A study published in the the American Heart Associations’s journal Circulation, has revealed that women who consume at least three servings per week of blueberries or strawberries per week have a 30% reduced risk of a heart attack. While it is not new news that berries are good for us, it is good to hear it confirmed (especially at the cost of berries). I like this research for two reasons. One, the subjects were young women (in many studies the subjects were men) and two, the researchers “controlled” for variables such as weight, exercise, family history, blood pressure, caffeine and alcohol intake.
It is believed that the active ingredient in the berries is anthocyanin, the researchers caution that it is not possible to know for sure which of the many components of a blueberry is the one responsible for the good effects. It could be another component, or all of them. So eat whole foods, not dietary supplements !
Other good news: research has indicated that the nutrients in blueberries are fairly well preserved in the freezing process.
