Twenty-nine patients who had suffered from essential hypertension for an average of 8 years, all receiving long-term medication for hypertension, were subject to therapy with vegan food for 1 year. In almost all cases medication was withdrawn or drastically reduced. There was a significant decrease in systolic and diastolic blood pressure. A number of reported symptoms disappeared. There was a significant improvement in a number of clinical variables as well as a significant change in various biochemical indices such as urea, haptoglobin, cholesterol and triglyceride concentrations in blood. Subjectively all patients reported improvement. Selected patients, with a fear of side-effects of medication, who are interested in alternative health care might replace conventional medication with this dietary regimen.
