Cooking methods like grilling or sautéing retain iron
White button mushrooms are a valuable source of iron, containing about 0.3 mg per 100 grams or 1 cup of raw mushrooms. While this amount may seem modest, it can contribute significantly to your daily iron intake when combined with other iron-rich foods.
Cooking methods can significantly impact the iron content in mushrooms. Certain techniques, like boiling, may reduce nutrient retention, while grilling and sautéing are recommended for retaining iron. Steaming is another excellent option, as it maintains the moisture and prevents nutrient loss in mushrooms. The Maillard reaction, which occurs during frying or roasting, can also affect iron absorption, making it less accessible for absorption. Therefore, it is generally best to cook mushrooms over medium heat until they are tender to lock in important nutrients.
When preparing mushrooms, it is also beneficial to consider complementary foods that can enhance iron absorption. Consuming mushrooms with vitamin C-rich foods, such as bell peppers, tomatoes, or citrus fruits, can increase iron absorption. Additionally, eating foods rich in lysine, such as legumes and quinoa, may also promote iron absorption.
By incorporating grilled or sautéed white button mushrooms into your diet and pairing them with vitamin C-rich foods, you can effectively boost your iron intake and support your overall health.

Iron is essential for oxygen transport and overall health
White mushrooms, also known as table, common, button, or champignon mushrooms, are a popular variety of fungi. They have a mild flavor and smooth cap, making them a versatile ingredient in various dishes. But aside from their culinary uses, white mushrooms offer a host of nutritional benefits, including being a source of iron.
Iron is indeed essential for oxygen transport and overall health. It plays a critical role in the body's ability to transport oxygen and maintain healthy cells, skin, hair, and nails. Hemoglobin, a protein found in red blood cells, relies on iron to carry oxygen from the lungs to the rest of the body. A deficiency in iron can lead to symptoms such as low energy, breathlessness, headaches, irritability, dizziness, or anemia.
White button mushrooms contain approximately 0.3 mg of iron per 100 grams or about 0.3 milligrams per cup of raw mushrooms. While this amount is modest compared to other sources, it can still contribute to your daily iron intake when included in your diet. For instance, dried mushrooms have a higher iron content than fresh mushrooms due to the concentration of nutrients during the drying process.
To enhance the absorption of iron from white mushrooms, it is recommended to cook them using methods such as grilling or sautéing. Additionally, pairing mushrooms with vitamin C-rich foods can further increase iron absorption. Vitamin C helps prevent cardiovascular disease and has a recommended daily intake of around 75–90 mg. White mushrooms themselves contain approximately 1.47 mg of vitamin C per cup, making them a good source of this nutrient.
Incorporating white mushrooms into your diet not only supports your iron levels but also provides other health benefits. They are rich in glutathione and ergothioneine, which act as antioxidants and help eliminate potentially harmful substances from the body. White mushrooms also contain beta-glucan, a type of soluble fiber that has been linked to lowering blood cholesterol levels and reducing the risk of heart disease.
