Chocolate originated from cocoa beans from the cacao tree in Central and South America. The Aztecs and Mayans drank chocolate as a spicy drink. It was introduced to Europe in the 1600s and became popular as a drink in European courts before being consumed as an eating chocolate. Today, chocolate is one of the most popular foods worldwide. Major chocolate manufacturers include Hershey, Mars, Cadbury, Nestle and Lindt. While chocolate has some health benefits, it also has disadvantages like potential addiction, headaches and obesity.
