Amino acids are organic compounds that form proteins, which are essential for several important functions in the body, including building muscle and repairing tissue. While animal-based foods generally contain all the necessary amino acids, plant-based proteins are usually low in one or more kinds. However, mushrooms are an exception, as they contain all nine types of essential amino acids. In addition, mushrooms are a good source of selenium, a powerful antioxidant that protects against heart disease and certain cancers.

| Amino acids in mushrooms | Amino acids are the building blocks of protein, and mushrooms contain all nine types of essential amino acids. |
| Number of amino acids | Mushrooms contain 17-20 different amino acids. |
| Types of amino acids | Examples of amino acids found in mushrooms include leucine, lysine, aspartic acid, glutamic acid, serine, glycine, alanine, cysteine, valine, methionine, phenylalanine, isoleucine, leucine, lysine, histidine, threonine, asparagine, glutamine, arginine, tyrosine, and tryptophan. |
| Amino acids and protein | Amino acids form chains that create proteins. Mushrooms have a higher protein content than most vegetables but significantly less than meat. |

What You'll Learn
Mushrooms contain all nine essential amino acids
Amino acids are organic compounds that form proteins, which are essential for many important bodily functions such as making hormones, building muscle, and repairing tissue. While our bodies can produce 11 of these amino acids, there are nine essential amino acids that we must obtain from food or supplements. Animal-based foods typically contain all nine essential amino acids, while plant-based proteins are often lacking in one or more of these amino acids.
Mushrooms are a notable exception, as they contain all nine essential amino acids. This makes them a valuable source of plant-based protein and an excellent addition to vegetarian and vegan diets. The protein content in mushrooms refers to dried mushrooms, not fresh ones, and ranges from 19-35%.
In addition to their high protein content, mushrooms also contain beneficial vitamins, minerals, and antioxidants. For example, shiitake mushrooms are a good source of niacin, vitamin B5, copper, and selenium, which has been linked to reducing the risk of heart disease and certain cancers. Mushrooms are also low in fat and calories, making them a nutritious and versatile ingredient in various dishes.
While mushrooms are a good source of protein and essential amino acids, they should not be considered a complete protein replacement. However, when combined with other plant-based proteins such as beans, soy, or nuts, mushrooms can help individuals on plant-based diets meet their daily protein requirements.

They are a good source of leucine and lysine
Mushrooms are a rich source of amino acids, with 13 wild edible mushroom species from Yunnan Province analysed and found to contain 20 free amino acids. These include leucine and lysine, which are both essential amino acids. Leucine is important for muscle protein synthesis and muscle growth, while lysine is important for protein synthesis, collagen formation, and immune function.
Leucine is one of the three branched-chain amino acids (BCAAs) that promote muscle growth and recovery, making it particularly important for athletes and those looking to build muscle mass. It stimulates muscle protein synthesis, which helps with muscle repair and growth. Leucine also helps to regulate blood sugar levels and promote weight loss by preserving muscle mass. Mushrooms are a good source of leucine, with 84mg per 100g of raw white button mushrooms.
Lysine is an essential amino acid that the body cannot produce on its own, so it must be obtained from food sources. It plays a crucial role in protein synthesis, collagen formation, and immune function. Lysine also helps prevent cold sores caused by the herpes simplex virus. Mushrooms are a good source of lysine, containing 107mg per 100g of product. This is particularly high when compared to the amount of lysine in raw white portobello mushrooms, which is described as low.
The presence of leucine and lysine in mushrooms makes them a valuable food source, especially for those who may not be consuming enough protein or other foods rich in these amino acids.

Amino acids give mushrooms their savoury taste
Amino acids are the building blocks of protein, and a valuable piece of mushroom nutrition. Mushrooms are a good source of protein, with popular edible species containing 19-35% protein. However, this protein content refers to dried mushrooms, not fresh ones.
The umami or savoury flavour of mushrooms is due to the presence of non-volatile compounds such as free amino acids and soluble sugars. These compounds interact on taste buds to create longer-lasting taste sensations. Mushrooms that contain naturally occurring glutamate, such as fresh mushrooms, are often combined with dried, rehydrated mushrooms that contain naturally occurring guanylate to create savoury dishes.
Amino acids are organic compounds that make up proteins in the body. There are 20 amino acids required for the body to function properly, and nine of these are essential amino acids that cannot be produced by the body and must be obtained from food. Mushrooms contain all nine types of these essential amino acids, including leucine and lysine, which are not found in many plant-based foods.
In addition to their savoury taste and high amino acid content, mushrooms also provide other benefits. They are a good source of protein for vegetarian and vegan diets, and can be used as a substitute for meat. They also contain vitamins, minerals, and antioxidants not found in meat.

Mushrooms are a good meat substitute
Secondly, mushrooms have a meaty texture, especially varieties like shiitake, oyster, and king oyster mushrooms. This makes them a great choice for vegan and vegetarian dishes, as they can provide a similar mouthfeel to meat. For example, oyster mushrooms can be breaded and fried until crisp, creating a vegan chicken filling for tacos or sandwiches. Shiitake mushrooms are also versatile and can be used in stir-fries, soups, dumplings, or egg rolls.
Thirdly, mushrooms are a nutritious option. While they may not be a one-to-one protein substitute for meat, they are a good source of anti-inflammatory antioxidants and can provide vitamin D if exposed to sunlight. They also contain all the essential amino acids, which are the building blocks of protein and are necessary for various bodily functions such as muscle growth and tissue repair.
Finally, choosing mushrooms as a meat alternative has environmental and ethical benefits. It reduces our reliance on animal farming, thereby decreasing environmental degradation and animal exploitation. This makes mushrooms a compassionate choice for those looking to minimise their ecological footprint without sacrificing flavour.
In conclusion, mushrooms make excellent meat substitutes due to their flavour, texture, nutritional profile, and environmental sustainability. They are a versatile and tasty option for those seeking to reduce their meat consumption or adopt a more plant-based diet.

They are rich in vitamins, minerals and antioxidants
Mushrooms are a good source of vitamins, minerals, and antioxidants, in addition to amino acids. They are prized for their medicinal properties and rich flavor and aroma. They are available year-round, both fresh and dried, and are widely cultivated. Their texture and savory flavor make them a suitable substitute for meat, and their low energy density can reduce the final dish's energy density.
Mushrooms are a good source of B vitamins, which help the body break down carbohydrates and fats and play an important role in the nervous system. They also contain selenium, a powerful antioxidant that protects against heart disease and some cancers. Shiitake mushrooms, in particular, contain eritadenine, a compound linked to helping the body remove cholesterol from the bloodstream. In one study, adding 90 grams of fresh shiitake to the diet daily lowered cholesterol by 12% in one week. Shiitake mushrooms also have antiviral and immunity-boosting properties.
Mushrooms are also a source of niacin, vitamin B5, copper, and selenium. They contain many essential minerals, including iron, phosphorous, copper, potassium, and selenium. One single portion of mushrooms can provide a quarter of the daily needs of selenium.
Mushrooms are a good source of protein, with popular species of edible mushrooms containing 19-35% protein. This refers to dried mushrooms, not fresh ones. While mushrooms have significantly less protein than meat, they have a higher protein content than most vegetables, making them very useful for people on plant-based diets. They are also rich in leucine and lysine, essential amino acids not found in many plant-based foods.
