How much iron is in a serving of chicken breast?

3 min read

While chicken breast is a powerhouse of lean protein, a 3.5-ounce serving of cooked, skinless chicken breast typically contains only about 1 milligram of iron, making it a modest rather than a rich source of this essential mineral. This amount can vary based on cooking method and portion size.

Quick Summary

A typical serving of chicken breast offers a small amount of highly absorbable heme iron. The article details the specific iron content, compares it with other food sources, and explains how to optimize its absorption.

Key Points

  • Modest Iron Source: A typical 3.5-ounce serving of cooked, skinless chicken breast contains approximately 1 milligram of iron.

  • Contains Heme Iron: The iron in chicken breast is heme iron, which is absorbed more easily by the body than the non-heme iron found in plants.

  • Dark Meat is Higher: Darker chicken meat, such as thighs, contains more iron than white meat chicken breast.

  • Absorption Can Be Boosted: Pairing chicken breast with vitamin C-rich foods, like broccoli or bell peppers, can increase iron absorption.

  • Less Iron Than Red Meat: Lean beef and liver are significantly richer sources of iron compared to chicken breast.

  • Important for Balanced Diet: Despite its modest iron content, chicken breast remains a healthy part of a varied diet that includes other iron-rich foods.

The Iron Content of Chicken Breast

When evaluating the iron content of chicken, it is important to distinguish between different cuts and preparations. Chicken breast is considered white meat, which contains less iron than the darker meat found in thighs and legs. The precise amount of iron can vary slightly depending on the size and preparation of the cut. For context, a 3.5-ounce (100g) serving of cooked, boneless, and skinless chicken breast contains roughly 0.9 to 1.1 milligrams of iron. A larger 6-ounce (170g) serving might contain approximately 0.83 milligrams, depending on the cooking method and exact cut.

Iron Content by Serving Size (Cooked, Skinless)

  • 3.5 ounces (100g): ~1.0 mg
  • 4 ounces: ~0.7 mg
  • 6 ounces (170g): ~0.83 mg

It is important to remember that this is a relatively small portion of the daily recommended iron intake, which ranges from 7 to 18 mg per day for the general population and up to 27 mg for pregnant women.

Chicken Breast Iron vs. Other Food Sources

The type of iron found in food plays a significant role in how well our bodies can absorb it. Animal-based foods, including chicken, contain heme iron, which is absorbed much more readily than the non-heme iron found in plant-based sources. While chicken breast is a source of this bioavailable heme iron, it is not the most concentrated source, even among meats.

How Heme and Non-Heme Iron Differ

  • Heme Iron: Found in animal products like meat, fish, and poultry. It is more efficiently absorbed by the body, with absorption rates of up to 40%.
  • Non-Heme Iron: Found in plant sources and fortified foods. Its absorption is influenced by other dietary factors and is generally less efficient. However, absorption can be increased by consuming non-heme iron with vitamin C-rich foods or a source of heme iron.

To put chicken breast's iron content into perspective, consider how it compares to other common foods. Red meat, such as lean beef, contains considerably more iron. Chicken liver, for example, is a significantly richer source of iron than chicken breast, containing around 11 mg per 100g. Plant-based sources like lentils and spinach can also offer a notable amount of non-heme iron.

Food Source (Cooked) Serving Size Approximate Iron Content (mg)
Chicken Breast (skinless) 3.5 oz (100g) ~1.0
Chicken Thigh (skinless) 3.5 oz (100g) ~1.3
Lean Beef 3.5 oz (100g) ~1.6
Beef Liver 3.5 oz (100g) ~5.2
Canned Clams 3 oz ~23.8
Lentils 1/2 cup ~3.5
Spinach (cooked) 1/2 cup ~3.0

Boosting Iron Absorption from Chicken

Since chicken breast offers a modest amount of iron, it is beneficial to optimize its absorption. The best way to do this is to pair it with foods rich in vitamin C.

Strategies for Maximum Absorption

  • Pair with Vitamin C: Serve chicken breast with a side of steamed broccoli, bell peppers, or a citrus-based dressing. The vitamin C helps the body capture and absorb the iron more efficiently.
  • Avoid Inhibitors: Certain substances can hinder iron absorption. It is best to avoid consuming coffee or tea during or immediately after an iron-rich meal, as their polyphenols can interfere with the process.
  • Be Mindful of Calcium: Calcium and iron compete for absorption, so if you are specifically trying to increase iron intake, consider eating calcium-rich foods like dairy products at a different time of day than your iron-rich meals.

Who Should Be Mindful of Their Iron Intake?

While chicken breast is a healthy part of a balanced diet, individuals with higher iron needs should be aware that it is not a primary source of this mineral. Populations at a higher risk of iron deficiency include pregnant women, children, and those with certain dietary restrictions. For these individuals, a focus on consuming a wider variety of iron-rich foods, including other cuts of chicken or lean red meat, can be beneficial. For those with specific concerns, consulting a healthcare professional or registered dietitian is always the best course of action.

Conclusion

In conclusion, a serving of chicken breast contains a small but valuable amount of heme iron. While it does not rival the iron content of red meat or liver, it remains a healthy and accessible source of bioavailable iron that contributes to overall mineral intake. By pairing chicken breast with vitamin C-rich foods and being mindful of absorption inhibitors, you can ensure that you are maximizing the nutritional benefits of your meal. Incorporating a variety of iron sources into your diet is the most effective strategy for maintaining optimal iron levels.

Frequently Asked Questions

According to nutritional data, a 100g (3.5-ounce) serving of cooked, skinless chicken breast contains around 0.9 to 1.1 milligrams of iron.

No, chicken breast is not considered a high-iron food. While it does contain iron in a form that is easily absorbed (heme iron), the overall quantity is modest, and it should not be relied upon as a primary source of the mineral.

Chicken thigh (dark meat) has more iron than chicken breast (white meat). A 100g serving of skinless chicken thigh contains approximately 1.3 milligrams of iron, compared to the breast's 1.0 milligram.

Red meat, such as lean beef, contains considerably more iron than chicken breast. For example, lean beef contains roughly 1.6 milligrams of iron per 100g, while chicken breast contains about 1.0 milligram.

Heme iron is a type of iron that is found exclusively in animal-based foods like meat, poultry, and fish. It is highly bioavailable, meaning the body can absorb it more efficiently than non-heme iron.

You can increase iron absorption by consuming chicken breast alongside foods rich in vitamin C, such as broccoli, tomatoes, or bell peppers. Vitamin C helps the body absorb non-heme iron more effectively and can also aid in the absorption of heme iron.

Cooking methods do not significantly alter the iron content of chicken breast. However, eating very dry cooked meat can make it harder to swallow, especially for young children.

To maximize iron absorption, avoid drinking coffee, tea, or excessive amounts of milk during an iron-rich meal. These contain compounds (polyphenols and calcium) that can inhibit iron absorption.
