Coffee May Prevent Parkinson's Disease: Shake Now Instead of Later by Dr. Mark V. Wiley

Although I try to be health-conscious, especially given the number of food-triggers there are for migraines (which I used to suffer), I have always been and will forever be held captive to coffee. That's right, folks, I admit it. I adore dark-roasted, freshly ground, well-brewed coffee. And, dare I say it, with cream and sugar!

As with so many foods and activities, first they say it's good and then, a few years later, it's bad for us. Not only, they say, can the caffeine in coffee cause excess stress and tension in the body, giving many the jitters and others serious headaches, it also acts as a diuretic, leading to dehydration and constipation.

And whereas the medical community first praised the value of dairy products, placing them among the priorities of a well-balanced diet, they have now discovered that too much dairy intake can cause prostate cancer in men!

The reverse is true of coffee. What was once scorned as the drink of legal stimulant addicts has now been found to prevent Parkinson's disease in some men.

The Study
The results of a 30-year longitudinal study on the effects of coffee on Parkinson's disease were recently published in the May 24/31 1999 issue of the Journal of the American Medical Association (JAMA). The study, which analyzed the health of 8004 Japanese-American men (aged 45-68 years), explored the association of coffee and caffeine intake with the risk of Parkinson's disease. 

According to JAMA , 102 of the men became afflicted with Parkinson's. Adjusted for age, incidence of the disease declined consistently with increased amounts of daily coffee intake, from 10.4 per 10,000 person-years in men who drank no coffee to 1.9 per 10,000 person-years in men who drank at least 28 oz. The study thus indicates that higher coffee and caffeine intake is associated with a significantly lower incidence of Parkinson's disease.

The Parkinson's-Coffee Connection
Actor Michael J. Fox, U.S. Attorney General Janet Reno, Pope John Paul II, and perhaps someone you personally know all struggle with Parkinson's disease. It afflicts male and female alike, both young and old. And until recently, there has been no cure or preventive measure in sight.

According to the New England Journal of Medicine , Parkinson's disease afflicts 3% of the population older than 65 years and is a significant source of morbidity and health services use. And according to the Journal of the American Medical Association, while rare genetic forms of the disease do exist, determinants of typical late-onset disease appear to be largely environmental. And while no treatment has definitively been shown to prevent the disease or slow its progression, coffee intake has been inversely associated with Parkinson's occurrence in some studies, such as that of the Honolulu Heart Program, published in a 1994 issue of the American Journal of Epidemiology , which found that coffee intake measured prospectively appeared to be protective against affliction with Parkinson's.

In the Honolulu study, coffee drinkers had significantly lower incidence of Parkinson's disease than abstainers. And at each examination of the participants over the 30 year course of the study, larger amounts of coffee intake were associated with a greater decline in incidence of the disease. In short, non-drinkers of coffee had a 5 times greater chance of contracting Parkinson's than men who drank at least 28 oz. of coffee per day.

You see, coffee can be good for you. And for those health-conscious decaf drinkers, you're out of luck. The study showed that no other single attribute of coffee-such as niacin, sugar, milk, water-assisted in lowering incidence of the disease-only 100% pure caffeinated coffee.

As an aside, an earlier article by Yano and Kagan from the Honolulu Heart Program published in the New England Journal of Medicine shows no relationship between coffee drinking and risk of coronary artery disease! 

The Last Drop
The biology supporting why a beverage that gives drinkers the jitters would be helpful in combating Parkinson's disease is still unknown. Some researchers hypothesize that regular caffeine consumption may counteract the brain's age-related degenerative process that leads to loss of dopamine, a key factor in Parkinson's onset. Of course, the study does not guarantee that all men who drink coffee will be protected from this debilitating disease. And so far, no such longitudinal studies have yet been carried out on women.

So go ahead and drink the super-strong, high octane leaded stuff that looks like oil sludge. While it may give you the shakes now, it just might help you avoid them later.
