Blueberries May Help Lower Blood Pressure, New Study Shows

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

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

Researchers randomly assigned 48 postmenopausal 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 (22grams) 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.

What to do: Eat more blueberries. This study doesn’t prove that the fruit will lower blood pressure and make arteries less stiff. It’s possible that another fruit might be equally effective, that freeze-dried blueberries work better than fresh blueberries, or that the impact of blueberries would wane over time.

But with such a flavor-rich, fiber-rich, vitamin-rich, low-calorie fruit, what have you got to lose?

  1. Good news>>>>>>>>however I have kidney stone formation problems and blueberries have a lot of oxalate and thus increase my risk of kidney stones. How does the freeze dried product compare in oxalate with the fresh blueberies?
