Q: Is gold approved as a food additive in the EU?

A: Yes, Although the gold ion is toxic, the acceptance of metallic gold as a food additive is due to its relative chemical inertness, and resistance to being corroded or transformed into soluble salts by any known chemical process which would be encountered in the human body.

Q: Is gold of pharmacological value, since elemental gold is inert to all chemicals it encounters inside the body?

A: Yes, Some gold salts do have anti-inflammatory properties and at present two are still used as pharmaceuticals in the treatment of arthritis and other similar conditions in the US. These drugs have been explored as a means to help to reduce the pain and swelling of rheumatoid arthritis, and also against tuberculosis and some parasites.

Q: Is gold highly conductive to electricity, and has been used for electrical wiring in some high-energy applications?

A: Yes, For example, gold electrical wires were used during some of the Manhattan Project's atomic experiments, but large high-current silver wires were used in the calutron isotope separator magnets in the project.
