Arecent clinical study demonstrated a possible connection between coffee consumption and heart health. the researchers performed a 6-week trial with 191 individuals, all of whom were heavy coffee drinkers (average of 5 cups/day) prior to the experiment, but none of whom were smokers. they divided the 191 participants into three groups: no coffee consumption, 1-3 cups/day, and 4 or more cups/day. they measured blood levels of cholesterol and homocysteine as indicators of heart health. only the no-coffee group showed a significant drop in both indicators. previous studies had demonstrated that decreases of the magnitude observed in the no-coffee group could cut the incidence of heart disease by 10-15%.
