  • Latest data on the diet of Canadians from the Canadian Community Health Survey reveals that the diet quality of Canadians needs improvement. Within this paper predictors of diet quality in Canada are identified based on two cross-sectional data sets from the Canadian Food Expenditure Survey. To measure diet quality, the Canadian Healthy Food Diversity (CanHFD)-Index is developed which is based on Food Guide recommendations. Moreover, this paper considers that the Food Guide between survey years has changed when analyzing diet quality. To track changes in demand for diet quality we use “Canada’s Food Guide 1982” to calculate CanHFD-Index for 1984 and 1996. Changes in demand for diet quality according to “Canada’s Food Guide to Healthy Eating 1992” are observed by calculating CanHFDIndex with data from 1984 and 1996. Theoretically, this model is related to Becker’s household production theory and Lancaster’s characteristics approach. Multiple regression results show significant changes in the Canadian demand for food diversity over time. Some of the differences can be traced back to the different versions of the Canada Food Guide. Increasing age, higher income, being female, and high education level are positive predictors of diet quality in 1984 and 1996 among others.
