Blueberry Bonus

Wednesday, April 29, 2015

Blueberries may help lower blood pressure and make arteries more flexible.

Researchers randomly assigned 48 post-menopausal women with prehypertension or hypertension (high blood pressure) to eat a daily dose of freeze-dried blueberry powder or a fake blueberry powder made of sugar, maltodextrin, and artificial colors and flavors. The dose of freeze-dried blueberry powder (22 grams) was equivalent to one cup of fresh blueberries.

After two months, systolic blood pressure dropped by an impressive 7 points and diastolic pressure fell by 5 points in the freeze-dried-blueberry eaters, but neither budged in those who got the imitation blueberry. What's more, the arteries of the blueberry eaters---but not the fake-blueberry eaters---were less stiff than they were when the people entered the study.
