Pistachios are widely celebrated for their delightful flavor and satisfying crunch, but their nutritional powerhouse status is equally impressive. The question, "what percent of pistachio is protein?" reveals a powerful truth about this popular nut (technically a seed): it is a surprisingly rich source of vegetable protein, making it an excellent addition to any diet, particularly plant-based ones. Beyond just being high in protein, recent findings have identified roasted pistachios as a complete protein, providing all nine essential amino acids needed by the human body.
The Protein Power of Pistachios
Based on data from the United States Department of Agriculture (USDA), a 100-gram portion of raw pistachios contains approximately 20.2 grams of protein. This translates to about 20% of its total weight being protein. For a standard 1-ounce (or 28-gram) serving, that means you're getting around 6 grams of protein, a substantial amount for a single snack. When compared to other common nuts, pistachios hold their own, providing a competitive protein punch alongside a diverse nutrient profile.
Pistachio's Unique Complete Protein Status
While many plant-based proteins are considered "incomplete," lacking one or more of the nine essential amino acids, recent research has changed the game for roasted pistachios. A study published in 2023 highlighted that roasted pistachios contain sufficient levels of all nine essential amino acids, granting them the title of a 'complete protein' for those aged five and over. This discovery is particularly important for vegans, vegetarians, and those seeking to diversify their protein sources, as it removes the need to combine multiple plant foods to create a complete protein profile.
Beyond Protein: Other Nutritional Perks
While their high protein content is a major benefit, pistachios offer a complete nutritional package. They are rich in healthy fats, fiber, vitamins, and minerals that contribute to overall well-being.

Comparing Pistachio's Protein to Other Nuts
When considering protein content, it's useful to see how pistachios stack up against other popular nuts. The following table provides a breakdown per 100 grams, based on USDA data, highlighting the value of pistachios.
| Nut | Protein Content (per 100g) | Calorie Content (per 100g) | Notes |
|---|---|---|---|
| Pistachios (Raw) | ~20.2 g | ~560 kcal | Considered a complete protein when roasted. |
| Almonds (Raw) | ~21.1 g | ~579 kcal | Slightly higher protein, but pistachios have more antioxidants. |
| Cashews (Raw) | ~18.2 g | ~553 kcal | Lower protein than pistachios per 100g. |
| Walnuts (Raw) | ~15.2 g | ~654 kcal | Lower protein and higher calorie count than pistachios. |
From this comparison, it is clear that pistachios offer a competitive protein density alongside a lower calorie count per serving compared to some other nuts, making them a satisfying and efficient protein source.
Incorporating Pistachios into Your Diet
Pistachios offer numerous ways to be included in your diet. Enjoy them as a snack, sprinkle them on meals, use them in cooking, or blend into nut butter.

Conclusion
Pistachios are an excellent and versatile source of protein. While pistachios are a highly nutritious food, individuals with tree nut allergies should avoid them.
