The Core Nutrients in 100g of Broccoli
A 100g portion of broccoli, which is roughly equivalent to a generous cup of chopped florets, is a nutritional powerhouse despite its low-calorie count. For reference, 100g is about the size of four average-sized broccoli pieces. The majority of broccoli's weight comes from its high water content, but the remaining nutrients are what make it a staple in healthy eating. Let's break down the key components of this serving.
Macronutrients
- Calories: 100g of raw broccoli contains approximately 34 calories, making it an excellent choice for weight management.
- Carbohydrates: The carbohydrate content is low, with around 6.6g per 100g. A significant portion of this is dietary fiber, leaving a very small amount of net carbs.
- Protein: This serving provides about 2.8g of protein, containing all essential amino acids.
- Fat: The fat content is almost negligible, typically less than 0.4g.
- Fiber: With about 2.6g of dietary fiber, a 100g serving promotes healthy digestion and satiety.
Micronutrients: A Rich Source of Vitamins
Broccoli truly shines in its vitamin content. A 100g serving of raw broccoli provides exceptional amounts of several key vitamins.
- Vitamin C: This portion can provide nearly 100% of the daily recommended intake of Vitamin C, a powerful antioxidant important for immune function and skin health.
- Vitamin K: A significant percentage of your daily Vitamin K needs are met, which is crucial for blood clotting and bone health.
- Folate (Vitamin B9): Folate is vital for cell growth and is particularly important for pregnant women. A 100g serving provides a solid amount of this essential nutrient.
- Vitamin A: Derived from beta-carotene, Vitamin A contributes to healthy vision and supports the immune system.
Minerals
Beyond vitamins, this vegetable also contributes a variety of important minerals to your diet.
- Potassium: Key for blood pressure regulation and overall heart health.
- Calcium: Contributes to strong bones and teeth.
- Iron: Important for oxygen transport in the blood.
- Manganese: A trace element involved in many bodily processes.
Cooking Methods: Raw vs. Cooked Broccoli (100g Portion)
The preparation method can influence the final nutritional content, particularly for water-soluble vitamins like Vitamin C. Here is a comparison of a 100g portion of raw versus cooked broccoli.
| Nutrient | Raw (100g) | Cooked, Boiled (100g) |
|---|---|---|
| Calories | ~34 kcal | ~28 kcal |
| Protein | ~2.8g | ~3g |
| Carbohydrates | ~6.6g | ~5g |
| Fiber | ~2.6g | ~3g |
| Vitamin C | ~89mg (99% DV) | ~40mg (45% DV) |
| Vitamin K | ~102mcg (85% DV) | ~88mcg (73% DV) |
| Potassium | ~316mg (7% DV) | ~142mg (3% DV) |
As the table illustrates, boiling can lead to a notable loss of water-soluble vitamins, though it may concentrate other nutrients. Steaming is often recommended as it preserves more of the heat-sensitive vitamins compared to boiling. However, even after being cooked, broccoli remains a highly nutritious food.
Health Benefits of a 100g Serving
Consuming even a modest portion of broccoli offers significant health advantages due to its dense nutrient profile and potent bioactive compounds.
- Supports Immune Function: The high vitamin C content acts as an antioxidant, strengthening the body's immune defenses.
- Reduces Inflammation: Bioactive compounds like sulforaphane have demonstrated strong anti-inflammatory properties.
- Promotes Gut Health: The dietary fiber aids in digestion, fosters healthy gut bacteria, and promotes bowel regularity.
- Aids Weight Management: The low-calorie count, high water content, and fiber promote satiety, helping to control appetite.
- Contributes to Heart Health: Fiber and antioxidant compounds can help regulate blood pressure and lower harmful cholesterol levels.
- Bone and Joint Support: Nutrients like calcium and vitamin K are essential for maintaining strong, healthy bones.
- Potential Anti-Cancer Properties: Broccoli contains compounds such as sulforaphane and indole-3-carbinol, which are linked to reducing the risk of certain cancers.
