O presente artigo teve como objetivo revisar a literatura sobre hábitos alimentares de universitários brasileiros e identificar possíveis condicionantes.  A revisão consistiu na busca de artigos publicados entre 2004 e 2014 nas bases de dados Pubmed, Lilacs e Scielo, por meio da combinação dos termos: college students, university, nutrition, diet, food consumption, eating habits, food intake, dietary intake.  Outra estratégia foi a busca manual nas listas de referências dos artigos identificados e selecionados por meio da pesquisa eletrônica. Optou-se por excluir publicações com amostra indivíduos exclusivamente do sexo feminino, selecionando-se 9 artigos para análise. Os principais fatores associados ao consumo alimentar entre universitários brasileiros foram rendimento familiar, dupla jornada de estudo e trabalho, área do curso de graduação, estado nutricional, sexo e local de realização das refeições.  A produção científica sobre consumo alimentar de universitários brasileiros é escassa, destacando-se maiores contribuições nos últimos 5 anos. Em relação aos métodos utilizados, predominam questionários de frequência alimentar. A análise sob a ótica de padrões de consumo alimentar, a necessidade de relacionar o consumo com medidas de desfecho e a necessidade de estudos longitudinais com essa população se fazem necessários, levando em consideração delineamentos adequados, do ponto de vista dos condicionantes do consumo alimentar do ponto de vista sociodemográfico, ambiental e individual.

Urine Biomarker

Improvement of diet at the population level is a cornerstone of national and international strategies for reducing chronic disease burden. A critical challenge in generating robust data on habitual dietary intake is accurate exposure assessment. Self-reporting instruments (e.g., food frequency questionnaires, dietary recall) are subject to reporting bias and serving size perceptions, while weighed dietary assessments are unfeasible in large-scale studies. However, secondary metabolites derived from individual foods/food groups and present in urine provide an opportunity to develop potential biomarkers of food intake (BFIs). Habitual dietary intake assessment in population surveys using biomarkers presents several challenges, including the need to develop affordable biofluid collection methods, acceptable to participants that allow collection of informative samples. Monitoring diet comprehensively using biomarkers requires analytical methods to quantify the structurally diverse mixture of target biomarkers, at a range of concentrations within urine. The present article provides a perspective on the challenges associated with the development of urine biomarker technology for monitoring diet exposure in free-living individuals with a view to its future deployment in “real world” situations. An observational study (n = 95), as part of a national survey on eating habits, provided an opportunity to explore biomarker measurement in a free-living population. In a second food intervention study (n = 15), individuals consumed a wide range of foods as a series of menus designed specifically to achieve exposure reflecting a diversity of foods commonly consumed in the UK, emulating normal eating patterns. First Morning Void urines were shown to be suitable samples for biomarker measurement. Triple quadrupole mass spectrometry, coupled with liquid chromatography, was used to assess simultaneously the behavior of a panel of 54 potential BFIs. This panel of chemically diverse biomarkers, reporting intake of a wide range of commonly-consumed foods, can be extended successfully as new biomarker leads are discovered. Towards validation, we demonstrate excellent discrimination of eating patterns and quantitative relationships between biomarker concentrations in urine and the intake of several foods. In conclusion, we believe that the integration of information from BFI technology and dietary self-reporting tools will expedite research on the complex interactions between dietary choices and health.

Background Given the recognized importance of preventing poor dietary behaviors during adolescence, we need a better understanding of college students’ dietary behaviors. Studies have found that individual factors and electronic health (eHealth) literacy may affect one’s dietary behaviors. However, few studies have fully investigated the effect of the three levels of eHealth literacy (functional, interactive, and critical) and the interactive effect of individual factors (eg, gender, monthly expenses, and frequency of cooking) and the three levels of eHealth literacy on the four aspects of dietary behaviors (consumer health, balanced diet, regular eating habits, and unhealthy food intake). Objective This study aimed to investigate whether individual differences and higher eHealth literacy are associated with more positive dietary behaviors and less unhealthy dietary intake. Methods The eHealth Literacy Scale is a 12-item instrument designed to measure college students’ functional, interactive, and critical eHealth literacy. The Dietary Behaviors Scale is a 14-item instrument developed to measure four aspects of dietary behaviors of college students. A questionnaire was administered to collect background information about participants’ gender, monthly expenses, and frequency of cooking. A national sample of college students was surveyed, and 813 responses were obtained. We conducted a multiple regression analysis to examine the association among individual factors, eHealth literacy, and dietary behaviors. Results This study found that functional eHealth literacy was negatively related to unhealthy food intake (beta=−.11; P=.01), and interactive eHealth literacy was positively related to balanced diet (beta=.25; P<.001) and consumer health (beta=.15; P=.02). Moreover, critical eHealth literacy was positively related to consumer health (beta=.30; P<.001) and regular eating habits (beta=.20; P=.002). Finally, the interactive effect between gender and interactive eHealth literacy was negatively related to balanced diet (beta=−.22; P<.001). The interactive effect between monthly expenses and functional eHealth literacy was positively related to balanced diet (beta=.07; P=.03), although the interactive effect between monthly expenses and critical eHealth literacy was negatively related to balanced diet (beta=−.10; P=.047). Conclusions This study showed that Taiwanese college students with higher functional eHealth literacy were more likely to engage in fewer unhealthy food consumption practices. Those who had higher interactive and critical eHealth literacy were more likely to engage in positive dietary behaviors than those with functional eHealth literacy. Surprisingly, females with high interactive eHealth literacy were more likely to have a poor balanced diet. In contrast, students with higher monthly expenses and higher functional eHealth literacy were more likely to have a balanced diet. However, students with higher monthly expenses and higher critical eHealth literacy were less likely to maintain a balanced diet.

Abstract Ultra-processed food is one of the main contributors to energy supply and consumption in food systems worldwide, and evidence of their detrimental health outcomes in humans is emerging. This study aimed to assess ultra-processed food intake and its association with urinary levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG), a biomarker of DNA oxidative damage, in 139 healthy adolescents in Karaj City in Iran. Usual dietary intake was measured using a 168-item validated FFQ. The daily intake of ultra-processed food consumption was determined through the classification of NOVA, and general linear models were used to compare the urinary levels of 8-OHdG/creatinine (ng/mg creatinine) within tertiles of ultra-processed food intake. Adolescents in the higher tertile of ultra-processed food consumption had a significantly higher mean level of urinary 8-OHdG/creatinine in comparison with the lower tertiles in the crude model (Pfor trend: 0·003) and after adjustment for confounding variables, including total energy intake, sex, age, BMI for age Z-score, obesity and physical activity (Pfor trend: 0·004). This association was still significant after adjusting for dietary intake of whole grains, nuts, legumes, the ratio of MUFA:SFA (g/d) and Mediterranean dietary score (Pfor trend: 0·002). More studies are needed to explore the determinants of ultra-processed food supply, demand, consumption and health effects; such studies should be applied to develop evidence-informed policies and regulatory mechanisms to improve children’s and adolescents’ food environment policymaking and legislation with special attention to ultra-processed food.

Unhealthy Food

Both regulatory agencies and nonprofit organizations seek to understand how different tactics and appeals contained in food and public health advertisements might influence the food intake of an increasingly dieting-concerned population. This article addresses this important issue by examining how consumers who are concerned with their diets react to rich images of unhealthy food consumption. Results of two experiments show that exposure to food advertisements containing unhealthy food consumption imagery reduces food intake among consumers chronically concerned with dieting, whereas a third experiment shows a similar decrease in intended consumption when a public health advertisement portrays the consumption of unhealthy food. These findings in turn offer guidelines for maximizing the effectiveness of messages that attempt to promote healthy eating habits. Additionally, this research provides theoretical contributions to the self-control and mental imagery research domains which have public policy implications for regulatory agencies and nonprofit organizations.

Food Consumption Data

Abstract Introduction Understanding the various eating habits of different population groups, according to the geographical area, is critical to develop evidence-based policies for nutrition and food safety. The FAO/WHO Global Individual Food consumption data Tool (FAO/WHO GIFT) is a novel open-access online platform, hosted by FAO and supported by WHO, providing access to harmonized individual quantitative food consumption (IQFC) data, especially in low- and middle-income countries (LMICs). Methods FAO/WHO GIFT disseminates IQFC data as ready-to-use food-based indicators in the form of infographics, and as microdata. The infographics intend to facilitate the use of these data by policy makers, providing an overview of key data according to population segments and food groups. The microdata is publicly available for download, and is intended for users that would like to do further analysis of the data. Results FAO/WHO GIFT is a growing repository. By June 2020, 14 datasets were available for dissemination and download, and an additional 44 datasets will be made available by 2022. FAO/WHO GIFT also provides an inventory of existing IQFC data worldwide, which currently contains detailed information on 268 surveys conducted in 105 countries. Conclusions FAO/WHO GIFT collates, harmonizes and disseminates IQFC data collected in different countries. This harmonization is aimed at enhancing the consistency and reliability of nutrient intake and dietary exposure assessments globally. FAO/WHO GIFT is developed in synergy with other global initiatives aimed at increasing the quality, availability and use of IQFC data in LMICs to enable evidence-based policy-making for better nutrition and food safety.

Improving dietary habits at a young age could prevent adverse health outcomes. The aim was to gain insight into the adequacy of the dietary intake of Dutch toddlers, which may provide valuable information for preventive measures. Data obtained from the Dutch National Food Consumption Survey 2012–2016 were used, which included 672 children aged one to three years. Habitual intakes of nutrients were evaluated according to recommendations set by the Dutch Health Council. Specific food groups were evaluated according to the Dutch food-based dietary guidelines. For most nutrients, intakes were estimated to be adequate. High intakes were found for saturated fatty acids, retinol, iodine, copper, zinc, and sodium. No statement could be provided on the adequacy of intakes of alpha-linoleic acids, N-3 fish fatty acids, fiber, and iron. 74% of the toddlers used dietary supplements, and 59% used vitamin D supplements specifically. Total median intakes of vegetables, bread, and milk products were sufficient. Consumption of bread, potatoes and cereals, milk products, fats, and drinks consisted largely of unhealthy products. Consumption of unfavorable products may have been the cause of the observed high and low intakes of several nutrients. Shifting towards a healthier diet that is more in line with the guidelines may positively affect the dietary intake of Dutch toddlers and prevent negative health impacts, also later in life.
