What You'll Learn
Cancer-fighting properties
Maitake mushrooms, scientifically known as Grifola frondosa, are edible mushrooms prevalent in northeastern Japan and China. They are an important component of Asian cuisine and have been used in traditional medicine for centuries.
Maitake mushrooms contain beta-glucan, a compound that may possess skin-benefiting properties. Laboratory and mouse research has shown that extracts of the mushroom may help reduce symptoms of atopic dermatitis (eczema). Maitake mushrooms also contain antioxidants like fatty acids and polyphenols that may improve skin health.
Maitake mushrooms have been studied for their potential anticancer effects. Various studies suggest that maitake mushrooms may help the body fight cancer cells through three pathways: protecting healthy cells, preventing tumour spread, and inhibiting growth. The D-fraction extract of maitake mushrooms has shown promise in reducing tumour size and improving outcomes for different cancers. This extract acts as a biologic response modifier, providing T-cell-dependent immune enhancement and activation, which enhances its antitumor effect.
Maitake polysaccharides have been found to induce apoptosis (programmed cell death) in human breast cancer cells via the mitochondrial-dependent apoptotic pathway. The antitumor effects of beta glucan GFPBW1 are believed to be exerted through the Dectin-1/Syk/NF-κB signalling pathway. Orally administered maitake alpha-glucan has been shown to activate dendritic cells and macrophages in the small intestine, resulting in the induction of a systemic antitumor T-cell response.
While maitake mushrooms show potential in fighting cancer, more clinical research on people living with cancer is needed to understand whether the mushroom could be used as part of any type of cancer treatment.

Diabetes and blood sugar regulation
Maitake mushrooms, also known as "dancing mushrooms" in Japanese, have been revered for their medicinal properties for centuries. Recent studies have explored the potential benefits of these mushrooms in managing diabetes and blood sugar levels.
Several studies have indicated that maitake mushrooms contain unique polysaccharides, specifically beta-glucans, which can mimic insulin's action, improving insulin sensitivity and promoting the uptake of glucose into cells. This mechanism helps enhance blood sugar control, making it a potential natural tool for managing insulin resistance. Additionally, beta-glucans can modulate gut microbiota, promoting a healthier balance of gut bacteria that positively influences blood sugar regulation.
The maitake mushroom's ability to influence blood sugar levels has been observed in animal studies. Research on rats with type 1 and type 2 diabetes has shown positive results in managing blood sugar levels. A water-soluble extract of maitake mushroom, known as Fraction X (FXM), significantly lowered circulating glucose concentrations in insulin-resistant KK mice. This extract also improved glucose intolerance in obese mice.
However, it is important to note that the majority of research on maitake mushrooms and blood sugar regulation has been conducted on animals, and more human-based studies are needed to verify these findings. While maitake mushrooms show potential in blood sugar management, consulting a healthcare professional is crucial before incorporating them into a diabetic treatment plan. Additionally, those already taking insulin should avoid maitake supplements due to the risk of flooding the body with excess insulin.
Overall, while maitake mushrooms have shown promise in managing diabetes and blood sugar levels, further research is needed to confirm their efficacy and safety for human use.

Anti-inflammatory effects
Maitake mushrooms (Grifola frondosa) are edible and medicinal fungi that grow wild in Japan, China, and North America. They have been used in traditional medicine, especially in Japan and China, for their immune-boosting, blood sugar regulation, and overall health-promoting properties.
Maitake mushrooms have significant anti-inflammatory properties, which can help reduce inflammation and support overall health. The beta-glucans in maitake mushrooms have been shown to have anti-inflammatory effects, specifically by inhibiting cyclooxygenase (COX) enzymes, which play a role in inflammation. In laboratory studies, maitake mushrooms have also been found to inhibit additional pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-1B.
The anti-inflammatory capabilities of maitake mushrooms have been demonstrated in laboratory research, but human studies are still necessary to confirm these effects. The polysaccharides present in maitake mushrooms, including beta-glucans, have also been found to have anti-inflammatory effects, in addition to their antitumor, antioxidant, antidiabetic, and immunomodulatory properties.
The potential health benefits of maitake mushrooms extend beyond their anti-inflammatory properties. They are also known for their ability to stimulate the immune system, improve insulin sensitivity, reduce insulin resistance, and lower cholesterol levels. Additionally, maitake mushrooms have been studied for their potential antitumor and anti-cancer effects, as well as their ability to improve heart health by reducing the risk of cardiovascular disease.
While maitake mushrooms offer a range of potential health benefits, it is important to consult a healthcare professional before incorporating them into your diet or using them as a supplement.
