Complete Protein: Pistachios are one of the only tree nuts recognized as a complete protein, containing all 9 essential amino acids. This makes them a premium ingredient for plant-based and high-protein product formulations.
Lowest Calorie Nut: At 160 calories per ounce, pistachios have fewer calories than almonds (164), cashews (157 but less protein), walnuts (185), or pecans (196).
Heart-Healthy Fats: 90% of pistachio fat is unsaturated (mono + poly). Rich in oleic acid — the same heart-healthy fat found in olive oil.
Eye Health: Highest lutein and zeaxanthin content of any tree nut — antioxidants linked to macular degeneration prevention.
