Can we eat gold?
Gold is a noble metal and for this reason it does not react inside human bodies. This means that it is not absorbed during the digestion process, so it is safe to eat. Purity of edible gold must be 23–24 karats, above that used in typical jewelry, which may contain other metals and can be toxic if consumed.

What is the most abundant metal in the human body?
It’s also the most abundant metal in the human body, found both in ionic form (necessary for physiological and biochemical processes) and in its more familiar bones and teeth form as hydroxyapatite—the mineral form of calcium that comprises 70 percent of the weight of our bones and a significant amount of our teeth.
Is the human body made up of metals?
Our body is composed of almost every natural element found in nature. This is as true for metals as it is for water or carbon.
What elements make up the majority of the human body?
