Coffee and Tea Intake Appears Protective Against Chronic Liver Disease Slideset on: Ruhl CE, Everhart JE. Coffee and tea consumption are associated with a lower incidence of chronic liver disease in the United States. Gastroenterology. 2005;129:

clinicaloptions.com/hep Coffee/tea consumption and incidence of chronic liver disease Background and Rationale  Studies of liver enzymes suggest that coffee or caffeine consumption may reduce liver injury  Various international studies found higher coffee consumption to be associated with lower incidence of cirrhosis and cirrhosis-related death  Current study assessed relationship between coffee and tea consumption with incidence of chronic liver disease in general US population Ruhl CE, et al. Gastroenterology. 2005;129:

clinicaloptions.com/hep Coffee/tea consumption and incidence of chronic liver disease Study Design  National Health and Nutrition Examination Survey (NHANES I)— –Data included demographics; coffee, tea, or alcohol consumption; health status; and laboratory measures –Follow-up data identified hospitalizations, nursing home admissions, and deaths due to chronic liver disease  NHANES I Epidemiologic Follow-up Study (NHEFS)— –Data included more detailed information about caffeine consumption, health status (diabetes), and cigarette and alcohol use Ruhl CE, et al. Gastroenterology. 2005;129:
