to the intense rhythm of food production, and the working conditions can cause discomfort, fatigue, and occupational accidents and illnesses. For the perception of exposure to occupational hazards, workers must participate in continuing education programs. This study aimed to verify the perception and exposure to occupational risks at school food services (SFS) in Bahia, Brazil. This cross-sectional study was conducted in SFS from public schools in Bahia/Brazil. Researchers identified sociodemographic variables, occupational characteristics, and the Perception of Exposure to Occupational Risks by SFS food handlers. Also, anthropometric assessment (weight, height, and waist circumference), the presence of comorbidities, and the identification of exposure to occupational risks and measures of environmental comfort were evaluated. Most workers were female (98.6%; n = 140), mean age of 46.85 y/o, working as SFS food handlers between 1 and 5 years (50.7%; n = 72) but with no training on occupational risks (52.8%; n = 75). This lack of training is not associated with demographic or other occupational variables. The majority of the food handlers present a fair or good perception of exposure to occupational risk. These food handlers are also mostly overweight, and higher BMI was associated with hypertension and edema. The SFS were classified as of high occupational risk (mean of 31.24% of adequacy) environments. Ergonomic Risks had the lowest percentage of adequacy (7.69%, very high risk) regarding occupational risks, followed by chemical risks (31.5% of adequacy, high risk), accident risk (32.19%, high risk), and physical risk (36.89%, high risk). The excess of activities associated with precarious physical structure, insufficient number of equipment and utensils (in inadequate conservation) favors the exposure to occupational risk in SFS.

RESUMO

Eating Competence (EC) is one behavioral perspective of eating practices that has been associated with a healthy lifestyle. It emphasizes eating pleasure, self-regulation of eating, body weight satisfaction, and regular meal frequency that includes food variety without focusing on dietary guidelines. EC is composed of four components (Eating Attitude, Food Acceptance, Internal Regulation, and Contextual Skill), and its assessment is performed using the Eating Competence Satter Inventory (ecSI2.0™), developed and validated in English for an adult population. EC has been associated with diet quality and health indicators for various population groups and the development of skills that increase EC might be a strategy to improve nutritional health, and prevent obesity and other chronic diseases. In this sense, this study presents an overview of the background, concepts, features, and possible associations among EC, food consumption, and health outcomes. The high prevalence of diseases associated with food/nutrition draws attention to the necessity to broaden the view on food and its relationship with health and well-being, considering not only nutrients and food combinations but also the behavioral dimensions of eating practices. Healthy nutritional recommendations that take into account attitudes and behaviors are in accordance with the EC behavioral model. Studies on eating behavior emphasize the need to better understand attitudes towards food and eating in the general population using validated instruments. In this context, measuring EC and its association with health outcomes seems to be relevant to nutritional health. The complexity of food choices has been examined in social, behavioral, and biological sciences, representing a great challenge for applying unique and simple theoretical models. Multiple methods are required, as no single theory can fully explain food selection.

RESUMO

Meat is a source of protein widely consumed by the population in many countries due mainly to the nutritional aspects, sensory characteristics, and cultural aspects. The meat cooking preparation can promote significant changes in the meat's chemical composition and physical characteristics. Such transformations can impact both the acceptance of the product and consumers' health. Due to the different thermal processes altering the physical-chemical characteristics of meat, the present study aimed to evaluate the physicochemical characteristics of fillet steak submitted to different cooking methods: pan-frying with and without oil and air fryer. We performed the analysis to evaluate the physicochemical characteristics considering moisture, lipid, protein, ash, sodium, and potassium content, cooking loss index and colorimetry in three degrees of doneness of the meat, rare, medium, and well done. The fillet steak prepared by pan-frying with oil lost higher moisture and weight than the other samples. The air fryer method presented the highest moisture content. There was a significant difference in lipid content in which the pan-frying with oil fillet steak showed the highest amount of lipids. The pan-frying with oil steak fillet also presented more changes in the colorimetric parameters evaluated compared to the other samples. The pan-frying with oil cooking method promoted more pronounced changes in the steak fillet, and the cooking air fryer, the changes in meat quality are less pronounced. Therefore, the air fryer can be considered a good alternative for cooking meat.

RESUMO

This study systematically reviewed the relationship between occupational risks and quality of life (QoL) and quality of work life (QWL) in hospitals. A systematic review was performed according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guide, and the protocol was submitted on the PROSPERO website (CRD 2019127865). The last search was performed in June 2021 by two independent reviewers in the main databases, a gray literature database, and a manual search (LILACS, MEDLINE/PubMed, PsycINFO, CINAHL, Scopus, Embase, Brazilian Digital Library of Theses and Dissertations, Ovid). As eligibility criteria, we included observational studies, with adult hospital workers, with no restrictions on date and language, any type of instrument to assess QoL and QWL, any definition of QoL and QWL, and studies that presented the relationship between exposure and outcome. Newcastle-Ottawa was used to assess the methodological quality and RTI-Item Bank to assess the risk of bias. Given the impossibility of performing a meta-analysis, a qualitative synthesis was used to present the results. Thus, 11 studies met the criteria and were included in the review, with 6923 individuals aged 18 to 64 years. The studies were mainly carried out with health professionals (81.81%), women (63.60%), and in Asian countries (63.63%). All studies used different instruments and ways to categorize the QoL and QWL, and occupational risks. Only one study assessed occupational noise and another the ergonomic risk. All of them presented a relationship between occupational risk and quality of work life. They pointed to the need for measures to improve the lives of these professionals in the work environment. Therefore, studies show a relationship between occupational risks (noise, ergonomics, and stress) and workers' perception of low or moderate quality of work life. However, more homogeneous studies are necessary for instruments, conceptualization, and categorization of quality of work life.

RESUMO

Vegetable consumption is associated with increased health benefits, and vegetables are consumed both in cooked form and raw form in salads. All cooking techniques cause changes in a vegetable's the nutrient content. Consumers are increasingly health-conscious and have less time to prepare meals, and they do not know which cooking times and cooking methods are best suited to preserve the nutrients. This study aimed to determine the best method of cooking vegetables to maintain minerals (potassium and sodium) and carotenoids. The studied vegetables were broccoli (Brassica oleracea, var. Italica), carrots (Daucus carota), and zucchini (Cucurbita moschata). The cooking methods were: boiling, steaming, combined oven, microwave steaming, and microwave cooking. Samples of organic and conventionally grown vegetables were prepared in triplicate. Samples were analyzed to determine the availability of target minerals and carotenoids in the raw food and in each recommended cooking situation according to technical standards. Only the carrot showed a higher concentration in organic cultivation for carotenoids in raw vegetables, with both zucchini and broccoli having higher concentrations when grown by conventional cultivation. The zucchini from organic cultivation presented a reduction of potassium and sodium, almost consistently, in all cooking techniques. Regarding the conventionally cultivated zucchini, potassium remained stable in boiling. Broccoli from organic and conventional cultivation showed similar potassium levels for boiling and traditional steam cooking. Organic carrots showed easier sodium extraction compared with conventional cultivation. Heat treatment, in general, improves the accessibility of carotenoids.

RESUMO

Health emergencies such as the COVID-19 pandemic can negatively impact quality of life (QoL) due to higher levels of stress, social isolation, and uncertainties. In this scenario, distinct population groups might react differently. Vegetarians, who follow a non-conventional dietary pattern, could be more vulnerable to the abrupt changes in normal life routine and economic instability. Therefore, this study aimed at evaluating if the current pandemic situation somehow affected vegetarians' QoL. A cross-sectional study was carried out in Brazil between 28 July and 14 September 2020 to evaluate the QoL in vegetarians during the pandemic period. Vegetarian adults replied to an online survey that included the VEGQOL and WHOQOL-BREF instruments to evaluate QoL and questions related to the COVID-19 pandemic. A total of 1282 individuals participated. Only 3.8% had tested positive for COVID-19, but 39.9% affirmed having a family member who tested positive for the disease. Almost half (46.3%) of the sample had an income drop due to the pandemic. Results of QoL scores in the different subcategories of vegetarians were similar to previously published data. Individuals who had already tested positive for COVID-19 had lower QoL scores than those who did not test positive, but only in the VEGQOL. QoL was lower for the participants who declared that Sars-Cov-2 had already infected a family member for almost all the parameters evaluated. On the other hand, an income drop affected QoL only partially. Studying how vegetarians are influenced by such conditions contributes to the generation of relevant data that can be used to support healthcare and public policies in the future.
