Cranberries provide a wide variety of benefits including antioxidants for protection against high blood pressure, high cholesterol, as well as lots of vitamin C and other antioxidant properties that are beneficial in the fight against heart disease and stroke. Cranberries may lower blood pressure levels in those with Chronic Kidney Disease. A study also revealed that drinking cranberry juice had an average decrease in systolic (measure of arterial pressure during heart contractions) and diastolic (measure of arterial pressure between contractions) blood pressure of 3 mm Hg each. Researchers pointed out that this 3 mm Hg drop in both systolic and diastolic blood pressure is significant since most non-medicinal blood pressure lowering strategies often result in a decrease in systolic blood pressure, but not diastolic.
