Mushrooms are a source of protein, but are they high in protein? This is a tricky question. While mushrooms are not as protein-rich as meat, they contain high-quality protein that is easily absorbed by the body. This quality of protein is determined by its bioavailability, which refers to the rate and extent to which nutrients are absorbed, digested, and utilised by the body. Mushrooms, such as oyster, shiitake, and button mushrooms, are considered complete protein sources because they contain all nine essential amino acids required by the human body, although the concentrations are lower compared to animal sources. Furthermore, mushrooms provide additional nutrients like B vitamins, vitamin D, and beta-glucans, supporting the immune system and overall health. They are also low in calories, fat, and carbohydrates, making them a healthy, cholesterol-free alternative to animal proteins. However, meeting the recommended daily protein intake with mushrooms alone can be challenging, as it would require consuming large portions. Therefore, while mushrooms are a valuable source of protein, they are most beneficial when incorporated into a balanced diet alongside other protein sources.

What You'll Learn
Mushrooms are a good source of protein, but not a great source
Mushrooms, such as oyster, shiitake, and button mushrooms, are considered complete protein sources, meaning they contain all nine essential amino acids required by the human body. This includes amino acids like leucine and lysine, which are often deficient in plant proteins. However, the concentration of these amino acids in mushrooms is lower than in animal sources.
The quality of protein in mushrooms is high, and their bioavailability is impressive. Bioavailability refers to how efficiently the body can absorb, digest, and utilise the protein. Mushroom protein has a high bioavailability that rivals animal-based sources and surpasses plant-based sources like wheat and soybean. This means that while mushrooms may not provide a large quantity of protein, the protein they do contain is easily absorbed and used by the body for tissue growth, repair, and maintenance.
Additionally, mushrooms offer other nutritional benefits that contribute to their value as a protein source. They are low in calories, fat, and carbohydrates, making them suitable for a balanced diet. They also provide B vitamins, vitamin D, and beta-glucans, which support overall health and the immune system. Furthermore, mushrooms have antioxidant properties that can help reduce the risk of chronic diseases.
While mushrooms are a good source of protein, it would be challenging to meet recommended protein intakes with mushrooms alone. A varied diet that includes other protein sources alongside mushrooms is ideal. Mushrooms can be a valuable part of a balanced diet, offering high-quality protein and additional nutritional benefits.

They have a complete amino acid profile
Mushrooms are a source of plant protein, but they are not a good source of protein compared to meat products. They are often referred to as vegetables, but mushrooms are actually fungi. While the protein content of mushrooms is lower than that of meat, they contain high-quality protein that is easily absorbed by the body.
Mushrooms such as oyster mushrooms, shiitake mushrooms, and button mushrooms are considered complete protein sources because they contain all nine essential amino acids needed by the human body. These amino acids include leucine and lysine, which are often deficient in plant proteins. The amino acid content of mushrooms is comparable to that of an egg white, and their bioavailability surpasses that of wheat and soybean.
The quality of a protein is measured by its bioavailability, which refers to the extent and rate at which nutrients are absorbed, digested, and used by the body. Mushroom protein has a high bioavailability that rivals the quality of animal-based protein sources, unlike other plant-based foods like rice and wheat. A higher bioavailability means that the body utilizes proteins from mushrooms more efficiently for tissue growth, repair, and maintenance.
While it is possible to get mushroom protein from cooked mushrooms, it is not realistic to rely solely on mushrooms for protein. Mushroom supplements, which can be added to dishes like soups, smoothies, and sauces, are a convenient way to incorporate the nutritional benefits of mushrooms into your diet. Dried functional mushrooms tend to have a more concentrated protein content due to the removal of water, but it is important to adjust serving sizes accordingly.

They are low in calories, fat and carbs
Mushrooms are an excellent source of protein and other nutrients, but they are also low in calories, fat, and carbohydrates. This makes them a perfect addition to a balanced and light diet. For instance, three ounces of raw mushrooms, or about one cup, provide 1 to 2 grams of protein. They are also a good source of selenium and potassium.
Mushrooms are a cholesterol-free alternative to animal proteins, which can be high in saturated fat. They are also a great source of B vitamins, vitamin D, and beta-glucans, which support the immune system and contribute to overall health. In addition, their richness in antioxidants contributes to reducing the risk of chronic diseases such as cancer, cardiovascular diseases, and diabetes.
The protein in mushrooms is highly bioavailable, which means it is easily absorbed and used by the body for tissue growth, repair, and maintenance. This is in contrast to other plant-based proteins, which can be low in quality due to a lack of essential amino acids. Mushroom proteins usually have a complete essential amino acid profile, meeting dietary requirements.
While mushrooms are a good source of protein, it is important to note that they are not a significant source of protein compared to meat products. For example, if your recommended protein intake is 50 grams, you would need to consume at least 1,700 grams of fresh mushrooms to meet that intake. Therefore, it is ideal to incorporate other sources of protein into your diet rather than relying solely on mushrooms.
