1. What is the Protein Content of Broccoli?
The amount of protein in broccoli can vary depending on whether it’s raw or cooked. Let’s break it down:
- Raw Broccoli: A 1-cup (91-gram) serving of raw broccoli contains approximately 2.6 grams of protein.
- Cooked Broccoli: A 1-cup (156-gram) serving of cooked broccoli contains about 3.7 grams of protein.
While broccoli is not as protein-dense as foods like meat, eggs, or legumes, it’s a significant source of protein, especially when considering its low-calorie count and high nutrient content.
2. Nutritional Profile of Broccoli Beyond Protein
Broccoli is a nutritional powerhouse that offers far more than just protein. Here’s a detailed look at its key nutrients:
2.1. Vitamins
- Vitamin C: Broccoli is an excellent source of vitamin C, an antioxidant that supports immune function, skin health, and iron absorption. A 1-cup serving of cooked broccoli provides over 100% of the daily recommended intake of vitamin C.
- Vitamin K: Essential for blood clotting and bone health, vitamin K is abundant in broccoli. A 1-cup serving provides a substantial portion of your daily needs.
- Vitamin A: As mentioned earlier, broccoli contains beta-carotene, which the body converts into vitamin A, important for vision, immune function, and cell growth.
