Malaysia society is experiencing rapid urbanisation and modernization. A sizeable new middle class has emerged and the traditional ways of life and eating habits of the different ethnic communities are changing. For many years, nutritional surveys have been capturing the transformations of food consumptions. To date a comprehensive survey focusing on the socio-cultural determinants of food habits at the national level have not been reported. The purpose of the Malaysian Food Barometer is to fill this gap. This PPT presents the conceptual framework and the methodologies used to investigate the eating practices and cultural representations on food and eating in a multicultural context.
