Finland – Health benefits from lingonberry juice

In a study conducted at the University of Helsinki, the juice was found to lower the blood pressure of hypertensive lab rats. It was already known that by consuming berries that are rich in micronutrients known as polyphenols, people can reduce their risk of cardiovascular disease – lingonberries, blackcurrants and cranberries.

Researcher Anne Kivimäki recently set about feeding cold-pressed and diluted juice of all three of these berries – separately, not mixed together – to different groups of rats that had been genetically modified to have high blood pressure. After eight to 10 weeks of this diet (in which the juice replaced the animals’ water) it was noted that the higher the polyphenol levels of any of the juices, the better they were at improving the function of compromised blood vessels. The lingonberry juice alone, however, also excelled at preventing the expression of genes that are associated with low-grade inflammation of the aorta.

This resulted in the rats that consumed the lingonberry juice experiencing more of a drop in their blood pressure than those that drank the other juices. It is believed that also contributing to this drop may have been the lingonberry juice’s effect on the animals’ renin-angiotensin system, which regulates blood pressure. NewAtlas
