What You'll Learn
Mushrooms are a complete protein source
Edible mushrooms, such as oyster, shiitake, and button mushrooms, are particularly notable for their complete amino acid profile. While the protein content of mushrooms is lower than that of meat, their protein is easily absorbed by the body. For example, 100 grams of fresh mushrooms contain an average of 2.9 grams of protein, while chicken breast provides 32.1 grams in the same quantity.
The quality of a protein is determined by its bioavailability, or how efficiently the body can absorb, digest, and utilize it. Mushroom proteins have a high bioavailability comparable to animal-based sources and even surpass that of wheat and soybean. Additionally, mushrooms are a great source of fiber due to their carbohydrate structure, promoting a feeling of fullness.
Mushrooms also provide various health benefits beyond their protein content. They are rich in vitamins, minerals, and antioxidants, contributing to reduced risks of chronic illnesses such as cancer, cardiovascular diseases, and diabetes. Furthermore, mushrooms have antimicrobial, antiviral, and gut microbiota modulation properties.
While mushrooms are not the best plant-based source of protein, they stand out for their unique nutritional profile, offering a meaty texture and flavor that make them ideal meat substitutes in vegetarian and vegan diets. However, it is important to note that a solely mushroom-based protein diet is not realistic, and other protein sources should be incorporated for a balanced diet.

They have a high bioavailability
Mushrooms are a source of plant protein. While they are not a good source of protein compared to meat, they contain high-quality protein that is easily absorbed by the body. This is because mushroom proteins have a high bioavailability, which refers to the extent and rate at which nutrients are absorbed, digested, and used by the body. The high bioavailability of mushroom proteins means that the body can utilise them more efficiently for tissue growth, repair, and maintenance.
Studies on amanita mushrooms showed that their protein digestibility is very high. In addition, their amino acid content is comparable to that of egg whites, and their bioavailability surpasses that of wheat and soybean. This makes mushrooms a great alternative to animal-based protein sources, as they provide a complete essential amino acid profile that meets dietary requirements. Furthermore, mushroom proteins may provide health advantages by eliciting antioxidant, antitumor, angiotensin-converting enzyme (ACE) inhibitory, and antimicrobial properties.
While it is not realistic to rely solely on mushroom protein, they can be a convenient way to incorporate the health benefits and nutritional content of mushrooms into your diet. Mushroom supplements, for example, can be added to various dishes such as soups, smoothies, and sauces. Additionally, mushrooms are a good source of fibre due to their carbohydrate structure, which helps keep you full for longer. They also contain both simple and complex carbohydrates, which are beneficial to digestive health.
Some varieties of mushrooms offer a much bigger protein punch than others. For example, maitake mushrooms provide around 3g of protein per 100g fresh, while Portobello mushrooms offer a decent 2-2.5g per 100g fresh. Dried functional mushrooms tend to have a more concentrated protein content due to the removal of water weight, but it's important to adjust serving sizes accordingly.

They are a good meat substitute
Mushrooms are a good meat substitute, offering a meaty texture and an earthy flavour that can satisfy meat cravings. They are low in calories, fat, sodium and carbohydrates, making them perfect for a balanced and light diet.
While mushrooms are not packed with protein, they contain high-quality protein that is easily absorbed by the body. They are a complete protein source, meaning they contain all nine essential amino acids needed to boost human nutrition. The bioavailability of mushroom protein is comparable to animal-based protein sources and surpasses that of wheat and soybean.
Mushrooms are also a good source of vitamins and minerals, such as selenium, zinc, vitamin B1, B2, B5, B6, B12 and D. They are rich in antioxidants, which can reduce the risk of chronic diseases, and are a great source of fibre, which can aid digestive health and provide a longer-lasting feeling of fullness.
There are several types of mushrooms that make good meat substitutes, such as white button mushrooms, cremini mushrooms, portobello mushrooms, chicken of the woods, and king oyster mushrooms. These mushrooms can be used in a variety of dishes, including pasta sauce, pizza, stews, sandwiches, and tacos, to add flavour, texture, and nutrition.
However, it is important to note that mushrooms cannot provide the same amount of protein as meat. To match the protein content in a three-ounce serving of chicken, one would need to consume almost a pound and a half of mushrooms. Therefore, it is recommended to combine mushrooms with other plant-based protein sources, such as beans, tempeh, tofu, or seitan, to create a balanced meal.

They are environmentally sustainable
Mushrooms are a great source of protein, vitamins, minerals, and fiber. They are also environmentally sustainable.
Firstly, mushrooms are highly efficient at converting waste products into food. Unlike traditional crops, which require large amounts of land, water, and other resources to grow, mushrooms can be cultivated in a controlled indoor environment using waste products like sawdust, straw, and agricultural byproducts. This means that mushrooms can be grown using materials that would otherwise be discarded, reducing the amount of waste sent to landfills and minimizing the environmental impact associated with food production.
Secondly, mushrooms have a short growth cycle, with some varieties taking just a few weeks to mature. This allows them to be grown year-round, providing a consistent source of fresh, local food even in areas with harsh climates. Because they are grown indoors, mushrooms require fewer pesticides and herbicides than traditional crops, further reducing their environmental impact.
Thirdly, mushrooms are water-efficient. Mushroom growers use smart management and production practices that use less than 2 gallons of water to produce one pound of mushrooms. This is significantly less than the amount of water required to produce other fresh produce items. By controlling water usage and recycling water, mushroom growers minimize their impact on the surrounding environment.
Additionally, mushrooms are a low-energy footprint crop. Producing one pound of mushrooms takes 1.0 kilowatt-hour (kWh) of electricity, which is equivalent to the amount of energy it takes to run a coffeemaker for one hour each day. Mushrooms also have a low carbon footprint, with a serving of mushrooms emitting only 0.08 kg of CO2, which is lower than most other sources of protein and vegetables.
Finally, mushrooms can be used to remediate contaminated soil and water. Certain varieties of mushrooms have been shown to break down harmful chemicals and toxins, making them valuable tools in environmental cleanup efforts.
Overall, mushrooms are an environmentally sustainable food source that can help reduce our impact on the planet.
