Blueberries May Improve Cardiovascular Health


Blueberries may improve cardiovascular health, a new two-part study suggests. The phytochemicals found in blueberries can significantly reduce risk of cardiovascular.

There are no visible symptoms, hypertension affects nearly 1 in 3 adults in the United States. The condition puts pressure on the cardiovascular system, which could raise the risk of stroke, kidney failure, and heart failure.

A new research found that anthocyanins that gives blueberries their blue color can benefit the cardiovascular system. Ana Rodriguez-Mateos, Ph.D., from the Department of Nutritional Sciences at King’s College London, is the lead author of this new study. The results of thier findings now features in The Journals of Gerontology: Series A.

For the study, the team included 40 healthy participants and divided them into two groups. First group was instructed to drink 200 grams (g) of blueberries daily while the second group received a control drink.

The researchers then measured the flow-mediated dilation (FMD) of these volunteer’s brachial arteries by assessing tehir blood pressure. They wanted to see the effects of the blueberries. The specialists observed the effects of the blueberry drinks on the participants.

“Purified anthocyanins exerted a dose-dependent improvement of endothelial function in healthy humans, as measured by FMD,” report the authors.

Ana Rodriguez-Mateos explains, “If the changes we saw in blood vessel function after eating blueberries every day could be sustained for a person’s whole life, it could reduce their risk of developing cardiovascular disease by up to 20 percent.”
