A systematic literature review published December 2016 in the Journal for Nurse Practitioners showed that hypertension – one of the most costly and over-medicated treatment regimes in the US – may be helped significantly with prescription of a vegetarian diet. Although there are numerous drug remedies, little is done as prevention. Vegetarian diets can be an adjunct or alternative to pharmacological therapies, along with exercise, and can be useful for sub-clinical patients who do not intend to take medication to treat high blood pressure. Lifestyle changes play a significant role in treatment of high blood pressure. Healthcare providers would do well to ask wellness care questions pertaining to smoking cessation, exercise, and diet when patients list hypertension as a symptom.
