J gerontol Series A: blueberry or blood pressure reducing drug

February 22, 2019 / BIOON / - a new study published in Journal of Gerontology series a found that eating 200 grams of blueberries a day for one month can significantly improve the vascular function and systolic blood pressure of healthy people Photo source: https://stock.tuchong.com researchers from King's College London studied 40 healthy volunteers for a month The volunteers were randomly given 200 grams of blueberries or a matching control drink each day The researchers monitored chemicals in the blood and urine of volunteers, as well as flow mediated dilation (FMD) in their blood and brachial arteries, an indicator of how blood vessels dilate as blood flow increases, considered a sensitive biomarker of cardiovascular disease risk In a subsequent study, the researchers compared the effect of blueberry drinks with purified anthocyanins, a plant chemical that determines the blue, red, purple, and pink colors of some vegetables and fruits They also compared the effects of colored drinks containing the same amount of fiber, minerals or vitamins Their findings are as follows: after drinking blueberry beverage for two hours, we can observe its effect on blood vessel function, which can be maintained for one month even after fasting for one night; during this month, blood pressure dropped by 5 MmHg, which is similar to the research results of common antihypertensive drugs; drinks containing purified anthocyanin can also improve the function of endothelium, which is the barrier between blood or lymph and surrounding tissues, and plays a key role in coagulation and blood pressure regulation; whether it is a light drink or a drink containing the same fiber, mineral or vitamin, it is 2 hours after drinking And 6 hours had significant effect on FDM Dr ana Rodriguez mateos, from the Department of Nutrition Sciences, who led the study, said: "although it's the best way to eat the whole blueberry to get all the nutrients, our study found that anthocyanin may be the key to the benefits of blueberry If we can see that the effect of eating blueberries every day on vascular function can last a lifetime, then we can reduce the risk of cardiovascular disease by 20% " Reference materials: Ana Rodriguez mateos et al, circulating anticyanin metals mediate miscellaneous benefits of blueberry: insights from randomly controlled trials, metals, and genetics, the journals of Gerontology: Series A (2019) Doi: 10.1093/gerona/glz047
