The Calorie Count and Macronutrient Breakdown
For anyone monitoring their daily intake, knowing the specifics of vegetables like broccoli is crucial. The calorie count for broccoli varies slightly depending on whether it's raw or cooked, as cooking can affect its moisture content. A large, satisfying portion of 300g of cooked, boiled, and drained broccoli contains approximately 105 calories. This is based on the average of about 35 calories per 100g for cooked broccoli. The slight increase in calorie density per gram after cooking is because the vegetable loses some of its water, concentrating the nutrients and energy.
Macronutrient Profile for 300g of Cooked Broccoli
- Carbohydrates: Approximately 22g, with around 10g of dietary fiber and 4g of sugar. This high fiber content is a key reason broccoli is so filling, helping to control appetite.
- Protein: About 7g. While not a primary protein source, this amount contributes meaningfully to your daily total, especially for a plant-based food.
- Fat: A negligible 1g. Its virtually fat-free nature makes it an ideal food for low-fat diets.
A Micronutrient Powerhouse
Beyond its favorable calorie-to-volume ratio, cooked broccoli is a powerhouse of essential vitamins and minerals. These micronutrients play vital roles in everything from immune function to bone health.
Key Vitamins
- Vitamin C: A 300g portion delivers a staggering 195mg of Vitamin C, far exceeding the daily recommended value. This potent antioxidant is crucial for boosting the immune system, skin health, and iron absorption.
- Vitamin K: This portion also provides an impressive 423µg of Vitamin K, essential for blood clotting and bone health.
- Folate (Vitamin B9): With 324µg, it's an excellent source of folate, which is vital for cell growth and metabolism.
- Vitamin A: Offering 231µg, it supports eye health and immune function.
Essential Minerals
- Potassium: Around 879mg, helping to support healthy blood pressure.
- Iron: A good source, contributing to oxygen transport in the blood.
- Calcium: Provides bone-supporting calcium.
- Manganese: Important for metabolism and antioxidant defense.
Raw vs. Cooked: How Preparation Affects Nutrition
The most notable difference between raw and cooked broccoli is the change in water content, which affects the calorie density and, to a lesser extent, certain heat-sensitive vitamins. While 300g of cooked broccoli contains roughly 105 calories, the same weight of raw broccoli might be slightly less, around 102 calories. The difference is minimal for calorie counting, but it is worth noting that some nutrients, particularly Vitamin C, are slightly reduced by boiling, although steaming is an effective way to minimize nutrient loss.
| Nutrient Comparison (per 100g) | Raw Broccoli | Cooked Broccoli |
|---|---|---|
| Calories | 34 kcal | 35 kcal |
| Fiber | 3g | 3g |
| Vitamin C | 89mg | 65mg |
| Vitamin K | 102µg | 141µg |
| Potassium | 316mg | 293mg |
| Iron | 1mg | 1mg |
| Calcium | 47mg | 40mg |
