Which is Higher in Iron, Broccoli or Brussels Sprouts?

3 min read

One cup of cooked brussels sprouts offers significantly more iron than the same serving size of cooked broccoli. While both are nutritious cruciferous vegetables, their iron content differs, a key detail for those tracking their mineral intake. This article compares the iron levels in broccoli and brussels sprouts and offers strategies to maximize the iron you absorb from your food.

Quick Summary

A comparison of the iron content in broccoli and brussels sprouts reveals that brussels sprouts are the richer source per cup. Understanding the type of iron in these vegetables and pairing them with vitamin C can significantly enhance absorption. Explore the nutritional differences and preparation methods.

Key Points

  • Iron Content: Brussels sprouts contain nearly double the amount of iron per cooked cup compared to broccoli.

  • Absorption Aid: The iron in both vegetables is non-heme, but pairing them with vitamin C-rich foods significantly boosts absorption.

  • Rich in Vitamin C: Broccoli and brussels sprouts are both excellent sources of vitamin C, an essential component for iron uptake.

  • Complementary Nutrients: While brussels sprouts lead in iron, broccoli offers other beneficial compounds like sulforaphane and antioxidants.

  • Cooking Method: Steaming or roasting is recommended to retain nutrients, while cooking in a cast-iron pan can also increase iron.

  • Overall Winner: For maximum iron intake from a single serving, brussels sprouts are the better option, but both are highly nutritious.

Comparing Iron Content in Broccoli and Brussels Sprouts

For individuals focused on boosting their dietary iron, especially from plant-based sources, knowing which foods provide the most can be invaluable. When comparing two popular cruciferous vegetables, broccoli and brussels sprouts, the numbers show a clear winner in the iron category.

According to data from reliable nutritional databases, one cup of cooked brussels sprouts contains approximately 1.8 mg of iron. In contrast, one cup of cooked broccoli provides about 1 mg of iron. This means that brussels sprouts offer nearly double the iron of broccoli per cooked cup, making them the superior choice for this particular mineral.

It's important to note that the iron in both vegetables is non-heme iron, which is less readily absorbed by the body than the heme iron found in meat and other animal products. However, this does not mean that plant-based iron sources are ineffective; with the right preparation and food pairings, you can significantly enhance your body's ability to absorb this vital mineral.

Nutritional Profiles Beyond Iron

While the main focus here is on iron, it is worth examining the broader nutritional differences between these two vegetables. Both are nutritional powerhouses, offering a wealth of vitamins and other health benefits.

  • Brussels Sprouts: These are excellent sources of Vitamin K, essential for blood clotting and bone health, and a very good source of Vitamin C, which is crucial for immune function and iron absorption. They also contain high levels of folate, potassium, and dietary fiber.
  • Broccoli: Broccoli is also rich in Vitamin C, often exceeding the daily requirement in a single serving. It provides a good dose of Vitamin K and folate, along with a decent amount of potassium and dietary fiber. Broccoli is particularly well-known for its antioxidants and beneficial plant compounds.

How to Maximize Iron Absorption

Since the iron in both broccoli and brussels sprouts is non-heme, following these tips can help ensure your body gets the most from these nutritious vegetables:

  1. Pair with Vitamin C: Consume your broccoli or brussels sprouts with a source of vitamin C. This dramatically increases the absorption of non-heme iron. Examples include squeezing lemon juice over roasted sprouts or serving broccoli with tomatoes or bell peppers.
  2. Avoid Inhibitors: Certain compounds can hinder iron absorption. Tannins found in tea and coffee and phytates in some grains can reduce bioavailability. Try to consume these beverages separately from your iron-rich meals.
  3. Cooking Matters: While some iron can be lost during boiling, light steaming or roasting can help retain more nutrients. Cooking in a cast-iron skillet can also slightly increase the iron content of your food.

Broccoli vs. Brussels Sprouts: Nutritional Comparison Table

Nutrient (per 1 cup, cooked) Broccoli Brussels Sprouts
Iron (mg) ~1.0 mg ~1.8-1.9 mg
Vitamin C (% DV) 112% 107%
Vitamin K (% DV) N/A (high) High
Folate (% DV) 15% High
Fiber (g) ~2.5-5.1 g ~4.1-6.4 g
Protein (g) ~2.4 g ~4.0 g

Note: Nutritional values can vary based on preparation method and serving size. The values represent approximate averages based on cooked portions.

Conclusion

Based on a direct comparison, brussels sprouts are higher in iron than broccoli per cup when cooked. While this makes brussels sprouts the winner in this specific nutritional battle, both vegetables are excellent additions to a healthy diet. Broccoli offers slightly more vitamin C per serving, which enhances the absorption of the non-heme iron found in both. For those seeking to maximize their iron intake, a diet incorporating both vegetables and utilizing strategies like pairing with other vitamin C-rich foods and mindful cooking is the best approach. Ultimately, both offer distinct and valuable benefits that support overall health and well-being.

Frequently Asked Questions

Brussels sprouts contain significantly more iron per serving than broccoli. A cup of cooked brussels sprouts provides approximately 1.8 to 1.9 mg of iron, whereas a cup of cooked broccoli provides about 1 mg.

To improve non-heme iron absorption, pair these vegetables with a food rich in vitamin C, such as bell peppers, tomatoes, or a splash of lemon juice. You can also try cooking them in a cast-iron pan.

No, the iron in these vegetables is non-heme iron, which is less easily absorbed by the body than the heme iron found in meat and other animal products.

Brussels sprouts are rich in other nutrients, including Vitamin K, Vitamin C, folate, potassium, and dietary fiber.

Yes, excessive boiling can leach some of the nutrients, including minerals, into the water. For best nutrient retention, it is recommended to steam, roast, or stir-fry these vegetables.

To maximize iron absorption, it is best to avoid consuming tea and coffee with your meal, as their tannins can inhibit absorption. Additionally, certain compounds in grains can also have a minor effect.

Both vegetables are extremely healthy and offer a wide range of benefits. The 'healthier' option depends on your specific nutritional needs. Brussels sprouts offer more iron, while broccoli provides similar levels of vitamin C and unique antioxidant properties.
