What are ways to keep my liver in good health ?

Aerobic fitness: Don't share needles, abuse alcohol, take meds you don't need, or trust people who make "imported holistic herbal remedies" -- many of the latter are laced with poison. Stay trim, aerobics-focused physically fit. If your liver enzymes go up, work with your physician to find the cause. The common cause of livers going bad nowadays is sedentary lifestyles.
