Among the possible health benefits of pistachios:

• High levels of unsaturated fatty acids and potassium. Both have  antioxidant and anti-inflammatory traits.

• They can lower your chances for  cardiovascular disease. 

• Pistachios are bursting with the fiber, minerals, and unsaturated fat that can help keep your  blood sugar, blood pressure, and cholesterol in check.

• Their fiber and  protein can make you feel fuller for longer. This fiber can also have a positive effect on your gut by aiding "good" bacteria.

• They can help you manage your weight since they’re a nutritious and satisfying snack. This may help you eat less overall and lose weight. Buying pistachios in their shells slows down your eating.

• Some studies suggest that eating pistachios lowers the amount of fat and sugar (glycemic index) in your blood, as well as improves the flexibility and tone of your blood vessels.
