STEATOTIC LIVER DISEASE: THE IMPACT OF TEA AND COFFEE CONSUMPTION. LITERATURE REVIEW
Background. Globally, nonalcoholic fatty liver disease (NAFLD) affects more than one quarter of the adult population. It is characterized by excessive hepatic fat accumulation, associated with insulin resistance and defined as the histological presence of steatosis in >5% hepatocytes.
Objective. The purpose of this review is to study the influence of tea and coffee consumption on liver function in NAFLD.
Search Strategy. The following databases were used: Google Scholar, PubMed, and Scopus. We included articles written in English. The search keywords in PubMed are liver, coffee/tea, NAFLD. We included articles in the review published between 2017 and 2025, mostly at evidence levels A and B.
Research Results. According to numerous studies, regular coffee drinkers are far less likely to develop NAFLD, and those who have already been diagnosed with NAFLD are much less likely to develop liver fibrosis. Coffee drinkers who consume ≥3 cups/day of coffee are significantly associated with a reduced risk of liver-related hospitalizations. Moderate coffee consumption (three to five cups per day) is acceptable as part of a healthy diet.
Studies show that various types of tea protect hepatocytes from lipid toxicity by effectively improving the imbalanced lipid metabolism in the serum and liver tissue. The studies were conducted primarily in mice and showed some benefits related to liver function.
Conclusion. Moderate coffee consumption (3 cups per day) is recommended for patients with NAFLD to prevent the development of liver fibrosis. More research needs to be conducted to evaluate the effects of tea on people soon.
