Table 2 and Table 3 describe the associations of metabolic syndrome and dyslipidemia with the induction of OS and how, together, they affect certain pathologies. Notably, individuals with metabolic syndrome exhibit indications of increased oxidative damage, including diminished antioxidant defenses, reduced levels of vitamins such as vitamin C and α-tocopherol, decreased activity of antioxidant enzymes like superoxide dismutase, and elevated levels of markers such as malondialdehyde, protein carbonyls, and xanthine oxidase activity [130]. This evidence concerns the gene XDH and metabolic syndrome.
