Mushrooms are a source of protein, but how much protein do they contain, and how does this compare to other foods? Mushrooms are often used as meat substitutes, and they do contain all nine essential amino acids. However, their protein content is lower than that of meat. For example, 100g of fresh mushrooms contain 2.9g of protein, while chicken breast contains 32.1g of protein in 100g. Mushrooms also contain vitamins, minerals, antioxidants, and fibre, and they are low in calories, fat, and carbohydrates. They are a good source of B vitamins, including thiamine, riboflavin, B6, and B12. While mushrooms are not a complete source of protein on their own, they can be a valuable part of a balanced diet.
| Characteristics | Values |

| Are mushrooms a source of protein? | Yes, raw mushrooms contain protein, vitamins, minerals, and fiber. |
| How much protein do mushrooms contain? | Around 100 g of fresh mushrooms contain an average of 2.9 g of protein. |
| How does this compare to animal proteins? | Animal proteins are generally considered complete proteins as they contain all nine essential amino acids, but their production is incredibly expensive and has a significant environmental impact. Mushroom proteins are high-quality, low-cost, widely available, and meet environmental and social requirements, making them a suitable alternative. |
| Which mushrooms have the highest protein content? | Morel mushrooms have the highest protein content when fresh, while oyster mushrooms have the highest fresh and dried protein content compared to other functional mushrooms. Dried mushrooms tend to have a more concentrated protein content than fresh mushrooms due to the removal of water weight. |
| How much protein would you need to consume from mushrooms to meet the recommended daily intake? | If your recommended protein intake is 50 g, you would need to eat at least 1700 g of fresh mushrooms or take 167 g of dried mushroom powder. Therefore, it is ideal to incorporate other sources of protein into your diet rather than relying solely on mushrooms. |
| Are there any additional benefits of mushroom protein? | Mushroom proteins have a high bioavailability, meaning the body utilizes them more efficiently for tissue growth, repair, and maintenance. They also have antioxidant, antitumor, angiotensin-converting enzyme (ACE) inhibitory, antimicrobial, antiviral, and gut microbiota modulation properties. |

What You'll Learn
Mushrooms are a complete protein source
Edible mushrooms, such as oyster, shiitake, and button mushrooms, are considered complete protein sources. For instance, maitake mushrooms provide around 3g of protein per 100g, while the protein content of portobello mushrooms is slightly lower, ranging from 2 to 2.5g per 100g. Dried mushrooms tend to have a higher protein concentration due to the removal of water, but it's important to adjust serving sizes accordingly.
Mushrooms are an excellent alternative to animal proteins, as they are low in cost, widely available, and environmentally sustainable. They also offer additional health benefits, including antioxidants, vitamins, minerals, and fiber. The bioavailability of mushroom protein is high, surpassing that of wheat and soybean. This means the body can efficiently utilize the protein for tissue growth, repair, and maintenance.
However, it is important to note that meeting the recommended daily protein intake with mushrooms alone can be challenging. While mushrooms are a good source of protein, they should ideally be combined with other protein sources to ensure a balanced diet.
Incorporating mushrooms into your meals can be done in various ways. They can be cooked and added to stir-fries, soups, or salads, providing a meaty texture and flavor to plant-based dishes. Additionally, mushroom supplements are a convenient option, allowing you to add mushroom powder to various dishes or even your morning coffee.

They are low in protein compared to meat
Mushrooms are a source of protein, but their protein content is lower than that of meat. For example, 100 grams of chicken breast contains 32.1 grams of protein, while 100 grams of fresh mushrooms contain only 2.9 grams. Even duck, the meat with the lowest protein content among common choices, has over 18 times more protein than the same weight of the most protein-rich mushrooms.
While mushrooms are not a good source of protein compared to meat, they are a complete protein source, containing all nine essential amino acids needed by the human body. These include leucine and lysine, which are often deficient in plant proteins. The amino acid profile of mushrooms is, in fact, more complete than that of meat. The bioavailability of mushroom protein is also high, surpassing that of wheat and soybean, and comparable to egg whites. This means that the body can efficiently utilize the protein from mushrooms for tissue growth, repair, and maintenance.
In addition to their protein content, mushrooms provide other essential nutrients such as B vitamins, vitamin D, and beta-glucans, which support the immune system and overall health. They are also a source of antioxidants, which can help reduce the risk of chronic diseases such as cancer, cardiovascular disease, and diabetes. Mushrooms are low in calories, fat, and carbohydrates, making them suitable for a balanced and light diet.
Despite their lower protein content, mushrooms can be a viable alternative to meat due to their meaty texture and flavor, especially in vegetarian and vegan diets. However, it is important to note that a solely mushroom-based protein diet is not realistic, and it is best to incorporate other sources of protein for a balanced diet.

Oyster mushrooms have a high protein concentration
Mushrooms are a great source of protein and offer a wide range of health benefits. They are rich in vitamins, minerals, fibre, and bioactive compounds, making them a valuable part of our diet. Oyster mushrooms, in particular, stand out for their high protein concentration.
Oyster mushrooms, or Pleurotus ostreatus, are a group of gilled mushrooms that contain powerful plant compounds. They are a popular type of mushroom linked to several health benefits. In addition to being highly nutritious, they may promote heart and immune system health, encourage healthy blood sugar control, and provide antioxidant and anti-inflammatory effects.
Oyster mushrooms contain the highest fresh and dried protein content compared to other functional mushrooms. They are a good source of niacin, fibre, and riboflavin. One cup of raw, sliced oyster mushrooms (approximately 86 grams) provides 28 calories, with 32% coming from protein. This amounts to 2.9 grams of protein, which is quite low compared to animal-based proteins but high compared to other mushroom varieties.
The protein in oyster mushrooms is also of high quality and has a high bioavailability. Oyster mushrooms are a complete protein source, meaning they contain all nine essential amino acids needed by the human body. This includes leucine and lysine, which are often deficient in plant proteins. The amino acids in oyster mushrooms are comparable in quality to those in egg whites, surpassing wheat and soybean.
