WOMEN WHO EAT BERRIES HAVE FEWER HEART ATTACKS

Saturday, April 19, 2014

18 year study of nearly 100,000 women provides encouraging information.

Eating three or more servings of blueberries and strawberries per week may help women reduce their risk of a heart attack by as much as one-third, according to a new study. Blueberries and strawberries contain high levels of naturally occurring compounds called dietary flavonoids, also found in grapes and wine, blackberries, eggplant, and other fruits and vegetables. A specific sub-class of flavonoids, called anthocyanins, may help dilate arteries, counter the buildup of plaque and provide other cardiovascular benefits, according to the study. 

“Blueberries and strawberries can easily be incorporated into what women eat every week,” said Eric Rimm, Associate Professor of Nutrition and Epidemiology at Harvard. “This simple dietary change could have a significant impact on prevention efforts.”

Blueberries and strawberries were part of this analysis simply because they are the most-eaten berries in the United States. But it’s possible that other foods could produce the same results, researchers said.

Scientists from the Harvard School of Public Health in the U. S. and the University of East Anglia in England conducted a study among 93,600 women ages 25 to 42. The women completed questionnaires about their diet every four years for 18 years. 

During the study, 405 heart attacks occurred. Women who ate the most blueberries and strawberries had a 32-percent reduction in their risk of heart attack compared to women who ate the berries once a month or less – even in women who otherwise ate a diet rich in other fruits and vegetables. 

The findings were independent of other risk factors, such as age, high blood pressure, family history of heart attack, body mass, exercise, smoking, caffeine or alcohol intake.
