[Nubella News] - Go ahead, drink that coffee, and don't worry about the effect it'll have on your heart. Just keep in mind the warnings.

Researchers looking at two studies of 120,000 java fans over 20 years said they found no link between excessive coffee drinking and heart disease - and they're talking about six or more cups of coffee a day. In fact, these coffee drinkers have a slightly lower risk of heart disease than men who drank a cup or less of coffee a day.

But don't go rushing out to your favorite coffee bar just yet.

Researchers at the Harvard School of Public Health warn that some people may carry a gene responsible for metabolism of coffee's caffeine, which puts them at higher risks for heart disease. In addition, the study didn't include unfiltered coffee, which studies show packs much more of a caffeine wallop than the American versions and raises artery-clogging "bad" cholesterol.

Coffee drinkers and other bad habits

In the study, the researchers found that heavy coffee drinkers also were more likely to drink alcohol and smoke, and less likely to exercise and take vitamin consumption, all of which could affect heart health. But the scientists adjusted their risk estimates to take those bad health habits into consideration.

Other results of the study, which appears in April's Circulation journal, show:

• No difference in heart risk between women who frequently drank decaffeinated coffee and those who did not.

• No significant difference in total cholesterol, "good" and "bad" cholesterol in fans of caffeinated or decaffeinated coffee.

• Type 2 diabetes, which generally develops later in life, had no effect on heart-disease risk associated with drinking coffee.

The researchers also warned that coffee fans who have problems falling asleep are probably drinking too much. They also urged women who are pregnant or nursing to limit their coffee consumption to three or fewer eight-ounce cups of coffee day to keep from making the fetus or infant sensitive to caffeine.
