The Nutritional Breakdown of a Cup of Broccoli
Broccoli is a popular cruciferous vegetable known for its impressive nutritional profile. The exact caloric and protein content can vary slightly depending on whether it is consumed raw or cooked. Understanding these differences can help you make informed dietary choices.
Raw Broccoli Nutrition
According to the USDA, one cup of raw, chopped broccoli, weighing around 91 grams, contains approximately 31 calories and 2.6 grams of protein. This low-calorie count is largely due to its high water content, which makes up almost 90% of its weight. The small amount of carbohydrates present mostly comes from dietary fiber and sugars. A single cup provides a significant amount of your daily vitamin C and K needs, along with other essential nutrients like folate and potassium.
How Cooking Changes Calories and Protein
The way broccoli is prepared can slightly influence its final nutritional makeup, particularly because some water content is lost during cooking, which concentrates the nutrients. This is why a cup of cooked broccoli may contain slightly more calories and protein than a cup of raw broccoli. For example, a cup of boiled, chopped broccoli is around 27 calories and 1.9 grams of protein. The slight decrease in total nutrients with boiling, particularly vitamin C, is due to some leaching into the water. Other cooking methods, such as steaming, are better at preserving nutrients.
Raw vs. Cooked: A Nutritional Comparison Table
Here is a side-by-side comparison of the approximate nutritional values for one cup of raw versus boiled broccoli, based on data from the USDA:
| Nutrient | Raw (per 1 cup, chopped) | Boiled, Drained (per 1 cup, chopped) |
|---|---|---|
| Calories | ~31 kcal | ~27 kcal |
| Protein | ~2.6 g | ~1.9 g |
| Carbohydrates | ~6 g | ~5.6 g |
| Dietary Fiber | ~2.4 g | ~2.6 g |
| Fat | ~0.3 g | ~0.3 g |
| Vitamin C | ~81 mg (High) | ~51 mg (Good) |
| Vitamin K | ~92 mcg (High) | ~110 mcg (High) |
Beyond the Numbers: Other Health Benefits
While the calorie and protein numbers are useful, they only tell part of the story. Broccoli offers a host of other health benefits that make it an excellent choice for a well-rounded diet.
High in Fiber
The high fiber content in broccoli is beneficial for digestive health, promoting regular bowel movements and supporting a healthy gut microbiome. This fiber also contributes to a feeling of fullness, which can help reduce overall calorie intake and support weight management.
Antioxidant Powerhouse
Broccoli is loaded with potent antioxidants and other bioactive compounds. One notable compound is sulforaphane, which may help protect against various types of cancer and reduce inflammation. It also contains antioxidants like lutein and zeaxanthin, which are particularly beneficial for eye health.
Vitamin and Mineral Rich
This green vegetable provides a wealth of other vitamins and minerals essential for bodily function.
- Vitamin C: Important for immune function and skin health.
- Vitamin K: Crucial for blood clotting and bone health.
- Folate (Vitamin B9): Needed for normal cell function and tissue growth.
- Potassium: Helps regulate blood pressure.
Cooking Methods Matter for Maximum Nutrients
To get the most nutritional value from your broccoli, the cooking method is important. Here are some of the best ways to prepare it:
- Steaming: This method is highly recommended as it preserves the heat-sensitive vitamin C and sulforaphane compounds better than boiling.
- Light Stir-frying: A quick stir-fry can help retain many of the vegetable's benefits while adding flavor. Research suggests light stir-frying can even maximize sulforaphane levels when combined with a pre-chop.
- Roasting: Roasting brings out a delicious, nutty flavor and is another excellent way to cook broccoli with minimal nutrient loss, as long as it's not overcooked.
- Raw: Eating it raw is a great option for getting maximum vitamin C and sulforaphane.
Versatile Ways to Enjoy Broccoli
Including broccoli in your diet is easy given its versatility. Try these simple preparation ideas:
- As a side dish: Lightly steamed or roasted broccoli with a sprinkle of salt and pepper makes a perfect accompaniment to almost any meal.
- In salads: Add raw, chopped broccoli to your favorite salads for extra crunch and nutrients.
- In stir-fries: Combine broccoli with other vegetables and a protein source for a quick and healthy stir-fry.
- Blended into soup: Create a creamy broccoli soup for a comforting and nutritious meal.
- As a snack: Dip raw broccoli florets in hummus or a low-calorie dressing for a healthy and satisfying snack.
Conclusion: A Nutrient-Packed Powerhouse
A cup of broccoli, whether raw or cooked, offers a low-calorie, moderate protein solution that is rich in vitamins, fiber, and potent antioxidants. For roughly 30 calories, you get a substantial serving of a nutrient-dense vegetable that supports everything from digestive health to immune function. While minor nutritional differences exist between raw and cooked versions, incorporating broccoli into your diet in any form is a smart choice for overall health and wellness. For maximizing certain sensitive nutrients, steaming or eating it raw are your best bets, but the overall health benefits make it a winner no matter how you prefer to enjoy it. Healthline
Frequently Asked Questions
Q: Is raw or cooked broccoli better for you?
A: Both raw and cooked broccoli are healthy, but they offer slightly different nutritional profiles. Raw broccoli retains more heat-sensitive vitamin C, while cooking can make certain antioxidants more bioavailable. For maximum benefits, it's best to eat a combination of both.
Q: Can broccoli help with weight loss?
A: Yes, broccoli can aid in weight loss. It is low in calories but high in fiber and water, which helps you feel full and satisfied, thereby reducing overall calorie intake.

A: Broccoli is particularly rich in vitamins C and K, and also contains good amounts of folate (B9), vitamin A, and other B vitamins.
Q: How does cooking affect broccoli's nutrients?
A: Some nutrients, like vitamin C, can be lost during cooking, especially with methods like boiling. Steaming or light stir-frying generally preserves nutrients better than boiling.
Q: Is broccoli a good source of protein for a vegetable?
A: Yes, for a vegetable, broccoli contains a decent amount of protein, providing around 2.6 grams per raw cup. However, you should still include other protein sources in your diet to meet your daily needs.
