Canadian dietary habits have evolved, with ultra-processed foods (UPFs) becoming increasingly common, raising public health concerns. Canada has a high consumption rate of these products.
What are ultra-processed foods (UPFs)?
The NOVA classification system helps distinguish different levels of food processing:
- Unprocessed or minimally processed foods: Whole foods like fruits, vegetables, and nuts, with minimal preparation.
- Processed culinary ingredients: Substances such as oil, salt, and sugar.
- Processed foods: Combinations of group one and two ingredients, like canned beans.
- Ultra-processed foods (UPFs): Industrial formulations with refined ingredients and additives, low in whole foods, designed for convenience and palatability. Examples include sugary drinks and packaged snacks.
Statistics on Canadian processed food consumption
Statistics Canada data highlights the significant presence of UPFs in the Canadian diet: {Link: ncbi.nlm.nih.gov https://pmc.ncbi.nlm.nih.gov/articles/PMC8076355/}
- Almost 46% of adult daily energy intake came from UPFs in 2015.
- Children and adolescents consume even higher amounts, with over 50% of daily energy from UPFs.
- Consumption is higher among certain demographics, including younger adults and those with food insecurity.
- Canada had the fourth highest per capita UPF sales among 80 countries in 2016.
Factors driving UPF consumption in Canada
Several factors contribute to high UPF intake in Canada: {Link: ncbi.nlm.nih.gov https://pmc.ncbi.nlm.nih.gov/articles/PMC8076355/}
- Convenience and availability: Busy lifestyles increase demand for easy-to-prepare foods, and UPFs are widely available.
- Cost: UPFs can appear more affordable upfront, though long-term health costs are significant.
- Marketing: UPFs are heavily marketed, influencing food choices, especially in children. Their palatability also encourages overconsumption.
- Societal shifts: Increased UPF consumption reflects broader changes in how Canadians obtain and prepare food.
The health implications of a UPF-heavy diet
High UPF intake in Canada is linked to various chronic health issues:
- Obesity: Strongly associated with increased obesity risk from a young age.
- Cardiovascular disease: Linked to a significant percentage of heart disease and stroke cases and deaths.
- Diabetes and hypertension: Increases the risk of developing these conditions, which are major risk factors for heart disease.
- Inflammation: A recent study connected UPF consumption to indicators of inflammation.
Minimally Processed vs. Ultra-Processed Food
| Feature | Minimally Processed Foods | Ultra-Processed Foods |
|---|---|---|
| Definition | Whole foods that are washed, chopped, refrigerated, or frozen. | Industrial formulations containing little to no whole foods, with added sugars, salts, and fats. |
| Nutritional Profile | Nutrient-dense, high in fiber, vitamins, and minerals. | Often energy-dense but nutrient-poor, high in sodium, sugars, and saturated fats. |
| Ingredients | Few, often recognizable as whole foods (e.g., frozen vegetables, canned tuna in water). | Many industrial ingredients and additives (e.g., preservatives, flavor enhancers). |
| Convenience | May require more preparation time, although options like pre-cut veggies are convenient. | Highly convenient, ready-to-eat, and ready-to-heat. |
| Cost | Can be more expensive than UPFs, especially out of season, but budget-friendly options exist. | Often perceived as more affordable, especially compared to fresh ingredients. |
| Health Impact | Associated with lower risk of chronic disease and better overall health. | Linked to increased risk of obesity, diabetes, hypertension, and heart disease {Link: ncbi.nlm.nih.gov https://pmc.ncbi.nlm.nih.gov/articles/PMC8076355/}. |
Recommendations and strategies for a healthier diet
Canada's Food Guide advises limiting highly processed foods and prioritizing whole, minimally processed options, fruits, vegetables, and plant-based proteins, with water as the main drink.
Strategies to reduce UPF intake include:
- Cook more often: Prepare meals from scratch to control ingredients.
- Read food labels: Check ingredient lists and nutrition facts for sodium, sugar, and fat. Front-of-pack labeling also helps.
- Choose healthy snacks: Keep whole foods like fruits and nuts available.
- Be critical of marketing: Recognize how advertising influences food choices.
- Make healthy swaps: Choose water over sugary drinks and make homemade versions of favorite packaged items.
Conclusion
Canada's high consumption of ultra-processed foods presents a public health concern, with national data confirming high intake levels linked to chronic diseases such as obesity, diabetes, and heart disease. The convenience and marketing of these products contribute to their prevalence. However, Canada's Food Guide offers guidance towards a healthier diet by recommending limits on highly processed foods and promoting whole, minimally processed options and home cooking. By adopting practical strategies like reading labels and making healthier swaps, Canadians can improve their dietary patterns and overall health.
