>If you want to keep your blood pressure normal, weight reduction and exercise help, but did you know it is not just reducing your sodium that is helpful.
You should also increase the potassium and calcium in your diet to keep hypertension at bay. There are many studies that have found that people who stay healthy through calcium and potassium rich foods have decreased their numbers in blood pressure. What a normal blood pressure has also changed. Now doctors want you to have a reading of 110/70 instead of 120/80, and if you have hypertension which is 140/90 or above, you need to get your blood pressure under control, so try some foods rich in potassium and calcium, and get some exercise!
And if you have hypertension, there are lifestyle modifications  such as weight reduction, a DASH eating plan: Dietary Approaches to Stop Hypertension which is rich in fruits and vegetables and low in fat.
