        • Disadvantages
          • Stroke
            • High blood pressure damages arteries in the brain
            • If the arteries burst, they cause a stroke
          • Heart disease
            • High blood pressure= heart working more
              • Over time can lead to heart failure or heart attacks
            • Damage to the arteries that feed the heart can cause heart attacks
          • High blood pressure
            • Salt makes the body retain water
            • Leads to high blood pressure
          • Kidney damage
            • Kidney filter excess salt from blood
            • Over time, too much salt can cause damage to the kidneys
