Blueberry lowers blood pressure
By David Liu, PHD
Tuesday Oct 16, 2012 (foodconsumer.org) -- Those who eat a high fat/high cholesterol diet may consider incorporating some blueberries in their diet as a new study in British Journal of Nutrition suggests that eating blueberries may offset some effect of the high fat high cholesterol diet.
A. Rodriguez-Mateos A at Department of Food and Nutritional Sciences, University of Reading in Reading, UK and colleagues conducted the study and found eating blueberries can lower blood pressure and improve endothelial function.
Intake of flavonoid containing foods has been already associated with lower risk of cardiovascular disease, according to previous studies.
The current study was intended to reveal how eating blueberries might affect blood pressure. For the study, rats fed a high fat/high cholesterol diet with or without a blueberry supplement were given for 10 weeks.
Rats on a high fat high cholesterol diet supplemented with blueberries significantly reduced their systolic blood pressure by 11 and 14 %, at weeks 8 and 10, respectively, compared with those fed on the a high fat high cholesterol diet only.
The researchers concluded "These data suggest that BB (blueberry)consumption can lower BP (blood pressure) and improve endothelial dysfunction induced by a high fat, high cholesterol containing diet."
