  1. Values are means ± SEM; SOD, superoxide dismutase; GPx, glutathione peroxidase; MDA, malondialdehyde. *P < 0.05 represents a significant difference from soybean oil no salt group; #P < 0.05 represents a significant difference from canola oil no salt group; P < 0.05 represents a significant difference from soybean oil and canola oil no salt groups.
