*4.1.1 Catechins*

Oolong tea polyphenols markedly inhibited the formation of oxidized lipids, reduced body fat and the risk of developing arteriosclerosis [42]. A double-blind placebo-controlled study by Sakata et al. (2013) demonstrated the health benefits of green tea extracts for NAFLD [43]. The green tea polyphenols showed higher bioavailability in the serum following its consumption. Antioxidant, anti-inflammation, lipid metabolism-related biomarkers, as well as SREBPs and related genes, are critical mediators of NAFLD. Epigallocatechin-3-gallate (EGCG), a critical bioactive from green tea, prevented NAFLD in several experimental models (**Table 1**) [57].
