The time for an updated Canadian Food Guide has arrived.

Canada has published food guides since 1942 and the latest version, Eating Well with Canada's Food Guide (EWCFG), was released in 2007. The EWCFG is largely based on meeting nutrient requirements, while we are now in need of a food guide with strong guidance on the role of diet in the prevention of chronic diseases. This article systematically analyses the process and assumptions behind the EWCFG and presents suggestions for needed revisions to the next food guide. [ABSTRACT FROM AUTHOR]
