About these values

The record is shelled pistachios, dry roasted without salt, so the weights do not include shells. The USDA record is "Nuts, pistachio nuts, dry roasted, without salt added" (SR Legacy, FDC ID 170185). It gives 21.05 g of protein and 572 kcal per 100 g.

Protein in a portion is its weight times the protein per 100 g, divided by 100. For 1 oz of pistachios (49 kernels): 28.35 × 21.05 ÷ 100 = 6.0 g. Values on this page are rounded to 0.1 g.

A packaged food's own label can differ from the USDA average. When you have the label, its numbers are the ones for that product.
