The Protein in Ground Walnuts: A Closer Look
A single tablespoon of ground English walnuts typically provides around 1.1 to 1.9 grams of protein, though the precise amount can vary. The discrepancy often depends on the walnut variety and how finely it is ground. For instance, USDA data for ground black walnuts shows a protein content of 1.88 grams per tablespoon, which is a slightly higher figure compared to some estimates for English walnuts. This is because a more finely ground product can be packed more densely into the same volume measurement. Regardless of the small variations, ground walnuts offer a convenient, plant-based protein source for those looking to enhance their nutritional intake with a simple spoonful. Their versatility makes them an ideal addition to a wide range of meals, from breakfast items to dinner entrees.
Nutritional Profile Beyond Protein
Walnuts are celebrated not only for their protein but also for their comprehensive nutritional value. A tablespoon-sized serving adds more than just macronutrients to your food. Here’s what else you get:
- Heart-Healthy Fats: Walnuts are a premier source of omega-3 alpha-linolenic acid (ALA), a crucial fatty acid for heart health that can reduce inflammation. In fact, they are the only nut to contain significant amounts of ALA.
- Rich in Antioxidants: These nuts contain a high level of antioxidants, including gamma-tocopherol, a form of vitamin E, which helps protect the body from oxidative damage.
- Key Minerals: Ground walnuts provide essential minerals such as magnesium, phosphorus, and manganese, all vital for bone health and metabolic function.
Ground Walnuts vs. Other Ground Nuts: A Protein Comparison
To put the protein content of ground walnuts into perspective, here is a comparison table showing the approximate protein per tablespoon for several popular ground nuts. It's important to remember that these are average figures and actual protein counts can vary slightly depending on the specific product, processing, and how densely the nut is packed.
| Nut (Ground) | Approx. Protein per 1 Tbsp |
|---|---|
| Walnuts (English/Black) | 1.1 - 1.9g |
| Almonds (Blanched) | ~2g |
| Peanuts (Dry Roasted) | ~2g |
| Cashews (Dry Roasted) | ~1g |
Easy Ways to Add Ground Walnuts to Your Diet

Conclusion
While a single tablespoon of ground walnuts provides a modest amount of protein, ranging from 1 to 2 grams, its overall nutritional profile makes it a highly beneficial food. Its contribution of healthy fats, particularly omega-3s, and antioxidants far exceeds its simple protein content. The convenience of using ground walnuts makes them an effortless way to add a nutrient-dense ingredient to your daily meals, supporting heart health and providing essential vitamins and minerals. For those seeking comprehensive information on the nutrient composition of various nuts, sources like the National Institutes of Health offer detailed studies.
