Voedsel
met veel vezels tegen hoge bloeddruk.*
Uit
analyse van meer dan 25 studies blijkt dat voeding rijk aan vezels ( 7 tot 19
grams per dag) de bloeddruk duidelijk kan verlagen. Meer vezels zitten in
groente, fruit en volkoren graanproducten..
Dietary
Fiber Fights High Blood Pressure
A
review of studies supports intake of fruits, grains and vegetables
--
A high-fiber
diet may help reduce high blood
pressure
and may even improve healthy blood pressure levels, a new study finds.
Researchers
at Tulane University analyzed data on almost 1,500 adults in more than two dozen
studies and found that eating between about 7 to 19 grams of fiber a day led to
a reduction in both systolic and diastolic blood pressure "We performed a
comprehensive analysis of data from 25 clinical trials and all the data pointed
to one strong conclusion -- adding fiber to a person's diet has a health effect
on their blood pressure," lead author and medical student Seamus Whelton
said in a prepared statement.
This
type of study, called a meta-analysis, combines data from a number of studies to
spot trends that otherwise might not be observed. "Analyzing a large number
of studies lends strength to the conclusions of clinical trials that involved
too few participants [individually] to show an effect of dietary
fiber
on blood pressure," Whelton explained.
He
and his colleagues recommend that people eat fruits and vegetables in order to
increase their intake of dietary fiber. Other changes in diet and exercise can
also help reduce blood pressure and people should discuss these with their
doctor, Whelton added. (Maart 2005)
