Mushrooms are a good source of protein, vitamins, minerals, and antioxidants. They are classified as vegetables but are technically part of the kingdom Fungi. Mushrooms have a very distinct umami flavour and a meaty texture when cooked, making them a popular meat substitute in plant-based meals. However, they are not a good source of protein compared to meat products. Each variety of mushroom has a unique nutrient profile, so its protein content can vary based on type. For instance, oyster, shiitake, and button mushrooms are considered complete protein sources because they contain all nine essential amino acids. On the other hand, some mushrooms contain toxins and are toxic to humans.
| Characteristics | Values |
|---|---|
| Nutritional value | Mushrooms are a source of antioxidants, vitamins, minerals, and fibre. They are low in calories, fat, sodium, and cholesterol. |
| Protein content | Mushrooms are a source of protein, but not a good source. They contain between 1.4 and 2.8 grams of protein per cup, or 1-2% of the daily value per 100 grams. |
| Amino acids | Mushrooms contain all nine essential amino acids, making them a complete protein source. |
| Health benefits | Mushrooms are said to have medicinal properties, including the ability to counteract inflammation, fight viruses and bacteria, and lower cholesterol and blood sugar. They are also being studied for their potential cognitive benefits. |
| Environmental impact | Mushroom farming is less resource-intensive than meat production, which occupies about one-third of the Earth's land and contributes to greenhouse gas emissions. |
| Culinary uses | Mushrooms can be cooked in a variety of ways, including grilling, baking, broiling, sautéing, and roasting. They are versatile and can be used in sauces, stews, soups, grain dishes, and more. |

What You'll Learn

Mushrooms are a source of protein
Mushrooms are classified as vegetables, but they are technically not plants; they are part of the kingdom Fungi. They are low in calories, have virtually no fat or cholesterol, and are very low in sodium. Mushrooms are also a good source of selenium, potassium, copper, phosphorus, zinc, and B-complex vitamins like riboflavin (B2), niacin (B3), pantothenic acid (B5), and thiamine.
Because of their protein content, mushrooms are a popular alternative to meat for vegans and vegetarians. They have a very meaty flavor and texture when cooked, making them a great substitute in various plant-based meals. However, it is important to note that mushrooms should not be considered the only source of protein in a balanced diet, as they only provide moderate amounts of protein.
Mushrooms are also known for their medicinal properties. They contain compounds that can counteract inflammation, fight viruses and bacteria, and lower cholesterol and blood sugar. Additionally, they have been found to have high levels of antioxidant compounds, which can benefit health.

They are not a complete protein source
Mushrooms are a source of plant protein, but not a good source. They are neither plants nor animals but belong to the kingdom Fungi. Mushrooms have a very meaty flavour and texture when cooked, but their protein content is lower than that of meat.
Each variety of mushroom has a unique nutrient profile, so their protein content can vary based on type. Mushrooms only have 1 to 2 percent of your daily value (DV) for protein per 100 grams (3.5 ounces), according to the USDA. This is less than protein-rich vegetables like lima beans, green peas, spinach, asparagus and artichokes.
Even duck, the meat with the lowest protein per 100 grams, is over 18 times higher in protein than the same weight of mushrooms with the most protein. If you rely on mushrooms to meet your daily value for protein, you would have to eat more than 55 ounces or 18 cups. Eating too many mushrooms could have risks and lead to excessive consumption of other nutrients.
Mushrooms are a good source of minerals like copper, phosphorus, zinc, and B-complex vitamins like riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), and selenium and potassium. They are also a good source of fibre, particularly the soluble fibre beta-glucan.
While mushrooms are a source of protein, they are not a complete protein source on their own and must be combined with other protein sources to constitute a complete diet.

They are a good meat substitute
Mushrooms are a good meat substitute, especially for those who want to reduce their meat consumption for health, environmental, or ethical reasons. While they are not a significant source of protein, mushrooms offer a range of nutritional benefits and can provide a satisfying umami flavour to dishes.
Mushrooms are classified as vegetables, but they are technically part of the fungi kingdom. They are low in calories, fat, cholesterol, and sodium, and provide vitamins and minerals, including selenium, zinc, potassium, and B vitamins such as riboflavin and niacin. Some mushrooms, like Lion's Mane, are also being studied for their potential brain health benefits. Mushrooms are one of the few natural sources of vitamin D, especially when exposed to sunlight or light. They are also a source of antioxidants and can provide anti-inflammatory benefits.
In terms of substituting meat in dishes, mushrooms are versatile and can be used in a variety of recipes. They can be sliced, shredded, or ground, and work well in sauces, stews, pizzas, sandwiches, and more. King oyster mushrooms, for example, can be sliced and seared like scallops, or shredded and used like crab meat. White button mushrooms, cremini, and portobello mushrooms are good at absorbing flavours and can be used in place of beef or other meats in pasta sauces, stews, and on pizzas. Chicken of the woods mushrooms can be cooked with chicken seasonings to create a chicken-like flavour and texture, making them ideal for substituting chicken in recipes.
While mushrooms may not provide the same level of protein as meat, they can be combined with other plant-based protein sources like beans, tempeh, tofu, or seitan to create a balanced meal. This allows individuals to reduce their meat consumption while still maintaining a satisfying and flavourful dish.
Overall, mushrooms are a tasty, nutritious, and sustainable alternative to meat, making them a good option for those looking to explore meat-free options.

They are rich in vitamins and minerals
Mushrooms are a rich source of vitamins and minerals. They are a good source of B vitamins, including thiamine, riboflavin, B6, and B12. They also contain vitamin D, which is important for bone and immune health. In fact, mushrooms are the only vegan, non-fortified dietary source of vitamin D.
Mushrooms are also a good source of minerals such as selenium and potassium. Selenium helps to prevent cell damage in our bodies, while potassium is known for reducing the negative impact of sodium on the body and lessening the tension in blood vessels, which can help lower blood pressure. Cremini mushrooms are an excellent source of zinc, which is important for the immune system and for ensuring optimal growth in infants and children.
Mushrooms also contain antioxidants, which can help to protect against serious health conditions such as Alzheimer's, heart disease, cancer, and diabetes. The anti-inflammatory effects of mushrooms have been shown to improve the efficiency of the immune system. Additionally, mushrooms are a source of indigestible carbohydrates called chitin, which contributes "bulk" to our diet.
While mushrooms are classified as vegetables, they are technically not plants but part of the kingdom called fungi. They are low in calories and have virtually no fat or cholesterol, making them a healthy addition to any diet.
