One reason you could have high blood pressure is due to a diet that is lacking in fruits and vegetables and high in sodium. Sodium is a mineral that is necessary for optimal muscle contraction and heart functioning. Many adults typically meet the daily salt requirements, but sodium tends to be consumed in large excess. As a result, this places an increased load on the heart and it can increase your risk for hypertension. If your diet contains high amounts of sodium then it is wise to make a lifestyle adjustment or consult with your doctor. The typical adult needs about 2,400 mg of sodium and this amount can quickly add up throughout the day.
