To prevent high blood pressure, everyone should be encouraged to make lifestyle modifications, such as eating a healthier diet, quitting smoking, and getting more exercise. Treatment with medication is recommended to lower blood pressure to less than 140/90 in people younger than 60, and less than 150/90 in people older than 60.
Eating a healthy diet, including the DASH diet (eating more fruits, vegetables, and low fat dairy products, less saturated and total fat).
Reducing the amount of sodium in your diet to less than 1,500 milligrams a day if you have high blood pressure. Healthy adults should try to limit their sodium intake to no more 2,300 milligrams a day (about 1 teaspoon of salt).
Getting regular aerobic exercise (such as brisk walking at least 30 minutes a day, several days a week).
Limiting alcohol to two drinks a day for men, one drink a day for women.
