The 2004 Canadian Community Health Survey (CCHS) revealed many indicators of poor diet quality in Canada which, together with the high rates of obesity and diet-related chronic disease, suggest that shifts in dietary patterns are urgently needed. Given the widespread promotion of foods on the basis of nutrition and health, the aim of this work was to explore the population health implications of voluntary food fortification and nutrition-related marketing in Canada.
Using the CCHS, the potential impact of a proposed discretionary food fortification policy on nutrient inadequacies and excesses was examined, in addition to the relationship between consumption of foods eligible to be fortified under this policy and indicators of dietary quality. To better understand the potential risk associated with liberal fortification practices, the National Health and Nutrition Examination Survey (2007-08) was used to examine potential for risk of excess associated with voluntarily fortified food consumption in the US, where these practices have long been permitted. The results suggest that proposed changes to voluntary fortification may reduce inadequacy and increase excess, and may reinforce poor diet patterns. Excessive nutrient intakes were also found to be associated with consumption of voluntarily fortified foods in the US, particularly among children. Therefore, there appears to be real potential for risk associated with voluntary fortification practices in Canada.
The extent, nature, and population health implications of nutrition marketing in Canada was examined, using a survey of front-of-package nutrition-related marketing on foods within three large grocery stores in Toronto. Nutrition-related marketing was found on 41% of all foods surveyed, and was widely found on highly processed, often fortified foods. References to nutrients of public health concern (e.g. sodium, vitamin D) were infrequently found. Overall, this practice provides limited nutritional guidance.
Current directions in nutrition policy in Canada should be re-evaluated, to ensure that they support healthy diet patterns.
