Saturday May 24, 2014 (foodconsumer.org) -- A study recently published in JAMA Internal Medicine suggests following a vegetarian diet can prevent high blood pressure, which has been known to increase risk of cardiovascular disease.

The study led by Yoko Yokoyama, PhD, MPH affiliated with the National Cerebral and Cardiovascular Center in Osaka, Japan and colleagues shows people eating a vegetarian diet had significantly lower both systolic blood pressure and diastolic blood pressure, compared with those eating an omnivorous diet.

Specifically an analysis of data from seven controlled trials shows men and women who ate a vegetarian diet reduced their systolic blood pressure by 4.8 mm Hg and diastolic blood pressure by 2.2 mm Hg, compared with individuals eating omnivorous diets.

An meta-analysis of data from 32 observational studies revealed men and women eating a vegetarian diet lowered their systolic blood by 6.9 mm Hg and diastolic blood pressure by 4.7 mm Hg, compared with those eating omnivorous diets.

All the studies were published prior to October, 2013 and all participants were at least 20 years old. A total of 311 participants in seven trials were at a mean age of 44.5 years. A total of 21,604 participants in 32 observational studies were at the mean age of 46.6 years.

The study concluded that eating a vegetarian diet can prevent high blood pressure. (David Liu, PHD)
