They are also an excellent source of protein and fibre. A single once (28g) of roasted pistachio nuts deliver 13% of the recommended daily intake of protein and 12% of the recommended daily amount of fibre. And you get an amazing 47 nuts in one ounce!
Two recent studies show that including pistachios regularly in your diet significantly reduces LDL cholesterol and increase HDL cholesterol.
They also contain a compound, oleanolic acid, with anti-inflammatory effects.
Pistachios protect the liver from the damaging effects of three liver enzymes - alkaline phosphatase, alanine aminotreansferase and aspartate aminotransferase - along with reducing bilirubin levels. (Bilirubin is a yellowish pigment in bile whose accumulation is a primary symptom of jaundice.)

Like other types of nuts, pistachios provide valuable amounts of minerals including calcium, iron, magnesium and zinc.
They are the richest source of potassium of all nuts - just 1 ounce/28 grams deliver as much potassium as an orange and 2 ounces/56 grams provide more potassium than a medium-size banana. Both magnesium and potassium are protective against heart disease.
