Vegetable consumption is a predictor for improved health outcomes, such as reduced obesity and likelihood of food-related noncommunicable diseases. Young adults are a key population, being in a transitional stage-of-life: Habits gained here are taken through the lifespan. This review establishes insight into the consumption of vegetables among young adults during their college/university years, and factors associated with increased consumption. Seventy-one papers were extracted, published between January 2009 and October 2018. Search terms related to consumption; vegetables; and college/university setting and sample. A diverse range of definitions, guidelines, and study approaches were observed. Findings identify that the majority of students do not consume World Health Organization recommendations. Being female was the most frequent predictor of higher intake of vegetables, and no consumption patterns were identified by countries. Living at family home; body mass index; happiness and stress level; perceived importance of healthy eating; socioeconomic level; breakfast consumption; stage of study; openness to new experiences; sleep pattern; nutrition knowledge; activity level; alcohol usage; and energy intake were identified as influential factors. Public policies and new strategies to encourage vegetable consumption among college students are indispensable, especially targeting subgroups with even lower intakes, such as males and those living outside family home.

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.

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. 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. 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.

The presentation of nutrition information on a serving size basis is a strategy that has been adopted by several countries to promote healthy eating. Variation in serving size, however, can alter the nutritional values reported on food labels and compromise the food choices made by the population. This narrative review aimed to discuss (1) current nutrition labelling legislation regarding serving size and (2) the implications of declared serving size for nutrition information available on packaged foods. Most countries with mandatory food labelling require that serving size be presented on food labels, but variation in this information is generally allowed. Studies have reported a lack of standardisation among serving sizes of similar products which may compromise the usability of nutrition information. Moreover, studies indicate that food companies may be varying serving sizes as a marketing strategy to stimulate sales by reporting lower values of certain nutrients or lower energy values on nutrition information labels. There is a need to define the best format for presenting serving size on food labels in order to provide clear and easily comprehensible nutrition information to the consumer.

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.
