The Protein Content of Broccoli
When considering if broccoli is a rich source of protein, it's important to look at the numbers. Raw broccoli is approximately 90% water by weight. A typical 100-gram serving of raw broccoli contains about 2.8 grams of protein. A standard one-cup (91g) serving of raw, chopped broccoli offers around 2.6 grams of protein. While this is a modest amount, it's notable for a vegetable, but it falls far short of what is considered a 'rich' protein source compared to legumes, nuts, or animal products.
The Impact of Cooking on Broccoli's Protein
Cooking can slightly change the protein content of broccoli due to changes in water weight. For instance, when broccoli is boiled, its water content can increase, meaning the protein concentration per 100 grams might decrease. According to the University of Rochester Medical Center, a cup of boiled and drained broccoli has slightly less protein (2.32g) than a cup of raw broccoli (2.57g). However, the overall amount of protein remains relatively consistent per serving.
Broccoli's Complete Nutritional Profile
While protein is often the focus, broccoli's true strength lies in its comprehensive nutritional benefits. It is packed with essential nutrients that contribute significantly to a healthy diet. This vegetable is a treasure trove of:
- Vitamins C and K: A single cup of raw broccoli provides an impressive amount of both vitamins C and K, which are crucial for immune function, skin health, and blood clotting.
- Dietary Fiber: Broccoli is a great source of fiber, which aids in digestion, promotes a healthy gut, and contributes to a feeling of fullness.
- Antioxidants: As a cruciferous vegetable, it contains various antioxidants and beneficial plant compounds that help combat inflammation and may reduce the risk of certain chronic diseases.
- Other Minerals: It also provides a good dose of folate (vitamin B9), potassium, and manganese.
Comparing Broccoli's Protein with Other Foods
To put broccoli's protein content into perspective, let's compare it to other common protein sources, both plant-based and animal-based. This comparison helps illustrate its role in a balanced diet.
| Food (100g serving) | Protein (approx.) | Notes |
|---|---|---|
| Broccoli (raw) | 2.8g | Excellent source of Vitamins C & K, fiber |
| Chicken Breast (cooked) | ~31g | A dense, complete protein source |
| Lentils (cooked) | 9g | High in protein, fiber, and iron |
| Spinach (cooked) | 2.86g | Rich in iron and vitamin K |
| Chickpeas (cooked) | 14.5g | A versatile legume rich in fiber |
How Broccoli Fits into a Protein-Rich Diet
For those following a plant-based diet, relying solely on vegetables like broccoli for protein would be inefficient. A balanced approach is key. You can maximize your protein intake by combining different plant foods throughout the day, a concept once known as 'complementary proteins'. For example, pairing broccoli with a side of lentils or chickpeas provides a more substantial protein meal. Many plant-based options exist to boost protein intake significantly, including tofu, tempeh, beans, and nuts.
Practical Ways to Boost Protein with Broccoli
- Add legumes: Mix steamed broccoli florets into a lentil soup or a chickpea salad.
- Combine with grains: Serve roasted broccoli with quinoa or brown rice for a complete amino acid profile.
- Incorporate nuts and seeds: Sprinkle a handful of almonds or sunflower seeds over a broccoli and pasta dish.
- Blend into sauces: Create a nutrient-dense and flavorful pesto-like sauce with blended broccoli, cashews, and basil.
Conclusion: More Than Just Protein
So, is broccoli a rich source of protein? The definitive answer is no; it provides a modest amount. However, judging this vegetable purely on its protein count would be a mistake. Its value lies in its high concentration of other vital nutrients, including vitamins, fiber, and antioxidants, which are crucial for overall health and well-being. Broccoli is a powerful, nutrient-dense food that plays a supporting role in a high-protein diet, not a leading one. By combining it with other protein-rich sources like legumes, nuts, and whole grains, you can easily meet your daily protein needs while reaping the full spectrum of its health benefits.

A Final Word on a Healthful Diet
Ultimately, a healthy diet is about variety and balance. Incorporating a wide array of vegetables, including cruciferous champions like broccoli, alongside other nutrient-dense foods will provide your body with the fuel it needs to thrive. Focus on the total nutritional package rather than getting hung up on a single macronutrient.
