Fungi are part of the microbiota, the set of microorganisms that inhabit different parts of the human body, such as the skin, mouth or intestine. The microbiota is essential for the proper functioning of the immune system, digestion and metabolism. The fungi that are part of the microbiota are called mycobiota and are mainly yeasts of the genus Candida.

The mycobiota can be altered by various factors, such as the use of antibiotics, stress or diet, which can lead to an imbalance between beneficial microorganisms and pathogens. This imbalance is known as dysbiosis and can cause various diseases, such as fungal infections, allergies or intestinal inflammation.

Fungi also play a key role in food and drug production. Some fungi are edible and have high nutritional and medicinal value, such as mushrooms, mushrooms or truffles. Other mushrooms are used to ferment foods and beverages, such as bread, cheese, wine or beer. Mushrooms are also a source of bioactive substances with antibiotic, antitumor or immunomodulatory properties, such as penicillin, cyclosporine or PSK.

Fungi also play a fundamental role in environmental health, as they are responsible for the decomposition of organic matter and the recycling of nutrients in ecosystems. Fungi form symbiotic associations with plants, called mycorrhizae, which enhance their growth and resistance to pests and diseases. Fungi can also be used as biological control agents for insects harmful to agriculture.

Fungi and their relationship to health

Fungi are a group of heterotrophic organisms belonging to the kingdom Fungi. Although often classified as plants, fungi are actually a separate group of organisms characterized by their ability to break down organic matter and their role in the production of food, medicines and other products useful to humans.

Although some fungi are toxic and can cause serious diseases, many others have medicinal properties and can be beneficial to human health. In fact, some of the most important drugs in modern medicine are derived from natural compounds produced by fungi.

The relationship between fungi and human health is very complex and multifaceted. In this introduction, we will explore some of the ways in which fungi can affect our health and well-being.

Another study conducted in Japan in the same year found that antioxidant compounds present in mushrooms could reduce the risk of developing type 2 diabetes.

In addition to their effect on physical health, some studies have shown that mushrooms can also have a positive effect on mental health. For example, a 2016 study in China found that reishi extract could improve symptoms of depression in patients with chronic kidney disease.

Bioactive compounds in mushrooms and their effects on the human body

Mushrooms are a rich source of bioactive compounds that can provide a variety of benefits to human health. These compounds are produced by mushrooms to protect against pathogens and predators, and can have positive effects on the human body when consumed as part of a balanced diet.

One of the best known compounds in mushrooms is ergothioneine, an antioxidant that has been shown to have a protective effect on DNA and cells. Ergothioneine is found in significant amounts in mushrooms such as mushroom, oyster and shiitake.

Another bioactive compound present in mushrooms is beta-glucan, a soluble fiber that has been shown to have beneficial effects on immune system health. Beta-glucans can help improve the body’s immune response to diseases and pathogens, and are found in mushrooms such as reishi, maitake and shiitake.

In addition to ergothioneine and beta-glucans, mushrooms also contain a variety of antioxidant and anti-inflammatory compounds that may help reduce the risk of chronic diseases such as cancer and cardiovascular disease. These compounds include polysaccharides, polyphenols and triterpenes, which are found in mushrooms such as reishi, chaga and cordyceps.

Regular consumption of mushrooms may also help improve brain and nervous system health. Some mushrooms contain neuroprotective compounds, such as hericenone and erinacin, which have been shown to help protect nerve cells and improve memory and cognition. These compounds are found in mushrooms such as lion’s mane and reishi.
