Oyster mushrooms have twice as much iron as button mushrooms
Mushrooms are a great source of iron, a nutrient that is required for various bodily functions. Iron deficiency can cause breathlessness, low energy, anaemia, and dizziness. While not all mushrooms contain high amounts of iron, certain varieties do. Oyster mushrooms, or Pleurotus species, are a type of mushroom known for their impressive health-promoting properties. They have been used in traditional medicine for centuries and are loaded with fibre, vitamins, minerals, and other nutrients.
Oyster mushrooms are especially rich in iron. In fact, they contain up to twice as much iron as button mushrooms. This makes them an excellent choice for vegetarians and those following a meat-free diet, as they can help provide the recommended daily intake of iron, which is 1.2 mg per 100 grams for meat-eaters and 1.8 times higher for vegetarians.
Not only do oyster mushrooms have a high iron content, but they also provide other health benefits. Oyster mushrooms are a good source of fibre and protein and contain various vitamins and minerals, including vitamin D and selenium. They are also low in carbohydrates, making them suitable for low-carb diets.
Additionally, oyster mushrooms are known to promote heart health. Research suggests that consuming oyster mushrooms may help reduce heart disease risk factors such as high blood pressure and high cholesterol. A 2020 review of eight human studies found that oyster mushroom intake helped lower blood sugar, triglycerides, blood pressure, and insulin levels, all contributing to a decreased risk of heart disease.

Button mushrooms are a good source of iron for vegetarians and vegans
Iron is an essential nutrient required for various bodily functions. Iron deficiency can lead to several health issues, including breathlessness, low energy, dizziness, headaches, irritability, and anaemia. While iron from heme (meat) sources is better absorbed than non-heme (plant) sources, vegetarians and vegans can still obtain sufficient iron from plant-based foods.
Vegetarians and vegans can increase their iron intake by incorporating button mushrooms and other iron-rich plant foods into their diets. In addition to button mushrooms, good sources of iron include spinach, lentils, kidney beans, nuts, seeds, dark chocolate, and whole grains. Vitamin C-rich foods, such as tomatoes, can enhance iron absorption when consumed together with plant-based iron sources.
It is important to note that the recommended daily iron intake varies depending on age, sex, and individual needs. For most individuals, the daily value for iron is 18 mg, while pregnant women require a higher intake of 27 mg per day. By including button mushrooms and other plant-based iron sources in their diets, vegetarians and vegans can maintain adequate iron levels and support their overall health.

Shiitake mushrooms have higher iron levels than button mushrooms
Mushrooms are a great source of iron, a nutrient that is required for various bodily functions. While not all mushrooms contain high amounts of iron, certain varieties do. For example, oyster mushrooms contain twice as much iron as button mushrooms.
Shiitake mushrooms, in particular, have higher iron levels than button mushrooms. They contain 0.4 milligrams of iron per 100 grams. Although this amount may seem small, it is important to note that even vegetables with low iron content can play a significant role in your body's ability to absorb iron. Shiitake mushrooms are a good source of vitamin C, which assists in metabolizing iron from plant-based foods.
In addition to their iron content, shiitake mushrooms offer a range of other health benefits. They are the only natural plant source of vitamin D, which is essential for building strong bones. When exposed to UV light, shiitake mushrooms develop even higher levels of vitamin D. Regular consumption of these mushrooms may also boost heart health by lowering cholesterol and reducing inflammation.
Shiitake mushrooms are native to the mountain regions of Japan, Korea, and China, where they have been used for both food and traditional medicine for centuries. They have a rich, earthy flavor and a distinctive meaty taste. Today, they are the third most popular mushroom in the world and can be found fresh or dried in supermarkets, farmers' markets, and specialty grocers.
By including shiitake mushrooms in your diet, you not only benefit from their higher iron levels compared to button mushrooms but also gain access to a variety of other important nutrients and health benefits.
