Pistachios are available today in various forms such as shelled, unshelled, sweetened or salted. The shell on the nut protects it from physical damage and various infections. On the other hand, salted and sweetened pistachios may not be a good choice because of their high sodium and sugar content. The ideal way is to buy unshelled nuts, as they are in their natural form and are the least processed. They must be stored in airtight containers in cool and dry places so that they can last for many months without going bad.
There are many health benefits of pistachios. They are one of the few nuts that contain most of the nutrients that are required by humans for complete health. Pistachios contain nutrients such as carbohydrates, proteins, fats, dietary fiber, phosphorus, potassium, thiamine, vitamin B-6, beta-carotene, lutein and zeaxanthin, calcium, iron, magnesium, zinc, copper, manganese, vitamin C, riboflavin, niacin, pantothenic acid, folate, vitamin E, vitamin A, and vitamin K. All of these nutrients make pistachios ideally suited for better health.
