Macronutrient Breakdown: Fueling Your Body
One of the first things to consider when looking at the nutritional value of 1 cup of cooked Brussels sprouts is its macronutrient profile. For a relatively low-calorie vegetable, it provides a surprising amount of beneficial components. A standard 1-cup serving of boiled, drained Brussels sprouts contains approximately 56 calories.
Carbohydrates and Fiber
Carbohydrates make up the majority of the vegetable's energy content, with about 11 grams per cup. This includes a significant amount of dietary fiber, around 4 grams, which is crucial for a healthy digestive system. Fiber promotes regular bowel movements, supports satiety, and can help stabilize blood sugar levels.
Protein and Fat
Cooked Brussels sprouts provide a decent amount of plant-based protein, with approximately 4 grams per cup. While not a complete protein source, it contributes to overall protein intake, which is essential for tissue repair and building muscle. The fat content is minimal, typically around 1 gram per cup, with a small portion being unsaturated fat.
A Powerhouse of Vitamins and Minerals
Beyond the basic macronutrients, the true strength of this cruciferous vegetable lies in its rich array of vitamins and minerals. The amounts can vary slightly depending on the exact cooking method, but the following are consistently abundant:
- Vitamin K: A single cup can provide well over the recommended daily intake of Vitamin K. This fat-soluble vitamin is vital for blood clotting and plays an important role in bone health.
- Vitamin C: Even after cooking, Brussels sprouts retain a substantial amount of Vitamin C, a powerful antioxidant. Vitamin C is essential for immune function, collagen production for tissue repair, and enhancing iron absorption from plant-based foods.
- Vitamin A: Contains a good percentage of the daily value for Vitamin A, important for vision and overall immune function.
- Folate (Vitamin B9): Cooked Brussels sprouts are a great source of folate, which is crucial for cell growth and DNA synthesis.
- Potassium: This mineral is important for maintaining fluid balance, nerve signals, and blood pressure regulation.
- Manganese: Essential for metabolizing carbohydrates, amino acids, and cholesterol.
- Other Nutrients: Also contains smaller amounts of magnesium, iron, phosphorus, and other B-vitamins like B6.
Key Health Benefits of Cooked Brussels Sprouts
Antioxidant and Anti-inflammatory Properties
Brussels sprouts are loaded with antioxidants that protect your cells from oxidative stress and damage caused by free radicals. This antioxidant content helps combat chronic inflammation, which is linked to conditions like heart disease, diabetes, and certain cancers. Some of the notable antioxidants include Vitamin C and alpha-lipoic acid (ALA), with studies showing ALA's potent anti-inflammatory effects.
Cancer-Protective Compounds
As a cruciferous vegetable, Brussels sprouts contain a sulfur-containing phytochemical called glucosinolate. When cooked and chewed, an enzyme called myrosinase is released, which breaks down glucosinolates into compounds called isothiocyanates. Isothiocyanates have been researched for their potential to offer protective effects against certain cancers by inhibiting tumor growth and protecting DNA. It's important to note that while promising, more research is needed to confirm these effects definitively in humans.
Supports Gut and Digestive Health
The high fiber content in cooked Brussels sprouts is a huge benefit for gut health. Fiber acts as a prebiotic, feeding the beneficial bacteria in your gut. This supports a healthy gut microbiome, which is vital for overall health and digestion. Additionally, the fiber aids in regularity, helping to prevent constipation.
Stabilizes Blood Sugar
The soluble fiber in Brussels sprouts forms a gel-like substance in the gut that slows the absorption of sugar, which can help prevent blood sugar spikes. This makes it a great food for those looking to manage blood sugar levels and reduce the risk of type 2 diabetes.
Enhances Iron Absorption
For individuals on plant-based diets, the Vitamin C content is a significant advantage. Vitamin C plays a crucial role in enhancing the absorption of non-heme iron, which is found in plant foods and is typically less absorbable than iron from animal sources.
Cooked vs. Raw: A Quick Comparison
While raw and cooked Brussels sprouts are both nutritious, there are differences in their nutritional content and bioavailability. Cooking can alter the levels of certain vitamins and can make some compounds more available.
| Nutrient | 1 cup Raw Brussels Sprouts | 1 cup Boiled Brussels Sprouts (no salt) |
|---|---|---|
| Calories | ~38 kcal | ~56 kcal |
| Fiber | ~3 g | ~4 g |
| Vitamin C | ~75 mg (83% DV) | ~97 mg (107% DV) |
| Vitamin K | ~156 µg (130% DV) | ~219 µg (182% DV) |
| Folate (B9) | ~54 µg (13% DV) | ~94 µg (23% DV) |
Note: Nutritional data can vary based on factors such as size and preparation. As the table shows, boiling can actually increase the concentration of some nutrients, but some water-soluble vitamins may leach into the water if not handled correctly.
Cooking Methods and Nutrient Retention
To get the most nutritional bang for your buck, consider your cooking method. While boiling can lead to the loss of water-soluble vitamins, roasting, steaming, or microwaving can be excellent choices. Roasting, in particular, can enhance flavor through the Maillard reaction while preserving nutrients and maximizing the beneficial isothiocyanate compounds.
Conclusion: A Nutritious Addition to Any Diet
In summary, the nutritional value of 1 cup of cooked Brussels sprouts is undeniable. They are a low-calorie, high-fiber food packed with essential vitamins like K and C, important minerals, and antioxidants. The health benefits extend beyond basic nutrition to include support for gut health, stable blood sugar, and protection against oxidative stress and inflammation. Whether you enjoy them roasted, steamed, or sautéed, incorporating Brussels sprouts into your regular diet is a simple and effective way to boost your nutrient intake. The key is to find a cooking method you enjoy to ensure these versatile and healthy vegetables become a regular feature on your plate.

Potential Considerations for Brussels Sprouts Consumption
While highly beneficial, it's worth noting some potential considerations. For some individuals, eating a large quantity of Brussels sprouts may lead to gastrointestinal issues like gas or bloating, though cooking them can make them easier to digest. Additionally, due to their high Vitamin K content, people taking blood-thinning medication like warfarin should maintain a consistent intake and consult their doctor to avoid interference with their medication.
Ways to Enjoy Cooked Brussels Sprouts (List)
- Roasted: Toss with olive oil, salt, and pepper, then roast until crispy and caramelized.
- Sautéed: Pan-fry with garlic and bacon for a savory side dish.
- Steamed: Steam until tender and top with a sprinkle of lemon juice and herbs.
- Shredded in Salads: Lightly cook and then add to a warm salad with other greens.
