High blood pressure, or hypertension, is a risk factor for cardiovascular disease, stroke, and kidney disease. With around 15–20% of our blood going to the brain, the National Institute of Aging part of the National Institutes of Health, explain that “the blood flow that keeps the brain healthy can, if reduced or blocked, harm this essential organ.”
The study, published in Diabetes and Metabolism, examined 159 healthy volunteers split into two groups. Both groups maintained their regular diet, with one key difference: One group purchased their foods from local growers who did not use additives in processing, while others purchased items found at traditional grocery stores. Both groups followed essentially a Mediterranean diet, which many researchers regard as one of the healthiest diets.
In a 2013 study, people with hypertension were found to have a significant reduction in blood pressure after consuming five ounces (150ml) of pomegranate juice daily for two weeks.
