I wrote last year that coffee can help fend off liver damage. The latest recommendation from researchers is that the brew should flow through a filter.

Dr. David A. Johnson explained in a recent post on Medscape that coffee has long been known for its ability to slow the onslaught of liver disease. Recent studies show that brewed, filtered, caffeinated coffee has the best effect.

As coffee seeps through a filter, much of its kahweol and cafestol, organic compounds that raise cholesterol, remain with the grounds. The pot fills with a healthier brew.

Dr. Johnson recommends that people with hepatitis C be treated for their disease. While waiting for treatment they should drop alcohol entirely and replace it with at least three cups of coffee per day. He says he guarantees than none of your favorite coffee shops will ask for prior authorization.
