High Blood Pressure? Blueberry Help Pressure Release

According to the "Elsevier Health Sciences' report, any intervention can lower blood pressure has the potential to save lives. Sarah Johnson from Florida State University and her colleagues tested 48 menopausal women with essential hypertension who took 22 grams of frozen blueberry powder or 22 grams of placebo per person per day for 8 weeks. They published study results in the "Journal of Nutrition and Dietetics Association", showing that continuous daily consumption of blueberries for 8 weeks can significantly improve systolic and diastolic pressure. 

Blueberry is one of the richest sources of phenolic compounds, including flavonoids, phenolic acids and stilbenes, and is known for their abundant biological activity and high antioxidant capacity. In the end of the study period, experimenters taking the average of the blueberries, their average systolic blood pressure reduced by 5.1%, and average diastolic blood pressure reduced by 6.3%, while the control group taking the placebo had no corresponding decrease. In addition, nitric oxide, which is involved in endothelium vasodilation, increased significantly in the blueberry group from 9.11 to 15.35 micromole but there were no changes in the control group. The authors of the study, said: "Daily consumption of blueberries may lower blood pressure and arteriosclerosis, which may be in part, caused by increased production of nitric oxide."
