Mushrooms: Ancient Fungi With A Long History

The evolution of the kingdom Fungi, more commonly known as mushrooms, is a mysterious topic. Only 2% of species have been identified, and their delicate nature means fossils are rare and difficult to discern from other microorganisms. The earliest fossils possessing features typical of fungi date to the Paleoproterozoic era, some 2,400 million years ago. However, a recent study of ancient rocks with fossilized mycelium in the Democratic Republic of the Congo dated the fossils to between 715 and 810 million years old, 300 million years older than previously thought.

Mushrooms contain ergothioneine, an antioxidant that fights age-related diseases

Mushrooms are a leading source of ergothioneine (EGT), a potent antioxidant. EGT is a naturally occurring amino acid that can also be found in common foods such as oat bran, grains, and chicken liver. However, mushrooms are the best dietary source of this antioxidant.

EGT does not undergo auto-oxidation, unlike other antioxidants such as glutathione, due to its stability by existing in thiol-thione tautomerism form. It is also a powerful scavenger of free radicals, is anti-inflammatory, and has anti-aging properties. Mushrooms are also a source of other antioxidants such as glutathione, phenolics, flavonoids, polysaccharides, vitamins, carotenoids, and minerals.

The amount of ergothioneine in mushrooms varies by species, with the porcini species, a wild variety, containing the highest amount of the compound among the 13 species tested. The more common mushroom types, like the white button, have less ergothioneine, but still have higher amounts than most other foods. Cooking mushrooms does not seem to significantly affect their ergothioneine content.

The presence of ergothioneine in mushrooms may be linked to their potential to fight age-related diseases. Oxidative stress, a condition of redox imbalance resulting from excessive production of reactive oxygen species, is a common feature in the brains of elderly people, contributing to neurodegenerative diseases (NDs). Antioxidants can help protect against this oxidative stress.

According to researchers, ergothioneine-rich mushrooms may act as a potential therapeutic strategy for the elimination of senescent cells in neurodegenerative diseases. Countries with more ergothioneine in their diets, such as France and Italy, also have lower incidents of neurodegenerative diseases. Mushrooms have also been studied for their potential role in treating other age-related diseases, including cancer, cardiovascular disease, and diabetes.

The anti-aging properties of mushrooms may be due to their bioactive compounds

Aging is a complex biological process influenced by both intrinsic and extrinsic factors. It has been discovered that reactive oxygen species can accelerate aging, leading to an increased risk of age-related diseases. Mushrooms, as a dietary intervention, have recently gained attention for their potential anti-aging properties. This is mainly attributed to their rich content of various bioactive compounds, which offer promising benefits in combating skin aging and age-related diseases.

Mushrooms are a rich source of bioactive compounds, including carbohydrates, bioactive proteins, fungal lipids, and phenolic compounds. In vitro and in vivo studies have demonstrated that treatments with mushrooms or their extracts can significantly extend lifespan and improve health span. The precise cellular and molecular mechanisms of action of these bioactive compounds are still being elucidated.

One notable bioactive compound found in mushrooms is ergothioneine, a powerful antioxidant. Mushrooms have been found to contain high levels of ergothioneine, with some species, like the wild porcini mushroom, containing significantly higher amounts. Ergothioneine is heat stable, allowing it to retain its properties even when mushrooms are cooked. It plays a crucial role in protecting against oxidative stress, which is a key factor in the aging process and the development of age-related diseases.

Additionally, mushrooms contain other bioactive compounds such as β-glucans, lectins, and linolenic acids, which contribute to their pharmacological activities. These compounds may enhance the immune system and strengthen the body's biological functions. Regular intake of mushrooms or their extracts may help alleviate age-related diseases and promote overall health.

In conclusion, the anti-aging properties of mushrooms are likely due to their diverse range of bioactive compounds. These compounds exhibit anti-oxidant, immunomodulatory, neuroprotective, anti-inflammatory, and anti-cancer properties, contributing to their potential health benefits in combating aging and age-related conditions. Further research and clinical trials are needed to fully understand the mechanisms and explore the potential benefits of mushrooms in anti-aging practices.

Mushrooms are used in traditional therapies like Chinese medicine and Indian Ayurveda medicine

Mushrooms have been used in traditional therapies like Chinese medicine and Indian Ayurveda medicine for thousands of years. In traditional Chinese medicine (TCM), mushrooms are believed to have healing properties and are used to promote health, bolster immunity, and prevent and treat various diseases. TCM is a holistic branch of medicine that has been practised in China for thousands of years, encompassing herbal medicine, acupuncture, massage, tai chi, and dietary therapy.

One of the most famous medicinal mushrooms in TCM is the ganoderma mushroom, known as "lingzhi" in Chinese and "reishi" in Japanese. It has been used for its medicinal properties for around 4,000 years to treat ailments such as arthritis, insomnia, and gastric ulcers. It is also believed to increase longevity and is sometimes referred to as the "mushroom of immortality". Other well-known medicinal mushrooms in TCM include lion's mane, chaga, cordyceps, shiitake, and tremella. Lion's mane is traditionally used to improve digestion and modern research suggests it may also improve cognition, memory, and nerve function. Chaga is used to reduce fatigue, increase focus, and promote overall health and longevity. Cordyceps is known for its ability to improve lung and cardiovascular function, as well as its anti-tumour effects. Shiitake mushrooms have been cultivated in China for about a thousand years and are used for their culinary and medicinal properties. Tremella is a medicinal mushroom that is known for its ability to nourish the skin and treat dry coughs.

In addition to these well-known species, there are many other types of medicinal mushrooms used in TCM. The oldest official list of medicinal substances in TCM, the Shennong Bencao Jing, dates back to the 29th century BC and includes various mushroom species. Modern research is now beginning to test and validate the traditional uses of these mushrooms, with exciting early findings.

While the focus here is on TCM, it is worth noting that mushrooms have also been used in other traditional medicine systems in Eastern countries such as Japan and Malaysia, as well as in Indian Ayurveda medicine. However, the specific details of mushroom usage in these other traditional medicine systems were not readily available.

Mushrooms are a dietary source of ergothioneine, which may be a useful tool in fighting age-related diseases

Mushrooms are a leading dietary source of ergothioneine, a potent antioxidant that may be key to fighting age-related diseases. Also known as ERGO, ergothioneine is an amino acid made primarily by fungi and found in high concentrations in mushrooms.

As people age, inflammation and oxidation can contribute to many diseases associated with getting older, such as Parkinson's disease and Alzheimer's disease. Research has found that ergothioneine, a powerful antioxidant, may be a useful tool in fighting these conditions.

The human body does not produce ergothioneine, so it must be obtained from dietary sources. Fortunately, the body has a dedicated and highly specific transport system for ergothioneine that pulls it from food into red blood cells and distributes it throughout the body. This is a strong indication of its importance in preventing chronic disease, and some scientists now refer to ergothioneine as a 'longevity vitamin'.

Mushrooms have been found to contain the highest sources of ergothioneine compared to any other food. The shiitake mushroom, in particular, has been found to contain the highest ergothioneine content. In addition to their ergothioneine content, mushrooms are also an excellent source of other primary and secondary metabolites such as riboflavin, selenium, vitamin D, beta-glucan, erinacine, hericenones, and ergosterol.

The amino acid ergothioneine is found in high concentrations in mushrooms and may promote healthy aging

Aging is a complex biological process influenced by both intrinsic and extrinsic factors. One of the critical factors contributing to aging is the accumulation of reactive oxygen species (ROS), which accelerates the aging process and leads to an increased incidence of age-related diseases. To mitigate this, a functional food with high antioxidant compounds can be used to counteract the damaging effects of ROS and modulate the aging process.

Mushrooms, being rich in various bioactive compounds, have emerged as a promising dietary intervention for anti-aging and promoting healthy aging. They contain carbohydrates, bioactive proteins, fungal lipids, and phenolic compounds, all of which contribute to their potential anti-aging properties. Additionally, mushrooms are an excellent source of primary and secondary metabolites such as riboflavin, selenium, vitamin D, beta-glucan, erinacine, hericenones, and ergosterol.

Among the bioactive compounds found in mushrooms, ergothioneine (EGT) stands out as a vital amino acid that may promote healthy aging. EGT is a naturally occurring water-soluble sulfur-containing amino acid and a potent antioxidant. It is made primarily by fungi and found in high concentrations in mushrooms. The discovery of a specific transporter for EGT in humans allows for its rapid movement from food into red blood cells and effective distribution throughout body tissues.

The presence of EGT in mushrooms makes them a potential candidate for anti-aging exploration through the elimination of neuronal senescent cells. Studies have shown that EGT-rich mushrooms, such as the shiitake mushroom, possess neuroprotective effects due to their potent antioxidant properties. By scavenging free radicals and inhibiting specific cellular pathways, EGT-rich mushrooms may help delay or prevent age-related diseases, particularly those associated with oxidative stress, such as Alzheimer's and Parkinson's disease. Furthermore, EGT-rich mushrooms can improve cell viability and reduce reactive oxygen species, contributing to their potential anti-aging effects.
