What Are Pistachios Good For?

Low in calories

Pistachios are one of the lowest calorie nuts, which means people can enjoy the health benefits of nuts while more easily staying within their daily calorie limits.One ounce of macadamia nuts, for example, contains 204 calories, while 1 ounce of pecans provides 196 calories. The same 1 ounce of pistachios contains just 159 calories.In one small study involving 28 participants with high cholesterol who ate 1 or 2 daily servings of pistachios over 4 weeks, researchers showed that they experienced an increase in their levels of the antioxidants lutein, α-carotene, and β-carotene compared to those who ate none.
