Coffee. I've generally found that people either love it or hate it. For some reason, this bitter brew evokes strong emotions in some; usually more in the "I love coffee" realm than the other. Of course that's obvious by the abundance of coffee shops that litter the streets of most major cities and a smattering of them in the smaller towns.
Our very small town/village has a locally owned one that my husband managed and I worked at for 6 years. We really grew to love and appreciate the rich depths of flavor coffee has and also did some research on its possible benefits.
Benefits? That's right. Coffee does have some health perks that go along with it despite a lot of negative press in the past. More recent studies have shown that coffee can be helpful to your body.
Should everyone drink it? The purpose of this post is not to make you a coffee drinker as most people don't have to be "made" to love coffee. It just happens. Once it starts, coffee is not only a satisfying drink, but one that may just deliver a few helpful benefits as well. So if you already drink it or are just plain curious, here are a few things I learned...
It is important to note that most studies mostly show an association of coffee drinkers with these health benefits. They aren't direct "cause and effect studies" which show a direct correlation between coffee and the coffee drinker as other factors could affect the outcome of the study.
However, coffee has been with us now since before the 14th century when the Arabs learned how to cultivate and successfully trade the beans. That's a LONG time of usage and it helps to give us some insight into any long term effects of coffee even though most studies will say they "they still don't know the long term impact that coffee has on our health."
Caffeine is coffee's most obvious draw. That's a bit obvious. However, coffee has some other benefits besides caffeine that is now showing up in studies being done on coffee's decaf version.
Compared to non coffee drinkers:
"A growing body of research shows that coffee drinkers, compared to nondrinkers, are:
- less likely to have type 2 diabetes, Parkinson's disease, and dementia
- have fewer cases of certain cancers, heart rhythm problems, and strokes." 1
Diabetes?
"The vast majority of those studies have shown a benefit of coffee on
the prevention of diabetes. And now there is also evidence that
decaffeinated coffee may have the same benefit as regular coffee,” says Frank Hu, MD, MPH, PhD, nutrition and epidemiology professor at the Harvard School of Public Health. 2
"Hu calls the data on coffee and type 2 diabetes "pretty solid," based on more than 15 published studies." 3
How could coffee help keep type 2 diabetes at bay? It seems like it's a combination of its antioxidants and minerals such as magnesium and calcium which help the body use insulin which in turn regulates blood sugar.
Heart disease and stroke?
Well, when you lower the risk of diabetes, you automatically lower your heart risk...there's one way it helps.
"And, for women, coffee may mean a lower risk of stroke.
In 2009, a study of 83,700 nurses enrolled in the long-term
Nurses' Health Study showed a 20% lower risk of stroke in those who
reported drinking two or more cups of coffee daily compared to women who
drank less coffee or none at all. That pattern held regardless of
whether the women had high blood pressure, high cholesterol levels, and
type 2 diabetes." 4
Dementia?
According to a study done on clinical mice, coffee was shown to help boost the levels of GCSF (granulocyte colony stimulating factor), a growth factor that was shown to help fight off Alzheimer's Disease. 5
Certain Cancers?
"A Harvard School of Public Health study shows that men who drink six cups of coffee a day have a 60 percent decreased chance of developing a dangerous form of prostate cancer, as well as a 20 percent decreased chance of developing any other kinds of prostate cancer." 6
"New research presented at the American Association for Cancer Research conference shows that coffee could help to ward off basal cell carcinoma, (skin cancer) the most common cancer in the world." 7
These recent studies are sure to encourage coffee drinkers everywhere and make us sigh with a bit of relief when indulging in a cup of our favorite dark roast.
1. Just remember, these results are conducted on plain coffee only...no cream, sugar or syrups. Not that you can't still achieve some health benefits with them but to remember to go easy on the additives if you plan on getting the best results.
2. Also, if you have any sensitivities to caffeine in the coffee, try decaf instead.
3. Keep your coffee consumption reasonable and moderate. Four to seven cups are considered heavy usage (this can depend on your body size) and can lead to negative effects like sleeplessness, anxiety and irritability as well as other slight health risk factors.8 Listen to your body, it has its way of telling you when enough is enough.
So put on a big smile when you enter your next Starbucks or coffee house and know that a simple cup of coffee will not only make you a little more wide awake, but can help your body out just a bit too...
Blessings!
