Mushrooms: Cancer-Fighting Superfood?

Mushrooms have been used for medicinal purposes for a long time, especially in Asian countries. In recent years, their use for treating diseases, including cancer, has increased in other parts of the world. While there is currently no evidence that mushrooms can prevent or cure cancer, research has shown that higher mushroom consumption is associated with a lower risk of cancer. Mushrooms are rich in vitamins, nutrients, and antioxidants, which protect cells from damage that can cause cancer. In addition, mushroom-derived compounds have been found to exert antitumor and antimetastatic effects by affecting various molecules in the PI3K/AKT pathway. Furthermore, studies have shown that consuming mushrooms alongside standard cancer treatment may improve outcomes.

Mushrooms are rich in vitamins, nutrients, antioxidants and fiber

Mushrooms are rich in vitamins, nutrients, antioxidants, and fiber. They have been used medicinally for a long time, especially in Asian countries. Mushrooms are a good source of ergothioneine, a unique and potent antioxidant that protects cells from damage that can cause cancer. They are also a source of beta-glucans, a soluble fiber that can boost the immune system and help the body fight cancer.

Vitamin D, which is also found in mushrooms, has been reported to have anti-cancer properties against many cancer types, including breast cancer. White button mushrooms, in particular, have shown efficacy in prostate cancer research. In addition, a review of five studies found that patients who were given Ganoderma lucidum (also known as reishi mushrooms) alongside standard cancer treatment were more likely to respond positively compared to chemo/radiotherapy alone.

Research by Pennsylvania State University found that people who eat two mushrooms a day (around 18 grams) have a 45% lower risk of cancer compared to those who do not eat mushrooms. However, it is important to note that this research was a meta-analysis, and further studies are needed to pinpoint the specific cancers that may be impacted by mushroom consumption.

While the findings suggest that mushrooms may help lower the risk of cancer, it is important to remember that a healthy diet involves a variety of foods and that no single food or drink is likely to be the sole cause or prevention of cancer.

Mushrooms may lower the risk of breast cancer

Mushrooms have been used for medicinal purposes for a long time, especially in Asian countries. In recent times, their use for treating a number of diseases, including cancers, has increased in other parts of the world.

A study by Penn State College of Medicine researchers found that higher mushroom consumption is associated with a lower risk of cancer. The study, published in Advances in Nutrition, examined 17 cancer studies published from 1966 to 2020. It analyzed data from more than 19,500 cancer patients and explored the relationship between mushroom consumption and cancer risk. The findings showed that individuals who ate 18 grams of mushrooms daily had a 45% lower risk of cancer compared to those who did not eat mushrooms. Mushrooms are rich in vitamins, nutrients, and antioxidants, which may help protect against cancer.

When specific cancers were examined, the researchers found the strongest associations for breast cancer. This could be because most of the studies did not include other forms of cancer. Mushrooms are a good source of ergothioneine, an amino acid and potent antioxidant that can protect cells from damage that can lead to cancer. Beta-glucans, a soluble fiber found in mushrooms, can also boost the immune system and may help the body fight cancer.

While the research provides important evidence for the protective effects of mushrooms against cancer, further studies are needed to pinpoint the specific mechanisms involved and the impact on different types of cancer. It is important to note that dietary patterns and other factors also play a role in cancer risk, and it is unlikely that any single food or drink causes or prevents cancer.

Currently, research is being conducted to evaluate the effects of white button mushroom supplementation on inflammation and immune cells in postmenopausal women who are identified as obese and at high risk of developing breast cancer. The findings from this research will provide valuable insights into the potential of mushrooms as a dietary strategy for breast cancer prevention.

Mushrooms may help overcome multidrug resistance (MDR)

Additionally, certain mushrooms can increase the cytotoxicity of specific anticancer drugs. For example, Cantharellus cibarius (M02) and Russula emetica (M12) enhance the effectiveness of paclitaxel (TAX) and doxorubicin by blocking Pgp-mediated drug efflux in certain cancer cells. Ganoderma lucidum polysaccharide (PLP) inhibits the expression of Pgp in cancer cells, and compounds isolated from Taiwanofungus camphoratus have been found to reverse drug resistance against doxorubicin, vincristine, and paclitaxel.

Hispolon, a polyphenol compound found in mushrooms, has been reported to enhance the cytotoxicity of chemotherapeutic agents, suggesting that mushrooms may act synergistically with commercial anticancer drugs to treat drug-resistant cancers. Furthermore, nanomaterials such as gold nanoparticles (AuNPs) have been shown to improve the anticancer activity of drugs in MDR cancer cells, providing another potential strategy for overcoming MDR.

While the medicinal use of mushrooms has been prevalent in Asian countries for a long time, their use in treating cancers has gained traction in other parts of the world. The therapeutic potential of edible and medicinal mushrooms is attributed to the presence of bioactive substances. However, further research is needed to fully understand the molecular mechanisms underlying cancer development and the specific targets of mushroom-derived compounds.

Mushrooms can boost the immune system

Mushrooms have been used medicinally for a long time, especially in Asian countries. In recent years, their use in treating various diseases, including cancer, has increased in other parts of the world.

Mushrooms are rich in vitamins, nutrients, and antioxidants, which may help protect the body from damage that can lead to cancer. They are also a good source of fiber, vitamins, and minerals. One of the antioxidants found in mushrooms is ergothioneine, a potent antioxidant and cellular protector. Beta-glucans, a soluble fiber found in mushrooms, can boost the immune system and may help the body fight cancer, infection, or other diseases.

Research has shown that higher mushroom consumption is associated with a lower risk of cancer. A study by Penn State College of Medicine found that individuals who ate 18 grams of mushrooms daily had a 45% lower risk of cancer compared to those who did not eat mushrooms. The researchers noted the strongest associations for breast cancer, but the study did not include other forms of cancer.

While the research is promising, it is important to note that a single research paper does not prove anything on its own. More studies are needed to pinpoint the mechanisms involved and specific cancers that may be impacted. Additionally, experts believe that it is not just a single food or drink that causes or prevents cancer, but rather the patterns of what we eat across our lives that lower or increase our risk.

Some specific types of mushrooms that have been studied for their potential health benefits include shiitake, oyster, maitake, and king oyster mushrooms. White button mushrooms have been studied for their potential in prostate cancer research and are currently being investigated as a dietary strategy for the prevention of breast cancer. Reishi mushrooms, also known as Ganoderma lucidum, have been found to have many reported benefits, including enhancing the immune system and treating cancer. A review of five studies found that patients who were given reishi mushrooms alongside standard cancer treatment were more likely to respond positively compared to those who received treatment alone.

Mushrooms have been used medicinally for a long time in Asia

Mushrooms have been used for medicinal purposes for a long time in Asia. In fact, the use of mushrooms for promoting and maintaining a good state of health and the treatment of diseases has been around since ancient times in Asian regions. In China, mushrooms like shiitake, which is known as the "elixir of life", and Cordyceps have been used as medicine for hundreds of years. Cordyceps, a parasitic fungus that preys on insects, is used as a powerful tonic to improve energy, appetite, stamina, and endurance.

In traditional Chinese medicine, Coriolus versicolor, commonly known as turkey tail, has been used as a "magic herb" to promote good health, strength, and longevity. Ancient formulations based on this mushroom have been widely used in China for thousands of years, and extracts of this mushroom have been approved for clinical use in China since 1987 and in Japan since 1977. Turkey tail is also used in Japan to strengthen the immune system when given with standard cancer treatment.

Shiitake mushrooms, which have been cultivated in Japan for centuries, are thought to support a long, healthy life and healthy circulation. They have been shown to increase IgA, a key immune cell associated with the body's first line of defence, and decrease C-reactive protein, a blood marker that detects inflammation. Lion's Mane, or Hericium erinaceus, is another type of mushroom used in traditional Chinese medicine to aid with digestion, energy, and water regulation.

Medicinal mushrooms have been approved as an addition to standard cancer treatments in Japan and China for more than 30 years. In these countries, mushrooms have been used safely for a long time, either alone or in combination with radiation or chemotherapy. In Asia, there are more than 100 types of mushrooms used to treat cancer, including Ganoderma lucidum (reishi), Trametes versicolor or Coriolus versicolor (turkey tail), Lentinus edodes (shiitake), and Grifola frondosa (maitake).

While the use of mushrooms in medicine is ancient and deep-rooted in Asia, it is still a complex field, and more research is needed to fully understand the mechanisms involved and the specific cancers that may be impacted.
