Another great way to lower blood pressure is losing weight and going on a diet as this extra fat promotes stiffness of your arteries and build-up of atherosclerotic plaques that result in thrombosis and embolisms; so losing weight helps keep your arteries healthy and lowers the effort your heart has to go through to pump blood efficiently
One of the best effects of the DASH diet is that it helps you lose weight and improves your lipid profile through restricting unhealthy fat and salt consumption.
