However, their specific nutrient profiles differ, which influences their impact on your health.
A Closer Look at Broccoli’s Nutritional Value
Broccoli, with its distinctive tree-like appearance, is packed with vitamins C and K. It’s also a good source of folate, potassium, and fiber. Broccoli contains antioxidants like sulforaphane, which has been linked to various health benefits, including potential cancer prevention. A cup of chopped raw broccoli provides a decent amount of these essential nutrients, making it a valuable addition to any diet.
Unveiling the Goodness of Brussels Sprouts
Brussels sprouts, miniature cabbage-like buds, are similarly nutrient-dense. They are particularly rich in vitamin C and vitamin K, as well as folate and fiber. Brussels sprouts contain glucosinolates, compounds that, when broken down, can have anti-inflammatory and antioxidant effects. Like broccoli, Brussels sprouts offer a wealth of vitamins and minerals in a relatively small serving.
Iron Content: The Main Event
Now, let’s get to the heart of the matter: the iron content. While both broccoli and Brussels sprouts contribute to your daily iron intake, their levels differ slightly.
Quantifying Iron in Broccoli
Broccoli does contain iron, although it’s not as iron-rich as some other vegetables like spinach or lentils. A one-cup serving of chopped raw broccoli typically provides around 0.73 milligrams of iron. This amount contributes a small percentage to the recommended daily intake of iron, which varies depending on age, sex, and individual needs.
Measuring Iron in Brussels Sprouts
Brussels sprouts offer a slightly higher iron content compared to broccoli. A one-cup serving of raw Brussels sprouts boasts approximately 1.26 milligrams of iron. This difference, while seemingly small, can add up over time, especially if you consume Brussels sprouts regularly.
Comparing the Iron Density
While Brussels sprouts have a higher iron content per cup than broccoli, it’s crucial to consider the iron density – the amount of iron relative to the caloric content. Both vegetables are low in calories, making them nutrient-dense options. The slight edge in iron content per serving gives Brussels sprouts a slight advantage.
Bioavailability of Iron: Absorption Matters
The amount of iron present in food is only part of the story. Bioavailability, the extent to which your body can absorb and utilize the iron, is equally important. Iron from plant-based sources, known as non-heme iron, is generally less bioavailable than heme iron found in animal products.
Factors Influencing Iron Absorption
Several factors can influence the absorption of non-heme iron. Vitamin C enhances iron absorption, while compounds like phytates and tannins can inhibit it. The presence of vitamin C in both broccoli and Brussels sprouts helps to improve iron absorption.
Optimizing Iron Absorption from Broccoli and Brussels Sprouts
To maximize iron absorption from these vegetables, consider pairing them with other vitamin C-rich foods, such as citrus fruits or bell peppers. Avoid consuming them with foods or beverages high in phytates or tannins, like tea or coffee, at the same time. Cooking methods can also affect iron bioavailability.

Prioritize a balanced diet rich in diverse vegetables, fruits, and lean protein sources to optimize your overall health and well-being. It’s not about choosing one over the other but rather appreciating the unique contributions each brings to the table.
Which vegetable contains more iron, broccoli or Brussels sprouts?
Broccoli and Brussels sprouts both offer a decent amount of iron for vegetables, but Brussels sprouts typically contain slightly more iron per serving. A 1-cup serving of cooked Brussels sprouts usually provides a higher iron content compared to a 1-cup serving of cooked broccoli. However, the difference isn’t drastically large, so both vegetables can contribute to your daily iron intake.
While Brussels sprouts generally hold a slight edge in iron content, it’s important to consider the bioavailability of the iron. Non-heme iron, the type found in plant-based foods like broccoli and Brussels sprouts, is not as readily absorbed by the body as heme iron from animal sources. To enhance iron absorption from these vegetables, pair them with foods rich in vitamin C, which significantly improves non-heme iron uptake.
Are broccoli and Brussels sprouts good sources of iron for vegetarians and vegans?
Yes, broccoli and Brussels sprouts can be valuable sources of iron for vegetarians and vegans, particularly when incorporated into a well-balanced diet. As plant-based sources, they provide non-heme iron, which, while not as easily absorbed as heme iron from animal products, can still contribute significantly to meeting daily iron requirements.
