Mushrooms are a fun ingredient to cook with and are enjoyed by many people around the world. They are rich in vitamins, nutrients, and antioxidants. Bioactive compounds are also present in mushrooms. However, there is an ongoing debate about whether mushrooms cause cancer. While some studies have found a positive association between mushroom consumption and lung cancer, others suggest that eating mushrooms may help protect against cancer. So, do mushrooms cause cancer, or do they help prevent it?

Mushrooms are rich in vitamins, nutrients, and antioxidants
Mushrooms are a rich source of vitamins, nutrients, and antioxidants. They are low in calories and sugar, and contain fibre, minerals, and vitamins B, D, and K. Mushrooms also contain riboflavin, niacin, selenium, and potassium. Selenium helps prevent cell damage, while vitamin D helps with cell growth and absorption of calcium for bone health. Potassium is known to reduce the negative impact of sodium on the body, thereby lowering blood pressure.
Mushrooms are also a good source of ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage. Choline, another antioxidant in mushrooms, is believed to reduce the risk of certain types of cancer. However, one study indicated that it may increase the risk of lethal prostate cancer.
Some mushroom varieties, such as shiitake, oyster, maitake, and king oyster, have higher amounts of ergothioneine. Cremini mushrooms are an excellent source of zinc, an essential nutrient for the immune system and optimal growth in infants and children. Lion's mane mushrooms contain two compounds, hericenones and erinacines, that stimulate the growth of brain cells.
While the specific mechanisms are still being studied, research suggests that consuming mushrooms may lower the risk of certain types of cancer.

Consumption may be associated with a lower risk of breast cancer
Mushrooms are generally known to be a healthy food and are widely consumed in many countries. They are low in fat and sugar and contain fibre, minerals such as potassium, and vitamins B and D. They also contain riboflavin, niacin, vitamin D, selenium, potassium, and bioactive compounds.
Recent studies have found that mushroom consumption may be associated with a reduced risk of certain cancers. A study by Pennsylvania State University found that people who eat two mushrooms a day (around 18 grams) had a 45% lower risk of cancer compared with those who did not eat mushrooms. The study looked at 17 cancer studies from 1966 to 2020 and analysed more than 19,500 people who developed cancer.
Several retrospective case-control studies have also reported that high mushroom consumption may be associated with a lower risk of breast cancer. A prospective cohort study included 68,327 women and 44,664 men who were free of cancer at baseline. During up to 26 years of follow-up, the researchers documented 22,469 incident cancer cases.
However, it is important to note that retrospective case-control studies are prone to selection and recall biases, and the existing evidence is largely from relatively small studies from Asian countries. More prospective studies are needed to better understand the role of mushroom consumption in the development of cancers.
While the findings provide important evidence for the potential protective effects of mushrooms against cancer, further studies are needed to pinpoint the specific mechanisms involved and the types of cancers that may be impacted.

Agaricus bisporus and Gyromitra esculenta mushrooms may induce cancer
Mushrooms are generally considered healthy and are widely consumed in many countries. They contain important nutrients such as riboflavin, niacin, vitamin D, fiber, selenium, potassium, and bioactive compounds. However, some mushrooms can be toxic and even carcinogenic.
The Agaricus bisporus mushroom, for example, has been the subject of assessments focusing on the concentrations of certain chemicals it contains and their cancer-inducing properties. These assessments have found that the Agaricus bisporus mushroom contains cancer-inducing doses of certain chemicals, particularly when used in animal experiments. It is important to note that these assessments are tentative and subject to further adjustment due to data limitations.
Gyromitra esculenta, also known as the false morel, is another mushroom that has been linked to potential carcinogenic effects. While it has not been directly observed to cause cancer in humans, it contains compounds such as monomethylhydrazine, gyromitrin, and N-methyl-N-formylhydrazine, which have been shown to be carcinogenic in experimental animals. Even small amounts of these compounds may have a carcinogenic effect. Proper preparation techniques, such as parboiling, are recommended to reduce the toxicity of this mushroom before consumption.
In summary, while Agaricus bisporus and Gyromitra esculenta mushrooms may have potential cancer-inducing properties, the existing research is limited and tentative. Further studies are needed to fully understand their carcinogenic potency and the impact of consumption on human health. In the meantime, it is advisable to exercise caution and follow recommended preparation techniques when consuming these mushrooms.

Agaricus mushrooms are popular in Japan
Mushrooms are generally known as a healthy food and are widely consumed in many countries. They contain many important nutrients, including riboflavin, niacin, vitamin D, fibre, selenium, potassium, and bioactive compounds. Laboratory studies have shown some evidence that mushrooms may be associated with a reduced risk of certain cancers. However, the existing evidence is largely from relatively small studies, and more research is needed to understand the role of mushroom consumption in cancer development fully.
Agaricus mushrooms are indeed popular in Japan, where they are known as "kinoko". While there are many varieties of mushrooms consumed in Japan, Agaricus mushrooms, or shiitake, are among the most popular. They are available fresh or dried, with the latter needing to be soaked in water before use. Shiitake mushrooms are versatile and can be used in various dishes, including nabe (hot pot), boiled dishes, tempura, sukiyaki, soups, and stir-fries. They have a distinctive smoky flavour and are packed with healthy nutrients, including vitamin D, which helps the body absorb calcium.
Shiitake mushrooms have been a part of Japanese cuisine for a long time, with records suggesting that Japanese farmers began cultivating them around 300 years ago using small logs specially prepared with spores of the fungus. An improved version of this bed-log cultivation method is still used today, along with modern farming methods like growing rooms with controlled environments. Shiitake mushrooms are also widely known outside of Japan and are valued for their flavour, fragrance, and nutritional benefits.
Another popular variety of mushroom in Japan is maitake, also known as "dancing mushrooms." These mushrooms have a strong, earthy, and spicy flavour and a soft texture without the usual squeakiness of other mushrooms. They are typically sautéed and are found in Japanese hardwood forests and other parts of the world, including China, Europe, and North America. Matsutake mushrooms are also highly prized in Japan, famous for their characteristic spiciness and aroma. They are challenging to find as they require a very specific type of forest and terrain to grow, typically near pine trees.
Eringi, or king trumpet oyster mushrooms, are also popular in Japan, known for their thick stems and small, flat caps. The flesh is firm with a savoury flavour, and the texture when cooked is similar to abalone and other seafood, making them a popular main or side dish. Enokitake, or velvet shank mushrooms, are another variety cultivated in Japan, known for their white colour and slender stems. They have a crisp texture and are used in various Japanese, Chinese, and Korean dishes.

More research is needed to understand the link between mushrooms and cancer
While there is research to suggest that mushrooms may be linked to a reduced risk of cancer, more research is needed to fully understand this potential relationship.
A study by Pennsylvania State University found that people who ate two mushrooms per day (around 18 grams) had a 45% lower risk of cancer compared to those who did not consume mushrooms. This research, published in Advances in Nutrition, reviewed 17 cancer studies from 1966 to 2020 and analysed data from over 19,500 cancer patients. However, as John Richie, a co-author of the research paper, noted, single research papers do not necessarily prove anything on their own. Further studies are needed to better understand the mechanisms involved and the specific cancers that may be impacted.
Additionally, several case-control studies have reported that mushroom consumption may be associated with a reduced risk of certain cancers, particularly breast cancer. However, these types of studies are prone to selection and recall biases, and the existing evidence is largely from relatively small studies in Asian countries. Larger, prospective studies in diverse populations are needed to confirm these findings and understand the potential role of mushroom consumption in cancer development.
While mushrooms are generally known as a healthy food and are rich in nutrients and antioxidants, there is also some research suggesting that certain chemicals and toxins in mushrooms may be associated with cancer induction. For example, Agaricus bisporus and Gyromitra esculenta mushrooms have been studied for their potential links to cancer. Additionally, agaritine, an amino acid found in commercial mushrooms, has been associated with rapid cancer development. However, these findings may not directly translate to humans, as one study noted that the amount of mushrooms required to induce cancer in mice would be extremely high for humans. More research is needed to understand the effect of mushroom consumption on cancer risk in humans.
In conclusion, while there is some promising research suggesting a potential link between mushroom consumption and a reduced risk of cancer, more comprehensive and diverse studies are needed to confirm these findings and fully understand the relationship between mushrooms and cancer.
