Of the 808 patients who responded to the questionnaire at baseline, 711 drank zero
to 2 cups
of coffee a day, and 97 drank 3 or more cups
of coffee daily. Those who drank the most coffee also consumed the most alcohol and cigarettes. These coffee drinkers, however, had healthier livers than the other participants, with less steatosis (evaluated by biopsy) and lower bilirubin levels, α-fetoprotein levels, and aspartate aminotransferase/alanine aminotransferase ratios (P < .05).
