Pistachios: Historic and Healthy Nuts

By: Habeeb Salloum/Arab America Contributing Writer

Pistachios (Pistacia vera), whose name derives from the Persian word pisteh, is believed to have originated in Iran.  For thousands of years they thrived in western Asia, in the area from Syria to Afghanistan.  They were prized for their creamy flavour and nutritious value by royalty and the elite in the ancient world, and were the favourite nuts in the imperial court of Queen Belghais of Sheba.  Interestingly, they are one of only two nuts that are mentioned in the Bible.

During Roman times the pistachio tree was introduced to Greece and Italy from Syria.  On the other hand some historians indicate that after the fall of the Roman Empire, the cultivation of pistachios disappeared from Italy and were later re-introduced by the Arabs to Sicily after their conquest of the island.  In his book Islamic Sicily, Aziz Ahmad states the name of the ‘pistachio’ possibly came into Sicilian from Arabic then moved on into the other languages of Europe.

Pistachios were introduced to the U.S.A. by a Syrian immigrant in the late 1890’s and began to be cultivated commercially in California.   Today, the state’s annual production is second only to that of Iran, the largest producer in the world, followed by Turkey and Syria, the third and fourth largest.  Other pistachio producing areas are the Indian sub-continent, China, Greece, Italy and Tunisia. However, the vast majority of the world supply of pistachios is consumed in the United States.

Also known as the green almond, the pistachio is related to the cashew.  The tree, growing at times up to 30-feet tall, thrives in stony-poor soil and in lands with cool winters.  It does well in high heat and with a bit of moisture, needing little care and living, at times, for centuries.  Its attractive foliage and clusters of reddish-wrinkled fruits makes it an eye-catching ornamental plant.

The nuts are harvested when the outer husk covering the shell loosens and falls off easily when the tree is shaken.  The husk covers a pale green nut encased in a beige coloured shell. A single tree in its prime can produce some 50 pounds of husked nuts.  When placed in airtight plastic bags and stored in a refrigerator un-roasted and roasted pistachios will last for months. However when frozen, they will last for years and still retain their flavour and mineral content.

Considered one of the best of the well-known nuts, in the majority of cases, pistachios are roasted and salted un-shelled.   From 80 to 90% of pistachios are prepared in this way and consumed as snacks. Un-roasted and shelled pistachios have a sweet flavour and are used in cooking.  In the Middle East they are mainly utilized in desserts both as ingredients and for decorative purposes.

Unsalted pistachio nuts are a very healthy food, but rich in oil which can add to weight problems.  They should be substituted for other high fat foods, but only a small handful, no more than four times a week. Unsalted, they have a high-potassium, low-sodium content, hence, helping in regulating the body’s fluid balance, especially aiding in normalizing blood pressure.  In addition, they are also an excellent source of protein and have a good amount of calcium, iron, phosphorus, thiamine, zinc, vitamin B6 and vitamin E.

Pistachios are cholesterol free and relatively low in calories in comparison to other nuts.  They are high in fibre and low in saturated fat but contain a good amount of monounsaturated fat, leading to a cut in the risk of heart attack.

Pistachios also contain an antioxidant that has been associated with a decreased risk for developing diseases such as cancer. Sarah K. Gebauer, a graduate student in integrative biosciences at Penn State University, said in April 2007 to attendees at the Experimental Biology Conference, “Pistachio amounts of 1.5 ounces and 3 ounces – one to two handfuls – reduced risk for cardiovascular disease by significantly reducing LDL cholesterol levels and the higher dose significantly reduced lipoprotein ratios.”

Much used in Middle Eastern, Mediterranean and Indian cuisines, unsalted pistachios, containing 165 calories per ounce are an excellent addition to vegetarian diets.  They are superb when used as ingredients in appetizers, breads, cookies, ice creams and other sweets, muffins, pâtés, pesto, salads, sauces, stuffing for fish and meats, vegetarian foods and, as well, for garnishing.

These kitchen uses and their healthful attributes are appreciated in many countries, especially in Syria where visitors are often given a bag of pistachios as a parting gift.  Perhaps, these few recipes will give an idea as to why pistachios make excellent gifts.
