Broccoli is a nutritional powerhouse, packed with a wide array of vitamins and minerals essential for health. Understanding the precise milligram (mg) content of a single cup can help in meal planning and tracking nutrient intake. The nutritional value can vary depending on whether the broccoli is consumed raw or cooked, with factors like water loss and heat sensitivity playing a role. Below, we provide a comprehensive breakdown of the milligrams found in a cup of broccoli, covering key micronutrients.
Nutrient Breakdown of Raw Broccoli
A standard cup of raw, chopped broccoli (approximately 91 grams) is rich in several key minerals and vitamins. Here is a closer look at the content in milligrams:
Vitamin C
One cup of raw broccoli offers approximately 81.2 mg of Vitamin C. This potent antioxidant is crucial for immune function, skin health, and tissue repair. The high concentration makes broccoli a more effective source of Vitamin C than many citrus fruits.
Potassium
Potassium, an electrolyte vital for blood pressure regulation and nerve function, is found in significant amounts in broccoli. A cup of raw broccoli contains around 287.6 mg of this mineral. The American Heart Association recommends increasing potassium intake, making broccoli a heart-healthy choice.
Calcium
While not as high in calcium as dairy products, broccoli provides a notable amount with excellent absorption due to its low oxalate content. A cup of raw broccoli contributes about 42.8 mg of calcium, supporting bone health.
Magnesium
Magnesium is another essential mineral present in broccoli, playing a role in muscle function and nerve health. You can expect to find approximately 19.1 mg of magnesium in a single cup of raw broccoli.
Phosphorus
For cell health and energy production, phosphorus is indispensable. A cup of raw broccoli provides about 60 mg of phosphorus. While many foods contain phosphorus, this contribution helps meet daily needs without excess.
Iron
Broccoli also contains a modest amount of iron, important for oxygen transport in the blood. A cup of raw broccoli has approximately 0.66 mg of iron. While this is a small amount, it is a valuable part of a balanced diet.
Sodium
For those watching their sodium intake, a cup of raw broccoli is an excellent choice, containing only about 30 mg.
Comparing Raw vs. Cooked Broccoli Nutrient Content
Preparation methods can impact the final milligram count of certain nutrients. Cooking, especially boiling, can cause water-soluble vitamins like Vitamin C to leach into the cooking water, but it can also increase the concentration of other nutrients by reducing water content. Steaming is often recommended for better nutrient retention.
Nutritional Comparison Table (Per 1 Cup, Chopped)
| Nutrient | Raw Broccoli (mg) | Boiled Broccoli (mg) | % Difference (Boiled vs. Raw) |
|---|---|---|---|
| Vitamin C | 81.2 mg | 50.6 mg | -37.7% |
| Potassium | 287.6 mg | 228.5 mg | -20.5% |
| Calcium | 42.8 mg | 31.2 mg | -27.1% |
| Magnesium | 19.1 mg | 16.4 mg | -14.1% |
| Phosphorus | 60.1 mg | 52.3 mg | -13.0% |
| Iron | 0.66 mg | 0.52 mg | -21.2% |
Note: The cooked values here refer to boiling without salt and draining. Different cooking methods and the addition of salt will alter these numbers.
Conclusion: Making Informed Nutritional Choices
Knowing the milligram content of different nutrients in broccoli allows for more strategic dietary planning. Raw broccoli generally retains more water-soluble vitamins, while the concentration of some minerals might change slightly with cooking due to water loss. Steaming is a gentle method that preserves most nutrients effectively. The important takeaway is that whether raw or cooked, broccoli remains a nutrient-dense food packed with beneficial compounds.
