Downing a beer a day alters the structure of fibrinogen, a blood protein active in clotting. The preliminary finding by an international research team could be good news for people with artery-narrowing atherosclerosis. They might be able to diminish their risk of heart attacks and strokes by routinely lifting a mug.
For their investigation, Shela Gorinstein of the Hebrew University–Hadassah Medical School in Jerusalem and her colleagues recruited 48 men who had just recovered from coronary-artery-bypass surgery. Half received 12 ounces of pale lager every day for a month; the rest got an equivalent amount of mineral water. All participants ate a roughly 1,700-calorie daily diet rich in fruits, vegetables, and olive oil.
