Coffee and Health

coffee and your health

 

According to an American report in 2004, if you are looking for something that could lower your risk of contracting diabetes, Parkinson's disease and colon cancer, plus something that could lift your mood and treat headaches, and lower your risk of having tooth cavities – you need look no further than your coffee pot!*

Coffee, the much maligned and well loved beverage, is making headlines for possibly cutting the risk of a number of diseases, and the real good news seems to be that the more you drink, the better.

After analysing data on 126,000 people in America over an 18 year period, Harvard researchers have calculated that drinking one to three cups of fresh coffee daily can reduce diabetes risk by single digits. But amazingly it appears that having six cups or more each day slashed men's risk by 54% and women's by 30%!

Though the scientists give the customary "more research is needed" before they recommend you do overdose on Cappuccino, their findings are very similar to those of a less-publicized Dutch study, and perhaps more importantly, it's the latest in a series of hundreds of studies suggesting that coffee may be something of a health food -- especially in higher amounts.

In recent decades, some 19,000 studies have been done examining coffee's impact on health, and for the most part, their results are very encouraging. 

"Overall, the research shows that coffee is far more healthful than it is harmful," says Tomas DePaulis, PhD, research scientist at Vanderbilt University's Institute for Coffee Studies (which conducts its own medical research and tracks coffee studies from around the world). "For most people, very little bad comes from drinking it, and a lot of good."

At least six studies indicate that people who drink coffee on a regular basis are up to 80% less likely to develop Parkinson's, with three showing the more they drink, the lower the risk. Other research shows that, compared to not drinking coffee at all, at least two cups daily can translate to a 25% reduced risk of contracting colon cancer, an 80% drop in liver cirrhosis risk, and nearly half the risk of having gallstones.

Coffee even offsets some of the damage caused by other vices, some research indicates. "People who smoke and are heavy drinkers have less heart disease and liver damage when they regularly consume large amounts of coffee compared to those who don't," says DePaulis.

There is also some evidence that coffee may help manage asthma - and even control the onset of attacks when medication is unavailable. It can also stop a headache, boost your mood, and even prevent teeth cavities.

Is it the caffeine? Is it the stack of antioxidants in coffee beans, some of which become especially potent during the roasting process? Or is it other mysterious properties that produce these health giving effects?

Actually, the answer is ‘yes’ to all.

Some of coffee's reported benefits are a direct result of its higher caffeine content: An eight ounce cup of drip-brewed coffee contains about 85 mg -- about three and a half times more than the same serving of tea or cola or one ounce of chocolate.

"The evidence is very strong that regular coffee consumption reduces risk of Parkinson's disease and for that, it's directly related to caffeine," says DePaulis,  "in fact, Parkinson's drugs are now being developed that contain a derivative of caffeine based on this evidence."

Caffeine can also help in treating asthma and headaches. Though not widely publicized, a single dose of ‘over the counter’ pain reliever contains up to 120 milligrams of caffeine – about the same as in a large mug of Espresso.

Boost to Athleticism

It's also caffeine that aids athletic endurance and performance, reports physiologist and longtime coffee researcher Terry Graham, PhD, of the University of Guelph in Canada. Such an aid in fact that, until recently, caffeine in coffee or other forms was deemed a "controlled" substance by the Olympic Games Committee, meaning that it could be consumed only in small, designated amounts by competing athletes.

"What caffeine seems to do is stimulate the brain and nervous system to do things differently", Dr Graham says, "that may include telling your body to ignore fatigue and encourage extra units of muscle for intense athletic performance. Caffeine may even have a direct effect on muscles themselves, causing them to produce a stronger contraction. But what's amazing about it is that unlike some performance-enhancing manipulation some athletes do that are specific for strength or sprinting or endurance, studies show that caffeine positively enhances all of these things."

“Whilst as little as one cup a day can offer some health benefit, the real impact comes from at least two or more”, says Dr.Graham.

It should be remembered, however, that the harder you exercise, the more benefit you may get from coffee. "Unfortunately, where you see the enhancing effects from caffeine is in hard-working athletes, who are able to work longer and somewhat harder," says Graham, who has studied the effects of caffeine and coffee for nearly two decades. "If you are a recreational athlete who is working out to reduce weight or just to feel better, you're not pushing yourself hard enough to get an athletic benefit from coffee (or any other caffeine products)."

And what about young people with growing minds and bodies? Coffee, as you probably know, makes you more alert and can assist concentration. But claims that it improves a child's academic performance can be exaggerated. Coffee-drinking youngsters may perform better in school tests because they're more awake, but most laboratory studies suggest that coffee doesn't really improve mental performance.

But it may help childrens' minds in another way. According to Dr DePaulis "There was recently a study in Brazil which found that children who drink coffee with milk each day are less likely to have depression than other children. In fact, no studies show that coffee in reasonable amounts is in any way harmful to children."

On the flip side, it's clear that coffee isn't for everyone. Its legendary ‘hit’ - if taken in excess (more than whatever your individual body can tolerate) - can increase nervousness, produce hand trembling, and cause rapid heartbeat. Whilst too much coffee may also raise cholesterol levels in some people and even contribute to artery clogging, most recent studies show no significant adverse effects on healthy people. Pregnant women, heart patients, and those at risk for osteoporosis may still be advised to limit or avoid coffee.

But you can get other benefits from coffee that have nothing to do with caffeine. "Coffee is loaded with antioxidants, including a group of compounds called quinines that, when administered to lab rats, increases their insulin sensitivity" says Dr Graham. “This increased sensitivity improves the body's response to insulin”.

This may explain why, in a new Harvard study, those people drinking decaffeinated coffee also showed a reduced diabetes risk, though it was only half as much as those drinking caffeinated coffee.

"We don't know exactly why coffee is beneficial for diabetes," says another researcher - Dr. Frank Hu - "it is possible that both caffeine and other compounds play important roles. Coffee has large amounts of antioxidants such as chlorogenic acid and tocopherols, plus minerals such as magnesium. All these components have been shown to improve insulin sensitivity and glucose metabolism."

Meanwhile, Italian researchers credit another compound called trigonelline, (which gives coffee its aroma and bitter taste), for having both antibacterial and anti-adhesive properties which may help prevent dental cavities from forming. 

In conclusion, therefore, it would appear that it is much better for your health to drink freshly brewed coffee than not at all.
