Around 15% of the calories in roasted pistachios come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 31 nuts in the database, roasted pistachios ranks 4th by protein per serving, and 437th out of all 796 foods on the site. Set against almond butter, another nut entry in the database, a serving carries about 0.8 g less protein (almond butter has 6.7 g per 2 tbsp).
