Drinking more than a cup of coffee day is associated with between 22 and 25 percent lower risk of stroke compared with those who make less, according to a study by the National Institute of Environmental Medicine at Karolinska Institute in Stockholm (Sweden), which is published in the journal Stroke: Journal of the American Heart Association. "
low consumption or no consumption was associated with an increased risk of stroke in a study of 34,670 women between 49 and 83 years who were followed for an average of 10.4 years. Researchers say that although it is too early to change the habits of coffee drinkers, the study could reduce the concerns of some women.
groups of women who reported drinking one to two cups a day, three or four cups or more of five showed similar benefits compared with those who drank less than one cup a day to day. These differences were maintained regardless of smoking, body mass index, history of diabetes, hypertension, alcohol consumption, suggesting that the effects of coffee are not influenced by known cardiovascular risk factors. Researchers collected
data from the Swedish Mammography Group that investigated the association between diet, lifestyle and disease development. The authors collected cases of first stroke occurred between January 1998 and December 2008 by linking the Swedish based hospitals to document a total of 1,680 strokes. As pointed
Susanna Larsson, author of the study, after taking into account other risk factors, coffee consumption was associated with a lower risk of total stroke, stroke and subarachnoid hemorrhage. Small numbers of intracranial hemorrhage could be due to the lack of association with this subtype of stroke. Overall, stroke is associated more As with dietary factors.
food frequency questionnaires makes no distinction between regular and decaffeinated coffee, but decaffeinated coffee consumption in the Swedish population is low.
Larsson notes that the possible pathways by which coffee consumption may reduce the risk of stroke include weakness subclinical inflammation, oxidative stress reduction and improved insulin sensitivity.
"Some women have avoided drinking coffee because they felt they were healthy. In fact, there is growing evidence that moderate coffee consumption may reduce the risk of some diseases such as diabetes, liver cancer and possibly stroke, "concludes Larsson
