Coffee lovers who quit drinking caffeinated filtered coffee reduce their blood levels of homocysteine and cholesterol, according to a new study by researchers from Ullevål University Hospital and the University of Oslo, Norway (Am J Clin Nutr. 2001;74:302-307).
Scientists have long debated whether coffee increases the risk of heart disease. The implications of previous research that found that a very high intake of boiled (unfiltered) coffee increases these heart-unfriendly substances were unclear for people who consume filtered coffee, because unfiltered coffee contains larger amounts of the organic compounds found in coffee grounds, including terpenoids, which are known to boost cholesterol levels.
