Drinking lingonberry juice could have long term positive benefits on health by lowering bloody pressure and improving vascular functions.

That’s the findings of research by Anne Kivimäki from the University of Helsinki who discovered that foods high in a substance called polyphenols can reduce the risk of cardiovascular disease.

Excellent sources of polyphenols are found in the wild in Finland, and include lingonberries, bilberries, cranberries and blackcurrants.

“Based on these experimental studies, comparative clinical trials may be conducted in healthy subjects with mild hypertension [high blood pressure] for whom nutrition and lifestyle guidelines, but not yet medication, are recommended” explains Doctoral Researcher Kivimäki.

“Lingonberry nuice is not a substitute for medical treatment but it is a good nutritional supplement” she adds.

In her studies Anne Kivimäki investigated the effects of cold-pressed lingonberry, cranberry and blackcurrant juice in rats, some of which had genetically high blood pressure.

The rates were given juices for 8 to 10 weeks and Kivimäki found that diluted lingonberry juice significantly reduced already elevated blood pressure.

The study also revealed that lingonberry juice also blocked the expression of genes associated with low-grade inflammation of the arteries, while other types of berries did not show the same clear results.
