Pistachios, like most nuts, are a healthy snack when eaten in moderation, and their fat content can help stave off hunger pangs. If you need more reasons to pick up a bag of pistachios, consider that pistachios can help reduce the risk of heart disease. They are rich in the amino acid arginine, phytosterols and unsaturated fat – all of which promote heart health.
Pistachios are a good source of polyphenol antioxidants, which protect against oxidative stress and inflammation.
They also can promote eye health. Pistachios have high levels of the carotenoids lutein and zeaxanthin, which can reduce the risk of age-related macular degeneration.
Another good reason to eat pistachios is their fiber content. One ounce of pistachios (about 47 nuts) has three grams of dietary fiber – more than a half cup of spinach and the same amount as an orange or apple.
