Mushrooms are classified as vegetables and have been consumed and used as medicine for thousands of years. They are low in calories, fat, and sodium, and provide protein, vitamins, and minerals. However, technically, mushrooms are not plants but fungi, a kingdom that includes molds and yeasts. They are dependent on other organisms for nutrition, unlike plants, which produce their own food through photosynthesis. This classification as fungi means that mushrooms are not scientifically considered vegetables, but the term vegetable is culinary rather than biological.

What You'll Learn
Mushrooms are classified as vegetables
Mushrooms have long been a part of the human diet and have been used as both food and medicine for thousands of years. They are low in calories, fat, and sodium and are a good source of B vitamins, selenium, copper, potassium, and fiber. They can also be a source of vitamin D when exposed to UV light.
The classification of mushrooms as vegetables may be due to their similar nutritional profiles. Mushrooms provide many of the same nutrients commonly found in vegetables, such as potassium, selenium, and fiber. They also contain non-nutritive plant substances such as polysaccharides, indoles, polyphenols, and carotenoids, which have been shown to have antioxidant, anti-inflammatory, and anticancer effects.
Additionally, mushrooms are recognized by chefs for their ability to create savory, rich flavors called umami due to the presence of the amino acid glutamate, which is also found in meats, fish, and cheeses. This culinary versatility and similarity to other vegetables in food preparation may contribute to their classification as vegetables.

They are part of the fungi kingdom
While mushrooms are commonly classified as vegetables, they are not plants. Instead, they are part of the fungi kingdom, which also includes molds and yeasts. Fungi are distinct from plants in that they cannot produce their own food through photosynthesis. Like animals, they are dependent on other organisms to provide their nutrition.
Mushrooms are the "fruiting bodies" of filamentous fungi that grow above the ground. Beneath the surface, a network of thread-like filaments called mycelium secretes enzymes that break down organic matter in the soil, which the fungi then absorb as nutrients. This unique growth process sets mushrooms apart from plants and aligns them more closely with animals in the biological world.
Despite being classified as fungi, mushrooms share some characteristics with plants and even animals. For example, mushrooms are a good source of B vitamins, selenium, potassium, and fiber—nutrients commonly found in vegetables and other food groups such as grains and meat. They also contain non-nutritive plant substances like polysaccharides, indoles, polyphenols, and carotenoids, which have been associated with antioxidant, anti-inflammatory, and anticancer effects in cell and animal studies.
In addition to their nutritional benefits, mushrooms have been used as medicine for thousands of years. Traditional and folk medicine practitioners value the bell-shaped fungi for their healing and cleansing properties. Modern research has also suggested that a higher intake of mushrooms may have protective effects on the brain in older adults, potentially reducing the risk of mild cognitive impairment.
While the term "vegetable" may evoke images of plants, it is important to remember that it is a culinary term rather than a scientific one. In the culinary world, mushrooms are considered vegetables due to their similar usage to other vegetables in food preparation. Thus, while mushrooms are technically fungi, they are widely accepted as honorary vegetables in the kitchen.

They are low in calories and fat
Although mushrooms are often classified as vegetables, they are technically not plants but part of the kingdom called fungi. They are low in calories and fat, with only 15 calories in a cup of raw mushrooms. They are also very low in sodium and have no cholesterol, making them a healthy choice.
Mushrooms are a good source of fibre, particularly soluble fibre like beta-glucan, and have a low glycemic index. They are considered a heart-healthy food choice due to their minuscule amount of fat, most of which is polyunsaturated. In addition, they provide some protein, with 2.2 grams per cup, and are a good source of B vitamins, selenium, copper, potassium, and iron.
The B vitamins in mushrooms include riboflavin, niacin (vitamin B3), pantothenic acid (vitamin B5), thiamine, B6, and B12. These vitamins assist in energy release from carbohydrates, protein, and fat. Niacin also contributes to the maintenance of connective tissues and supports antioxidant enzymes. Mushrooms are one of the few non-animal sources of vitamin D, especially when exposed to light, and this vitamin is important for bone health.
The USDA considers mushrooms as part of the vegetable group, and they can be used to reduce calories and fat in recipes without sacrificing satisfaction. For example, they can be sautéed, boiled, grilled, or baked as a side dish or incorporated into casseroles, burgers, or salads.

They are a good source of vitamins and minerals
While mushrooms are considered vegetables in a culinary context, they are technically classified as fungi. They are a good source of vitamins and minerals, including B vitamins such as riboflavin, niacin, and B6, as well as vitamin D, selenium, potassium, copper, and zinc. Vitamin D is important for bone and immune health, while selenium helps prevent cell damage and vitamin B6 aids in the formation of red blood cells.
Mushrooms are also a good source of protein and antioxidants, including choline and phenolic antioxidants. The antioxidants in mushrooms may help to boost the immune system and protect against certain diseases, including cancer, diabetes, and heart disease. Additionally, mushrooms are low in calories and fat, making them a healthy addition to any diet.
The vitamin D content in mushrooms can vary depending on their exposure to UV light. Wild mushrooms like chanterelles and morels tend to have higher levels of vitamin D, while those grown in darkened conditions, such as white button mushrooms, have lower levels. However, exposing mushrooms to UV light, either naturally or through a UV lamp, can significantly increase their vitamin D content.
Mushrooms also contain a substance called ergosterol, which is similar to cholesterol in animals. Ergosterol can be converted into vitamin D when exposed to ultraviolet light. This makes mushrooms the only vegan, non-fortified dietary source of vitamin D, providing an important source of this vitamin for those following a plant-based diet.
Overall, mushrooms are a nutritious food that offers a wide range of health benefits due to their vitamin and mineral content. They can be easily incorporated into various recipes, adding both flavour and nutritional value to meals.

They have been used as food and medicine for thousands of years
While mushrooms are often classified as vegetables, they are technically not plants but fungi. They share some characteristics with plants and even with animals. Mushrooms have been consumed and used as medicine for thousands of years.
The ancient Greeks believed that mushrooms gave warriors strength in battle, and the Romans considered them the "Food of the Gods." Traditional and folk medicine practitioners laud the bell-shaped fungi for their healing and cleansing properties. The Greek physician Hippocrates, circa 450 BCE, classified the amadou mushroom as a potent anti-inflammatory and for cauterizing wounds. The "mushroom of immortality," commonly known as Lingzhi or Reishi, has been used in traditional Chinese medicine to improve health and longevity for thousands of years. It has also been used in the treatment of neurasthenia, hypertension, hepatopathy, and carcinoma.
The first peoples of North America used puffball mushrooms as wound healers. Ancient Chinese culture has treasured mushrooms as a health food, an "elixir of life." Mushrooms are low in calories, carbohydrates, fat, and sodium, and they are cholesterol-free. They provide important nutrients, including selenium, potassium, riboflavin, niacin, vitamin D, protein, and fiber.
Mushrooms also contain non-nutritive plant substances such as polysaccharides, indoles, polyphenols, and carotenoids, which have been shown to have antioxidant, anti-inflammatory, and anticancer effects. Beta-glucans, for example, are not synthesized by humans and are not recognized by the human immune system, but they have been consumed for thousands of years and are believed to improve general health. They are responsible for the anticancer, anticholesterolemic, antioxidant, and neuroprotective activities of many edible mushrooms.
In addition to their culinary and medicinal uses, mushrooms also have cultural significance. For instance, truffles, a type of fungus generally classified as a mushroom, are famously expensive and may be served sparingly as fresh shavings or infused into sauces, often paired with rich cheese and meat dishes.
