Lingonberries are a Scandinavian berry that is similar in taste and appearance to the cranberries native to North America. Finnish scientists have found that lingonberries, but not cranberries or lingonberries, or blackcurrants, may help lower blood pressure.
I have previously written about lingonberries for cancer nutrition.
A team of scientists led by Dr. Anne Kivimaki from the Institute of Biomedicine at the University of Helsinki found that hypertensive lab rats given lingonberries developed normal blood pressure. All of the berries tested contain antioxidant procyanidins, flavonols, and flavon-3-ols, but lingonberry juice contain about 200% more than the other juices. The difference in antioxidant content, which also depends on how the berries are harvested and turned into juice, seems to make the difference in treating blood pressure.
Where can you find lingonberry juice to give it a try? Most Whole Foods stores and IKEA stores carry it. Try it instead of orange juice for a month and see if blood pressure goes down.
