DYK #11: Drinking coffee – healthy or health hazard?
Did you know…
That drinking coffee can reduce the risk of having a stroke in women?
Swedish researchers followed a group of 34,670 women (ages 49-83) for about 10 years (all were free of cardiovascular disease or cancer in 1997). They were sorted into subgroups: a group that drank less than one cup of coffee a day, and groups that drank 1-2 cups a day, 3-4 cups a day and a group that drank 5 and more cups a day.
During those 10 years, they documented 1,680 strokes: 1,310 cerebral infarctions/ischemic strokes (caused by blockages), 154 intracerebral hemorrhages (caused by bleeding inside the brain), 79 sub-arachnoid hemorrhages (caused by bleeding on the surface of the brain) and 137 unspecified strokes.
Now you may wonder, “aren’t there a whole bunch of other factors that could influence the risk of stroke”? The researchers, too, considered this, and controlled their results on other risk factors: smoking status, Body Mass Index, history of diabetes, hypertension and alcohol consumption. However, the effect of coffee remained uninfluenced by those factors: coffee consumption was associated with a statistically significant lower risk of total stroke, cerebral infarction and sub-arachnoid hemorrhage.
Their theory is that coffee reduces the risk of stroke because it improves insulin sensitivity (a hormone that regulates carbohydrate and fat metabolism in the body).
Cup of coffee, anyone? How do you prefer your coffee? Black? With sugar?
I prefer latte, personally, and I drink maybe 1-3 cups a day. But I love tea even more so!
