Coffee and tea consumption linked to various health benefits

Overview

Research through September 2026 continues to link regular coffee and tea consumption to lower rates of liver disease, cardiovascular events, and overall mortality. Large-scale cohort analyses demonstrate a dose-response relationship where drinking five or more cups daily can reduce hepatocellular carcinoma risk by up to 47% and liver-related mortality by approximately 42%. Recent meta-analyses involving over 2.2 million people suggest that consuming two additional daily cups of coffee is linked to a 35% lower risk of hepatocellular carcinoma and a 44% reduction in cirrhosis risk. Studies involving approximately 355,000 participants from the UK Biobank suggest these protective qualities may stem from caffeine, polyphenols, and chlorogenic acids, which help reduce inflammation and liver scarring. Regarding mental health, a study in the Journal of Affective Disorders utilizing UK Biobank data from 461,586 participants identified a ‘J-shaped’ relationship between coffee intake and mental health. A ‘golden mean’ of two to three cups daily is associated with a lower risk of depression, anxiety, and stress. However, excessive consumption of five or more cups daily is linked to a higher risk of mood disorders. Nutritionist Morgan L. Walker noted that exceeding moderate limits may trigger anxiety, restlessness, and poor sleep. Newer findings suggest that regular, moderate consumption of caffeinated coffee or tea may also be linked to a lower risk of developing dementia and better cognitive aging. While caffeine is known to improve alertness by blocking adenosine receptors, researchers noted that previous studies faced challenges such as short follow-up periods and failure to distinguish between caffeinated and decaffeinated options. Additionally, black coffee without added sugar may assist in weight management due to its high concentration of antioxidants and negligible calorie content.
