¹Significant values of overweight and obese vs control;

²Significant values of obese vs overweight group. Comparison of the means was evaluated by ANOVA. SOD: Superoxide dismutase; CAT: Catalase; GSH-Px: Glutathione peroxidase; GSSG-R: Glutathione reductase; GSH: Reduced glutathione concentration.
