Pistachios

Nutrition Notes

Relative to other nuts, pistachios have the fewest calories per ounce.  They're also rich in heart healthy monounsaturated fat (54% of their fat) and deliver potassium, calcium and magnesium. 

Long regarded for their culinary use, pistachios are also known for their ability to help fight heart disease.  Numerous studies have shown pistachios help lower LDL (bad) cholesterol. 

If you're watching your sodium intake, opt for unsalted roasted pistachios.  A serving of unsalted pistachios has only 2 mg of sodium, whereas the same amount of salted pistachios has 126 mg.

If you're planning to add a serving of nuts to your daily diet, subtract a similar number of calories from your diet to prevent weight gain. Substitute nuts for less healthy foods like cookies, ice cream, candy, soft drinks, chips and refined (white) starchy foods.

The best way to eat nuts is portion controlled - pre-portion one serving of nuts in a snack-sized bag. Don't snack directly from a large package or jar of nuts! You'll end up eating more than you intended, and more than you need.

Varieties

Pistachios are native to Asia and the Middle East where they were grown as early as 7000 BC.  Since pistachios have been grown and cultivated for thousands of years many different varieties exist.

The two main varieties available today are Kerman and Peters, which are common in North America.  Other varieties differ in how easily their shell opens and the size of the kernel.

Despite the common misconception that red pistachios are different from their green counterpart, the red colour is actually dye, not a natural pigment.  Dyed pistachios are coloured to hide their imperfections.  Green pistachios on the other hand are natural; the green colour comes from chlorophyll in the plant.

While dried pistachios are most popular, fresh pistachios are also common in some parts of the world where they're cultivated.

Buying

Pistachios can be found in stores year round.  They're available raw, roasted and salted, in the shell or shelled.

Whether you prefer to buy pistachios in their shell, or as kernels, make sure you buy a high quality product. Choose nuts that have a hard shell and an intact kernel.  In general, the greener the kernel the fresher the nut.

Choose pistachios that have their shell open at one end.  A closed shell is a sign the nut was picked prematurely.

If buying pistachios in bulk, buy nuts from a reputable store that has a high turnover of product.  A good whiff of the nuts will help determine their freshness - if they smell off, they've likely gone rancid due to their high fat content.  Avoid any nuts that have visible mold on them.

If you want to avoid food colouring, opt for green pistachios instead of red pistachios.

Storing

Because of their high fat content and open shell, pistachios, like all nuts, are susceptible to going rancid. To prolong their freshness store pistachios in a cool, dark, dry place. Exposure to light, heat and moisture for an extended period of time will decrease their shelf life.

Pistachios can be stored in a sealed container in the fridge for up to 6 months, or the freezer for up to 12 months.  If refrigerated or frozen nuts have lost their crunch, simply place them on a baking sheet and roast for 5 minutes at 375°F before consuming.

Preparing

When eating pistachios from the shell, split the shell and eat the small kernel inside.  The kernel may have a thin skin on it that can be eaten or removed before eating.  If you find a nut in a shell that doesn't pry apart easily, simply use a nutcracker to open it up.

Eating

Pistachios taste great when eaten right out of the shell, or added to prepared dishes.  They're commonly added to sweet dishes including baklava and ice cream.  Due to their healthy fat profile, pistachios are a great addition to breakfast, lunch, dinner and snacks.
