Coffee, it seems, has gotten a bad rap — blamed for heart problems, higher cholesterol, and hyperactivity. Now many researchers believe that not only is coffee not harmful, but it should be put in the category of health food. A study published Thursday in the journal Stroke finds that drinking coffee lowers stroke risk in women by 22 to 25 percent over a decade.

Perhaps it’s time for coffee to push aside green tea. “I think it’s actually more healthful than tea,’’ contends Dr. Frank Hu, professor of nutrition and epidemiology at the Harvard School of Public Health. As an investigator on the Harvard Nurses’ Health Study, Hu should know. He’s identified a connection between coffee consumption and lower diabetes risk.

In recent years, coffee drinkers have been found to have a reduced risk of gallstones, colon cancer, liver disease, and Parkinson’s. Long-distance athletes also have increased endurance if they drink coffee before a race.

Whether caffeinated coffee is safe to have during pregnancy remains uncertain. The latest research indicates that drinking as little as 200 milligrams of caffeine a day — equivalent to two cups of brewed coffee — doubles the rate of miscarriages. “The general consensus is that pregnant women should have less than this amount,’’ says Joan Salge Blake, a registered dietitian at Boston University.

And it’s probably a good idea for nursing mothers to stick to a limit of one or two cups a day as well, since excessive amounts of caffeine can pass into breast milk and cause behavioral changes in the baby.

But what about the rest of us?

The Swedish researchers who conducted the stroke study — in which nearly 35,000 women were followed for a decade after reporting their coffee intake on a 1997 dietary survey — say people shouldn’t take up a coffee habit based on these results. But, they add, the finding should ease concerns of those who fear that coffee drinking is harmful.

Women in the study who drank as little as one cup a day to more than five cups a day had a lower stroke risk than those who drank none. Oddly, it didn’t show that drinking four or five cups a day offered any greater protection than drinking just one, which raises some doubt about the strength of the finding.

Hu’s own diabetes research found that drinking three to four cups of coffee a day lowers the risk of type 2 diabetes by 20 percent and that drinking five or more cups lowers risk by 30 percent.

But “there’s still not enough data to make recommendations on how much people should drink,’’ Hu says. “It’s really an individual choice.’’ He does believe that coffee is healthful — so long as you avoid the whipped cream and sugar in those frothy blended concoctions.

Just how java delivers its nutritional benefits remains largely unknown, but it could be the significant amount of antioxidants and other disease-fighting chemicals contained in the coffee bean. These may lower levels of dangerous inflammation and may improve the action of the hormone insulin.

Also not known: whether decaffeinated coffee offers the same benefits. “Several studies suggest that,’’ says Hu, “but the evidence is limited.’’

That’s an important question to have answered because some people can’t tolerate caffeine. “They get jittery or can’t sleep at night, even if they only drink coffee in the morning,’’ says Blake.

Experts are also wary about recommending coffee for teens. “They need to be getting a good night’s sleep and not be wired,’’ Blake says.

Best pain reliever for the money?

When your knee acts up, which works better —Tylenol (acetaminophen) or Advil (ibuprofen)? What about when you have back pain? Consumer Reports has the answers on which painkiller works best — for the least money — for treating chronic pain caused by mild to moderate arthritis in a new report issued last week.

The most important, and no doubt most controversial, piece of advice? Most folks can skip the prescription drug Celebrex, which costs $76 to $199 a month. It works no better to relieve arthritis pain than generic ibuprofen or naproxen, which costs as little as $4 for a month’s supply.

Celebrex and other nonsteroidal anti-inflammatory drugs have risks when taken continuously for several weeks or months, such as gastrointestinal bleeding, stomach ulcers, and kidney failure, as well as high blood pressure, heart attack, and stroke. For this reason, Consumer Reports recommends taking Tylenol, which isn’t an NSAID, or its generic acetaminophen as a “first choice for most people who need relief from mild to moderate pain from osteoarthritis, headaches, and muscle pain.’’

Tylenol, while milder on the stomach, has been associated with liver problems, especially in those who take it with alcohol or who go over the recommended dose. D.K.

Should chewing tobacco be banned from baseball?

It’s collective bargaining time for Major League Baseball and players may be weighing in on whether to prohibit the use of chewing tobacco during televised games. The Campaign for Tobacco-Free Kids recently asked MLB to ban the practice; more than one-third of MLB players use smokeless tobacco products regularly.

“Kids idolize these players and imitate their every move,’’ says Danny McGoldrick, vice president of the Campaign for Tobacco-Free Kids. “This is one we don’t want them imitating.’’

Smokeless tobacco use among high school males — the primary users — has risen recently after being on a slight decline. Just how much of that increase can be attributed to modeling MLB players is unknown, says McGoldrick.

What’s firmly established is the habit’s risks: oral cancer, esophageal cancer, and pancreatic cancer, according to the National Cancer Institute, as well as heart disease and gum disease.

In a November letter to the Campaign for Tobacco-Free Kids, Michael Weiner, executive director of the MLB Players Association, said “the concerns . . . about the use of smokeless tobacco products . . . will be given a full airing with the membership.’’ D.K.
