Research published in the Proceedings of the National Academy of Sciences (Proc. Natl. Acad. Sci. USA, 10.1073/pnas.0500998102) examined the effect of pomegranata juice on the progression of atherosclerosis in iice, finding that hypercholesterolemic mice that drank the pomegranate juice reduced the progression of atherosclerosis (plaque buildup) by 30%. The researchers also found that heart cells treated with the juice had a 50% increase in nitric oxide production. According to a HealthDay news article on Yahoo (http://story.news.yahoo.com/news?tmpl=story&cid=97&e=1&u=/hsn/pomegranatejuicecutscardiovascularrisks), the equivalent amount of pomegranate juice in humans would be approximately 16 ounces daily.
