Drinking green tea regularly may improve liver health markers, especially in people with steatosis, according to dietitians cited by Rynek Zdrowia.
The liver clears harmful substances from the blood, helps process nutrients, produces bile to digest fats and helps maintain normal glucose and cholesterol levels. Researchers have long studied green tea for its plant compounds, particularly catechins and epigallocatechin gallate, known as EGCG, which can reduce oxidative stress, affect inflammation and help regulate fat metabolism in liver cells.
Effects on fatty liver disease
Dietitian Johanna Kats said one thing that can happen when people drink green tea is an improvement in liver health markers, especially among those with non-alcoholic fatty liver disease, a condition linked to obesity, type 2 diabetes or high triglyceride levels.
Kats added that green tea contains catechins, including EGCG, which may support antioxidant defenses, regulate inflammation and support fat metabolism in the liver.
Enzyme levels and long-term risk
Dietitian Malina Malkani said liver enzyme levels, a key marker of organ health, can drop within weeks of regular green tea consumption, a sign that liver inflammation is easing. She said this effect is usually seen in people who drink three to four cups of tea daily.
Malkani said people who drink green tea daily for months or years are less likely to develop fatty liver disease and liver cancer, likely due to the tea's antioxidant content and its long-term effect on liver inflammation.
Specialists stressed that tea alone will not solve the problem, and pointed to other habits including a diet low in processed foods, regular physical activity and limited alcohol intake.
