You can lower your systolic blood pressure (the top number) by switching to the DASH diet. The DASH diet is based on 2,000 calories a day. It's rich in fruits, vegetables, and low-fat dairy products. It's also low in saturated fat, cholesterol, and total fat. According to studies, adopting a DASH diet can reduce systolic blood pressure by eight to 14 points. For healthy adults 65 and older with an average systolic 130, the goal is to get it lowered. In general, the target for your blood pressure should be around 120/80.
