Top dietary sources of energy, sodium, sugars, and saturated fats among Canadians: insights from the 2015 Canadian Community Health Survey

Dietary factors are major contributors to morbidity and mortality, and significant attention is being paid to interventions to support healthy eating, including through the creation of a healthier food supply. The objective of this study was to inform interventions to support healthy eating by examining the top dietary sources of calories, sodium, sugars, and saturated fats among Canadians in relation to sex, age, and income. We drew upon data from the 2015 Canadian Community Health Survey, which collected interviewer-administered 24-h dietary recalls from Canadians who were 1 year of age and older (n = 20176), residing in the 10 provinces. Foods and beverages were grouped into 91 mutually exclusive categories (e.g., 100% fruit juice, fruit drinks). On the basis of the average proportion contributed, the top 20 sources of each dietary component were identified for all individuals and by sex-age and income groups. The mean amount of each dietary component contributed by each category (per capita and per consumer) and the proportions of persons consuming items in each category were also examined. Top sources included commonly consumed items (e.g., breads and flatbreads as sources of sodium), as well as those high in a given dietary component (e.g., soda as a source of sugars). Several food and beverage categories were top contributors to more than one dietary component examined, suggesting possible priorities for intervention and future analyses. The identification of major sources of calories and nutrients of concern can inform population health efforts, such as reformulation, to improve the health of Canadians.
