In India, gold is sprinkled upon sweets making them an expensive delicacy during festive seasons and special occasions.
For the gold to be edible, it must be 23-24 carat and is not the same gold which we find at the jewelers that is mixed with other metals. So, when gold is used in food it has the E-number E175. E-numbers are codes for substances that are permitted to be used as food additives for use within the European Union. Scientifically, gold is chemically inert, which means it just passes through your body as waste and does not break down in digestion.
Gold is also used in medications, especially in a treatment for rheumatism. Some studies also show that it has anti-inflammatory properties. The consumption of gold and its effects on us is still under study, and so one must exercise caution while consuming it. (1, 2)
