The Raw Protein Showdown: Per 100 Grams
When we look at the protein content in its raw, unprocessed state, the difference between broccoli and spinach is minimal and almost negligible. Both vegetables offer a small, but valuable, amount of plant-based protein. According to data from nutritional sources, 100 grams (about 3.5 ounces) of raw spinach contains approximately 2.9 grams of protein. For the same 100-gram serving, raw broccoli provides roughly 2.8 grams of protein. This shows that on a strict weight-for-weight basis, raw spinach has a marginal edge over raw broccoli.
A Closer Look: Protein Per Cup
However, focusing solely on a 100-gram comparison can be misleading because most people consume these vegetables in different portion sizes. The volume of a standard 'cup' serving is where the comparison truly changes. A cup of raw, chopped broccoli weighs significantly more (around 88 grams) than a cup of raw, loose-leaf spinach (around 25 grams). Due to this weight difference, the protein intake per cup is dramatically different:
- One cup of chopped raw broccoli provides about 2.5 grams of protein.
- One cup of raw spinach contains only about 0.7 grams of protein.
The Effect of Cooking on Protein
Cooking affects the protein concentration of both vegetables by reducing their high water content. Spinach, which is over 90% water, wilts down to a fraction of its original volume when cooked. This process concentrates its nutrients, including protein. A single cup of cooked spinach can deliver a substantial 5 to 6 grams of protein, a figure that far surpasses its raw counterpart. Similarly, cooking broccoli also concentrates its nutrients, leading to a higher protein content per cup of cooked vegetable. One cup of cooked broccoli provides approximately 4 grams of protein, making both cooked vegetables superior protein sources per cup compared to their raw forms.

| Feature | Raw Broccoli | Raw Spinach | Cooked Broccoli | Cooked Spinach |
|---|---|---|---|---|
| Protein per 100g | ~2.8g | ~2.9g | ~3.8g | ~5.3g |
| Protein per Cup | ~2.5g | ~0.7g | ~4g | ~5-6g |

More Than Just Protein: Other Nutrients
While protein is important, it's not the only nutrient worth considering. Both broccoli and spinach are nutritional powerhouses, each with its unique profile. Understanding their other benefits can help you decide which one best fits your overall dietary needs.
Health Benefits of Broccoli
Broccoli, a cruciferous vegetable, is particularly known for its high vitamin C and vitamin K content. It also provides a significant amount of dietary fiber, which is crucial for digestive health. The compound sulforaphane, found in broccoli, has been linked to numerous health benefits, including antioxidant and anti-inflammatory properties. These properties can support overall immune function and help the body fight against cellular damage.
Health Benefits of Spinach
As a leafy green, spinach is packed with other vital nutrients. It is an excellent source of iron, manganese, magnesium, and folate. Spinach is also notably rich in vitamin A and vitamin K, with one cup of raw spinach providing over 100% of the daily recommended intake for vitamin K. The high antioxidant content, including beta-carotene and lutein, makes spinach beneficial for eye health and for reducing inflammation.
How to Incorporate Both Greens Into Your Diet
Including both broccoli and spinach in your meals is an easy way to get a wide array of vitamins, minerals, and plant-based protein. The key is knowing how to prepare them to maximize their nutritional value and taste.
Here are some simple ways to add both to your weekly meals:
- Smoothies: Toss a handful of raw spinach into your morning fruit smoothie for a nutritional boost with a barely-there taste. For a richer, cooked spinach option, lightly steam it before blending.
- Salads: Use raw, delicate spinach leaves as a base for a fresh salad. Top with steamed broccoli florets for texture and a different nutritional profile.
- Stir-fries: Both vegetables are excellent additions to stir-fries. Add broccoli early to allow it to cook, and toss in spinach towards the end to let it wilt.
- Soups: Blend steamed spinach into a creamy soup base or add chopped broccoli florets for a heartier, more filling soup.
- Pasta Dishes: Sautéed spinach and broccoli can be mixed into any pasta sauce or tossed with noodles and olive oil for a quick and nutritious meal.
- Roasted Sides: For a delicious side dish, roast broccoli florets with a little olive oil, garlic, and your favorite seasonings. You can also mix in some chopped spinach during the last few minutes of roasting.
Conclusion
So, which has more protein, broccoli or spinach? The answer depends on how you measure it. Per 100 grams (raw), spinach has a very slight edge, but per typical serving cup, cooked spinach contains significantly more concentrated protein than cooked broccoli due to the different volumes and water content. The most important takeaway, however, is that both are incredibly healthy vegetables. Broccoli provides more fiber and Vitamin C per 100g, while spinach is a better source of iron, folate, and Vitamin K. For optimal health and a wider range of nutrients, incorporating both vegetables into your diet is the best strategy. The differences are so minor that your choice should ultimately come down to your personal taste, cooking method, and overall dietary goals. For reliable nutritional data, consulting authoritative sources like the USDA is always recommended.
