PPARA and metabolic dysfunction-associated steatotic liver disease: In short, green, black, and dark teas, as well as tea polyphenols, could alleviate NAFLD through improving liver function, regulating glucose and lipid metabolism, decreasing the levels of ROS and inflammatory cytokines, and modulating the composition of gut microbiota (Table 1), with decreasing the expression of miR-34a, increasing the expression of miR-194, and upregulating SIRT1, PPAR-α, and AMPK signaling pathways (Figure 2).
