With public awareness of nuts being high in fat has given nuts a bad nutritional reputation. Taking another look at the nutritional value of pistachios and nuts in general, we see that not only are nuts nutritious, their fats are healthy for your cardiovascular system and more.

What are Pistachios?

Pistachios come from the Pistacia vera tree which is native to the Mediterranean, Middle east, and Central Asia. The Pistachio tree is from the same family as the cashew tree. It produces small avocado green colour nuts.

They have been eaten for thousands of years dating back to 6750 BC, as confirmed by archaeological digs in Jarmo, Iraq.

Pistachio shells are unique in that they start off green and as they ripen they turn a yellowish red and split open. This is why Pistachio shells are split open when you buy them.

Pistachios, like other nuts, are a rich source of antioxidants, minerals, protein and healthy fats.

Health Benefits of Pistachios

When enjoyed as a snack, pistachios are packed with healthy fats and fibre, helping curb your appetite and support weight management. A 2010 study published in the Journal of the American College of Nutrition found that, over a 12-week period, regular pistachio consumption led to reductions in body mass index and triglyceride levels. Just one ounce of these nuts provides about 160 calories, along with 6 grams of protein, 3 grams of fibre, and 15 grams of healthy fats.

In terms of nutrients, they are rich in potassium and vitamin K, both essential for cardiovascular health and maintaining electrolyte balance. They also offer a significant portion of your daily requirements for vitamin B6, thiamines, phosphorus, and magnesium. Notably, they are high in oleic acid, which helps lower LDL (bad) cholesterol while boosting HDL (good) cholesterol, thereby improving overall lipid profiles and reducing cardiovascular risk.

Research from the American Journal of Clinical Nutrition in 2008 showed that incorporating pistachios into a reduced-calorie diet can significantly lower cholesterol levels. They are also abundant in L-arginine, an amino acid that helps keep arterial walls flexible and reduces the risk of blood clots. Additionally, pistachios are rich in vitamin E, an antioxidant that protects cells from oxidative damage and supports arterial health.

Moreover, these nuts are loaded with essential minerals such as calcium, magnesium, iron, potassium, and zinc, all crucial for maintaining healthy bones, muscles, and enzymatic functions. Pistachios are particularly high in copper, providing over 140% of the daily recommended intake per 100 grams, which supports nerve health, red blood cell formation, and metabolism.

Finally, these nuts are an excellent source of B vitamins, including riboflavin, niacin, thiamine, pantothenic acid, vitamin B6, and folate. These vitamins play a vital role in energy metabolism, hormone regulation, and overall nerve function.

How To Use Pistachios

Pistachios are a great snacking nut. A quick handful along with a piece of fruit makes for a perfect combination of protein and fat....along with all the antioxidants, vitamins and minerals Pistachios offer.

Add Pistachios to salads or as a nut butter on flat breads or enjoy in deserts, on yogurt or on hot cereals.

Shopping For Quality Nuts

Pistachios should taste fresh – a rich nutty buttery flavour. If the flavour is sharp or bitter it is likely that the fats have gone rancid. They can be found in their shells or shelled. They are healthiest bought still in their shells.

The fragile oils in Pistachios are kept freshest when they are left raw. And to continue preservation they are ideally stored in the fridge. Once shelled or roasted they can go rancid quickly.

Further, it is best to eat Pistachios without salt added. Many studies have confirmed the use of salt is not advised as it can contribute to swelling and elevated blood pressure.

Alternatives

Pistachios are tree nuts and so can be allergenic to some people. If you know or suspect you may have a tree nut allergy you will want to avoid Pistachios.

If you are unsure, food allergy and sensitivity testing can be done through your ND or MD.

Alternatives to Pistachios are seeds like pumpkin, sesame, chia, and sunflower. Raw seeds can also provide healthy fats, minerals and antioxidants to benefit your health.
