Gold is a metallic yellow transition
metal and belongs to the copper group, as does copper and other precious metals
such as silver. In chemistry, these three metals are also referred to as
“coin metals”. In addition to ritual use as jewelry or means of
payment, gold is also used as an additive in food as E175. It is used in
medicine, electronics, optics, decoration or as a food additive and still has
the function of an investment and a currency. The consumption of gold in small
amounts in food e.g. as a decoration is harmless, since it is insoluble in
gastric acid and is excreted.
