Data are presented as average ± standard deviation (SD). HS—high-salt; LS—low-salt; HS+C+E—high-salt + vitamin C + vitamin E; FRAP—ferric reducing ability of plasma; TBARS—thiobarbituric acid reactive substances; 8-iso-PGF2α—8-iso Prostaglandin F2α; CuZn SOD—copper zinc superoxide dismutase; GPx1—glutathione peroxidase 1. * p < 0.05 difference between the LS diet and HS diet or LS diet and HS+C+E diet within groups; † p < 0.05 difference between HS and HS+C+E groups.
