This article outlines the processes undertaken to revise Canada's Food Guide and shares the updated science that underpins the dietary pattern. The Dietary Reference Intakes provide updated nutrient requirement values and better tools for dietary assessment and planning. Alignment with this updated science was an important component of defining and communicating accurate dietary guidance for Canada. Ensuring that stakeholders had access to the updated review of requirements led to the development of the text Dietary Reference Intakes: The Essential Guide to Nutrient Requirements. Equally important was ensuring that stakeholders were provided opportunity to influence the approach taken to giving dietary guidance, both content and the elements of the final package. A combination of research, consultation and expert advice guided the process to the release of Eating Well with Canada's Food Guide (2007).
