Pistachios Help Stress

Pistachio nuts may improve stress response and blood pressure in diabetics.

Penn State researchers randomized two groups of type-2 diabetics to different diets. All consumed a heart healthy diet, but the experimental group's diet included 2 daily servings of pistachios.  Researchers provided all the meals for 4 weeks. The blood vessels of those eating the pistachios remained more relaxed and open during a cold water challenge and stressful mental test. They also found real world measures of blood pressure were lower.

Positive Tip: Unsalted pistachios in moderation may be a good addition to a healthy diet.
