Chen YP, et al. - Researchers conducted this systematic review and a dose-response meta-analysis to investigate the impact of coffee on nonalcoholic fatty liver disease (NAFLD) risk and its potential dose-response trends. Up until April 10, 2018, they searched the PubMed, Web of Science, MEDLINE, Cochrane, and Embase databases for relevant studies. A total of 7 eligible articles with 4,825 cases and 49,616 non-cases were identified. According to the findings obtained, consumption of > 3 cups of coffee were observed at a lower risk of NAFLD than < 2 cups per day. While the risk of NAFLD was inversely related to coffee consumption, the relevance may not be very close.
