Similarly, Kim et al. [48] also showed no effect on SOD, but observed significantly higher glutathione peroxidase among women with obesity who consumed black rice meal replacements for six weeks compared to white rice meal replacements (15.36 ± 5.63 U/g Hb vs. 3.52 ± 5.41 U/g Hb, p < 0.05). The gene discussed is GSTM1; the disease is obesity disorder.
