Chocolate is considered by many to be the greatest food on earth. It originated from cocoa nuts and the first chocolate bar was created in 1876. There are three main types of chocolate - white chocolate which contains no cocoa powder, milk chocolate which is the most popular containing cocoa powder and milk, and dark chocolate which contains less sugar and is more bitter containing only cocoa powder. Popular chocolate makers include Hershey, Nestle, and Ghirardelli. Chocolate is commonly used in cakes, with nuts, filled with caramel, or eaten plain, and is made from cocoa beans, milk, cocoa butter, and sugar. Dark chocolate can provide health benefits while milk chocolate acts as a mood booster.
