The ONE organ responsible for high blood pressure.
THE POWER OF BLUEBERRIES: FRUIT FOR LOWER BLOOD PRESSURE

Afterward, the researchers found that flow-mediated dilation improved by about 2% within two hours of consuming the blueberry drink and the effect was sustained after one month of daily consumption. Also, systolic blood pressure fell by an average of 5 millimeters of mercury.
Potentially reduces blood pressure
“Eating blueberries helps reduce blood pressure in people who have metabolic syndrome because it helps the body produce more nitric oxide, which relaxes your blood vessels,” Zumpano notes.
Study Shows Blueberries Can Reduce Hypertension
It is long known that blueberries are full of healthy antioxidants. However, a new study has revealed that the phytochemicals that give blueberries their beautiful blue color, known as anthocyanins, can also decrease one’s cardiovascular risk by 20 percent. The two-part study focused on 40 individuals with normal blood pressure levels and “perfect health.” To correctly test the power of blueberries, they split the group into two. One half was given a drink with 200 grams of blueberries, while the other half received a control drink. Researchers tracked the participants’ blood pressure over time and noticed a significant drop in blood pressure for the group consuming a daily dose of blueberries. For the second part of the study, researchers focused on confirming their hypothesis, which credited the anthocyanins in the blueberries for causing the drop in blood pressure. To do so, they gave one group of participants a beverage containing pure anthocyanins, while the other group was given a mix of vitamins and minerals to mimic those in blueberries without the addition of anthocyanins. The results of the study were overwhelmingly positive. The group that consumed 200 grams of blueberries a day for 40 days saw their blood pressure drop by five millimeters. However, the researchers saw results far before 40 days. Only two hours after consuming the blueberries, the researchers could see positive health benefits in the patients.
