Blueberries can help prevent hypertension
British and U.S. researchers collaborated to complete a large-scale study, eat more anthocyanin-rich blueberries to help prevent hypertension and its causes of various diseases.
Researchers at the University of East Anglia in the United Kingdom and their U.S. counterparts reported in a new issue of the American Journal of Clinical Nutrition that they followed the health of more than 100,000 volunteers for up to 14 years in order to study the effects of diet on blood pressure. During that time, these volunteers reported their health status every two years and their diet every four years. At the start of the program, all had no symptoms of high blood pressure, while 14 years later, about 35,000 people had symptoms of high blood pressure.
Researchers who analyzed the volunteers' diets found that people who regularly ate anthocyanin-rich blueberries and consequently consumed large amounts of anthocyanins had a 10 percent lower risk of developing high blood pressure compared with those who didn't eat much blueberries.
Addin Cassidy, a professor at the University of East Anglia who participated in the study, said the research confirmed the blood pressure-lowering effects of anthocyanins. Anthocyanins are flavonoids, which are also found in foods such as tea, fruit juice, red wine and dark chocolate. It has been known that flavonoids have the effect of lowering blood pressure, and this study shows that although people can from different ways to intake of flavonoids, but still rich in anthocyanins blueberries lowering blood pressure effect is the most significant, also rich in anthocyanins strawberries lowering blood pressure effect is also good.
Cassidy revealed that the researchers will conduct more precise quantitative studies to determine what the optimal intake of anthocyanins in the daily diet is.

It is because of the blueberry fruit is rich in nutrients, is high in amino acids, high zinc, high calcium, high iron, high copper, high vitamin nutrition and health care fruit. It not only has good nutritional health effects, but also has the prevention of cerebral nerve aging, strong heart, anti-cancer soften blood vessels, enhance the human organism immunity and other functions.
