Wild mushroom extracts can inhibit bacterial biofilm formation
Mushrooms are a valuable source of food and income worldwide, and they also possess pharmaceutical qualities. While mushrooms are known to cause poisoning in some cases, they also offer many health benefits. Certain medicinal mushrooms have emerged as beneficial ingredients in dietary supplements.
Wild mushrooms have antimicrobial properties, and their extracts can be used to inhibit bacterial biofilm formation. Microorganisms can colonize a wide variety of medical devices, putting patients at risk for local and systemic infectious complications, including local-site infections, catheter-related bloodstream infections, and endocarditis. These microorganisms can grow on almost any surface, forming complex communities called biofilms.
The use of natural products has been successful in discovering new medicines, and mushrooms could be a source of natural antimicrobials. Wild mushroom extracts have been shown to inhibit in vitro biofilm formation by multi-resistant bacteria. For example, extracts of Russula delica, Fistulina hepatica, Mycena rosea, Leucopaxilus giganteus, and Lepista nuda have been found to inhibit biofilm formation by four Gram-negative bacteria (Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, and Acinetobacter baumannii).
The extracts of certain wild mushrooms, such as Auricularia auricula-judae, Microporus xanthopus, Termitomyces umkowaani, Trametes elegans, and Trametes versicolor, have demonstrated considerable biofilm-inhibitory efficacy against test organisms like Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The potential of these extracts to inhibit bacteria's biofilm-formation processes could lead to the discovery of new chemicals for use in clinical settings.

Mushrooms contain phytochemicals with antimicrobial properties
Mushrooms are a valuable source of food and income worldwide, and they also possess medicinal qualities. They contain phytochemicals with antimicrobial properties, which can be used to develop novel antimicrobial chemotherapeutic agents.
A study on the phytochemical profile and antimicrobial activities of the edible mushroom Termitomyces striatus revealed the presence of alkaloids, flavonoids, steroids, sterols, saponins, phenols, carbohydrates, and proteins. The extracts from this mushroom exhibited antibacterial activity against several bacterial strains, including P. aeruginosa, E. coli, B. subtilis, and S. aureus.
Another study examined the antimicrobial properties of wild mushroom extracts, specifically their ability to inhibit bacterial biofilm formation by multi-resistant bacteria. The extracts of Russula delica, Fistulina hepatica, Mycena rosea, Leucopaxilus giganteus, and Lepista nuda showed promising results in inhibiting biofilm production.
Additionally, a component of the mushroom Taiwanofungus camphoratus (Tc) has been found to possess antimicrobial potential, inhibiting the growth of fungi and bacteria in foods. Tc helps lower the contamination rate of toxin-producing or heat-tolerant fungi that may escape the food sanitation process.
While mushrooms have antimicrobial properties, they also contain polysaccharides, their most abundant carbohydrate, which stimulate the growth of healthy bacteria in the body. These polysaccharides pass through the stomach unchanged and reach the colon to encourage the growth of beneficial bacteria.
Overall, the phytochemicals present in mushrooms contribute to their antimicrobial properties, making them a valuable source of bioactive compounds with potential therapeutic benefits.

Mushrooms can reduce the risk of cancer
Mushrooms are a fungus that has become a staple in many meals. They are a valuable source of food and income worldwide and are known to have pharmaceutical qualities. Research has shown that mushrooms are rich in bioactive compounds and contain polysaccharides, the most abundant carbohydrate in mushrooms. This makes them a powerful source of ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage.
A review of 17 cancer studies from 1966 to 2020 shows that eating just 18 grams of mushrooms daily may lower your risk of cancer by as much as 45%. This is because mushrooms are the highest dietary source of ergothioneine, a potent antioxidant and cellular protector. Replenishing antioxidants in the body may help protect against oxidative stress and lower the risk of cancer.
When specific cancers were examined, researchers noted the strongest associations for breast cancer. Individuals who regularly ate mushrooms had a significantly lower risk of breast cancer. This could be because most of the studies did not include other forms of cancer. Moving forward, this research could be helpful in further exploring the protective effects of mushrooms and helping to establish healthier diets that prevent cancer.
In addition to their cancer-fighting properties, mushrooms have been found to have antimicrobial properties. Wild mushroom extracts have been shown to inhibit in vitro biofilm formation by multi-resistant bacteria. This suggests that mushrooms could be a source of natural antimicrobials and could be developed as a food ingredient to inhibit the growth of fungi and bacteria in foods.

Mushrooms are a low-sodium alternative to salt
Mushrooms are a healthy, low-sodium alternative to salt. They have a savoury flavour that can enhance meals without the need to add salt, thereby reducing sodium intake. A study from the Culinary Institute of America and UC Davis found that substituting half the meat in a traditional ground beef recipe with mushrooms maintained flavour while reducing sodium intake by 25%.
Mushrooms are a good source of vitamin D, which is produced when they are exposed to UV light or sunlight. Vitamin D helps the body absorb calcium, maintain and build strong bones, and reduce inflammation. They are also a source of vitamin B6, which helps the body form red blood cells, proteins, and DNA. Shiitake mushrooms, in particular, are a good source of vitamin B6.
Mushrooms are also a valuable source of ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage. A review of 17 cancer studies found that consuming just 18 grams of mushrooms daily may lower the risk of cancer by up to 45%.
In addition to their nutritional benefits, mushrooms have antimicrobial properties. Wild mushroom extracts have been shown to inhibit the formation of bacterial biofilms, demonstrating their potential as a natural source of antimicrobials.

Mushrooms contain polysaccharides that encourage healthy bacteria growth
Mushrooms are a valuable food source worldwide and are known to possess medicinal qualities. Research has shown that mushrooms contain polysaccharides, their most abundant carbohydrate, which stimulate the growth of healthy bacteria in the body.
Mushrooms are a type of fungus, and while many foods break down with stomach acid, the polysaccharides found in mushrooms pass through the stomach unchanged. They can reach the colon and encourage the growth of healthy bacteria. These polysaccharides are known as edible mushroom polysaccharides (EMPs), which are bioactive fibres derived from mushrooms. They have anti-tumour, antioxidant, antiviral, hypoglycaemic, and immunomodulatory effects.
EMPs are resistant to human digestive enzymes and provide a crucial source of energy for the gut microbiome. They promote the growth of beneficial bacteria and positively impact human health by regulating the composition of the gut microbiome. For example, Tremella fuciformis polysaccharide (TPs), a type of EMP, can substantially increase the diversity of the gut microbiota and restore the relative abundance of certain bacterial species, such as Odoribacter, Lactobacillus, Marinifilaceae, and Ruminococcaceae.
Additionally, wild mushroom extracts have been found to inhibit the formation of bacterial biofilms, which can cause local and systemic infectious complications in patients. The antimicrobial properties of mushrooms have been explored for their potential to make food crops safer and mitigate chronic human health conditions. For instance, pinecone cap mushrooms are effective in the fight against Aspergillus flavus, a carcinogenic fungus that contaminates many major crops.
In summary, mushrooms contain polysaccharides that encourage the growth of healthy bacteria in the body by reaching the colon unchanged and providing a source of energy for beneficial bacteria. The stimulation and regulation of the gut microbiome by EMPs have important health implications, contributing to a healthier microbial composition.
