Most pistachios are grown in California and marketed with their natural tan shells. They're a good source of protein and fiber.
An ounce of pistachios contains 160 calories and, like all nuts, they're relatively high in mono-unsaturated fat, which has been shown to lower blood cholesterol. Because nuts are low in saturated fat and contain no choles-terol, they no longer have an unhealthy reputation.Just an ounce of pistachios contains a whopping 3.1 grams of fiber, too.
They're excellent keepers when stored properly. To keep them at their freshest, store pistachios in a refrigerated airtight container or keep them in the freezer for long-term storage.
To restore pistachios that have lost their crispness, toast the nutmeats at 200 degrees for 10-15 minutes.
California pistachios are available year-round.
