The pistachio has a delicious flavor and a high nutritious value, high in monounsaturated fat, fiber, thiamin and vitamin B6, and minerals such as phosphorus, potassium, copper, and manganese. They are also a protein source, riboflavin, vitamins A, E, and K, and other minerals such as iron, magnesium, zinc, and selenium.

Pistachios have glucose- and insulin-lowering effects, so they may help you lower blood sugar levels. Eating pistachios every day may also improve some cardiometabolic risk factors in adults with well-controlled type 2 diabetes.

A scientific study also observed that a daily intake of pistachios of 44 g might help improve nutrient intake without affecting body weight or body composition.
