1. Understanding the Nutritional Profile of Mushrooms
Mushrooms have long been celebrated for their unique flavor and culinary versatility, but their nutritional value often goes unnoticed. Let’s delve into the impressive nutritional profile of mushrooms and discover why they are considered a protein-rich food source.
1.1. What is the Protein Content in Mushrooms?
The protein content in mushrooms can vary depending on the species, growing conditions, and maturity stage. However, on average, mushrooms contain a substantial amount of protein, making them a valuable addition to a balanced diet.
| Mushroom Type | Protein Content (per 100g dry weight) |
|---|---|
| Shiitake | 14.87 – 27.13g |
| Oyster | 18 – 19.15g |
| White Button | 26.60 – 39.84g |
| Portobello | ~30g |
| Lentinus squarrosulus | 30.12g |

The nutritional value of mushroom protein lies not only in its quantity but also in its ability to meet dietary requirements; recommended dietary allowance (RDA) and protein efficiency ratio (PER).
1.2. What Other Nutrients Can Be Found in Mushrooms?
Beyond protein, mushrooms are packed with essential nutrients that contribute to overall health and well-being:
- Vitamins: Mushrooms are a good source of B vitamins, including riboflavin, niacin, and pantothenic acid, which play crucial roles in energy production and nerve function.
- Minerals: They contain important minerals like selenium, potassium, copper, and iron, which are essential for various physiological processes, including immune function and red blood cell formation.
- Fiber: Mushrooms are a good source of dietary fiber, which promotes digestive health and helps regulate blood sugar levels.
- Antioxidants: Mushrooms are rich in antioxidants like ergothioneine and glutathione, which help protect cells from damage caused by free radicals.
- Low in Calories and Fat: Mushrooms are naturally low in calories and fat, making them a healthy choice for weight management and heart health.
2. Exploring the Protein Quality of Mushrooms
While the quantity of protein in mushrooms is noteworthy, the quality of the protein is equally important. Let’s explore the amino acid profile of mushroom protein and its digestibility.
2.1. Do Mushrooms Contain All Essential Amino Acids?
Yes, mushrooms generally contain all nine essential amino acids, which are the building blocks of protein that the body cannot produce on its own. These amino acids are crucial for muscle growth, tissue repair, and various other bodily functions.
- Isoleucine
- Leucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
- Histidine
The Essential Amino Acid Score (EAAS), also known as the chemical score, compares the proportion of each essential amino acid in a test protein to a reference standard that contains all of the essential amino acids in the appropriate quantities to meet the demands, according to the WHO/FAO/UNU reference.
2.2. How Digestible is Mushroom Protein?
The digestibility of mushroom protein is influenced by factors such as the presence of chitin, a complex carbohydrate found in the cell walls of mushrooms. However, cooking and processing methods can improve the digestibility of mushroom protein.
- Cooking: Cooking mushrooms helps break down chitin and softens their tissues, making the protein more accessible for digestion.
- Processing: Techniques such as grinding, fermenting, or extracting protein concentrates can further enhance the digestibility of mushroom protein.
Protein Digestibility Corrected Amino Acid Score (PDCAAS) is one of the earliest methods the Food and Agriculture Organization and the World Health Organization devised to evaluate protein quality. PDCAAS values for mushrooms ranged from 0.35 to 0.70 based on in vitro and in vivo digestibility studies. Biological Value (BV) of protein is the percentage of amino acids ingested by the intestines that the body retains. The BV score of mushrooms (80) is at par with milk (100) and meat (80–85), and higher than cereal (40–45) and legume (50–55).
