Berries Boost Heart Health

Blueberries and strawberries contain high levels of naturally occurring compounds called dietary flavonoids – and, specifically the subclass of anthocyanins, which may help dilate arteries, counter the buildup of plaque, and provide other cardiovascular benefits.  Eric Rimm, from Harvard School of Public Health (Massachusetts, USA), and colleagues analyzed data collected among g93,600 women, ages 25 to 42 years, enrolled in the Nurses’ Health Study II. 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% 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 study authors conclude that: “A high intake of anthocyanins may reduce [heart attack] risk in predominantly young women.”
