You can eat pure 24-karat gold because it never dissolves in your stomach.

Gold is chemically 'lazy' and refuses to bond with other elements. This makes it a noble metal that resists rust and corrosion. Even the strong hydrochloric acid in your stomach, which has a very low pH of 1.5 to 3.5, cannot break it down. Because it stays exactly the same, the European Union officially labels it as a food additive called E175.To be safe to eat, the gold must be 24-karat, which is 99.9% pure. Cheaper gold often has other metals like copper mixed in, which can be bad for your health. Edible gold is hammered into incredibly thin sheets called gold leaf. These sheets are about 0.12 microns thick, which is 500 times thinner than a single strand of human hair. This makes the metal soft enough to swallow without feeling any sharp edges.People have been eating gold for a long time. In the Middle Ages, some people thought it was a medicine that could heal the body. Today, it is mostly used for decoration in fancy restaurants. In 2010, a restaurant in New York City called Serendipity 3 sold a chocolate dessert for $25,000 because it was covered in five grams of gold. Even though it looks expensive, gold has no taste, no calories, and no vitamins.
