High protein consumption may increase blood pressure, according to a new study published in The Journal of the American College of Nutrition. Researchers evaluated the diets of 121 patients with type 2 diabetes. Participants were divided into two groups according to blood pressure – uncontrolled (≥ 135/85 mm Hg) or controlled (≤ 135/85 mm Hg). According to a three-day diet analysis, the group with uncontrolled blood pressure consumed more protein and meat than the group with controlled blood pressure. The controlled blood pressure group also consumed a diet higher in carbohydrates. These findings follow previous studies that show the benefits of plant-based diets on blood pressure.
