Pistachios are energy-dense like all nuts, with 572 kcal (2393 kJ) per 100 g dry roasted, and most of that energy comes from fat, largely the monounsaturated kind. They also provide about 21 g of protein and 10 g of fibre per 100 g, and are notably high in potassium, vitamin B6 and copper.

Things worth knowing

• One ounce (28 g) is about 49 kernels and 162 kcal (678 kJ), so each kernel is roughly 3 to 4 kcal.
• Raw pistachios are almost identical at 560 kcal per 100 g; roasting removes a little water rather than adding calories. Salted dry-roasted pistachios carry about 428 mg of sodium per 100 g.
• Shells add weight but no calories, so when weighing in-shell pistachios, remember that the edible kernels are only part of the total.
• A 1 oz serving supplies about 285 mg of potassium and 0.32 mg of vitamin B6, around a fifth of the B6 Daily Value.
