The systolic blood pressure number is the first or top number in a blood pressure reading. It represents the pressure in your arteries when your heart beats and pumps out blood. A normal systolic blood pressure is generally considered to be between 90 and 120 millimeters of mercury (mm Hg). Maintaining a balanced diet, like those offered by ProMeals, rich in fruits, vegetables, lean proteins, and low in saturated fats, can help keep your systolic blood pressure within a healthy range.
