New study throws light on the differences in diet quality between people of lower and higher socioeconomic status in Canada. The study suggests that lower-income Canadians may tend to buy unhealthy foods which are low in cost and have poor diets. This increases the need for implementing certain effective nutrition policies to improve nutrition and reduce dietary inequities.
To address the root causes of poor diets, improve nutrition and reduce dietary inequities in Canada requires a broad approach, combining nutrition and social policies, argues an analysis in CMAJ (Canadian Medical Association Journal).
‘Dietary Inequities in Canada: People with lower socioeconomic status in Canada are more likely to have poor diets. Existing nutrition policies such as putting nutrition facts tables and warning labels on packaged foods may not be as effective in improving diet. Lower-income Canadians may still purchase unhealthy foods with warning labels because of a lower cost if healthier options are unaffordable.’
Dietary inequities refer to differences in diet quality between people of lower and higher socioeconomic status. For example, people with a lower socioeconomic status tend to have poorer quality diets, eating fewer fresh fruits and vegetables, than people with a higher socioeconomic status.
Canada's nutrition policies, such as putting nutrition facts tables on packaged foods, Canada's Food Guide and the recent Healthy Eating Strategy, mainly provide information and do little to address the underlying causes of unhealthy eating. Existing policies may not be as effective in improving diet as they could be.
"Such policies are unlikely to substantially improve diet quality in Canada, particularly among individuals with a lower social position, because they do not address the root causes of poor diet quality in daily life," says Dr. Dana Lee Olstad, Department of Community Health Sciences, University of Calgary, Alberta. "For example, even if warning labels are put on unhealthy foods, lower-income Canadians may still purchase them because of lower cost if healthier options are unaffordable."
Partnerships are needed between government ministries responsible for health, Indigenous affairs, housing, taxation, and others to implement policies that address nutrition, along with the social determinants of health.
"[W]e propose that the next phase of action to improve the quality of Canadians' diets should concentrate on partnerships with nonhealth actors on bold policy measures to address the social determinants of health, along with equity-oriented nutrition policies. Some of the most powerful policies will be those that improve economic security, reduce precarious employment and ensure access to postsecondary education regardless of ability to pay," writes Dr. Olstad with coauthors.
By doing this, say the authors, Canada can reprise its role as a world leader in health promotion.
