Pistachio nuts are one of the oldest ..

Pistachio nuts are one of the oldest known edible nuts, dating back at least 9,000 years.
The pistachio stands apart from other tree nuts due to its green color and the semi-opening shell. Like other tree nuts, however, pistachios contain a significant amount of fat.
The human body needs dietary fat to support normal body functions. Pistachio nuts contain very little saturated fat. Pistachio nuts contain no trans fat which is a fat considered of the worst type. Pistachio nuts serve as a good source of these "healthy" fats.
Pistachio nuts are both delicious and nutritious. They make a good snack.
Remember to eat these nuts in moderate amounts from time to time. Although pistachios are high in fat, most of the fat is the heart-healthy unsaturated fat, not saturated fat.
Pistachio nuts offer antioxidants and 18 vitamins and minerals, making them a healthy addition to any diet. So one could eat pistachio nuts as a snack, use them in salads, mix them or add them to baked items.
