Mushrooms are a staple in many vegan diets, thanks to their delicious umami flavour and nutrient density. But are they actually vegan? Mushrooms are neither plants nor animals. They belong to a separate classification: the Fungi kingdom. They don't have a central nervous system, so most people feel that eating them is not cruel or exploitative. They can be grown sustainably without the use of animal byproducts. However, some mushrooms are carnivorous, ensnaring and digesting tiny living organisms like nematodes. Despite this, the general consensus is that mushrooms are indeed vegan.

What You'll Learn
Mushrooms are fungi, not animals
Mushrooms are a nutritious and tasty food, but some people wonder whether they are suitable for vegans. After all, they are not exactly plants, but they are not animals either.
Mushrooms are a type of fungus, belonging to their own kingdom separate from the kingdoms of plants and animals. Biologists use these kingdoms to categorise living things. Fungi are distinct from plants in several ways, including the fact that they do not produce their own food through photosynthesis. Instead, mushrooms absorb nutrients from their environment. They grow from spores, not seeds, and feed on deadwood and organic matter, including decaying plants, animals, and other fungi.
Some people argue that mushrooms are not vegan because, on a cellular level, they have more in common with animals than plants. This is because their cell walls are made of chitin, which is also found in the shells of crustaceans like shrimps, crabs, and lobsters. However, this argument has been criticised as a meaningless distinction.
The main factor that vegans use to determine whether a food is suitable for them is whether it comes from a living thing that is biologically classified as an animal. Since mushrooms are not animals, most people consider them to be vegan. They do not have a central nervous system, so eating them is not considered cruel or exploitative. They can be grown sustainably without the use of any animal byproducts.
However, there is some controversy surrounding certain types of mushrooms, such as oyster mushrooms, which attract and feed on nitrogen-rich prey, including small roundworms. This carnivorous behaviour has led some people to question whether these mushrooms should be considered vegan. Ultimately, whether someone chooses to eat mushrooms or not is a personal decision.

They don't feel pain
Mushrooms are a nutritious and tasty food group. They are neither plants nor animals, but belong to the Fungi kingdom. They are stationary like plants, but they cannot produce their own food through photosynthesis. Instead, some mushrooms rely on other organisms as food sources.
Mushrooms do not have a central nervous system, and therefore, do not feel pain. They are not sentient beings. They are grown in a way that does not harm animals, which aligns with the principles of veganism.
While most mushrooms are saprophytic, living off decaying organic matter from plants, animals, or other fungi, certain species are carnivorous. These carnivorous mushrooms trap and digest tiny living organisms like nematodes to obtain enough nutrients to grow. Despite this, the general consensus is that mushrooms are vegan.
Mushrooms are a good source of vitamin D, which is often lacking in a vegan diet. They can be used as a meat substitute, providing a hearty, umami flavor and a meaty texture. They can be added to various dishes, including pasta sauce and Chinese cuisine, or simply sautéed in vegan butter and soy sauce.
In conclusion, mushrooms are considered vegan-friendly as they do not feel pain due to the absence of a nervous system. They are a nutritious and versatile ingredient that can enhance the flavor and health benefits of a vegan diet.

They're grown without harming animals
Mushrooms are vegan because they are grown without harming animals. They are not animals, but fungi, and belong to a kingdom of their own, separate from plants and animals. They do not have a central nervous system, so they cannot feel pain and are not sentient beings.
Mushrooms are grown in a variety of ways, some of which may involve animal products. For example, they may be grown on animal manure, but this is simply a nutrient-rich substrate that helps the mushrooms grow. It is also difficult to ensure that the soil in which mushrooms are grown does not contain decomposing animal matter, just as vegetables may be grown in soil containing earthworms or dead insects.
The production of mushrooms does not involve the harm or exploitation of animals. They are typically grown in dark sheds with artificial lighting and no contact with the outside world to avoid contamination from other fungi. This means there are no accidental crop deaths involved in producing them, which is not always the case with other farmed produce.
Some people argue that certain types of mushrooms, such as oyster mushrooms, are not vegan because they feed on nitrogen-rich prey, including small roundworms. However, this is a natural part of their growth process, and it is impossible to control whether the soil in which other vegan foods are grown contains similar decomposing animal matter.
Overall, mushrooms are considered vegan because they are grown without causing harm to animals and are not derived from animals. They are a popular food among vegans due to their nutritional benefits, distinct umami flavor, and versatility in cooking.

Oyster mushrooms are controversial
Oyster mushrooms, or Pleurotus species, are a group of gilled mushrooms. They are neither plants nor animals but fungi. They are one of the most popular mushrooms in the world and are commonly enjoyed in dishes like pasta and stir-fries. They are also used in traditional medicine and dietary supplements.
Oyster mushrooms are a good source of fiber, protein, and a variety of vitamins and minerals. They provide antioxidants, which are substances that help reduce cellular damage in the body. For example, seven phenolic compounds have been detected in P. ostreatus extracts, including gallic acid, chlorogenic acid, and naringenin — all of which act as antioxidants.
Despite their health benefits, oyster mushrooms are controversial because they are an invasive species. A study by Andi Reisdorf examined the spread of non-native golden oyster mushrooms, which are native to the subtropical hardwood forests of eastern Russia, northern China, and Japan. The study found that golden oyster mushrooms are spreading quickly and widely outside of their native range, with their invaded range continuing to expand and their density increasing. This poses a threat to biodiversity, which is important for ecosystem function.
In addition to the concerns about the impact of invasive oyster mushrooms on biodiversity, there are also worries about the potential introduction of new fungal diseases due to shifts in temperature and other conditions. Oyster mushrooms are also one of the few mushroom species that are carnivorous. They ensnare and digest tiny living organisms like nematodes to get enough nutrients to grow. However, it is important to note that oyster mushrooms do not possess a nervous system, meaning they do not feel pain. The general consensus is that, despite their carnivorous habits, they are still considered vegan.

They're a nutritious vegan food
Mushrooms are a nutritious vegan food, packed with essential micronutrients and health benefits. They are low in calories, fat, cholesterol, and sodium, but high in fibre, protein, antioxidants, vitamins, and minerals. Mushrooms are one of the few plant-based sources of vitamin D, which is often lacking in a vegan diet.
Mushrooms are also a great meat substitute, with a hearty, umami flavour and a meaty texture that can make any dish feel indulgent. For example, a portobello mushroom burger is a game-changer. They are versatile and can be infused into many vegan dishes, such as pasta sauce or Chinese cuisine, or simply sautéed in vegan butter and soy sauce.
Mushrooms are neither plants nor animals. They are classified in the Fungi kingdom, which also includes yeasts and moulds. They do not have a central nervous system, so most people feel that eating them is not cruel or exploitative. They can be grown sustainably without the use of animal by-products, and their production does not harm any animals, aligning with vegan principles.
However, there is some controversy regarding certain types of mushrooms, such as oyster mushrooms. Oyster mushrooms are a predator to small organisms, ensnaring and digesting tiny living organisms like nematodes to obtain enough nutrients to grow. This carnivorous habit has led to debates about whether these mushrooms are truly vegan. Ultimately, it is a personal decision, and many people continue to consider mushrooms a nutritious and tasty vegan food option.

Frequently asked questions
Yes, mushrooms are vegan. They are categorised in the Fungi kingdom, not the Animalia kingdom. They do not have a central nervous system and are not sentient, so most people feel that eating them is not cruel or exploitative.
Mushrooms are neither plants nor animals, which leads to some confusion. On a cellular level, fungi share similarities with animals as their cell walls are made of chitin, which is also found in crustaceans. Some mushrooms, like oyster mushrooms, feed on nitrogen-rich prey such as nematodes.
Truffles are a type of mushroom that some vegans choose to avoid. Truffle hunting involves the use of animals, which can be inhumane and may result in poisoning if the animal eats the wrong type of mushroom.
Mushrooms are a good source of potassium and vitamin D, which can be lacking in a vegan diet. They are also low in calories and high in fibre, making them a suitable meat substitute.
