For nutrition and diet info that is helpful look up DASH meal plan. It stands for dietary approaches to stop hypertension. As far as nutrition goes a natural and healthy diet includes less processed foods (less salt) and more potassium, magnesium, and calcium. If the hypertension does not respond adequately to diet and exercise then medication can be a lifesaver. A healthy diet as well as weight loss can really help lower or even help prevent high blood pressure.
