Read this over coffee
Go ahead: That cup of joe won't hurt you, the latest research says. It might even help you.Judy ForemanHealth SenseMay 18, 2009Coffee drinkers, rejoice! The heavenly brew, once deemed harmful to health, is turning out to be, if not quite a health food, at least a low-risk drink, and in many ways a beneficial one. It could protect against diabetes, liver cancer, cirrhosis and Parkinson's disease.What happened? Lots of new research, and the recognition that older, negative studies often failed to tease apart the effects of coffee and those of smoking because so many coffee drinkers were also smokers."Coffee was seen as very unhealthy," said Rob van Dam, a coffee researcher and epidemiologist at the Harvard School of Public Health. "Now we have a more balanced view. We're not telling people to drink it for health. But it is a good beverage choice."As you digest the news on coffee, keep in mind that coffee and caffeine are not the same thing. In fact, "they are vastly different," said coffee researcher Terry Graham, chairman of Human Health and Nutritional Sciences at the University of Guelph in Ontario, Canada. One can be good for you; the other, less so."Coffee is a complex beverage with hundreds, if not thousands, of bioactive ingredients," he said. "A cup of coffee is 2% caffeine, 98% other stuff."Before we rhapsodize further, a few caveats:Caffeine -- whether in coffee, tea, soft drinks or pills -- can make you jittery and anxious and, in some people, can trigger insomnia. Data are mixed on whether pregnant women who consume caffeine are more likely to miscarry. In general, 200 milligrams a day -- the amount in one normal-sized cup of coffee -- is believed safe for pregnant women, said Van Dam.For people with hard-to-control hypertension, a sudden, big dose of caffeine may boost blood pressure because caffeine constricts blood vessels. But decaf is fine in that respect. And even caffeinated coffee doesn't increase blood pressure much once you drink it for a week or so, said Van Dam. In fact, the caffeine in coffee seems to have less of an effect on blood pressure than the caffeine in colas because there are so many other substances in coffee that have the opposite effect physiologically from caffeine.One final caveat: The new research heralding coffee's health benefits is not perfect. Most of the studies are observational; that is, they followed people over time and correlated health outcomes with coffee drinking -- based on people's recollections of how much coffee they consumed. The studies don't prove that coffee was the cause of improved health outcomes. Still, the sheer volume of the research, and the fact that the conclusions line up so neatly, make it reasonably credible, researchers say.Diabetes: Twenty studies worldwide show that coffee, both regular and decaf, lowers the risk for Type 2 diabetes, in some studies by as much as 50%. 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.If, despite all this good news, you still worry you're drinking too much coffee, then cut back or quit. But don't go cold turkey. Abrupt caffeine withdrawal can trigger headaches, noted Dr. Alan Leviton, a neurologist at Harvard Medical School who consults for the National Coffee Assn., an industry group. So, taper off instead.On the other hand, if reading this makes you want an extra cup, go for it. And enjoy

Weekend crash leads to two collisions with passing motorists

As traffic slowed around a wreck along U.S. Highway 101 Saturday night, two traffic collisions occurred near the original incident, California Highway Patrol officials reported.
According to CHP Sgt. Doug Tupen, on Saturday night along Highway 101 north of Humboldt Hill Road, a driver reported to police they had been forced off the roadway and into a field along the highway by another driver.
A CHP officer responded to the scene and approached the vehicle, which was stopped in the field. At around 11:40 p.m., after the officer had been at the scene about 40 minutes, Tupen said a driver hauling a trailer approached the area. The truck driver reportedly diverted his attention to the wreck as he passed, allowing his vehicle to drift off the roadway and onto the highway shoulder. As the truck approached the CHP officer's patrol car parked on the roadside, the truck driver swerved to miss the car. According to Tupen, the truck did miss the CHP patrol car. However, the trailer struck the unoccupied patrol vehicle, spinning it 180 degrees.
The traffic officer was still at the scene of the original collision -- about 120 feet south of his patrol car -- and was not injured in the wreck.
Within two minutes, Tupen said another driver passing by the scene diverted their attention to the wreck and slammed into the car ahead as it slowed.
No one was injured in any of the collisions, and Tupen said so far, no citations have been issued, though the collisions remain under investigation by the CHP. Impairment was determined not to be a factor in the wrecks.

”This is why we like to encourage people to pay attention to their driving and not worry about what we're working on on the side of the road,” Tupen said. “This kind of collision is not uncommon. This is how most of our officers get seriously hurt or killed.”
