Stirring a few blueberries or strawberries into your Greek yogurt three times a week could lower your risk of a heart attack by about a third, finds a new study from the Hartford School of Public Health. To put that in perspective: For safeguarding your heart, eating berries is as effective as becoming a vegetarian.
Researchers who tracked the diets of 93,600 women found that those who ate more than three servings of strawberries and blueberries per week were 32% less likely to have a heart attack during the 18-year study–even those with a history of high blood pressure. The source of berry power; anthocyanins, flavonoids that give the fruit their bright colors. “They seem to make arteries and blood vessels more flexible, which lowers blood pressure, ” says study coauthor Eric Rimm,ScD. Aim for three 1/2-cup servings of fresh or frozen berries weekly.
