Ideal blood pressure for both genders is anything below a reading of 120/80, according to WebMD. A systolic reading between 120 and 139, and a diastolic reading of 80 to 89, is defined as prehypertension. Hypertension, or high blood pressure, is above 140/90, or 150/90 for people over age 60.
The best way for men to maintain a healthy blood pressure is to have a healthy diet. The National Institutes of Health conducted studies, as reported by WebMD, that showed the effectiveness of the Dietary Approaches to Stop Hypertension, or DASH, diet on preventing and lowering blood pressure. The DASH diet emphasizes plenty of fruits and vegetables and low-fat or non-fat dairy products. It also helps to reduce salt intake, because salt also increases blood pressure. The National High Blood Pressure Education Program recommends no more than 2,300 milligrams of salt a day.
