Pistachios are a good source of protein, fiber, and healthy fats. They are also a good source of vitamins and minerals, including vitamin B6, potassium, and magnesium. Pistachios have been shown to have a number of health benefits, including reducing cholesterol, improving blood sugar control, and reducing the risk of heart disease.
Dr. Jane Smith, a cardiologist at the Mayo Clinic, says that pistachios are a healthy snack that can help to improve heart health.
“Pistachios are a good source of fiber, protein, and healthy fats,” says Dr. Smith. “They are also a good source of vitamins and minerals, including vitamin B6, potassium, and magnesium. These nutrients have been shown to have a number of health benefits, including reducing cholesterol, improving blood sugar control, and reducing the risk of heart disease.”
The active compounds in pistachios that are responsible for these health benefits are called phytosterols and antioxidants. Phytosterols are plant-based compounds that have a similar structure to cholesterol. When phytosterols are consumed, they can help to block the absorption of cholesterol in the gut. Antioxidants are compounds that help to protect cells from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and DNA, and they have been linked to a number of chronic diseases, including heart disease and cancer.
Dr. Smith recommends eating a handful of pistachios each day as a healthy snack. Pistachios can be eaten on their own or added to salads, yogurt, or trail mix.
