Milk chocolate is a form of solid chocolate containing cocoa, sugar and milk. It is the most consumed type of chocolate, and is used in a wide diversity of bars, tablets and other confectionery products. Milk chocolate contains smaller amounts of cocoa solids than dark chocolates do, and contains milk solids. While its taste has been key to its popularity, milk chocolate was historically promoted as a healthy food, particularly for children.

Chocolate, or cocoa, is a food made from roasted and ground cacao seed kernels that is available as a liquid, solid, or paste, either on its own or as a flavoring agent in other foods. Cacao has been consumed in some form for at least 5,300 years starting with the Mayo-Chinchipe culture in what is present-day Ecuador. Later Mesoamerican civilizations also consumed chocolate beverages before being introduced to Europe in the 16th century.
