Gold is one of the most popular metals used in jewelry. It is also very useful in electronics. In addition to its more common uses, gold is used as a food additive – usually for decorative purposes in the form of gold leaf (E number E175). It is quite popular as an additive to alcoholic drinks and there is a traditional Polish and German liqueur called Goldwasser (Goldwater) which contains thousands of tiny flakes. Gold is inert to body chemistry so it passes through the body unaltered and has no nutritional value.
