(Ivanhoe Newswire) -- Grabbing a candy bar for dessert may be
better for you than you think. Foods rich in cocoa seem to reduce blood
pressure, according to an analysis of previously published research.
Foods rich in compounds like polyphenols are thought have
beneficial effects on blood pressure and cardiovascular risk. This compound can
be found in fruits and vegetables, which are both listed in the current
guidelines for people with hypertension, or high blood pressure. However, the
majority of total polyphenol intake in Western countries comes from tea and
cocoa products, which are not listed on current dietary guidelines for reducing
high blood pressure.
In a recent analysis of 10 previously published trials,
researchers found participants who consumed cocoa saw a 4.7-millimeter-reduction
of mercury in systolic blood pressure and roughly 2.8-millimeter- reduction in
diastolic blood pressure. Researchers report the effects are comparable to those
attained with blood pressure-lowering medications. The study reveals these types
of results could substantially reduce the risk of stroke by about 20 percent,
coronary heart disease by about 10 percent and all-cause mortality by about 8
percent.
Researchers gave another group of study participants tea
instead of cocoa but did not find any direct connection between drinking tea and
lower blood pressure. These results may have occurred because cocoa contains
more procyanids, another type of polyphenol, which may be more effective with
respect to their blood pressure-lowering potential.
Although the findings may have you reaching for a Snickers
bar, researchers stress this analysis does not indicate a widespread
recommendation for higher cocoa intake to decrease blood pressure. However, the
study does show it's reasonable to substitute phenol-rich cocoa products, such
as dark chocolate, for other high-calorie or high-fat desserts, or dairy
products.
