Safety of edible gold

Traditional Chinese medicine divides gold into "raw gold" and "cooked gold", and gold that has not been smelted and forged many times is called raw gold, which is "toxic and can kill people, and should not be used as medicine";

Because the impurities in raw gold have not been removed, it is correct from a scientific point of view. The gold foil with purity above 91% is safe to eat. Relatively speaking, the lower the purity of gold foil, the more heavy metal components such as lead and copper are mixed in it, which makes it unsuitable for eating.

and it will cause heavy metal poisoning. In 1983, the World Health Organization listed gold as a food additive. Because the quality of gold foil is light, less than 2 grams of gold is used in a golden feast;

Therefore, some gold foils, such as gold foil meat buns, gold foil coffee and gold foil cakes, are eaten in a very small amount, and the gold foils with high purity (above 91%) will be excreted in about 24 hours after eating, and will not accumulate in the body, so it is safe to eat.
