Researchers say that is probably because chlorogenic acid, one of the many ingredients in coffee, slows uptake of glucose (sugar) from the intestines. (Excess sugar in the blood is a hallmark of diabetes.) Chlorogenic acid may also stimulate GLP-1, a chemical that boosts insulin, the hormone that escorts sugar from the blood into cells. Yet another ingredient, trigonelline, a precursor to vitamin B3, may help slow glucose absorption.
Heart disease and stroke: Recent studies suggest that frequent coffee consumption does not increase the risk of either condition. In fact, coffee might -- repeat, might -- slightly reduce the risk of stroke. A study published in March in the journal Circulation looked at data on more than 83,000 women older than 24. It showed that those who drank two to three cups of coffee a day had a 19% lower risk of stroke than those who drank almost none. A Finnish study found similar results for men.
For cardiovascular diseases other than stroke, there doesn't appear to be a preventive benefit from drinking coffee, but there is also no clearly documented harm; the studies looked at the effect of drinking up to six cups of regular coffee a day.
Cancer: Coffee research has come up empty here -- with one big exception: liver cancer. Research consistently shows a drop in liver cancer risk with coffee consumption, and there is some, albeit weaker, evidence that it may lower colon cancer risk as well.
Cirrhosis: Coffee seems to protect the liver against cirrhosis, especially that caused by alcoholism. It's not clear, either for cancer or cirrhosis, whether it's coffee or caffeine that may be protective.
Parkinson's disease: With this progressive, neurological illness, it's the caffeine, not coffee, that carries the benefit. No one knows for sure why caffeine protects. Several studies show that coffee drinkers, men especially, appear to have half the risk of Parkinson's compared with nondrinkers. Women also get a benefit, but only those who do not use post-menopausal hormones, said Dr. Alberto Ascherio, a professor of epidemiology and nutrition at the Harvard School of Public Health. All it takes for a measurable reduction in Parkinson's risk, he said, is about 150 milligrams a day, the amount in an average cup of coffee.
Athletic performance: It's clear that caffeine, not coffee per se, delivers the big boost here, said Graham, the researcher from Ontario. In fact, caffeine was once deemed a controlled substance by the International Olympic Committee. Caffeine is a powerful "ergogenic agent," meaning it promotes the ability of muscles to work. Studies show that caffeine boosts performance in both very short and very long athletic events, said Graham. It used to be thought that caffeine worked by stimulating the release of sugar (glycogen) in muscles, but recent research suggests it helps muscles release calcium, allowing muscles to contract with more force. It takes only a medium cup of regular coffee for a 130-pound athlete to see a measurable improvement in performance, Graham added.
One last bit of coffee advice: Beware of unfiltered coffee -- the kind that is popular in Scandinavia and is made in French presses. Filtered coffee, which most Americans drink, is much better because the paper filters catch a substance called cafestol, which boosts "bad" cholesterol (LDL). Filtered coffee has no effect on either good or bad cholesterol.</blockquote>Bonus: quotes from Rob Van ***! (but not that one, apparently)
