Pine nuts, also called piñón (Spanish: [piˈɲon]), pinoli (Italian: [piˈnɔːli]), or pignoli, are the edible seeds of pines (family Pinaceae, genus Pinus). About 20 species of pine produce seeds large enough to be worth harvesting; in other pines, the seeds are also edible, but are too small to be of notable value as a human food.

Pine nuts are prominently consumed in several cuisines worldwide, especially as part of Brazilian cuisine, Middle Eastern Cuisine, Chinese cuisine, Italian cuisine, Japanese cuisine, Korean cuisine, Mongolian cuisine, New Mexican cuisine, Russian cuisine, and various Native American cuisines. This widespread geographical consumption makes it recognizable within the context of global cuisine.

Eating peanuts and tree nuts (e.g., walnuts, almonds, and pistachios) may reduce the risk of heart disease when consumed as part of a diet that is nutritionally adequate and within calorie needs. Because nuts and seeds are high in calories, eat them in small portions and use them to replace other protein foods, like some meat or poultry, rather than adding them to what you already eat. In addition, choose unsalted nuts and seeds to help reduce sodium intakes.
