A review of the therapeutic effects of polyphenols on non-alcoholic fatty liver disease: Focus on oxidative stress

Abstract

  A large amount of research suggests that polyphenols may have health benefits, particularly in metabolic disorders associated with obesity, such as non-alcoholic fatty liver (NAFLD), type 2 diabetes, and cardiovascular disease. Because of the importance of oxidative stress in the pathogenesis of metabolic disorders, great emphasis has recently been paid to the characteristics of polyphenols in obesity-related problems. This narrative review summarizes the current knowledge on the inhibitory effects of polyphenols, including curcumin, resveratrol, baicalin, nobiletin, and quercetin, on oxidative stress by focusing on the role of the Nrf2 pathway. This review gathered the data of the articles showing that the aforementioned polyphenols improve health in metabolic diseases via regulating Nrf2 and its target proteins involved in ameliorating oxidative stress. However, due to the limitations of in vitro and in vivo investigations, as well as lack of long-term human clinical trial trials studies, further high-quality research is required to definitively show polyphenols’ clinical usefulness for the prevention and management of NAFLD.
