Mushrooms contain all nine essential amino acids
Mushrooms are a rich source of protein, vitamins, and minerals and are low in calories and fat. They are also a good source of prebiotic fibres and vitamin D. In addition, mushrooms contain all nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are essential because the human body cannot produce them, and they must be obtained from food sources.
The presence of all nine essential amino acids in mushrooms makes them a valuable source of complete protein, especially for individuals following a plant-based or vegan diet. Plant proteins are often lacking in one or more essential amino acids, but mushrooms provide a complete amino acid profile that meets dietary requirements. This makes mushrooms a great alternative to traditional plant-based protein sources and a superior option for individuals with indigestion or malabsorption issues.
The amino acid content in mushrooms is comparable to that of animal-based protein sources, including protein powders, and even surpasses the amino acid scores of soybean and wheat according to WHO/FAO reference standards. Mushrooms have a high branched-chain amino acid (BCAA) composition, which is usually found in animal-based proteins. This makes mushroom-based proteins a suitable option for individuals who are allergic to or cannot consume whey, soy, or wheat-based proteins.
Additionally, mushrooms have been found to have high levels of ergothioneine (ERGO), an amino acid primarily produced by fungi. ERGO has been linked to fighting inflammation and oxidation, which are contributing factors to diseases associated with ageing, such as Parkinson's and Alzheimer's. The human body has a dedicated transport system for ERGO, distributing it throughout the body and accumulating it in tissues under oxidative stress. This further highlights the potential health benefits of including mushrooms in one's diet.

Edible mushrooms are a safe source of high-quality protein
Edible mushrooms are a safe and healthy source of high-quality protein. They contain all nine types of essential amino acids, which are usually lacking in plant-based proteins. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Mushrooms are also a good source of vitamins, minerals, and antioxidants, and are low in calories and fat.
The protein content of mushrooms is comparable to that of animal-based protein sources, including protein powders, and even surpasses that of soybeans and wheat. Mushrooms have a high branched-chain amino acid (BCAA) composition, which is usually only found in animal-based proteins. The amino acid profile of mushrooms is also similar to that of whey and soy isolates, making them a good option for those who are unable to consume whey or soy.
Mushroom proteins have been found to have various health benefits, including antimicrobial, antitumor, angiotensin-converting enzyme (ACE) inhibitory, and antiviral properties. They can also help to improve digestion and absorption, making them suitable for people with indigestion or malabsorption issues. Additionally, mushrooms are a good source of vitamin D, which is important for maintaining healthy bones and immune function.
Some specific types of mushrooms with high nutritional value include shiitake, reishi, and chaga mushrooms. Shiitake mushrooms, for example, contain eritadenine, a compound that helps remove cholesterol from the bloodstream. Reishi mushrooms have been used for centuries in Japan and China to promote healthy respiratory, digestive, circulatory, and cardiovascular systems, as well as for their anti-inflammatory and immune-boosting properties. Chaga mushrooms have been traditionally used for digestive aid, liver and heart health, and immune support.
Overall, edible mushrooms are a safe, nutritious, and high-quality source of protein that can be used as a meat alternative and offer various health benefits. They are a good option for those looking for plant-based sources of essential amino acids and proteins.

Amino acids in mushrooms are comparable to animal-based sources
Mushrooms are a good source of amino acids, containing all nine types of essential amino acids. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Mushrooms also contain branched-chain amino acids (BCAAs), which are usually only found in animal-based protein sources.
The quality of amino acids in mushrooms is comparable to animal-based sources. For example, shiitake mushrooms have a protein profile similar to that of whey and soy isolates, making them a viable option for therapeutic use. Additionally, the amino acid content in mushrooms is comparable to that of ovalbumin and surpasses soybean and wheat scores based on WHO/FAO reference standards.
Mushrooms have a complete essential amino acid profile, meeting dietary requirements, and can be used as a meat alternative. They are also easily digestible, making them a superior option for those with indigestion or malabsorption issues who may struggle with animal-based proteins.
Some specific types of mushrooms with high amino acid content include Pleurotus ostreatus, P. sajor-caju, and shiitake mushrooms. These mushrooms have been used for thousands of years in traditional medicine and are now recognized as safe sources of high-quality protein.
The amino acid ergothioneine, or ERGO, is made primarily by fungi and found in high concentrations in mushrooms. ERGO has been linked to fighting inflammation and oxidation, which contribute to diseases associated with aging, such as Parkinson's and Alzheimer's.

Amino acids in mushrooms can help fight inflammation and oxidation
Mushrooms are a source of nine essential amino acids that humans cannot synthesize on their own. These include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are found in oyster mushroom species, as well as other edible mushrooms.
Mushrooms are also a source of secondary metabolites, including ergothioneine (ERGO), an amino acid made primarily by fungi. ERGO has been shown to have potent antioxidant and anti-inflammatory properties, which may help fight inflammation and oxidation in the body. Research suggests that ERGO may be a useful tool in preventing age-related diseases such as Parkinson's and Alzheimer's, which are associated with inflammation and oxidation.
The human body has a dedicated transport system for ERGO, which distributes it throughout the body, including areas under oxidative stress. This further highlights the potential benefits of ERGO in preventing chronic diseases. While plants are the primary source of nutrients for humans, they rely on fungi in farm soils to obtain ERGO.
Cooking mushrooms can impact their amino acid profiles, with significant losses observed in protein amino acids when cooked. However, the specific cooking method and type of mushroom can make a difference. For example, the roasting and sautéing methods did not significantly impact the second-most limiting amino acid, histidine.
Overall, the amino acids present in mushrooms, particularly ERGO, show promising potential in fighting inflammation and oxidation, which contribute to various diseases and age-related conditions.
