The Protein Profile of Brussels Sprouts
Brussels sprouts contain a moderate amount of protein for a green vegetable, with a cup of cooked sprouts offering around 4 grams. While this contributes to daily protein needs, it is considered an "incomplete" protein, meaning it lacks sufficient amounts of all essential amino acids. Combining Brussels sprouts with complementary protein sources throughout the day, like whole grains, helps ensure a complete amino acid intake, especially important for those on plant-based diets.
Brussels Sprouts vs. Other Protein-Rich Vegetables
Comparing Brussels sprouts to other plant foods reveals they offer a good protein amount for a non-starchy vegetable but are not as protein-dense as legumes or soy products. Legumes such as lentils and edamame are significantly higher in protein.
Protein and Fiber Comparison: Brussels Sprouts vs. Other Plant Foods
| Food (1 cup, cooked) | Protein (g) | Fiber (g) | Key Vitamins | Complete Protein? |
|---|---|---|---|---|
| Brussels Sprouts | ~4-5 | ~4 | Vitamins K, C | No |
| Lentils | ~18 | ~16 | Folate, Iron | No |
| Edamame | ~18 | ~8 | Vitamin K, Folate | Yes (Soy) |
| Green Peas | ~9 | ~9 | Vitamins A, C, K | No |
| Broccoli | ~4 | ~5 | Vitamins K, C | No |
This comparison highlights that while Brussels sprouts contribute protein and are rich in other nutrients like fiber, they function best as part of a varied diet alongside primary protein sources.
The Incomplete Protein Puzzle: What It Means for Your Diet
The body can pool amino acids from different foods eaten throughout the day. This means you don't need to combine incomplete proteins at every meal. A varied diet that includes Brussels sprouts along with legumes, nuts, seeds, and whole grains ensures you get all essential amino acids over time. For example, pairing Brussels sprouts with quinoa, a complete protein, creates a nutritionally balanced dish.
Maximizing Your Protein Intake with Brussels Sprouts
Brussels sprouts can be incorporated into meals to boost both protein and flavor. Pairing them with other protein-rich ingredients is a simple strategy.
Delicious Ways to Boost Protein in Your Brussels Sprouts Dishes
- Add Nuts and Seeds: Toss roasted sprouts with nuts like walnuts or almonds.
- Combine with Legumes: Add sprouts to lentil soup or chickpea curry.
- Include Soy Products: Mix shaved sprouts into a tofu or tempeh stir-fry with brown rice.
- Use as a Salad Base: Create a slaw with shredded sprouts, edamame, and a nutty dressing.
- Pair with Grains: Serve roasted sprouts with quinoa or farro.
- Make it a Main Course: Try a Brussels sprouts salad with chickpeas and a Greek yogurt dressing.
Beyond Protein: A Nutritional Powerhouse
Brussels sprouts are packed with nutrients beyond protein. They are high in fiber, supporting digestion and satiety. They are also an excellent source of Vitamin C for immune health and Vitamin K for blood clotting and bone health. Furthermore, Brussels sprouts contain antioxidants like kaempferol and glucosinolates, linked to anti-inflammatory and potential cancer-protective benefits. Their rich nutrient profile makes them a valuable addition to a balanced diet, even if not a primary protein source.

Conclusion: A Valued Contributor, Not a Protein King
Brussels sprouts provide a good amount of protein for a vegetable but are not a primary source compared to legumes or animal products. They are an excellent addition to a healthy diet, particularly when combined with other protein-rich foods to achieve a complete amino acid profile. Their significant contribution lies in their high levels of fiber, vitamins K and C, and potent antioxidants, making them a nutrient-dense food that supports overall health.
