Mushrooms are a good source of plant-based protein, containing all nine essential amino acids (EAAs) usually found in meat. However, they are low in isoleucine, leucine, lysine, methionine and phenylalanine. This means that consuming mushrooms alone will not provide a complete protein profile. To compensate for this, mushrooms can be paired with foods such as carrots, hedge mustard seeds, chia seeds, pumpkin seeds, or spirulina. These combinations can create a complete protein profile, making mushrooms a viable option for those seeking plant-based protein sources.

Mushrooms are a good source of protein
However, mushrooms only provide 4 out of the 9 essential amino acids in adequate proportions. Amino acids are the building blocks of proteins, and there are 9 essential amino acids that our bodies cannot produce on their own. These 9 amino acids are considered "superstars", and a complete protein source contains all of them in roughly equal amounts. Mushrooms are deficient in isoleucine, leucine, lysine, methionine, and phenylalanine.
To compensate for this imbalance, mushrooms can be paired with complementary protein sources to create a complete protein meal. This concept is known as protein complementation. For example, a ratio of 0.8 cups of mushrooms to 2.7 carrots creates a complete protein profile, as carrots are rich in the amino acids that mushrooms lack. Similarly, chia seeds, pumpkin seeds, and spirulina can be combined with mushrooms in specific ratios to form complete proteins.
While mushrooms may not be a complete protein source on their own, they are still a valuable part of a balanced diet. They can be incorporated into various dishes to boost protein content and provide essential amino acids. Additionally, mushrooms are versatile and can be used as a meat substitute in vegetarian and vegan diets.

Mushrooms are incomplete proteins
Mushrooms are an excellent source of nutrients, including vitamins, minerals, and antioxidants. They are also low in calories and fat, making them a great addition to a healthy diet. Mushrooms do contain protein, but they are not considered a complete protein source. This is because they do not contain all nine essential amino acids that the body cannot produce on its own.
A complete protein source is one that contains all nine essential amino acids in roughly equal amounts. These amino acids are called "essential" because our bodies cannot produce them, and we need to obtain them from our diet. Mushrooms are a good source of four of these nine essential amino acids. However, they are lacking in isoleucine, leucine, lysine, methionine, and phenylalanine. To obtain adequate amounts of all nine essential amino acids from mushrooms alone, an average person would need to consume about 40 cups of mushrooms, which is not practical.
However, this does not mean that mushrooms cannot be a part of a complete protein meal. Mushrooms can be paired with other complementary protein sources to create a complete protein profile. For example, a ratio of 0.8 cups of mushrooms to 2.7 carrots creates a complete protein profile, as carrots are high in the amino acids that mushrooms lack. Similarly, chia seeds, pumpkin seeds, spirulina, and hedge mustard seeds can also be combined with mushrooms in specific ratios to form a complete protein profile.
While mushrooms may not be a complete protein source on their own, they are still a valuable part of a balanced diet. Their versatility and nutritional benefits make them a great addition to meat-based and plant-based meals alike, helping to boost the overall protein content of the dish.

Mushrooms can be paired with other foods to create complete proteins
Mushrooms are a good source of protein, offering 2.2 grams per cup. However, they are not considered a complete protein as they do not contain all nine essential amino acids. To form a complete protein, mushrooms can be paired with other foods that are rich in the amino acids they lack. This is known as protein complementation.
One food that mushrooms complement well is carrots. A ratio of 0.8 cups of mushrooms to 2.7 carrots creates a complete protein profile. This is because carrots are high in isoleucine, leucine, lysine, methionine, and phenylalanine, which mushrooms lack. Any ratio of more than 4:1 of carrot to mushroom will be complete.
Hedge mustard seeds are another good pairing with mushrooms. They are also high in the five amino acids that mushrooms lack. For every 2 cups of mushrooms, 0.3 cups of hedge mustard seeds are needed to form a complete protein. A ratio of more than 0.16:1 of hedge mustard seeds to mushrooms will be complete.
Chia seeds also complement mushrooms well. A ratio of 1.7 cups of mushrooms to 0.7 ounces of chia seeds creates a complete protein. This is because chia seeds are high in isoleucine, leucine, lysine, methionine, and phenylalanine. A ratio of more than 0.16:1 of chia seeds to mushrooms will result in a complete protein.
Pumpkin seeds are another good option to pair with mushrooms to create a complete protein. Pumpkin seeds are high in the five amino acids that mushrooms lack. A ratio of 1.7 cups of mushrooms to 0.3 cups of pumpkin seeds will result in a complete protein profile. A ratio of more than 0.15:1 of pumpkin seeds to mushrooms will be complete.
Other complementary protein sources that can be paired with mushrooms include beans, lentils, quinoa, tofu, and other legumes.
