Food has the primary and vital functions of satisfying people's biological and hedonic needs. However, food reflects other complex meanings, such as a national and cultural identity, and can be a key factor in different contexts, such as entertainment, associations, and in getting acquainted with regional cultures. Moreover, changing behavioural patterns and lifestyles, and increasing consumer concerns for health emphasize the "back to tradition" and, back to nature" type of food. Contrary to the globalization of food, which has affected people's eating behaviour since the late-1960s, support for traditional, regional cuisine and indigenous country food has become more fashionable. Additionally, food plays a key role in attracting tourists to a certain destination because of its reflection of a region's culture and lifestyle. Having in mind that there is a vast amount of literature on food and its functions, this eBook seeks to extend the insights into the resurgence of traditional and authentic food.
