Whole grains positively impact a number of places which indirectly may induce the lowering of blood pressure. They aid in the control of one’s weight, decrease insulin resistance and increase one’s consumption of potassium. And all of the above factors link (be it after a stage or so) to the lowering blood pressure. Other than this, gram flour specifically prevents high blood pressure as it contains low levels of sodium. While cardamom reduces stress that in turn improves blood circulation. And barley contains high levels of potassium which help in the improvement of blood pressure.
