Consumption of saturated fat causes deleterious effects on health, which could be minimized through physical activity and foods with functional characteristics consumption. The aim of the study was to evaluate the beverage rich in resveratrol consumption and physical exercise in gut microbiota, body composition, lipid peroxidation, interleukin-6 (IL6) concentration and systolic blood pressure (SBP) of rats to the high-fat diet. Wistar rats were fed with control diet, high-fat diet (HFD), HFD and 15 mL solution of resveratrol, HFD and 15 mL of grape juice, HFD and 10 mL of red wine. All animals performed the physical training protocol five days a week. Grape juice and red wine composition were analyzed, SBP, body mass, consumption, adiposity and body composition, gut microbiota, lipid peroxidation and inflammation were evaluated. The grape juice (114.8 ± 22.5 mmHG) and red wine (129 ± 15.8 mmHg) groups showed lower SBP when compared to HFD (216.8 ± 20.6 mmHg) ( < 0.0001). The grape juice group (GJG) (39.1 ± 7) had a higher number of microbiota bands DNA when compared to the other groups ( = 0.002). The GJG (33.7 ± 6.7 pg/mL) presented lower concentration IL6 when compared to high-fat group (47.3 ± 16 pg/mL) ( = 0.003). GJG (4.7 ± 1.2 nmol/L) presented a lower concentration of TBARS when compared to control group (6.1 ± 1.4 nmol/L) and resveratrol group (6.6 ± 0.9 nmol/L), and the red wine group (7.4 ± 1.2 nmol/L) had a higher concentration of TBARS when compared to control group and GJG ( = 0.0001). The consumption of these beverages, especially grape juice, together with physical exercise, was able to promote beneficial changes even in the presence of a HFD.
饱和脂肪的摄入对健康有害,而通过体育活动和摄入具有功能特性的食物可以将这种危害降到最低。本研究旨在评估富含白藜芦醇的饮料和体育锻炼对高脂肪饮食大鼠肠道微生物群、体成分、脂质过氧化、白细胞介素-6(IL6)浓度和收缩压(SBP)的影响。Wistar 大鼠分别给予对照饮食、高脂肪饮食(HFD)、HFD 和 15ml 白藜芦醇溶液、HFD 和 15ml 葡萄汁、HFD 和 10ml 红酒。所有动物每周进行 5 天的体育训练。分析葡萄汁和红酒的成分,评估 SBP、体重、摄食量、肥胖程度和体成分、肠道微生物群、脂质过氧化和炎症。与 HFD(216.8±20.6mmHg)相比,葡萄汁(114.8±22.5mmHg)和红酒(129±15.8mmHg)组的 SBP 较低( < 0.0001)。与其他组相比,葡萄汁组(GJG)(39.1±7)的肠道微生物群 DNA 条带数量更高( = 0.002)。与高脂肪组(47.3±16pg/mL)相比,GJG(33.7±6.7pg/mL)的 IL6 浓度较低( = 0.003)。与对照组(6.1±1.4nmol/L)和白藜芦醇组(6.6±0.9nmol/L)相比,GJG(4.7±1.2nmol/L)的 TBARS 浓度较低,而与对照组和 GJG 相比,红酒组(7.4±1.2nmol/L)的 TBARS 浓度较高( = 0.0001)。即使在高脂肪饮食的情况下,这些饮料(尤其是葡萄汁)的摄入结合体育锻炼,也能促进有益的变化。
