Extra virgin olive oil: A comprehensive review of efforts to ensure its authenticity, traceability, and safety.

The growing demand for extra virgin olive oil (EVOO), appreciated for its unique organoleptic properties and health benefits, has led to various fraudulent practices to maximize profits, including dilution with lower value edible oils. The adulterated oils would be of poor nutritional quality, more readily oxidized, and may contain unhealthy substances formed during processing. Nevertheless, the range of available techniques to detect fraud in EVOO production has been growing. Reliable markers of EVOO adulteration include fatty acids and minor components such as sterols, tocopherols, triterpene alcohols, phenolic compounds, phospholipids, volatile compounds, and pigments. Additionally, increasing consumer interest in high-quality EVOO has led to the development of robust scientific methods for its traceability. This review focuses on (i) the usefulness of certain compounds as markers of EVOO adulteration; (ii) the potential health risks of consuming adulterated EVOO; and (iii) reliable methods for the geographical traceability of olive oil. In conclusion, fraudulent production practices need to be detected to preserve the beneficial health effects of EVOO and to avoid the potential risks associated with ingesting substandard oil. In this work, as EVOO certification and regulatory framework limitations have already been extensively reviewed, we focus our attention on biomarkers that guarantee both the authenticity and traceability of oil, and consequently its health properties. When it is unavailable to obtain a high-resolution mass spectrometry full fingerprint, stigmastadienes and the sterolic profile are proposed as reliable markers.

Physical activity patterns in adults: prevalence and associated factors / Padrão de atividade física em adultos: prevalência e fatores associados

Abstract Background Insufficient practice of physical activity associated with some factors related to life habits increase the risk of non-transmissible chronic diseases and reduce quality of life. Objective Identify the pattern of physical activity and associated factors in adults aged ≥20 years. Method A cross-sectional, population survey conducted with 600 individuals. Data on demographic, socioeconomic and behavioral aspects, work, and physical activities were collected through home interviews. Descriptive, bivariate and Poisson regression analyses were performed. Results Prevalence of insufficient physical activity was 35.0% (95% CI: 31.2-38.9). Zero to four years of schooling [PR=2.35; 95% CI: 1.07-5.15], working in sitting position [PR=1.52; 95% CI: 1.02-2.48], and number of days at the computer [PR=4.60; 95% CI: 2.38-14.28] remained in the final model for females, whereas 0-4 years [PR=2.30; 95% CI: 1.21-4.06] or 5-8 years [PR=3.70; 95% CI: 0.79-4.00] of schooling, working in sitting position [PR=2.22 95% CI: 1.36-3.62], number of days at the computer [PR=2.04; 95% CI: 1.26-3.32], and number of days of TV viewing [PR=2.12; 95% CI: 1.03-4.36] remained in the final model for males. Conclusion High prevalence of insufficient practice of physical activity is associated with schooling, working in sitting position, and number of days at the computer and TV viewing.

Resumo Introdução A prática insuficiente de atividade física associada a alguns fatores relacionados aos hábitos de vida aumenta o risco de doenças crônicas não transmissíveis e reduz a qualidade de vida da população. Objetivo Identificar o padrão de atividade física e os fatores associados em adultos de 20 anos ou mais. Método Inquérito populacional, transversal, com 600 indivíduos entrevistados em seus domicílios. Foram coletados os seguintes dados: aspectos demográficos, socioeconômicos, comportamentais, do trabalho e nível de atividade física. Realizaram-se as análises descritiva e bivariada e a regressão de Poisson. Resultados A prevalência de prática insuficiente de atividade física foi de 35% (IC 95%: 31,2-38,9). O nível educacional de 0 a 4 anos [RP = 2,35; IC95%: 1,07-5,15], o trabalho sentado [RP = 1,52; IC95%: 1,02-2,48] e o número de dias no computador [RP = 4,60; IC95%: 2,38-14,28] permaneceram no modelo final para o sexo feminino. Para o sexo masculino, permaneceram: o nível educacional de 0 a 4 anos [RP = 2,30; IC95%: 1,21-4,06] ou o de 5 a 8 anos [RP = 3,70; IC95%: 0,79-4,00], o trabalho sentado [RP = 2,22; IC95%: 1,36-3,62], o número de dias no computador [RP = 2,04; IC95%: 1,26-3,32] e o número de dias na TV [RP = 2,12; IC95%: 1,03-4,36]. Conclusão Houve elevada prevalência de prática insuficiente de atividade física e associação com nível de escolaridade, trabalho sentado e número de dias no computador e na TV.
