Selecting, storing & prepping pistachios
- Selecting
- A naturally split shell is a sign of ripeness in in-shell pistachios — pistachios are harvested when the shell cracks open on its own, so a fully closed shell often means the nut is underripe.
- Storing
- In-shell pistachios keep about 3 months at room temperature in a sealed container; shelled pistachios go rancid faster once exposed to air and keep longer refrigerated or frozen, up to a year.
- Prepping
- The natural split in the shell makes pistachios one of the easier nuts to open by hand — just widen the existing crack with a thumbnail or the edge of another shell.
Storage guidance from the USDA FoodKeeper database (FSIS, Cornell University, and the Food Marketing Institute).

Key metrics
Nutrient density
Per 100 kcal, pistachios delivers about 5% of a Daily Value on average across 22 beneficial nutrients. The score is its percentile for that measure among the 177 foods in our database — higher means more nutrition per calorie. How this is calculated.
- More potassium than 100% of foods · 100% of nuts & seeds
- More fiber than 95% of foods · 79% of nuts & seeds
- More iron than 93% of foods
Density counts protein, fiber, and vitamins and minerals (not fat, sodium, or sugar), each capped so a single nutrient can’t dominate, with a calorie floor so very-low-calorie foods aren’t overstated. It measures nutrition per calorie within our database — a useful guide, not a complete verdict on how “healthy” a food is.
