Lately, we’ve seen lots of good news about studies that show popular beverages are as good for us as they are good tasting and pleasant to drink. In this Drink to Your Health series, we’ll take a look at what health benefits research is finding for water, green tea, black tea, red wine, and other drinks.
Today, we take a look at coffee. Not long ago, coffee was considered an unhealthy drink, a guilty pleasure people indulge but apologized for with embarrassed remarks such as, “I know I really shouldn’t but … ” People who truly enjoyed coffee didn’t want to give it up, no matter what the prevailing health theories said at the time.
But in the last few years, coffee has been transformed from villain to bystander to good guy.
Now research shows those java-licious cups of Joe are loaded with antioxidants that help protect against many diseases including:
- type 2 diabetes
- cancers (several types)
- cardiovascular problems
- Parkinson’s disease
- Alzheimer’s disease and other dementias
- liver disease
And the latest study shows people who drink coffee every day live longer than those who don’t. The study started in 1995 with approximately 400,000 people aged 50 to 71 who did not have heart disease, stroke at that time. Also excluded were people whose daily calorie intake too high or too low.
When people who drank just one cup of coffee each day were compared to people who drank none, the coffee drinkers were less likely to die by 5 percent in women and 6 percent in men.
Most coffee drinkers had two to three cups each day. Women in that group were 13 percent less likely to die; men were 10 percent less likely than coffee-abstainers to die.
The greatest difference was found in women who drank four to five cups of coffee daily. Their death risk was 16 percent lower.
They also noted that the chances of dying from heart disease, stroke, respiratory disease, diabetes, infections, injuries, and accidents was lower in coffee drinkers.
Why? Researchers don’t know yet.
And they also don’t have enough information at this point to say whether coffee was the cause of longer lifespan or merely an associated factor – or, to look at that question another way, If longevity is a car speeding down the highway, is coffee the driver of that car or merely a hitchhiker tagging along for the ride?
We won’t know for sure until more research is done, but for now it’s good to know that coffee lovers can relax and enjoy another cup of their favorite healthy brew.
