Possible Health Benefits of Coffee
Guilt by Association
Coffee has not been proven to cause all these benefits, but it is associated with them. One way coffee might be helpful is that a cup contains more antioxidants, including chlorogenic acid, than a serving of vegetables. Up to five cups a day seems to have benefit.
Coffee is associated with lower incidence of the following:
skin (including the worst type, melanoma), liver, prostate, mouth, pharyngeal (throat), uterine (womb) and colon cancer
an aggressive (ER-negative) type of breast cancer
stroke, heart attack and other inflammatory conditions
only in low doses, suicide (High consumption of coffee increases suicide risk.)
brain tumor, including the worst kind, glioma
death (all-cause mortality)
depression in women
kidney disease in women
cirrhosis of the liver
Caffeine has long been known to boost the effectiveness of painkillers and is included in many of them. Researchers are now looking at caffeine as a painkiller in its own right.
And here's a proven benefit: the chlorogenic acid in coffee improves blood vessel function at one and five hours after drinking it.
I drink my coffee happily - 2 to 5 cups per day. My doctor would probably recommend my stopping if I had one of the following conditions:
anxiety disorder or insomnia
stomach ulcer or reflux
certain kinds of kidney stones
too rapid heart rate
irritable bowel syndrome
Here's a final note: If you stop drinking coffee all at once instead of tapering off, you may notice fatigue and a headache.
Check with your doctor for your individual best use of coffee.
