INTRODUCTION Oxidative stress, caused by excessive reactive oxygen species produced as the result of physiological aerobic metabolism of animals, can lead to the onset of various diseases, such as cancer, hypertension, diabetes, and atherosclerosis (Zelko et al., 2002; Rosenblat et al., 2008). The occurrence of all these diseases is related to blood metabolites, including total cholesterol (TCHO), triacylglycerols (TG) and glucose (GLU), and to the oxidation of TCHO in humans (Liu et al., 1992). In particular, low-density lipoprotein cholesterol (LDL-C) has been shown to be closely related to the pathogenesis of human atherosclerosis (Steinberg and Witztum, 2002).
