Green plantains, a starchy tropical fruit, are a staple in many cuisines worldwide. Often confused with bananas due to their similar appearance, their nutritional profile and culinary uses differ significantly. For those tracking their iron intake, understanding how much iron is in green plantain is key to incorporating it into a balanced diet.
Iron Content in Raw vs. Cooked Green Plantain
The iron content of green plantains varies depending on whether it is raw or cooked. The form of iron found in plantains, like all plant-based foods, is non-heme iron. This form is less readily absorbed by the body compared to heme iron found in animal products. However, non-heme iron is still a valuable part of a healthy diet, and its absorption can be enhanced with certain nutritional pairings.
Raw Green Plantain Iron Content
According to data from USDA sources, a single raw green plantain weighing approximately 267g contains about 2.0 mg of iron. Another source states a 100g serving of raw plantain contains around 0.58mg of iron. This provides a moderate amount of the daily recommended intake and is a good base from which to start.
Cooked Green Plantain Iron Content
Cooking methods and heat can impact the nutritional composition of plantains, including their iron levels. For example, a 137g cup of boiled green plantains is reported to contain approximately 0.41 mg of iron. The lower figure in the cooked version could be attributed to a combination of smaller serving size compared to a whole raw plantain and the potential loss of water-soluble minerals during the boiling process.
Maximizing Non-Heme Iron Absorption
Since the iron in green plantains is non-heme, pairing it with other foods is crucial for optimal absorption. Here is how you can boost the iron you get from plantains:
- Pair with Vitamin C: Vitamin C is a powerful enhancer of non-heme iron absorption. Drizzling lime or lemon juice over a plantain dish, or serving it alongside vitamin C-rich vegetables like bell peppers or tomatoes, can significantly increase the iron your body absorbs.
- Include Heme Iron Sources: Eating plantains with sources of heme iron, such as meat, poultry, or fish, helps improve the absorption of the non-heme iron from the plantain.
- Soaking and Sprouting: For other high-phytate foods often eaten alongside plantains, like legumes and grains, soaking or sprouting can reduce phytate levels and increase iron bioavailability.
- Avoid Inhibitors: Certain compounds can inhibit iron absorption. These include calcium-rich foods (dairy) and polyphenols found in coffee and tea. It is best to consume these at least an hour before or after your plantain-based meal.
Green Plantain vs. Banana: Iron Comparison
While they are close relatives, green plantains and bananas have different nutritional profiles, especially when it comes to minerals like iron. The following table highlights some of the key differences:
| Nutrient (per 100g) | Raw Green Plantain | Raw Banana |
|---|---|---|
| Iron | ~0.58 mg | ~0.26 mg |
| Potassium | ~465 mg | ~358 mg |
| Vitamin C | ~11 mg | ~8.7 mg |
| Carbohydrates | ~31 g | ~23 g |
| Fiber | ~2.3 g | ~2.6 g |
As the table shows, green plantain contains a higher amount of iron per 100g compared to a typical raw banana. It also offers more potassium and Vitamin C, further distinguishing it as a nutrient-dense food with a strong role in a healthy diet.
Health Benefits of Dietary Iron
Iron is a vital mineral that is essential for many bodily functions. The iron found in foods like green plantains contributes to overall well-being in several ways.
Key functions of iron in the body:
- Hemoglobin Production: Iron is a crucial component of hemoglobin, the protein in red blood cells that transports oxygen from the lungs to the rest of the body.
- Energy and Growth: The body needs iron for physical growth, cellular function, and the synthesis of certain hormones.
- Immune System Support: Iron helps fortify the immune system, improving the body's ability to fight off infections.
- Cognitive Function: Adequate iron intake is linked to enhanced memory and improved cognitive function, while deficiency can lead to poor concentration.
Other Nutrients in Green Plantains
Beyond iron, green plantains are packed with other beneficial vitamins and minerals that contribute to their nutritional value. These include:
- Potassium: An electrolyte important for heart health and blood pressure regulation. Green plantains are notably high in potassium.
- Vitamin C: An antioxidant that supports the immune system and also aids in iron absorption.
- Magnesium: Important for muscle function and regulating blood sugar.
- Dietary Fiber: Promotes digestive health and can help manage blood sugar.

Conclusion
In summary, green plantains contain a modest, but valuable, amount of non-heme iron. While not an iron powerhouse on its own, its contribution to a balanced diet is significant, especially when prepared in a way that maximizes iron absorption. By combining green plantains with vitamin C-rich foods and being mindful of inhibitors, you can ensure your body makes the most of this nutritious tropical fruit. Its rich profile of other essential nutrients like potassium and vitamin C further solidify its place in a healthy eating plan.
