Cross-sectional epidemiological studies suggest that ovolactovegetarians have lower blood pressure and less of a rise in blood pressure with age than meat eaters. Controlled dietary intervention trials in normotensive and untreated mild hypertensive have provided more direct evidence for a direct dietary effect on blood pressure. Studies designed to identify the nutrients involved suggest that neither polyunsaturated fat, saturated fat, cholesterol, potassium, magnesium, sodium, or total protein intake are independently responsible. The pathophysiological mechanisms involved are also unclear. In view of the complex changes involved in changing to a vegetarian diet, research in this area needs to pay careful attention to experimental design. This is an area of research that has important implications for the control of hypertensive cardiovascular disease in the community by means other than drugs.
横断面流行病学研究表明，蛋奶素食者比肉食者血压更低，且随着年龄增长血压升高幅度更小。在血压正常和未经治疗的轻度高血压患者中进行的对照饮食干预试验，为饮食对血压的直接影响提供了更直接的证据。旨在确定相关营养素的研究表明，多不饱和脂肪、饱和脂肪、胆固醇、钾、镁、钠或总蛋白摄入量均非独立起作用。其中涉及的病理生理机制也尚不清楚。鉴于转向素食饮食涉及复杂变化，该领域研究需谨慎关注实验设计。这是一个对通过非药物手段控制社区高血压心血管疾病具有重要意义的研究领域。
