Brain cancer is associated with physical and cognitive disruptions, and many patients die within a few years. Compared with other cancers, the development of brain cancer is more complex and there has been focus on underlying causes such as head traumas, allergies, and electromagnetic radiation from cell phones, transmission towers, etc. Scientists have also looked at vitamins and brain health, whereas minerals have been ignored. Now, a team of Chinese scientists have conducted a large population study and found that higher intake of calcium, magnesium, iron, zinc, and copper is linked to a reduced risk of different types of brain cancer (gliomas). Apparently, selenium also has a protective effect.
