Comparing the Vitamin C Powerhouses
Broccoli and Brussels sprouts are both members of the cruciferous vegetable family and are celebrated for their impressive nutritional profiles. While many perceive citrus fruits as the primary source of vitamin C, these green giants often contain a comparable, if not higher, amount of the essential nutrient. However, when comparing these two, a detailed look at the data reveals subtle but important differences.
The Vitamin C Verdict: Raw vs. Cooked
The most significant factor in determining which vegetable has more vitamin C is its preparation. The ascorbic acid (vitamin C) found in these vegetables is water-soluble and heat-sensitive, meaning a large portion of it can be lost during the cooking process, especially when boiling.
- Raw Comparison: When consumed raw, broccoli typically edges out Brussels sprouts in terms of vitamin C content. According to data comparing raw nutritional values per 100 grams, raw broccoli contains about 89.2 mg of vitamin C, while raw Brussels sprouts offer around 85 mg. This is a very close race, and the exact content can vary based on growing conditions and freshness.
- Cooked Comparison: The impact of cooking can shift the balance. When comparing half-cup servings of cooked vegetables, the Office of Dietary Supplements notes that cooked broccoli has 51 mg of vitamin C, and cooked Brussels sprouts contain 48 mg. In general, steaming or microwaving are preferred methods for retaining vitamins compared to boiling, which can cause significant leaching.
Beyond Vitamin C: A Full Nutritional Comparison
While vitamin C is a key metric, a comprehensive nutrition diet should consider the full spectrum of nutrients. Both vegetables offer a wealth of health benefits that go far beyond just one vitamin.
Brussels sprouts, in particular, are noted for a higher concentration of certain vitamins and minerals. Per 100 grams, Brussels sprouts contain more Vitamin A, B1, B3, B6, and Vitamin D compared to broccoli. They also have more fiber, potassium, iron, and copper. Broccoli, on the other hand, contains higher levels of Vitamin B5 and calcium. Both are excellent sources of Vitamin K and folate.
Maximizing Vitamin C in Your Diet
To ensure you're getting the most vitamin C from these nutritional powerhouses, follow these tips:
- Eat Raw: When possible, incorporate raw broccoli into salads or as part of a crudités platter. Remember, the fresher the vegetable, the higher the vitamin C content.
- Steam Instead of Boil: If you prefer cooked vegetables, opt for steaming. Research has shown that steaming vegetables like broccoli can result in significantly less vitamin C loss (around 9–15%) compared to boiling (which can cause a 50% or more loss).
- Quick Cooking Methods: Other fast-cooking techniques like stir-frying or microwaving can also help preserve nutrients by minimizing exposure to high heat and water.
- Eat Soon After Prep: Vitamin C content can decline over time once vegetables are cut and exposed to air. For best results, cook or consume shortly after chopping.

The Broader Health Benefits
Beyond their vitamin C content, both broccoli and Brussels sprouts are packed with compounds that contribute to overall wellness. These include potent antioxidants, anti-inflammatory agents, and glucosinolates, which have been linked to potential anti-cancer properties. Regular consumption of these cruciferous vegetables is associated with numerous health advantages:
- Immune Support: The high vitamin C content, along with other vitamins and antioxidants, helps bolster the immune system.
- Antioxidant Effects: The antioxidants in both vegetables protect cells from damage caused by free radicals, which reduces oxidative stress and lowers the risk of chronic diseases.
- Heart Health: Both vegetables contribute to cardiovascular health by helping to lower cholesterol and maintain healthy blood pressure.
- Bone Health: The presence of vitamins C and K in both foods supports the formation of collagen and promotes overall bone density.
- Digestive Health: The rich fiber content aids in digestion and promotes a healthy gut microbiome.
Conclusion
So, do broccoli or Brussels sprouts have more vitamin C? When eaten raw, broccoli generally has a slight edge, but the difference is minimal and the final vitamin content largely depends on how the vegetables are prepared. When cooked, the difference can be even more negligible. Ultimately, focusing on which vegetable is 'better' for vitamin C is less important than incorporating both into your diet regularly. Both are exceptional sources of vitamin C and a wide array of other essential nutrients. Whether you prefer the large florets of broccoli or the mini cabbages of Brussels sprouts, you can be confident that you're making a healthy choice.

Nutritional Lists
Best Ways to Prepare for Vitamin C Retention
- Steaming: Use minimal water and a steamer basket to cook vegetables gently, preserving heat-sensitive vitamins like C.
- Microwaving: A quick cooking time with minimal water can prevent significant vitamin C loss.
- Stir-frying: Rapidly cooking vegetables in a pan with a small amount of oil is another effective method.
- Eating Raw: Adding chopped vegetables to salads or enjoying them as a crunchy snack is the best way to get the maximum vitamin C.
Foods That Complement Broccoli and Brussels Sprouts
- Garlic and Onions: These alliums enhance flavor and add their own health benefits.
- Olive Oil: Healthy fats aid in the absorption of fat-soluble vitamins.
- Lemon Juice: A squeeze of lemon adds flavor and its own vitamin C, while also potentially boosting iron absorption.
- Nuts and Seeds: Toasted nuts or seeds can add texture and healthy fats to roasted Brussels sprouts or broccoli.
Health Conditions Supported by a Diet Rich in These Veggies
- Cardiovascular Disease: The anti-inflammatory and antioxidant properties help lower risk.
- Certain Cancers: Compounds like glucosinolates have been linked to anti-cancer effects.
- Osteoporosis: Vitamins C and K support bone health.
- Poor Digestive Health: High fiber content promotes regularity and gut health.
Conclusion Revisited
In the final analysis, both broccoli and Brussels sprouts are champions of nutrition. The negligible difference in vitamin C should not be the deciding factor in your grocery shopping. Instead, consider which texture or flavor you prefer for a particular dish. The most important thing is to regularly consume a variety of colorful vegetables, utilizing cooking methods that preserve their high nutrient content. A diverse approach ensures you receive the broadest spectrum of vitamins, minerals, and phytonutrients for optimal health and wellness.
