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, McNemar–Bowker 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.

Anthocyanins are natural flavonoids, which belong to a group of polyphenols with antioxidant, anti-inflammatory, hypolipidemic and hepatoprotective activities. The aim of this systematic review is to answer the questions "What are the impacts of anthocyanins on inflammatory and oxidative mediators of NAFLD in vivo?" and "What are the possible molecular mechanisms involved in the effects of anthocyanins on NAFLD and hepatic steatosis?" The search was performed at PubMed, Scopus, Web of Science, and Embase databases, and the risk of bias was assessed by the SYRCLE tool. The data analysis was conducted following the PRISMA guidelines. Twenty-three studies performed in animal models evaluating the effects of anthocyanins in inflammatory and oxidative stress mediators in NAFLD were included and evaluated. The anthocyanins demonstrated potential positive effects on inflammation and oxidative stress (OS), in addition to reduced hepatic steatosis. The main results identified were a reduction in TLR, NF-κB, MCP-1/CCL-2, TNF-α, IL-6, and IL-1β in addition to an improvement in antioxidant defense with an increase in Nrf2, SOD, GSH, GPx and CAT and a reduction in OS. The findings from this review provide insights for the development of future studies with anthocyanins on liver health and inflammatory and oxidative parameters. PROSPERO (CRD42024502710).

Exhaustive and acute unusual physical exercise leads to muscle damage. Curcumin has been widely studied due to the variety of its biological activities, attributed to its antioxidant and anti‐inflammatory properties. Furthermore, it has shown positive effects on physical exercise practitioners. However, there is no literature consensus on the beneficial effects of curcumin in acute physical activities performed by sedentary individuals. Therefore, we systematically reviewed evidence from clinical trials on the main effects of curcumin supplementation on inflammatory markers, sports performance, and muscle damage during acute physical exercises in these individuals. We searched PubMed/MEDLINE, Scopus, Web of Science, and Embase databases, and only original studies were analyzed according to the PRISMA guidelines. The included studies were limited to supplementation of curcumin during acute exercise. A total of 5 studies were selected. Methodological quality assessments were examined using the SYRCLE’s risk‐of‐bias tool. Most studies have shown positive effects of curcumin supplementation in sedentary individuals undergoing acute physical exercise. Overall, participants supplemented with curcumin showed less muscle damage, reduced inflammation, and better muscle performance. The studies showed heterogeneous data and exhibited methodological limitations; therefore, further research is necessary to ensure curcumin supplementation benefits during acute and high‐intensity physical exercises. Additionally, mechanistic and highly controlled studies are required to improve the quality of the evidence and to elucidate other possible mechanisms. This study is registered with Prospero number CRD42021262718.

(1) Background: Exhaustive exercise can induce muscle damage. The consumption of nutritional compounds with the ability to positively influence the oxidative balance and an exacerbated inflammatory process has been previously studied. However, little is known about the nutritional value of curcumin (CCM) when mixed with whey protein concentrate (WPC). This study was developed to evaluate the effect of CCM-added WPC on inflammatory and oxidative process control and histopathological consequences in muscle tissue submitted to an exhaustive swimming test (ET). (2) Methods: 48 animals were randomly allocated to six groups (n = 8). An ET was performed 4 weeks after the start of the diet and animals were euthanized 24 h post ET. (3) Results: WPC + CCM and CCM groups reduced IL-6 and increased IL-10 expression in muscle tissue. CCM reduced carbonyl protein after ET compared to standard AIN-93M ET and WPC + CCM ET diets. Higher nitric oxide concentrations were observed in animals that consumed WPC + CCM and CCM. Consumption of WPC + CCM or isolated CCM reduced areas of inflammatory infiltrate and fibrotic tissue in the muscle. (4) Conclusions: WPC + CCM and isolated CCM contribute to the reduction in inflammation and oxidative damage caused by the exhaustive swimming test.
