Vis tegen beroertes.
Uit analyses van verschillende grote studies blijkt dat de
kans op een beroerte, als gevolg van een afsluiting van een bloedvat,
aanzienlijk minder wordt door het wekelijks eten van vis.
More evidence that fish
consumption reduces the chances of having a stroke comes from an analysis of
results from several large studies.
In fact, the findings suggest
that "the incidence of ischemic stroke might be significantly reduced by
consuming fish as seldom as 1 to 3 times per month," Dr. Ka He, at
Northwestern University in Chicago, and associates comment in their report in
the medical journal Stroke.
Ischemic stroke refers to a
blockage of blood supply to the brain, as opposed to hemorrhagic stroke, which
is caused by bleeding in the brain.
The team's search of the
medical literature on the topic of risk factors for stroke turned up eight
independent studies published since published since 1966. All told, there were
more than 200,000 study participants aged 34 to 103 years, who were followed
for anywhere from 4 years to 30 years.
Most studies were conducted in
the U.S.; one was from Europe, one from China and one from Japan.
The risk of stroke was 13
percent lower among those who ate fish at least once weekly compared with
those who did so less than once per month, and the results were consistent
across most studies.
However, the benefit was
limited largely to reduced risk of ischemic stroke. The three large studies
that included data regarding different types of stroke showed no less risk for
hemorrhagic stroke with increasing fish intake.
Dr. He's group cautions that
these findings should not be presumed to mean that fish oil supplements would
provide the same benefit. They say the possibility that other, unknown
components of fish should get the credit "cannot be ruled out."
