Pistachios are small, green nuts that grow on the Pistacia vera tree, native to the Middle East and Central Asia. They are encased in a hard shell that splits open when the nut is ripe, making them easy to eat. These nuts are often enjoyed as a snack, either roasted and salted or raw, and are also used in various dishes and desserts. Rich in nutrients, pistachios are a good source of protein, healthy fats, and fiber. They contain vitamins such as Vitamin B6 and minerals like potassium and magnesium. Regular consumption of pistachios may support heart health and weight management due to their nutrient density.
