RESUMO
OBJECTIVE: To assess changes in daily habits, food choices and lifestyle of adult Brazilians before and during the COVID-19 pandemic. DESIGN: This observational study was carried out with Brazilian adults through an online questionnaire 5 months after the social distance measures implementation. The McNemar, McNemarBowker and Wilcoxon tests were used to investigate differences before and during the COVID pandemic period, adopting the statistical significance of P < 0·05. SETTING: Brazil. PARTICIPANTS: Totally, 1368 volunteers aged 18+ years. RESULTS: The volunteers reported a lower frequency of breakfast, morning and lunch snacks (P < 0·05) and a higher frequency of evening snacks and other meal categories during the pandemic period (P < 0·05). The results showed an increase in the consumption of bakery products, instant meals and fast food, while the consumption of vegetables and fruits decreased (P < 0·005). There was a significant increase in the frequency of consumption of alcoholic beverages (P < 0·001), but a reduction in the dose (P < 0·001), increased frequency of smoking (P = 0·007), an increase in sleep and screen time in hours and decrease in physical activity (P < 0·001). CONCLUSIONS: It was possible to observe an increase in screen time, hours of sleep, smoking and drinking frequency. On the other hand, there was a reduction in the dose of alcoholic beverages but also in the practice of physical activity. Eating habits also changed, reducing the performance of daytime meals and increasing the performance of nighttime meals. The frequency of consumption of instant meals and fast food has increased, while consumption of fruits and vegetables has decreased.

The intestinal microbiota, which is a complex and dynamic population of different bacterial species, represents an important contribution to the health of the host. This microbiota plays a key role by promoting the integrity of the epithelial barrier and the development of mucosal immunity. However, under some stressful situations, such as after gastrointestinal surgery, infectious complications may originate from the intestinal microbiota of the patient. This phenomenon is known as the gut origin of sepsis hypothesis. However, the supply of probiotics has beneficial effects under similar conditions despite some controversial results. Therefore, it is important to carefully assess the efficacy of probiotics in the prevention and treatment of complications in surgical patients and to evaluate the safety of its use. This review provides an overview of the proposed mechanisms of probiotic action and the significant progress in this field, mainly concerning gastrointestinal surgery.
