Introduction: Healthy eating habits and cooking skills can contribute to the treatment of type 2 diabetes mellitus (T2DM). Objective: This study aimed to adapt, test, and qualitatively evaluate the sensory characteristics of food recipes for their application in a culinary intervention program for individuals with type 2 diabetes, called Nutrition and Culinary in the Kitchen. Methods: Nutrition and Culinary in the Kitchen is an intervention program with hands-on cooking classes focused on promoting cooking skills. Recipes' modifications were based on the glycemic index of ingredients, then tested and discussed by nutrition experts in consensus workshops. Individuals with type 2 diabetes assessed and discussed the sensory characteristics of recipes in focus groups. Results: Recipes adaptations to suit type 2 diabetes population included replacement of rice by cauliflower and pasta by zucchini, and the use of fruits and spices in sweet recipes instead of using added sugar ingredients and/or non-caloric sweeteners. Those changes were positively accepted by the individuals with type 2 diabetes. Conclusion: The adapted culinary recipes can be used in dietary guidelines and in cooking interventions to promote eating habits that contribute to glycemic control.

Use of the term whole grain on the label of processed and ultra-processed foods based on cereals and pseudocereals in Brazil.

There has been an increasing consumption of processed and ultra-processed foods, accompanied by growing concerns about the relationship between diet quality and health. Whole-grain foods, composed of cereals and pseudocereals, are recommended as part of a healthy diet, and food labeling is an important tool for consumers to identify the presence of whole grains in packaged foods. This study aimed to analyze the use of the term whole grain on the label of processed and ultra-processed foods based on cereals and pseudocereals (amaranth, quinoa, and buckwheat) in Brazil. Data were collected by a census of all food labels in a Brazilian supermarket. Foods were classified into eight groups according to Brazilian legislation and according to the presence or absence of the term whole grain. The prevalence of foods displaying the term whole grain or related expressions on the front label was assessed, and differences between groups were analyzed using Pearson's chi-squared test. Comparisons were also made in relation to the position of whole-grain ingredients in the ingredients list, given that Brazilian food labeling regulations require that ingredients be listed in descending order of weight on packaged foods. The level of significance was defined as p < 0.05. The sample included 1,004 processed and ultra-processed foods based on cereals and pseudocereals, 156 (15.6%) of which displayed the term whole grain and/or similar expressions on the front label. Of these, 98 (9.8%) contained the term whole grain, 25 (2.5%) displayed analogous expressions, and 33 (3.3%) contained the term whole grain concomitantly with analogous terms, identified in foods of the groups Bakery goods, bread, cereals, and related products and Sugars, sugary foods, and snacks. Half of the food products displaying the term whole grain or related expressions on the front label did not have a whole-grain ingredient listed in the first position of the ingredients list. The frequency of whole grains was even lower when analyzing the second and third ingredients. These findings reveal the existence of inaccurate information regarding the term whole grain or analogous expressions on the front label of cereal- and pseudocereal-based packaged foods. It is expected that these results will contribute to stimulating the food industry and regulatory bodies to improve the use of the term whole grain and related expressions on packaged food labels, given that, up to the moment of data collection, there were no regulatory requirements for these statements. Furthermore, the findings might contribute to improving the clarity of information available on food labels, thereby preventing consumer deception at the time of purchase.

Consumers' Response to Sugar Label Formats in Packaged Foods: A Multi-Methods Study in Brazil.

Providing information about the sugar content of packaged foods on product labels is an important strategy to lower consumers' sugar intake. This study assessed the effect of exposure to different sugar labels on consumers' understanding of the sugar content of foods and their food choices. In the first phase, five focus groups were conducted with a convenience sample of Brazilian adults to explore their perceptions about food labelling in general and sugar labelling in particular. Based on the qualitative results, four sugar label formats were developed and subsequently tested in a five-arm study on 1,277 adults via a randomised controlled online survey. The formats were: (i) no sugar information-control, (ii) total and added sugar content displayed in the Nutrition Information Panel (NIP), (iii) a front-of-package (FoP) octagonal warning for "high-in-sugar" products, (iv) a FoP magnifying glass warning for "high-in-sugar" products, and (v) a "high-in-sugar" warning text embedded on the NIP. Participants from the focus groups reported being confused about the meaning of "sugar" and "added sugar" on food labels and indicated that more interpretive labels, such as the FoP warnings, would help them choose products with low sugar content. In the experiment, all intervention sugar label formats improved participants' understanding of the sugar content of the tested food products, with the FoP warnings (iii and iv) showing the best results. While non-significant differences among label conditions were observed for food choices, the FoP octagonal warning prompted participants to choose high-in-sugar products less often. Given current public policy agendas aiming to reduce added sugar intake, there is a need to strengthen food labelling policies and nutrition disclosure policies that target the display of added sugar and build consumer awareness in using these tools to avoid high-in-sugar products.

University Students' Knowledge and Perceptions About Concepts, Recommendations, and Health Effects of Added Sugars.

It is recommended to limit added sugars to below 10% of the daily energy intake, as excessive consumption has been associated with several chronic non-communicable diseases. This exploratory qualitative study used focus groups to investigate the knowledge and perception of Brazilian university students about added sugars concepts, consumption recommendations, and health effects. Focus groups were led by a moderator using a semi-structured discussion guide. The focus groups were recorded, transcribed verbatim, and subjected to thematic analysis. Five focus groups were conducted with a total of 32 participants (50% women, mean age 23 years). Participants could not distinguish added sugars from sugars naturally present in foods and were unaware of the health impacts associated with excessive added sugar consumption, except for the risk of diabetes. Although most participants reported limiting sugar consumption, they had no knowledge of official consumption recommendations. Given that current public policy agendas aim to reduce added sugar intake, there is a need to strengthen strategies for disseminating information on added sugar concepts, recommendations, health effects and how to identify them in the foods products.

Trans-Fat Labeling in Packaged Foods Sold in Brazil Before and After Changes in Regulatory Criteria for Trans-Fat-Free Claims on Food Labels.

Consumption of industrially produced trans-fat acids (TFA) is a public health concern. Therefore, it is important that information on TFA in packaged foods be clearly informed to consumers. This study aimed to assess the evolution of TFA information presented in packaged foods sold in Brazil in 2010 and 2013, before and after the introduction of stricter regulatory requirements for TFA-free claims on food labels. A repeated cross-sectional study was performed through food label censuses of all packaged foods available for sale in two stores from the same supermarket chain, totaling 2,327 foods products in 2010 and 3,176 in 2013. TFA-free claims and information indicating TFA in the ingredients list and nutrition facts label were analyzed by descriptive statistics and Pearson's chi-square test. There was a 14% decrease in the use of ingredients containing or potentially containing industrially produced TFA (i-TFA), according to analysis of the ingredients list. However, when analyzing foods by groups, it was found that this decrease was significant only for group A (bakery goods, bread, cereals, and related products; from 59 to 35%, p < 0.001). By contrast, food group F (gravies, sauces, ready-made seasonings, broths, soups, and ready-to-eat dishes) showed a 5% increase in i-TFA. The use of specific terms for i-TFA decreased between 2010 and 2013, but there was an increase in the use of alternative terms, such as vegetable fat and margarine, which do not allow consumers to reliably identify whether a food product is a possible source of i-TFA. There was an 18% decrease in the use of TFA-free claims in products containing or potentially containing i-TFA. However, almost one-third of foods sold in 2013 were false negatives, that is, foods reported to contain 0 g of TFA in the nutrition facts label or with TFA-free claims but displaying specific or alternative terms for i-TFA in the ingredients list. The results indicate that adoption of stricter requirements for TFA-free claims on food labels in Brazil helped reduce the prevalence of such claims but was not sufficient to decrease i-TFA in industrialized foods sold in supermarkets.

Food additives in childhood: a review on consumption and health consequences.

OBJECTIVE: To discuss the context of scientific publications on the consumption of food additives by children and the possible health consequences in this age group. METHODS: A literature review, with a search carried out between April 2020 and April 2021 in the Web of Science, Scopus, PubMed and Google Scholar databases, as well as in websites of Brazilian and foreign official bodies. Official documents and studies published since 2000 were selected. Keywords related to food additives, children, food consumption, and health were used for the search. RESULTS: Food additives are substances intentionally added to foods for technological purposes. Processed foods are the main sources of additives in food and their consumption occurs since childhood. It is observed, however, that there are limitations inherent to the scientific method regarding the analysis of consumption and toxicity of food additives in humans, causing scarcity of data in the scientific literature. Additionally, existing data suggest that the additives have a higher toxic potential in children, considering that the body weight in this age group is lower than in adults. This context emphasizes the need to observe the precautionary principle, according to which risks of harm must be prevented. CONCLUSIONS: This is a scenario in which the literature points to a risk to people's health and, in particular, to children, about whom the duty of protection must be even greater, with absolute priority. Thus, the relevance of an expanded technical-scientific debate regarding the establishment of specific and stricter parameters for children is considered, regarding the consumption and toxicity of additives, as well as the different sources of exposure to these substances.

RESUMO OBJETIVO Discutir o contexto das publicações científicas sobre consumo de aditivos alimentares por crianças e as possíveis consequências à saúde nessa faixa etária. MÉTODOS Revisão de literatura, com busca realizada entre abril de 2020 e abril de 2021 nas bases de dados Web of Science, Scopus, PubMed e Google Acadêmico, bem como em sites de órgãos oficiais brasileiros e estrangeiros. Foram selecionados documentos oficiais e estudos publicados a partir do ano 2000. Para a busca, foram utilizados unitermos relacionados a aditivos alimentares, crianças, consumo alimentar e saúde. RESULTADOS Aditivos alimentares são substâncias adicionadas intencionalmente aos alimentos para fins tecnológicos. Os alimentos industrializados são as principais fontes de aditivos na alimentação e seu consumo ocorre desde a infância. Observa-se, contudo, que há limitações inerentes ao método científico no que tange à análise de consumo e de toxicidade de aditivos alimentares em humanos, ocasionando escassez de dados na literatura científica. Adicionalmente, dados existentes sugerem que os aditivos apresentam potencial tóxico maior em crianças, considerando que o peso corporal nessa faixa etária é menor em relação ao adulto. Esse contexto ressalta a necessidade de se observar o princípio da precaução, segundo o qual devem-se prevenir os riscos de dano. CONCLUSÕES Trata-se de cenário no qual a literatura aponta risco à saúde das pessoas e, em especial, das crianças, cujo dever de proteção deve ser ainda maior, com absoluta prioridade. Assim, pondera-se a relevância de um debate técnico-científico ampliado quanto ao estabelecimento de parâmetros específicos e mais rígidos para crianças, considerando consumo e toxicidade de aditivos, bem como as diversas fontes de exposição a essas substâncias.

Association of personal characteristics and cooking skills with vegetable consumption frequency among university students.

Most university students are transitioning to adulthood, and tend to adopt unhealthy eating habits characterised by a low intake of fruits and vegetables. Few studies have specifically addressed the consumption of vegetables, which have a high content of minerals, fibre, and active compounds. The aim of this investigation was to assess vegetable consumption frequency among university students in a Brazilian capital and examine associations with individual characteristics and cooking skills. This crosssectional study used a online questionnaire to collect data. Cooking skills were evaluated in eight dimensions. Vegetable consumption was recorded in five frequency groups and then categorised into daily and non-daily consumption. Data were subjected to Pearson's chi-squared or analysis of variance followed by Bonferroni post hoc test. Associations between cooking skill dimensions and daily vegetable consumption were identified by crude and adjusted logistic regression analyses.Adjustment was performed for sex, age, paternal education, and overweight/obesity.Results are expressed as odds ratios (p < 0.05). Less than half of the respondents (N = 237; 45%) reported consuming vegetables daily. Higher level of paternal education, not being overweight or obese, and higher scores on seven cooking skill dimensions were positively associated with daily vegetable consumption. Given the scarcity of research on the topic, the findings of this study make a significant contribution to knowledge and may support public health strategies for promoting vegetable consumption among university students.

The adaptation, validation, and application of a methodology for estimating the added sugar content of packaged food products when total and added sugar labels are not mandatory.

Nutrition policies recommend limiting the intake of added sugars. Information about added sugar content is not provided on packaged foods in Brazil, and even total sugar content information is often absent. This study aimed to (i) adapt a systematic methodology for estimating added sugar content in packaged foods when information on total and added sugar contents is not mandatory on labels, (ii) apply the adapted methodology to a Brazilian food composition database to estimate the extent of added sugar content in the national food supply, and (iii) assess the validity of the adapted methodology. We developed an 8-step protocol to estimate added sugar content using information provided on food labels. These steps included objective and subjective estimation procedures. Mean, median, and quartiles of the added sugar content of 4,805 Brazilian foods were determined and presented by food categories. Validity was assessed using a US database containing values of added sugar as displayed on the product labels. Objective estimation of added sugar content could be conducted for 3,119 products (64.9%), with the remainder 1,686 (35.1%) being assessed using subjective estimation. We found that 3,093 (64.4%) foods contained added sugar ingredients and the overall estimated median added sugar content was 4.7 g (interquartile range 0-29.3) per 100 g or 100 ml. The validity testing on US data for products with known added sugar values showed excellent agreement between estimated and reported added sugar values (ICC = 0.98). This new methodology is a useful approach for estimating the added sugar content of products in countries where both added and total sugar information are not mandated on food labels. The method can be used to monitor added sugar levels and support interventions aimed at limiting added sugar intake.

Cooking skills during the Covid-19 pandemic / Habilidades culinárias em tempos de pandemia pela Covid-19

ABSTRACT This article aims to present reflections on cooking skills in times of the coronavirus disease 2019 pandemic. The current period of uncertainty and isolation heightens food insecurity issues, influencing food choice, purchase, and preparation. Social media and networks are sources of entertainment and learning, with vast resources for cooking skills, which can stimulate home cooking and strengthen family ties. Research has evidenced the positive relationship between cooking and diet quality, an important factor for groups at increased risk of severe illness from Covid-19. For some individuals, cooking may be a strategy to reduce anxiety and stress associated with the pandemic. However, the Brazilian reality is marked by inequalities in income and access to food. Thus, more vulnerable populations may not have the same relationship with cooking. Public policies should focus on food and nutrition programs and actions for the development of cooking skills as a means to promote healthy eating and encourage self-care.

RESUMO Este artigo tem por objetivo apresentar considerações acerca de habilidades culinárias em tempos de pandemia pela Covid-19. O cenário vivenciado durante a pandemia, caracterizado pela incerteza e pelo isolamento, perpassa a questão de insegurança da alimentação, influenciando escolha, aquisição e preparo de alimentos, dentro e fora de casa. Mídias e redes sociais aparecem como alternativas de entretenimento e de aprendizado de habilidades culinárias, estimulando o preparo de refeições em casa e reforçando as relações familiares na cozinha. Evidências mostram relação da prática das habilidades culinárias com a qualidade da alimentação, que é condição significativa principalmente no cuidado com os indivíduos classificados como grupo de risco para Covid-19. Cozinhar, para alguns indivíduos, pode ainda ser uma estratégia para reduzir sentimentos como estresse e ansiedade, comuns no contexto da pandemia. A realidade brasileira, no entanto, é marcada por desigualdades tanto de acesso como de renda, de forma que populações mais vulneráveis podem não ter essa mesma relação com o ato de cozinhar. Nesse sentido, sugere-se investir em políticas públicas de alimentação e de nutrição que executem programas e ações para desenvolvimento de habilidades culinárias, visando à promoção da alimentação saudável e ao estímulo ao autocuidado.

Positive impact of a cooking skills intervention among Brazilian university students: Six months follow-up of a randomized controlled trial.

OBJECTIVES: The purpose of this study was to determine the effects of the Nutrition and Culinary in the Kitchen (NCK) Program to evaluate the improvement of cooking skills and healthy eating of university students. METHODS: A randomized controlled trial with six months follow-up was used incorporating an intervention group (IG) and a control group (CG). The IG participated in the NCK program over a six-week period, three hours weekly, based on five hands-on cooking classes and one food market visit, while CG continued their usual activities. Outcome measures included changes in relation to a) accessibility and availability of fruits and vegetables (AAFV); b) cooking attitudes (CA); c) cooking behaviors at home (CBH); d) cooking behaviors away from home (CBAH) e) produce consumption self-efficacy (SEPC); f) self-efficacy for using cooking techniques (SECT); g) self-efficacy for using fruits, vegetables, and seasonings (while cooking) (SEFVS); and h) knowledge of cooking terms and techniques (CTT). An online self-completed validated survey was answered, at three time points: baseline (T1), after intervention (T2) and six months after intervention (T3). Statistical analyses were conducted to evaluate changes in outcomes within and between groups over time. RESULTS: 76 students completed the online questionnaire at the 3 time points. Findings revealed a statistically significant increase (p < 0.05) in all outcomes evaluated in the IG, except for CBH and CBAH. This effect was sustained at T3 (p < 0.001). Results were similar to the adjusted model (p < 0.001), thus, indicating that IG changes, when compared to CG, were due to the intervention effect. CONCLUSION: NCK culinary intervention program demonstrated efficacy for the increased on AAFV, CA, SEPC, SECT, SEFVS and CTT with university students.

Development of culinary recipes in an intervention program with Brazilian university students / Desenvolvimento de receitas culinárias em programa de intervenção com universitários brasileiros

ABSTRACT Objective Develop and test recipes for a cooking skills intervention program aimed at students of a Brazilian university. Methods Culinary recipes were selected for the Nutrition and Culinary in the Kitchen program, which offers cooking classes for participants to practice and develop their cooking skills. The Nutrition and Culinary in the Kitchen program is based on the Cooking with a Chef program of the United States of America. A literature search was conducted to establish criteria for the selection and development of recipes. A decision tree was constructed to determine if Cooking With a Chef recipes were appropriate for the Nutrition and Culinary in the Kitchen program. Recipes were evaluated in the laboratory by untrained university students using an acceptance test that comprised the analysis of sensorial attributes and healthiness criteria. Results Of the 32 developed recipes, nine were based on the Cooking With a Chef program. Recipes were adapted to increase the use of fresh fruits, whole grains, and vegetables; eliminate ultra-processed foods; and take into account local food habits and seasonality of ingredients. In the first test, 53.3% (n=16) of the dishes received an acceptance score of less than 70.0% mainly because of unsatisfactory taste. Culinary recipes considered inadequate were redesigned in terms of ingredients and/or cooking methods and were retested until achieving a score of 100.0%. Conclusion Culinary recipes adapted to the Brazilian food culture and the target audience with the use of healthy ingredients and cooking techniques were considered appropriate for the Nutrition and Culinary in the Kitchen cooking skills intervention program and might increase participants' adherence to healthy eating habits.

No primeiro teste, 53,3% (n=16) das preparações culinárias obtiveram percentual de adequação abaixo de 70,0%, principalmente devido ao sabor. As preparações consideradas inadequadas tiveram alterações nos ingredientes ou no modo de preparo, sendo testadas até atingirem 100,0% de adequação. Conclusão As receitas culinárias adaptadas de acordo com a cultura brasileira e o público-alvo, inserindo-se ingredientes e técnicas de preparo mais saudáveis, foram consideradas adequadas ao programa proposto e podem contribuir para a adesão ao programa de intervenções que visa o desenvolvimento de hábitos alimentares mais saudáveis.

The concept of cooking skills: A review with contributions to the scientific debate / O conceito de habilidades culinárias. uma revisão com contribuições ao debate científico

ABSTRACT This paper aimed to conduct a literature review about the concept of cooking skills to contribute to the scientific debate about the subject. A systematic search was performed in the Scopus, PubMed/MedLine and Web of Science databases as well as the periodicals of the Federal Agency for Support and Evaluation of Graduate Education in Brazil Coordenação de Aperfeiçoamento de Pessoal de Nível Superior website, using the following Portuguese and English keywords: cooking skills, cooking and food/meal preparation. We also consulted references cited by these papers, electronic dictionaries (in Portuguese, English and French), technical documents found on public and private institutional websites, as well as books. Basic, etymological/vernacular and systematic definitions for cooking were identified, including historical global and national contexts. To conceptualize cooking skills, categories related to food and individuals were established, purposing a conceptual model. The category related to food referred to the use of unprocessed/minimal processed foods (which require procedures prior to their preparation), and/or processed/ultra-processed foods (which need a little or no preparation, such as re-heating). The category related to individuals involved dimensions such as confidence, attitudes, behavior, and individual knowledge used to prepare foods. The historical definitions of cooking allowed us to clarify the concept of cooking skills. Considering the global context of valuing and recovering cooking for the promotion of healthy eating, this review can contribute to the scientific discussion about the concept of cooking skills. The purposed conceptual model enables parameters to be established for further investigations, allowing cooking interventions to be directed toward promoting healthy eating.

RESUMO O objetivo do artigo foi realizar uma revisão de literatura sobre o conceito de habilidades culinárias, a fim de contribuir para o debate científico sobre o tema. Foi realizada busca sistemática de artigos nas bases de dados Scopus, PubMed/MedLine, Web of Science e portal de periódicos da Coordenação de Aperfeiçoamento de Pessoal do Ensino Superior, utilizando os seguintes descritores em português e inglês: habilidades culinárias, culinária, preparo dos alimentos/das refeições. Consultaram-se ainda referências citadas por esses artigos, dicionários eletrônicos (nos idiomas português, inglês e francês), documentos técnicos capturados em sites institucionais públicos ou privados, bem como livros. Identificaram-se definições para culinária denominadas como básicas, etimológicas/vernáculas e sistemáticas, incluindo um resgate histórico da culinária no contexto mundial e no Brasil. Para conceituar habilidades culinárias, foram estabelecidas categorias relacionadas aos alimentos e aos indivíduos, propondo-se um modelo conceitual. A categoria relacionada aos alimentos refere-se ao uso de alimentos in natura/minimamente processados (que requerem procedimentos prévios ao seu preparo), e/ou processados/ultraprocessados (que requerem pouco ou nenhum preparo, como reaquecimento). A categoria relacionada aos indivíduos envolveu dimensões como confiança, atitude, comportamento e conhecimentos individuais empregados para preparar os alimentos. As definições históricas de culinária permitiram elucidar o conceito de habilidades culinárias. Considerando o contexto mundial de valorização e resgate da culinária na promoção da alimentação saudável, essa revisão pode contribuir para o debate científico em torno do conceito de habilidades culinárias. O modelo conceitual proposto possibilita estabelecer parâmetros para avaliação em futuras investigações, permitindo direcionar intervenções culinárias para promoção da alimentação saudável.

Nutrition and Culinary in the Kitchen Program: a randomized controlled intervention to promote cooking skills and healthy eating in university students - study protocol.

BACKGROUND: Community-based intervention studies that aim at developing cooking skills have increased in the scientific literature and are related to healthier food practices. However, methodological limitations are observed and only a few studies have university students as the target. The university entrance period has been related to negative changes in eating habits among young people and it represents an important period for developing interventions for health promotion. This study describes the study protocol and the evaluation framework for the Nutrition and Culinary in the Kitchen program. This program aims to develop cooking skills in university students, and is based on the Cooking with a Chef program in the United States. METHODS: This ongoing, randomized controlled intervention was designed with a six month follow-up study. The intervention consisted of three-hour weekly classes during a six week period with printed materials provided. Five of the classes were hands-on cooking and one was a tour to a popular food market. There were eight primary outcome measures: changes in relation to i) accessibility and availability of fruits and vegetables; ii) cooking attitudes; iii) cooking behaviors at home; iv) cooking behaviors away from home; v) produce consumption self-efficacy; vi) self-efficacy for using basic cooking techniques; vii) self-efficacy for using fruits, vegetables, and seasonings (while cooking); and viii) knowledge of cooking terms and techniques. Secondary outcomes included changes in body mass index and in personal characteristics related to cooking. Repeated measures were collected through the application of an online self-completed survey, at baseline, after intervention and six months after intervention. A sample of 80 university students (40: intervention group; 40: control group) was estimated to detect a mean change of 1.5 points in cooking knowledge, with study power of 80%, and 95% level of confidence, plus 20% for random losses and 10% for confounding factors. The control group participants have continued with their usual activities. Data analyses will evaluate the intervention effect on changes in outcomes within and between groups, as well as explore relations with personal characteristics. DISCUSSION: This method provides new evidence about whether or not a culinary intervention targeting university students has an impact on the improvement of cooking skills and healthy eating practices.

Food intake of university students / Consumo alimentar de estudantes universitários

ABSTRACT This narrative literature review aimed to analyze the results of studies on the food intake of university students. A literature search was conducted in July 2014 and updated in July 2016 in the Scopus, MedLine/PubMed, and SciELO databases, using descriptors related to university students and food intake in English and Portuguese. Overall, 37 studies that analyzed university students' food intake were included in this review, eight of which were conducted in Brazil. The results demonstrated that most university students have unhealthy eating behaviors, such as high intake of fast foods, snacks, sweets, soft drinks, and alcoholic beverages, and low intake of fruits, vegetables, fish, whole grains, and legumes. Undergraduate students of health sciences, such as nursing, nutrition, and medicine, did not have healthier diets. University students' food intake was characterized as unhealthy, regardless of undergraduate program or sex, especially among students who left the parents' home and became responsible for their own food. Therefore, there is a need of developing public policies that promote healthy eating habits among students, such as interventions to change their eating habits and increase their access to healthy foods at the university environment.

RESUMO O estudo teve o objetivo de realizar revisão narrativa de literatura para analisar os resultados de estudos sobre o consumo alimentar de estudantes universitários. Realizou-se busca bibliográfica, em julho de 2014, atualizada em julho de 2016, nas bases de dados Scopus, MedLine/PubMed e SciELO, utilizando unitermos relacionados a estudantes universitários e a consumo alimentar, em língua inglesa e portuguesa. No total, 37 artigos sobre o consumo alimentar de universitários foram analisados e discutidos nesta revisão. Dentre os estudos incluídos, 8 foram realizados no Brasil. Os resultados dos estudos demonstram que a maioria dos estudantes universitários apresenta comportamentos alimentares pouco saudáveis, como o elevado consumo de fast food, snacks, doces, refrigerantes e bebidas alcoólicas, bem como baixo consumo de frutas, legumes, verduras, peixes, cereais integrais e leguminosas. Cursar graduação na área da saúde, como enfermagem, nutrição e medicina não foi indicativo de ter uma alimentação mais saudável. O consumo alimentar de estudantes universitários foi caracterizado como pouco saudável, independentemente de curso de graduação e sexo, destacando-se aqueles estudantes que saíram da casa dos pais e passaram a ser responsáveis pela própria alimentação. Sugere-se a elaboração de políticas públicas que estimulem a promoção da alimentação saudável dos estudantes, a exemplo de intervenções para mudanças nas práticas alimentares e para aumento do acesso a alimentos saudáveis no ambiente universitário.

Benefits and risks of fish consumption for the human health / Benefícios e riscos do consumo de peixes para a saúde humana

The article aimed at identifying and discussing scientific evidences on the benefits and risks of fish consumption the human health. There was a systematic survey for articles published from 2003 and May 2011, at the MedLine, Scopus, SciELO, Lilacs and Google Scholar databases. The key words used were: fish, food intake, omega-3 fatty acids, fatty fish, benefits, risk, and consumption. The search produced 12,632 articles, 25 eligible cohort studies on possible benefits, 61 on risks and 10 studies that assessed the "risk/benefit" relation. Of the 25 works, 14 suggested a preventive effect of fish consumption related to cardiovascular diseases, depression, cataract and some types of cancer. Evidences of a relation between exposure to mercury and an increase in the risk of neurological disorders, but not of cardiovascular diseases, were also found. Given the importance of fish consumption, its possible risks and the lack of Brazilian studies on the topic, it is important to conduct more longitudinal studies that assess both the benefits and risks of fish consumption for the human health. We also emphasize the need for policies to reduce exposure of fish and seafood to mercury and other contaminants.

O artigo objetivou identificar e discutir evidências científicas sobre benefícios e riscos do consumo de peixes para a saúde humana. Realizou-se uma busca de artigos publicados entre 2003 e maio de 2011, nas bases de dados MedLine, Scopus, SciELO, Lilacs e Google acadêmico. Utilizaram-se as palavras chaves: fish, food intake, omega-3 fatty acids, fatty fish, benefits, risk, consumption. Encontraram-se 12.632 artigos, sendo elegíveis 25 estudos de coorte que investigaram possíveis benefícios, 61 sobre riscos e 10 estudos que avaliam a relação "risco/benefício". Dentre os 25 trabalhos, 14 sugeriram efeito protetor do consumo de peixes, relacionado a doenças cardiovasculares, depressão, catarata e alguns tipos de câncer. Foram encontradas evidências de relação entre exposição ao mercúrio e aumento do risco de distúrbios neurológicos, mas não do risco de doenças cardiovasculares. Tendo em vista a importância do consumo de peixes e seus possíveis riscos, bem como a escassez de pesquisas nacionais sobre o tema, observa-se a relevância de se realizarem mais estudos longitudinais que aliem a avaliação dos benefícios e riscos do seu consumo para a saúde humana. Ressalta-se também a necessidade de políticas para redução da exposição de peixes e frutos do mar ao mercúrio e outros contaminantes.

Aquecimento de vinho tinto e suco de uva utilizados em preparações culinárias não afeta a capacidade antioxidante e o teor de fenóis totais / Heating of red wine and grape juice in food preparations does not affect their antioxidant capacity and total phenol content

OBJETIVO: Avaliar a capacidade antioxidante e a concentração dos compostos fenólicos de vinho tinto e suco de uva utilizados em preparações culinárias, quando submetidos ao processo de fervura. Métodos: A avaliação ocorreu após diferentes períodos de aquecimento (100ºC) em dois sistemas: i) panela de alumínio e chama de fogão e ii) balão de vidro e manta térmica. Amostras comerciais de vinho tinto (n=4) e suco de uva integral (n=4) foram submetidas à fervura por 10, 20 e 60 minutos. Antes e após cada período de fervura, a capacidade antioxidante total foi avaliada pela medida do potencial redutor férrico, e o teor de fenóis totais foi quantificado pelo método de Folin-Ciocalteau. As diferenças foram comparadas pela análise de variância para medidas repetidas (p<0,05). Resultados: A fervura durante os diferentes períodos de tempo não provocou variações importantes na capacidade antioxidante total e no teor de fenóis totais das bebidas, independentemente do sistema de aquecimento utilizado. Conclusão: De acordo com os resultados obtidos, as propriedades antioxidantes do vinho tinto e do suco de uva, quando submetidos à fervura por até 60 minutos, mantiveram-se relativamente estáveis.

Objective: This study evaluated the antioxidant capacity and concentration of phenolic compounds in red wine and grape juice used in culinary preparations subjected to boiling. Methods: The assessments were done after different boiling times (100ºC) using two systems: i) aluminum pot and stove flame and ii) volumetric flask and heating mantle. Samples of red wine (n=4) and grape juice (n=4) were subjected to boiling for 10, 20 and 60 minutes. Before and after each boiling period, the total antioxidant capacity was evaluated by the ferric reducing antioxidant power assay and the total phenol content was determined by the Folin-Ciocalteu reagent. Differences were compared by repeated measures analysis of variance (RM-ANOVA) (p<0.05). Results: The different boiling times did not cause significant changes in the total antioxidant capacity or total phenol content of the beverages, regardless of boiling method. Conclusion: The results show that the antioxidant properties of red wine and grape juice did not change significantly after boiling for 60 minutes.
