Coffee and tea may reduce the risk of serious liver damage in people who drink too much alcohol, are overweight or have too much iron in the blood, researchers reported yesterday.

The study of nearly 10,000 people showed that those who drank more than two cups of coffee or tea per day developed chronic liver disease at half the rate of those who drank less than one cup each day.

The study, conducted by the National Institute of Diabetes and Digestive and Kidney Diseases and Social & Scientific Systems Inc., found that coffee provided no protection to people at risk of liver disease from other causes, such as viral infections.
