'Glutamic Acid, the Main Dietary Amino Acid, and Blood Pressure - The INTERMAP Study (International Collaborative Study of Macronutrients, Micronutrients and Blood Pressure), Circulation - Journal of the American Heart Association, July 2009
Study Design:
4680 men and women 40 to 59 years of age from 17 random population samples in Japan, China, the United Kingdom and the United States were surveyed.
Study Results:
Glutamic acid, which is present in vegetable protein, can help to lower blood pressure. The study found that the more dietary glutamic acid that the subjects consumed, the more their blood pressure fell.
