Mushrooms are a nutritious and tasty food, but can vegans eat them? Mushrooms are neither plants nor animals, but belong to the fungi kingdom. They are stationary like plants, but feed on decaying organic matter from plants, animals, or other fungi. Some species, including oyster mushrooms, even feed on small living organisms. This has sparked debate about whether mushrooms are vegan-friendly.

What You'll Learn
Mushrooms are fungi, not plants or animals
Mushrooms are a type of fungi, and while they may share some characteristics with plants, they are not plants. Fungi form a separate kingdom of life, distinct from the kingdoms of plants and animals.
The classification of mushrooms as fungi can be traced back to early taxonomists who observed that fungi were immobile and had rigid cell walls. These characteristics were sufficient for early scientists to determine that fungi were not animals and were not closely related to plants.
However, fungi are more closely related to animals than they are to plants. This is supported by molecular evidence that indicates fungi and animals shared a common ancestor in the form of an opisthokont, a cell with a posterior flagellum similar to human spermatozoids.
Fungi have unique characteristics that distinguish them from plants and animals. Unlike plants, fungi do not photosynthesize, and unlike animals, they do not ingest their food. Instead, fungi live inside their food and secrete enzymes to dissolve the nutrients they absorb.
Because mushrooms are categorised as fungi, they are generally considered suitable for vegan diets. Most people consider mushrooms vegan because they are not classified as animals and do not have a central nervous system, so eating them is not considered cruel or exploitative. Additionally, mushrooms can be grown sustainably without the use of animal byproducts.

They don't have a central nervous system
Mushrooms are a part of the Fungi kingdom, a separate lineage of life from plants and animals. They are not derived from any animal or animal byproduct, and they do not have a central nervous system or the capacity to feel pain. Therefore, eating mushrooms is not considered cruel or exploitative, and they are a perfect fit for vegan diets.
Mushrooms are highly valued in vegan cuisine for their rich, umami flavour, which can mimic meat. They are also nutrient-rich, providing a good source of vitamins, minerals, antioxidants, protein, and fibre. These nutritional benefits make mushrooms a popular choice for vegans, as they offer a satisfying alternative to animal proteins.
While mushrooms are widely considered vegan, there is some debate within the vegan community. Some argue that mushrooms are not plants and therefore not part of a "plant-based diet" because fungi are their own category. However, this is considered a meaningless semantic argument by some.
Another point of contention is the way mushrooms are grown. Some mushrooms may be grown on animal manure or started with spawn grown in gelatin, which some vegans may consider non-vegan. However, many mushrooms can be grown in a completely vegan way, typically on straw, sawdust, or coffee grounds. Wild mushrooms are also foraged from the natural ecosystem, further emphasising their vegan credentials.
Overall, while there may be some disagreement within the vegan community, the majority view is that mushrooms are suitable for vegans due to their lack of a central nervous system and their distinct classification in the Fungi kingdom.

They can be grown using animal products
Mushrooms are a contentious food for vegans, with some arguing that they are not 'fully vegan'. This is because mushrooms are not plants, but fungi, belonging to an entirely separate kingdom of life. This unique biological characteristic has sparked debate within the vegan community.
One argument against the vegan status of mushrooms is that they can be grown using animal products. For example, some mushrooms are grown on animal manure or started with spawn grown in gelatin. This is comparable to the argument made about bee-pollinated plants, which some argue are not vegan as they exploit the work of bees, and vegetables grown using fertilizer or compost made from animal waste or bones.
Mushrooms grown on farms may be cultivated in controlled environments, often on enriched substrates. While straw, sawdust, and coffee grounds are all vegan substrates, organic compost may contain animal products. When shopping for mushrooms, it can be difficult to know if they have been grown in a completely vegan way. Even organic farms are allowed to use natural fertilizers like chicken manure.
However, it is important to note that many mushrooms can be grown in a completely vegan way, and wild mushrooms are likely to be vegan as they are part of the natural ecosystem.

Wild mushrooms are part of the natural ecosystem
Mushrooms are generally considered vegan-friendly. They are categorised in the Fungi kingdom, not the Animalia kingdom, and do not have a central nervous system like animals do. They can be grown sustainably without the use of animal byproducts, and they are a nutritious food option for vegans.
However, some vegans may still have concerns about eating mushrooms. This is because some mushrooms may be grown using animal products, such as animal manure or gelatin. This argument could also be applied to many vegetables, which are often grown using fertiliser or compost made from animal waste.
Mushrooms also play a role in improving soil fertility and sequestering carbon, which helps to alleviate the effects of climate change. They can also remove contaminants like petroleum products from the soil.
Some types of mushrooms, such as morels, truffles, and chanterelles, are foraged for in the wild. This means they are part of the natural ecosystem and do not negatively impact the environment when harvested this way. Wild mushrooms can also be dried and preserved for later use.

Mushrooms are nutrient-dense and low-calorie
Mushrooms are nutrient-dense and low in calories. They are a good source of protein, vitamins, minerals, and antioxidants. The nutritional profiles vary between different types of mushrooms, but most provide the same nutrients per serving regardless of their shape or size.
White mushrooms, for example, are the most protein-dense variety on a per-calorie basis. Oyster mushrooms, on the other hand, have the most protein per weight. Oyster mushrooms are also notable for being grown in a completely vegan way, typically on straw, sawdust, or coffee grounds.
Mushrooms are a valuable part of a vegan diet due to their high nutrient content. They are widely used as a meat substitute because of their hearty texture and rich, savoury flavour, known as umami. This flavour comes from the presence of the amino acid glutamate, also found in meats, fish, and cheeses.
When cooking mushrooms, it is best to sauté them quickly over high heat or simmer them over low heat to preserve their nutrients.
