Everybody’s talking about cholesterol. Well, pistachios can help support cardiovascular management thanks to something called phytosterols (a plant sterol found abundantly in pistachios) which actually compete with cholesterol from the diet for absorption.  Due to their nutritional composition or phytonutrients package, pistachios may be unique from other nuts in their ability to elevate healthy HDL cholesterol levels, when eaten as part of a diet low in saturated fat.
