Archaeologists have found evidence from excavations that pistachio nuts were a common food as early as 6750 BC. The Hanging Gardens of Babylon were said to have contained pistachio trees around 700 BC.

Today, studies have shown that 32-63 grams per day of pistachio nut can significantly elevate plasma levels of lutein, alpha-carotene, beta-carotene, and gamma-tocopherol. To learn more about pistachios, click here and click the video link above.
