2009 AHS-2 Report: Vegans have Lower Blood Pressure
I was reading the latest issue of the Vegetarian Nutrition Dietetic Practice Group’s newsletter and saw that there had been a review article published in 2009 that listed data from the Adventist Health Study-2 that has not been reported elsewhere to my knowledge. It is cross-sectional data that showed vegans to have a 75% reduced risk of high blood pressure compared to non-vegetarians.
More details can be seen in Table 11 of Disease Markers of Vegetarians.
Because this is cross-sectional data, it does not mean a vegan diet reduces the risk of high blood pressure by 75%. It could be that people with high blood pressure are less likely to become vegan. And the results were not adjusted for smoking.
Prospective data from AHS-2 should help clarify how much is from the vegan diet in the coming years.
