A recent study conducted by researchers from the U.S. National Institute of Diabetes and Digestive Kidney Diseases and from Social & Scientific Systems, Inc, suggests that drinking two cups of coffee or tea a day may help reduce the risk of chronic liver disease in people with high risk of liver disease due to heavy drinking, obesity, diabetes, or iron overload. By analyzing 19 years of data on nearly 10,000 people, the researchers found that people who drank more that two cups or coffee or tea a day developed chronic liver disease half as often as people who consumed less then a cup of coffee or tea a day.
