Indeed, Cancer Research UK says that experts think that nearly one in 20 UK cancer cases could be prevented through healthy diets. This may partially be because a balanced diet can help maintain healthy body weight. There are also certain foods that are lauded for cancer-reducing properties, though the charity warns “it is unlikely that any single food will make much of a difference on its own” and advises that people instead adopt a healthy, balanced diet.

One food that may be consumed as part of a healthy diet is reishi mushrooms, which can be consumed as tea.

Healthline notes that many people consume this fungus “due to its potential cancer-reducing properties”.

It cites one study of more than 4,000 breast cancer survivors, which found that around 59 percent consumed reishi mushrooms. It adds: “Additionally, several test-tube studies have shown that it can lead to the death of cancer cells.”

Healthline also notes that reishi mushrooms have been studied for their role in preventing or fighting colorectal cancer.

The site says: “Some research showed that one year of treatment with reishi decreased the number and size of tumors in the large intestine. What’s more, a detailed report of multiple studies indicated that the mushroom can beneficially affect cancer patients.

“These benefits included increasing the activity of the body’s white blood cells, which help fight cancer, and improving quality of life in cancer patients.”

Nonetheless, researchers emphasize that reishi mushrooms should be administered in combination with traditional treatment rather than replacing it.

Healthline also warns that many of the studies of reishi mushroom and cancer “were not high-quality” and because of this, much more research is needed.

It summarises: “Although reishi mushroom appears to hold some promise for cancer prevention or treatment, more information is needed before it becomes part of standard therapy. Read more: https://bit.ly/3wgdD58
