Effect and function of blueberry - prevention of hypertension

A large-scale study by British and American researchers shows that eating blueberries rich in anthocyanins can help prevent high blood pressure and various diseases caused by it.

Researchers from the University of East Anglia and their counterparts in the United States reported in the new issue of the American Journal of clinical nutrition that in order to study the impact of diet on blood pressure, they conducted a 14 year follow-up survey on the health status of more than 100000 volunteers. Meanwhile, the volunteers reported their health every two years and their diet every four years. At the start of the project, no one had symptoms of high blood pressure, compared with about 35000 14 years later.

After analyzing the dietary status of volunteers, the researchers found that those who regularly ate blueberries rich in anthocyanins and therefore consumed a large amount of anthocyanins had a 10% lower risk of high blood pressure than those who did not eat blueberries much

Edin Middleton Cassidy, a professor at the University of East Anglia who participated in the study, said the study confirmed the effect of anthocyanins on blood pressure. Anthocyanins are flavonoids, which are also found in tea, fruit juice, red wine, dark chocolate and other foods. It has been known that flavonoids have the effect of lowering blood pressure. This study shows that although people can take flavonoids from different ways, blueberries rich in anthocyanins have the most significant effect on lowering blood pressure. Strawberry rich in anthocyanins also has a good effect on lowering blood pressure.

Cassidy revealed that next researchers will carry out more precise quantitative research to determine the optimal consumption of anthocyanins in the daily diet.

Unlike other antioxidants, anthocyanins can directly protect the brain and nervous system through the blood-brain barrier.
