Here are a few fun facts for National Pistachio Day: Pistachio trees are among the oldest flowering nut trees. Scientists think humans may have eaten pistachios for as many as 9,000 years. Growing pistachios requires patience, as it takes seven to ten years for a pistachio tree to mature. In the Middle East they’re known as “smiling nuts” and the Chinese call them “happy nuts,” possibly because when they ripen, the shells crack open like little smiles. The shells themselves might slow down consumption, partly because it takes time to open them, and partly because the empty shells serve as a reminder of how many nuts have been eaten. Studies suggest in-shell pistachio snackers consume 41% fewer calories, an effect known as the “pistachio principle.” These little green nuts are a good source of protein, fiber, magnesium, thiamine, and phosphorus. They're also an excellent source of vitamin B6, copper, and manganese. Happy cracking!
