Gold is a precious metal that has been valued for its beauty and, in some cultures, its health benefits. In recent years, gold has become a popular food additive in sweets, drinks, and even burgers. Gold is chemically inert and will not react inside the human body, meaning it can be safely consumed. While it has no taste or nutritional value, gold is believed to have health benefits, including anti-inflammatory properties and the ability to boost overall health. The addition of gold to food is primarily for decoration and to add a touch of luxury. Gold leaves and flakes are prepared by hammering and pounding metal sheets until they reach a thickness of 1/8,000 of a millimeter. Gold can be added to a variety of foods and drinks, including chocolates, sweets, fruits, and cocktails.

What You'll Learn
Gold is safe to consume and is gluten-free
Gold is generally considered safe to consume and is sometimes used for medicinal and decorative purposes. The European Food Safety Administration (EFSA) has designated edible gold as E-175, a food additive or colouring agent. According to EFSA, edible gold must be at least 90% pure gold, with the remaining 10% consisting of another safe metal, such as silver.
Edible gold is typically 23 to 24 karats and is hammered into thin sheets or flakes, which are used to decorate foods and beverages. It is important to note that edible gold is not the same as the gold found in jewellery, which may contain other metals that can be toxic if ingested.
While gold is considered safe to consume, it is not easily digestible and does not provide any nutritional value. It is also important to distinguish between edible and non-edible gold to avoid accidental consumption of toxic metals.
Gold has been used in traditional medicines, such as Ayurveda, where it is believed to boost health and cognitive skills when combined with herbs and spices. Some studies also suggest that gold has anti-inflammatory properties and has been used in conjunction with sulphur and phosphor as a delivery system for medications.
Gluten is a protein found in wheat, barley, rye, and triticale. While gold is gluten-free, it is important to ensure that it is consumed safely and in appropriate quantities. As with any food additive, it is always good to practice moderation and consult a healthcare professional if you have any concerns or allergies.

Gold is chemically inert and will not react inside the body
Gold is a chemical element with the symbol Au and atomic number 79. It is a transition metal and one of the least reactive chemical elements. This is due to relativistic effects—gold has a heavy nucleus, causing its electrons to travel at extremely high speeds, which in turn leads to the contraction of its orbitals. As a result, gold is chemically inert and does not react with other substances, including air and water.
This property of gold also means that it is chemically inert inside the human body. The body's digestive system cannot break down gold, and it will simply pass through without being absorbed. Therefore, it is safe to consume gold in the form of food additives such as gold leaves, flakes, dust, or salts. Gold is often added to foods such as sushi, sweets, and cocktails, or to drinks such as champagne.
However, it is important to note that while gold is chemically inert, it can still cause allergic reactions in some individuals. For example, jewellery containing gold can trigger allergic contact dermatitis in people allergic to the metal. Additionally, nanoparticles of gold may affect individuals with hypersensitivity to metals, potentially impacting cell membranes if injected directly.
Despite these potential risks, gold is generally recognised as a safe food additive. It has been used in various culinary and medicinal applications throughout history, including in ancient Indian Ayurvedic medicines and restorative dentistry. Today, gold is used in medical diagnostics, cosmetics, and as a non-toxic control in scientific studies.

Gold is recognised as a food additive by the EU and US
Gold is recognised as a food additive by the European Food Safety Authority (EFSA), which gave gold the E number E175. The EFSA has authorised the use of gold as a food additive at quantum satis in the external coating of confectionery, decoration of chocolates, and in liqueurs. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has not reviewed gold due to a lack of data, and no acceptable daily intake (ADI) has been established.
In the US, gold is recognised as a food additive by the US Food and Drug Administration (USFDA), which considers it a gourmet food and drink product. Gold is also recognised as a kosher food additive by the Federation of Synagogues, making it suitable for consumption by Jewish people.
Gold has been used as a decorative food and beverage garnish for centuries, dating back to ancient Egypt and the Middle Ages in Europe. It was also used in medicine by court physicians in Japan, China, and India. In modern times, gold has been added to foods such as sushi, sweets, cakes, cocktails, and wines, as well as to expensive treats like burgers and steaks.
The purity of edible gold is typically 22 to 24 karats, and it is chemically inert, meaning it will not react inside the human body. While some believe that gold has health benefits, such as reducing inflammation and improving cognitive skills, others argue that it does not provide any nutritional value and is only good as a food additive for a touch of sophistication.

Gold is a popular additive to food and drinks, especially as a decorative element. Gold leaves and flakes are usually prepared by gold hammering and pounding metal sheets repeatedly until they reach 1/8,000 of a millimeter in thickness. Gold is also gluten-free and widely recognised as a food additive with an E number of E175.
Gold has been used in dentistry and medicine, as well as a food decor ingredient, since ancient times. Its inertness, malleability, and similarity in hardness to natural teeth make it a suitable material for dental work, and its perceived health benefits and decorative appeal make it a popular food additive.
