Coffee

Researchers at the National Cancer Institute said people who drink coffee every day are doing well by their livers, improving the organ's function and potentially staving off disease.
In a recent health survey, scientists found those who drink coffee -- both decaf and regular -- were less likely to have high levels of various biomarkers that signal poor liver function, including aminotransferase, aminotransferase, alkaline phosphatase and gamma glutamyl transaminase.
