Researchers are today acknowledging the significance of considering food processing in epidemiological and nutritional studies to prevent chronic diseases. Yet, in most countries, food processing is not considered in food classification systems. A Brazilian research team has recently introduced a new classification system in which foodstuffs are groups based on the intensity, the nature and purpose of food processing. This classification was used to study time trends in consumption of ultra processed foods in Brazil and to discuss likely impacts for human health. The main objective of this research project is to develop an international comparative study to assess time trends in food consumption according to the new classification system. To do so, a replication study will be carried out with data collected in Canada using the novel approach and methodology described by the Brazilian team. In a first step, the new classification will be compared and discussed relative to the Canadian food classification system. It will then be used to assess time trends in consumption of processed foods in Canada using the Canadian Food Expenditure Surveys (FES), and to establish comparison with the Brazilian data. Finally, we will review the sources of national household data available for other countries than Brazil and Canada and we will prepare another project to expand the comparison with other countries. Overall, this project will last one year including data processing, analysis, preparation of papers, dissemination of results and the establishment of a research collaborating network. This project will help to increase awareness on the importance of food processing in nutritional and epidemiological studies. It will provide the first international comparison study of time trends in consumption of processed foods and will shed light on the contribution of nutritional factors to the current pandemic of chronic diseases.
