Mushrooms are a fun food group and an essential ingredient in many dishes. They are often used as a vegetarian meat substitute and are considered very healthy. But are they vegetables? Mushrooms are technically a type of fungi, as they do not have leaves, roots, or seeds and do not need light to grow. However, they are considered vegetables from a nutritional standpoint, as they provide many of the same nutritional attributes as vegetables.

What You'll Learn
Mushrooms are a type of fungi
Mushrooms are commonly placed in the vegetable category for dietary recommendations. They are nutrient-dense, providing a lot of nutrition for very few calories, mostly in the form of carbohydrates, including fibre. They are also a good source of B vitamins, iron, potassium, and other minerals. Mushrooms are one of the few food sources that naturally contain a good amount of vitamin D, which is usually associated with dairy products. Like humans, mushrooms exposed to sunlight produce vitamin D.
Mushrooms are also environmentally friendly. They don't require much water or energy, and can grow without sunlight. They are often used as a vegetarian meat substitute, and can be used in a wide range of dishes.
While mushrooms are not technically vegetables, their nutritional profile is similar to that of vegetables. They are considered vegetables by the U.S. Department of Agriculture due to their nutritional attributes.

They are not plants
Mushrooms are not plants, and therefore, they are not vegetables. They are a type of fungus, belonging to a separate biological kingdom that also includes molds and yeasts. Fungi are distinct from plants in several ways, including their cellular organization and composition, such as containing chitin and ergosterol. Plants are capable of producing their own food through photosynthesis, converting sunlight, water, and carbon dioxide into energy. In contrast, fungi are dependent on other organisms for their nutrition, as they lack chlorophyll and must obtain carbohydrates from plants.
Mushrooms, specifically the "fruiting bodies" that appear above the ground, do not have leaves, roots, or seeds, and they do not require light to grow. This differentiates them from plants, which rely on sunlight to photosynthesize their food. While mushrooms are often cooked and eaten like vegetables, and they are considered vegetables by the U.S. Department of Agriculture from a nutritional standpoint, taxonomically and scientifically, they are classified as fungi.
The nutritional profile of mushrooms also sets them apart from plants. While plants obtain their energy through photosynthesis, mushrooms, like animals, are dependent on other organisms for their nutrition. Additionally, mushrooms are a potential source of vitamin D, which further distinguishes them from plants. Mushrooms exposed to sunlight can produce vitamin D, similar to humans. This unique characteristic has led to the use of commercial treatments to enhance the vitamin D content of some mushrooms.
The classification of mushrooms as fungi, rather than plants, is supported by their unique living conditions and growth habits. Mushrooms do not require fields or sunlight to grow and can thrive in dark, underground environments. Mushroom farming can be an excellent solution for areas with poor, barren farmland, as it does not require large spaces or extensive sunlight. This adaptability and resource efficiency contribute to the perception of mushrooms as distinct from typical plants.

Mushrooms are nutrient-dense
Although mushrooms are not technically vegetables, they are nutrient-dense. They are a good source of B vitamins, potassium, and vitamin D. Mushrooms are also a source of antioxidants, including selenium, an essential mineral that helps minimize cell damage and potentially reduces the risk of chronic diseases.
Mushrooms are low in calories and fat, with modest amounts of fibre and various other nutrients. They are also a good source of protein, with white mushrooms being the most protein-dense on a per-calorie basis, and oyster mushrooms having the most protein by weight. Mushrooms have a unique nutrient profile, containing ergosterol, a substance similar to cholesterol, which can be transformed into vitamin D with exposure to ultraviolet light.
Mushrooms are also recognized for their culinary uses, particularly their ability to create a savoury, rich flavour called umami, thanks to the presence of the amino acid glutamate. This makes them a suitable substitute for meat in many dishes, and they can be used to reduce the overall energy density of a meal.
Mushrooms have been consumed and used medicinally for thousands of years, with traditional and folk medicine practitioners recognizing their healing and cleansing properties. They are also environmentally friendly, requiring less water and energy to grow compared to other foods.
While mushrooms may not be vegetables in a strict botanical sense, their nutritional profile and culinary applications make them a valuable addition to any diet.

They are a good source of vitamin D
Mushrooms offer a unique and valuable contribution to our diets, especially regarding vitamin D content. While most vegetables and fruits are typically associated with providing vitamins A, C, and K, mushrooms stand out for their exceptional ability to produce and provide us with vitamin D. This is a distinctive feature, as vitamin D is not commonly found in plant-based sources; it is predominantly present in animal-derived foods, such as fatty fish and egg yolks. Vitamin D is essential for maintaining healthy bones, teeth, and muscles, and it also supports our immune system and overall health.
Mushrooms are one of the few non-fortified food sources that can naturally provide us with a substantial amount of this vital nutrient. When exposed to sunlight or UV light, mushrooms have the unique ability to produce vitamin D2, a form of vitamin D that is effectively utilized by the human body. This process is similar to how our skin synthesizes vitamin D3 from sunlight. By simply exposing mushrooms to sunlight before consumption or purchasing mushrooms that have been treated with UV light during cultivation, we can benefit from this valuable nutrient.
The vitamin D content in mushrooms can vary depending on the species and the amount of UV light exposure. For example, button mushrooms, when exposed to UV light, can provide up to 80% of the recommended daily intake of vitamin D in just a single 80-gram serving. This makes mushrooms an excellent option for individuals who may not obtain sufficient vitamin D from other dietary sources or sunlight exposure, such as those following vegetarian or vegan diets, or those with limited sun exposure due to geographical location or lifestyle factors.
Additionally, mushrooms are a versatile ingredient that can be easily incorporated into a variety of dishes, making it convenient to boost vitamin D intake. They can be enjoyed raw, grilled, roasted, or sautéed, and their earthy flavor and meaty texture make them a satisfying addition to meals. By including mushrooms in our diets on a regular basis, we can not only benefit from their vitamin D content but also take advantage of their other nutritional offerings, including B vitamins, potassium, and antioxidants. Overall, mushrooms are a valuable and accessible source of vitamin D, contributing to our overall health and well-being.

Mushrooms are environmentally friendly
Although mushrooms are not technically vegetables, they are environmentally friendly. They are a type of fungi, which play an important role in the ecosystem. Fungi and mushrooms break down dead organic matter, creating rich soil in which plants can thrive.
Mushrooms can also be cultivated in a controlled indoor environment, using waste products like straw, sawdust, and agricultural byproducts. This means that mushrooms can be grown without the need for large amounts of land, water, and other resources, reducing the environmental impact of food production. Furthermore, mushrooms can be grown year-round, providing a consistent source of food.
Mushroom farms can also act as disposal agents, using agricultural and industrial waste products for compost. This helps to control pollution and reduce waste sent to landfills. For example, one Pennsylvania farm has successfully used leaves collected during the fall in their composting process.
Additionally, mushrooms grown indoors require fewer pesticides and herbicides, further reducing their environmental impact. Some mushrooms can even be used to remediate contaminated soil and water, breaking down harmful chemicals and toxins.
Overall, mushrooms are an environmentally friendly food source that can help promote sustainable agricultural practices.
