Higher intake of vegetable protein associated with lower blood pressure levelsPeople who eat more protein from vegetables tend to have lower blood pressure, according to a new study in the January 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.Most adults have either high blood pressure (hypertension) or prehypertensive blood pressure levels, according to background information in the article. Previous studies have found evidence that meat eaters generally have higher blood pressure than vegetarians. Other research looked directly at the effect of high overall protein intake and found that people with higher total protein intake are likely to have lower blood pressure, the authors report.
