One large glass of wine a day prevents common type of stroke.
To such conclusion researchers from the Karolinska Institutet in Sweden and University of Cambridge in the UK.
Monitoring the health of 20,000 people showed that three servings of alcohol a day may reduce the risk of ischemic stroke in which there is violation of cerebral circulation due to the formation of a blood clot in a blood vessel. 85% of strokes, according to statistics, are ischemic. When exceeding a given dose of alcohol, in contrast, leads to an increased risk of all types of strokes.
Moderate alcohol consumption (no more than a half of alcohol a day or a small glass of wine) reduced the risk of ischemic stroke by 10%. The same was true for those who consumed two times more alcohol, that is one big glass of wine. But a further increase in the amount of alcohol brought people to strokes. However, even moderate consumption of alcohol did not give any additional protection from hemorrhagic stroke – less common type in which there is bleeding in the brain.
The study authors emphasize that moderate alcohol consumption is associated with increased high density lipoproteins, increase insulin sensitivity and decreasing levels of fibrinogen (a protein that promotes blood clot formation), and inflammatory markers. But alcohol simultaneously increases blood pressure, and it is the single most important risk factor of stroke.
That is why scientists don’t actively go easy on the alcohol – hypertension outweighs all the pros of moderate drinking.
