Decrease your blood pressure by adding one good tasting item to your normal meals
It’s important to keep the blood pressure low as we get older. High blood pressure especially
increases the risk for stroke.Postmenopausal women often develop hypertension and arterial stiffness. For that reason the
following research included postmenopausal women who had started to experience increased
blood pressure (Johnson SA, et.al., 2015).
Systolic and diastolic blood pressures were evaluated and arterial stiffness was assessed at the
start of the study and at the end. This was an 8-week, randomised double-blind
placebo-controlled trial. The participants received either 22 g of freeze-dried blueberry powder
or 22 g of control powder.
After 8 weeks, the systolic and diastolic blood pressure was significantly lower in the group
that took the blueberry powder, and arterial stiffness had also improved.
Nitric oxide levels improved significantly in the blueberry group whereas there were no changes
in Nitric oxide levels in the placebo group. Nitric oxide relaxes the muscles in the blood vessels
and improves blood circulation.
This may be the reason blueberries lowered the blood pressure.
Eating blueberries every day is a good idea. If it is difficult to find fresh ones, you can usually
find frozen blueberries.
