INTRODUCTION: Red wine consumption is considered to be protective against oxidative stress. Diet strongly influences non-alcoholic fatty liver disease, which is associated with oxidative stress and is considered the hepatic manifestation of the metabolic syndrome. METHODS: We reviewed the available evidence that investigated the effects of red wine on the postprandial-induced metabolic and oxidative stress in humans. RESULTS: After red wine consumption with meal, despite the improvement in non-enzymatic antioxidant capacity and lipoperoxidation markers, the influence of confounding factors such as uric acid should be taken into account. Both uric acid and triglycerides increases, induced by ethanol, could cause liver damage. On the other hand, further researches are required in order to understand the meaning of the induction of antioxidant enzymes by red wine and red wine polyphenols in the context of non-alcoholic fatty liver disease. CONCLUSION: In conclusion, inconsistent and contrasting findings exist regarding the potential benefits of red wine consumption against postprandial stress.
