Effects of quinoa on serum antioxidative parameters of rats fed a high-fat diet. A SOD activity. B GSH-PX activity. C GSH level. D MDA level. NC: normal chow diet control group (n = 7); HF: a high-fat diet group (n = 7); HF + LQ: low-dose quinoa diet group (n = 7); HF + HQ: a high-dose quinoa diet group (n = 7). The rats in the NC group were fed a standard diet, and the rats in the other three groups were fed an HF diet. Simultaneously, low-dose quinoa feed (HF + LQ) was added to 9% quinoa (equivalent to 100 g of daily human intake), and high-dose quinoa feed (HF + HQ) was added to 27% quinoa (equivalent to 300 g of daily human intake). *p < 0.05 vs. the NC group, **p < 0.01 vs. the NC group; ^Δp < 0.05 vs. the HF group, ^ΔΔp < 0.01 vs. the HF group; ^#p < 0.05 vs. the HF + LQ group; ^##p < 0.01 vs. the HF + LQ group. The bars show the mean values with standard deviations
