Resumo Objetivou-se identificar diferenças no consumo alimentar, segundo marcadores de alimentação saudável e não saudável, entre adultos residentes nas áreas urbanas e rurais do Brasil. Realizou-se estudo transversal com dados da Pesquisa Nacional de Saúde (2013). A alimentação foi avaliada por marcadores de alimentação saudável e não saudável. Estimou-se as prevalências (%) e modelos de regressão logística sequencial foram ajustados para estimar odds ratio (OR) e intervalos de confiança (IC95%). Verificou-se maior consumo de frutas e hortaliças, peixes, refrigerantes e substituições de refeições nas áreas urbanas, enquanto que, o consumo de carne com gorduras e feijão foi maior nas áreas rurais. Análises ajustadas mostraram maior consumo regular de feijão e de carne com excesso de gordura; e menor consumo de refrigerantes, de frutas e hortaliças e de substituição de refeições por lanches nas áreas rurais em comparação com as urbanas. Tendências semelhantes foram observadas nas macrorregiões do país. As diferenças no consumo alimentar de brasileiros residentes em áreas rurais e urbanas denotam a importância de fomentar políticas de alimentação que respeitem e valorizem as tradições e a cultura alimentar.

We aimed to evaluate the intake of dietary total polyphenols and their classes according to NOVA classification among adults of a Brazilian cohort study. This is a cross-sectional study, in which food consumption was assessed using an Food Frequency Questionnaire (FFQ) and polyphenol content (total and their classes) was estimated at Phenol-Explorer for each food category and presented as mean and 95% confidence interval. Adjusted linear regression was used to describe the trend of the association between the quintiles of polyphenols intake (dependent variable) and NOVA group of food consumption (independent variable). The higher consumption of fresh/minimally processed foods is accompanied by a higher intake of total polyphenols and all their classes, while the higher consumption of ultra-processed foods represented the lower intake of total polyphenols and their classes. Fresh foods are the greatest sources of polyphenols, and their daily consumption should be encouraged, while ultra-processed foods are deficient in such bioactive compounds. GRAPHICAL ABTSRACT

OBJECTIVE: To analyze the quantity and diversity in the consumption fruits and vegetables, as well as its relationship with the consumer’s purchase characteristics and food environment. METHODS: Baseline study stemming from a controlled and randomized community trial investigating a sample representative of Primary Health Care services (Health Academy Program) of Belo Horizonte, state of Minas Gerais. The intake of fruits and vegetables was analyzed in servings/day, whereas diversity was assessed by the Food Frequency Questionnaire. Users were also questioned on the frequency, purchase location and availability of these foods at their households. To assess the consumer’s food environment, commercial establishments within a 1.6 km radius around the program unit sampled were audited. RESULTS: 3,414 adults and older adults (88.1% women) were investigated, as well as 336 commercial establishments, in 18 units of the Health Academy Program. The average consumption of fruits and vegetables was adequate [5.4 (SD = 2.1) servings/day] but monotonous, with average daily intake of two different types. In the establishments audited, a good diversity (77.7% and 85.0%) and variety (74.5% and 81.4%) of fruits and vegetables was observed, although with lower quality of vegetables (60.4%). After adjusting for sociodemographic variables, we identified that knowledge on food crops (p = 0.006), increased monthly availability of fruits at households (p < 0.001), and greater variety of fruits (p = 0.03) and quality of vegetables (p = 0.05) in commercial establishments could improve the quantitative intake of fruits and vegetables, whereas a greater variety of fruits (p = 0.008) would increase consumption diversity. CONCLUSIONS: The intake of fruits and vegetables was quantitatively adequate but monotonous, being influences by the consumer environment. Such results highlight the need for improving educational actions in health services and programs, in addition to acting on the consumer environment, aiming to promote and maintain the adequate and diversified consumption, as recommended by Brazilian guidelines for proper and healthy eating.

This study aimed to develop community educational activities in Brazilian primary health care settings. A randomized controlled community trial was conducted to encourage fruit and vegetable consumption (FV-RCT) in a representative sample of consumers aged 20 years or older in a Brazilian city. The fruit and vegetable consumption was classified according to the transtheoretical model's stages of change, reflecting different degrees of readiness for change. The educational activities were based on the transtheoretical model and a problematizing-dialogic pedagogy, planned by an interdisciplinary team, using information collected in a qualitative pilot study. The actions were conducted over seven months, and baseline data were collected from 1483 participants. The educational strategies included workshops interspersed with motivational messages conveyed via postcard, interactive environment-based activities, and informative material. In the workshops, different techniques were used - conversation circles, image theatre, self-portraits, cooking and art as experience. The applied intervention based on the chosen theories implied in a refinement of the intervention, but, nevertheless, proved to be feasible for large population groups and to the scenario of health services. Thus, this interdisciplinary FV-RCT study represents an effort to advance methodological issues and provide theoretical subsidies for actions.
