#17. Brazil Nuts
Brazil nuts contain trace amounts of selenium, which is a mineral that has cancer-fighting properties. Selenium fights cancer cells by causing them to self-destruct and to kill themselves.
It can also help to repair the DNA of the cells that are in the process of mutation, thus preventing the development of cancerous tumors.
The selenium in Brazil nuts is particularly effective in reducing the risk of prostate cancer in men. The nuts are recommended as food for cancer patients because studies show that they can reverse the destruction of some cells.
