Drinking a moderate amount of coffee -- about two 8-ounce cups a day -- may not be linked with increased cardiovascular risk, a European non-profit says. The Institute for Scientific Information on Coffee -- comprised of several major European coffee companies -- said a review of recent studies indicates for most healthy people, moderate coffee consumption was unlikely to adversely affect cardiovascular health. Furthermore, a study published earlier this year found green tea and coffee consumption resulted in reduced risk of stroke incidence in the Japanese population, the organization says. A wider body of evidence indicates the impact of coffee on cholesterol is dependent on the brewing method -- unfiltered coffee raises serum cholesterol levels whereas, but this is not the case with filtered coffee because the cholesterol-raising compounds in coffee are retained in the paper filter, the ISIC says.
