NEW YORK: Drinking coffee can help ward off type 2 diabetes and may even help prevent certain cancers, according to panelists discussing the benefits -- and risks -- of the beverage at a scientific meeting.
“We're coming from a situation where coffee had a very negative health image,” Dr. Rob van Dam of the Harvard School of Public Health, who has conducted studies on coffee consumption and diabetes, told Reuters Health. Nevertheless, he added, “it's not like we're promoting coffee as the new health food and asking people who don't like coffee to drink coffee for their health.”
Van Dam participated in a “controversy session” on coffee at the Experimental Biology 2007 meeting under way in Washington, D.C.
Dr. Lenore Arab of the David Geffen School of Medicine at UCLA also took part, presenting results of a review of nearly 400 studies investigating coffee consumption and cancer risk.
There's evidence, Arab noted, that the beverage may protect against certain types of colon cancer, as well as rectal and liver cancer, possibly by reducing the amount of cholesterol, bile acid and natural sterol secretion in the colon, speeding up the passage of stool through the colon and via other mechanisms as well.
However, Arab did find evidence that coffee may increase the risk of leukemia and stomach cancer, with the case for leukemia being strongest.
