"Epidemiological studies have shown that polyphenol-rich food reduces the risk of cardiovascular diseases. Lingonberry, bilberry, cranberry and blackcurrant are excellent sources of polyphenols," the university wrote in a press release.
Kivimäki found that diluted lingonberry juice significantly lowered high blood pressure, and juice that contained more polyphenols improved impaired blood vessel function to the level of healthy vessels.
The juice did not prevent the age-related elevation of blood pressure typical to the hypertensive animal strain, however.

“These experimental findings need evidence from comparative clinical studies on healthy individuals with slightly elevated blood pressure who, at this point, have been given nutritional and lifestyle guidance instead of drug therapy. Lingonberry juice is no substitute for medication, but it is a good dietary supplement,” Kivimäki says.
Lingonberry isn't nearly as common in the U.S. as cranberry, however, but you can order it online.
