Pistachios Improve Cardiovascular Health Among Type 2 Diabetics

Pistachios are rich in fiber, potassium and antioxidants, and they are high in fat, but they are healthful fats, and may help type 2 diabetics keep their blood pressure under control, according to a study by Penn State researchers. The study compared isocaloric diets, one of which included 150 pistachios a day. Participants alternated between the diets, and measurements of stress responses were taken. With the pistachio diet, blood vessels remained more relaxed and open during the stress tests. Measures of blood pressure were significantly lower after the pistachio diet. Average sleep blood pressure was reduced by about four points, lowering workload on the heart.
