It is now believed by nutritional scientists that the metallic elements Silver, Gold, Zinc, Copper as well as other rarer elements like Selenium are essential for our well-being and maintenance of body systems. Like many other minerals, they have always been present in our food but in diminishing amounts in recent decades. For each element there is a minimal daily requirement. In the case of Silver, Selenium, Chromium, Iodine and Molybdenum this is around 100 micrograms (0.1 milligrams). For Zinc it is 100 milligrams. Gold is also likely essential but its requirements are unknown. Without such ultra-trace essential minerals, our ability to resist disease is seriously compromised.
