What You'll Learn
Oyster mushrooms have twice as much iron as button mushrooms
Mushrooms are a great source of iron, especially for vegetarians, who need to consume 1.8 times more iron than meat-eaters. While not all varieties of mushrooms contain high amounts of iron, oyster mushrooms stand out in this regard.
Oyster mushrooms, or Pleurotus species, are a group of gilled mushrooms with around 40 types, including the commonly known American oyster mushroom (Pleurotus ostreatus or P. ostreatus). Oyster mushrooms have a complex, savoury flavour due to their high glutamic acid content, which is almost twice as much as that found in button mushrooms.
Oyster mushrooms are also known for their impressive health-promoting properties and are loaded with fibre, vitamins, minerals, and other important nutrients. Notably, they contain up to twice as much iron as button mushrooms. To put this into perspective, one cup of cooked white button mushrooms contains 2.7 mg of iron, while oyster mushrooms have twice as much, or 5.4 mg of iron per cup when cooked.
The high iron content of oyster mushrooms makes them an excellent choice for individuals looking to increase their iron intake. Iron is an essential nutrient required for various bodily functions, and its deficiency can lead to health issues such as breathlessness, low energy levels, anaemia, and dizziness. By incorporating oyster mushrooms into their diet, individuals can help ensure they are meeting their recommended iron intake and promote overall health and well-being.

Button mushrooms are a good source of iron
Iron is an essential mineral that plays a critical role in oxygen transport and energy production in the body. A deficiency in iron can lead to health issues like breathlessness, low energy, anaemia, and dizziness. While meat is a good source of iron, certain varieties of mushrooms also contain high amounts of iron.
Button mushrooms, the most commonly consumed type of mushroom, provide a modest amount of iron. They are touted for their ability to support iron absorption due to their vitamin C content, which enhances the bioavailability of iron. This makes button mushrooms a good source of iron, especially for those following a vegetarian or vegan diet, which can sometimes lack adequate iron sources.
White button mushrooms are also low in calories and high in other essential nutrients like vitamin D, selenium, potassium, and antioxidants. This nutrient profile makes them a versatile ingredient and a powerhouse for overall health. They can boost your immune system and provide a rich source of antioxidants.
While dried mushrooms have a higher iron content than fresh mushrooms, cooking fresh mushrooms can also increase the amount of iron available. This is because cooking breaks down cell walls, making more iron available to the body.
In addition to button mushrooms, other varieties of mushrooms that are good sources of iron include shiitake, oyster, and portobello mushrooms.

Shiitake mushrooms have higher iron levels than button mushrooms
Mushrooms are a great source of iron, with some varieties containing high amounts of the nutrient. While portabella and shiitake mushrooms are said to have very little iron, oyster mushrooms are known to contain twice as much iron as white button mushrooms.
White button mushrooms, also known as button mushrooms, are one of the most popular and widely available edible mushrooms. They are small, with white caps usually measuring 1 to 2 inches in diameter, and have a mild, earthy flavor and a delicate texture. They are commonly used in traditional dishes such as salads, pastas, and sauces, and can be enjoyed raw or cooked.
Shiitake mushrooms, on the other hand, are larger with caps ranging from 2 to 5 inches wide, and have a rich, earthy, and smoky flavor with a heartier texture. They are native to the mountain regions of Japan, Korea, and China, and have been used in East Asian cuisine and traditional medicine for centuries. Shiitake mushrooms are often used in Asian dishes such as stir-fries and soups, and are known to have a more intense flavor and texture compared to button mushrooms.
While button mushrooms are an excellent source of nutritional value, shiitake mushrooms are known to have an even higher nutrient content. In addition to being a good source of selenium and iron, shiitake mushrooms contain higher levels of vitamin D, zinc, and dietary fiber than button mushrooms. They also contain compounds such as eritadenine and beta-glucans, which provide additional health benefits such as lowering cholesterol and boosting immune health.
Therefore, while both button mushrooms and shiitake mushrooms offer nutritional benefits, shiitake mushrooms have higher iron levels and provide a greater variety of health benefits due to their higher nutrient content and unique compounds.

Portobello mushrooms are a significant source of iron
Portobello mushrooms are a good source of iron, containing 0.4 milligrams of iron per 100 grams. While this is not a significant amount compared to other vegetables, it can still contribute to your daily iron intake. Iron is an essential nutrient required for various bodily functions, and deficiency can lead to health issues such as breathlessness, low energy, anaemia, and dizziness.
Portobello mushrooms are a type of Agaricus bisporus, the most popular species of edible mushroom. They are grown commercially and are known for their meaty and savoury taste, making them a popular substitute for meat. In addition to their iron content, Portobello mushrooms offer various other nutritional benefits. They are low in fat, cholesterol-free, and contain essential vitamins and minerals.
Portobello mushrooms are an excellent source of B vitamins, including riboflavin, niacin, and pantothenic acid. These vitamins help boost energy levels, support brain function, and enhance red blood cell production, which aids in oxygen transport throughout the body. The mushrooms also contain dietary fibre, which promotes good heart health and supports a healthy gut microbiome by acting as a prebiotic for beneficial bacteria.
While Portobello mushrooms provide nutritional benefits, it is important to consume them in moderation to avoid any digestive discomfort. Some individuals may experience allergic reactions, including itching, swelling, or gastrointestinal distress. Additionally, the high potassium content in Portobello mushrooms can interfere with certain medications, so it is advisable for people on specific medications to consult their doctors before consuming these mushrooms regularly.
Overall, Portobello mushrooms are a significant source of iron and offer a range of additional nutritional benefits that can contribute to a balanced and healthy diet.

Dried mushrooms have more iron than fresh mushrooms
Mushrooms are a great source of iron, which is an essential mineral that plays a critical role in oxygen transport and energy production in the body. While not all varieties of mushrooms contain high amounts of iron, certain types do. For instance, white button mushrooms contain about 0.3 mg of iron per 100 grams, while shiitake mushrooms provide approximately 1.7 mg per cooked cup. Cremini mushrooms are particularly rich in iron, with around 2.1 mg of iron per 100 grams.
Oyster mushrooms, in particular, stand out for their impressive iron content. They contain up to twice as much iron as button mushrooms, making them an excellent choice for boosting iron intake.
Dried mushrooms have a higher iron content than fresh mushrooms. This is similar to how dried tomatoes have higher iron levels than fresh tomatoes. By removing the water content, the concentration of iron increases in dried mushrooms.
Cooking techniques can also affect the iron content in mushrooms. Boiling mushrooms may reduce their nutrient retention, while steaming or sautéing helps preserve more iron and other essential nutrients. Grilling is another recommended cooking method to retain iron content.
In addition to their iron content, mushrooms are a good source of protein, vitamins, minerals, and antioxidants. They offer various health benefits, including a potential reduction in the risk of certain cancers and diabetes when consumed as part of a nutritionally balanced diet.
It is worth noting that plant-based iron (non-heme iron) is more difficult for the human body to absorb than heme iron, which comes from animal sources. As a result, vegetarians and vegans may need to increase their iron intake to ensure adequate absorption. Pairing mushrooms with vitamin C-rich foods can enhance iron absorption.
