Beverages Rich in Resveratrol and Physical Activity Attenuate Metabolic Changes Induced by High-Fat Diet

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) (p < 0.0001). The grape juice group (GJG) (39.1 ± 7) had a higher number of microbiota bands DNA when compared to the other groups (p = 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) (p = 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 (p = 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.
