Calories in Pistachios

According to the United States Department of Agriculture and the Pistachio Health Organization, a standard 1-ounce serving of pistachios is equivalent to 49 kernels and 158 calories. This means a reduced serving of 100 calories is equivalent to about 30 pistachio kernels. An equivalent 100-calorie snack might be 10 almonds, cashews or walnuts, or 16 peanuts.

Whether you’re choosing the reduced serving or the standard serving, the calories in pistachios make them a healthy choice and provide you with a lot more nuts per calorie than some others. In comparison, a standard serving of cashews is equivalent to only 18 nuts, and a standard serving of walnuts equals only 14 nut halves. The caloric intake between types of nuts can be similar, though. For example, in a standard serving, the calories in peanuts equal 160. This is about the same as the standard serving of pistachios.

Pistachio Nutrition Facts

Pistachios are rich in beneficial nutrients. They contain fiber, protein and healthy fats that are good for your heart. The fiber and protein in pistachios makes them a healthy snacking option that may be more filling compared to carbohydrate-rich snacks like chips, crackers and pretzels.

According to the USDA, pistachios are rich in calcium, iron, vitamin A and vitamin C. They are also a good source of copper, manganese, phosphorus, thiamin and vitamin B-6. Like many nuts and seeds, pistachios are sold after roasting and salting, making the sodium content of some brands high. Pistachios alone typically have no sodium content — literally, zero milligrams of sodium. However, an ounce of pistachios that have been salted can contain as much as 115 milligrams of sodium.

Why Eat Pistachios?

If the beneficial vitamins and minerals in pistachios aren’t enough to entice you, pistachios have also been linked to a wide range of health benefits.
