How does a permanent, 7-point drop in blood pressure sound?
And what if it only required a glass of delicious juice?
Great news: a new study has proven that one specific type of juice is more effective than most blood pressure medications in dropping your blood pressure.
And it comes without a trace of side effects.
Plus, you can buy it in all supermarkets.
Scientists from the University of Oslo and the Norwegian Institute of Food, Fisheries and Aquaculture Research have discovered that berry juice has a significant lowering effect on blood pressure.
In the study, researchers split 134 volunteers into three groups: a control group that drank non-berry juice (the control group), a group that drank polyphenol-rich berry juice, and a group that drank polyphenol-rich berry juice combined with polyphenol-rich blackberry juice to obtain a much higher polyphenol count.
Each group had to drink about 500 ml of the juice daily.
Their results, as published in the British Journal of Nutrition in October 2015, were as follows:
• After six weeks, the polyphenol juice drinkers had lost 6.9 more systolic points than the control group.
• After 12 weeks, the polyphenol juice drinkers had lost 3.4 systolic points more than the control group.
• While the polyphenol juice drinkers lost 6.4 points up to week six, they lost only 0.8 points between week six and week 12. There appears to be a limit to the power of this juice, after all.
• There was no difference between the polyphenol juice drinkers and the extra high polyphenol juice drinkers.
• Compared to the subjects with normal blood pressure, those with high blood pressure experienced a much greater drop: 7.3 points more than the control group after six weeks, and 6.8 points more than the control group after 12 weeks.
• At both the 6-week and the 12-week points, the scientists took three blood pressure measures, which showed that the variation between the three measures was smaller for the polyphenol juice drinkers than for the control group.
If you want to duplicate this effect at home, you should know that the juices that worked well were normal commercial brands that contained red grapes, cherries, chokeberries, or bilberries. If these are among your favorite juices, then you are in luck.
Since the juices also reduced blood pressure variations between the three measures when taken one minute apart, the authors concluded that polyphenols probably affect stress-related high blood pressure, rather than resting high blood pressure. This is good, because blood pressure spikes that are accompanied by stress often bring about the worst cardiovascular consequences, such as heart attacks and stroke.
One thing to keep in mind, however, is that berry juice is very high in natural sugar and calories. This can be a problem, especially if you are watching your blood sugar levels. Therefore, it may be better to eat the berries whole. This way, you are adding back in some beneficial fiber.
