Evidence from a large Adventist Health Study-2 cohort suggests that plant-based diets lower the risk of hypertension as compared to omnivorous diets (consumption of meat).  


What was the purpose of the study? 

Researchers studied 500 white subjects and assessed the impact of their dietary patterns on the risk of hypertension. 



What did they find? 

  • Vegan Adventists had lower systolic and diastolic blood pressures vs omnivorous adventists
  • Vegetarians (mainly vegans) were less likely to be using anti-hypertensive medications
  • Vegans had a 63% lower risk of hypertension vs omnivores
  • Lacto-ovo vegetarians had a 43% lower risk of hypertension vs omnivores
  • Partial vegetarians had a 8% lower risk of hypertension vs omnivores
  • Reduction in BMI seems to have a partial role in the positive effects of a vegetarian diet on the risk of hypertension




It appears from this study that the more plant-based one becomes, the less their risk of hypertension. This study only had white participants.
