Chocolate has a rich history dating back thousands of years. Cacao was first cultivated by the Olmecs in Mesoamerica over 5000 years ago. Later, it was so valued by the Mayan and Aztec peoples that they used cacao beans as currency and in sacred rituals. It was also prepared as a bitter beverage reserved for royalty and warriors. In the sixteenth century, European explorers brought cacao back to Europe, where sugar and milk were added to make it more palatable, but it remained a delicacy only available to the elite. Over time, with industrial advances, chocolate became widely obtainable around the world. Today almost two-thirds of global consumers purchase chocolate at least once a year and over half of them eat it at least once a week.
Contemporary chocolate comes in several varieties, each with its own distinct taste and texture. Dark chocolate has the highest percentage of cocoa solids and little to no milk giving it a rich, slightly bitter flavor. Milk chocolate, the most popular type, contains cocoa solids, milk, and sugar, giving it a smooth and creamy texture. White chocolate, despite its name, contains no cocoa solids but only cocoa butter, sugar, and milk that together result in a sweet, buttery flavor. In 2017 a Belgian–Swiss cocoa company introduced ruby chocolate, a pink chocolate with a slightly sweet and sour taste also made from cocoa solids, milk, and sugar, but also citric acid. The color comes from the kind of cocoa used and there is still debate about whether or not this truly is a fourth kind of chocolate.
Whatever the kind, chocolate is incredibly popular. Surveys reveal that the number one reason people eat chocolate is because it tastes good, but they also eat it to make themselves happy, enjoy a special treat, reward themselves, or relax. Researchers have found, however, that it is not just the taste of chocolate but also the texture that is enjoyable, particularly the sensation of chocolate melting in the mouth. Other research suggests that the enjoyment in eating chocolate comes from some of the compounds in chocolate that can influence the reward and pleasure centers of the brain. However, chocolate may not contain enough of these to have much of an effect on mood. Still other research indicates the sugar to fat ratio is key, particularly with milk chocolate. Because it is the same as breast milk, humans might be in a sense hardwired to like chocolate.
Despite all the joy chocolate can bring, the chocolate industry faces several ethical and environmental controversies. One major issue is child labor, particularly in West African countries like Ghana and Côte d’Ivoire, where children work under harsh conditions on cocoa farms, often missing out on education. Additionally, many cocoa farmers receive extremely low wages, while large corporations profit significantly. Environmental concerns also arise, as cocoa farming contributes to deforestation.
So as we celebrate National Chocolate Lover’s Month, let us also remember the importance of sustainable and ethical sourcing. Supporting brands that prioritize fair trade and environmentally friendly practices ensures that cocoa farmers receive fair wages, and that chocolate production remains sustainable for future generations.
