CSI Collaborative Research

The Canadian Sugar Institute is committed to maintaining responsible and transparent processes in all its activities, including engagements and partnerships with interested health professionals and scientific bodies on relevant research, education, and communications projects. We aim to adhere to the guiding principles laid out in the publication “Achieving a transparent, actionable framework for public-private partnerships for food and nutrition research” (Alexander et al., 2015). 

CSI works collaboratively with external experts and researchers while maintaining transparency and scientific rigor. We participate in collaborative research projects that contribute to the understanding of sugars consumption trends in Canada, sugars-related claims and reformulation in the Canadian marketplace, and knowledge and perceptions regarding sugars. All CSI-funded research projects will be published in peer-reviewed journals with open access. CSI conducts collaborative research on the following topics: 

Sugars Consumption in Canada 

The Association Between Added Sugars Intake and the Healthy Eating Food Index 2019 Among Canadians: Analyses from the 2015 Canadian Community Health Survey—Nutrition Public Use Microdata File
F. Wang, Z. Fan, S. Marsden, C. DiAngelo, L. Chiavaroli, M. Ahmed, M. Chung. Nutrients. 2026;18(5):2570

Key findings: 

  • The association between added sugars intake and HEFI scores was negative but non-linear. 
  • There were large variations in HEFI scores among individuals with similar added sugars intakes, suggesting that added sugars alone may not fully capture overall diet quality or adherence to Canada’s Food Guide.  
  • Among high added sugars consumers (>15% EI), lower HEFI scores were largely due to higher proportions of sweetened beverages (i.e., low beverage scores) and lower intakes of vegetables and fruit and plant-based proteins. 
  • Scores for protein food and whole grains were low across all added sugars intake categories.

The association between added sugars intake and key nutrApplied Physiology, Nutrition and Metabolism journal logo ient inadequacy among Canadian adults: Analyses from the Canadian Community Health Survey – Nutrition 2015 Public Use Microdata File
F. Wang, L. Ricciuto, V. Fulgoni III, L. DiFrancesco, D. Kitts, L. Chiavaroli, M. Ahmed, J. Sievenpiper.

Key Findings: 

  • Added sugars intakes (% kcal/d) ranged from <1.3% (decile 1, <4.6g/d) to >18.3% (decile 10, >93.3 g/d) with a median intake of 6.8% kcal/d (28.5 g/d). 
  • Significant inverse associations between added sugars intake deciles and % <EAR were found for calcium, magnesium, and zinc in all adults (p<0.01). In adults aged 71+ years, such inverse associations were also observed for iron, folate, riboflavin, thiamin, and vitamin B6. 
  • Adjusting for energy intakes attenuated the association for calcium but strengthened the association for zinc and rendered the association for magnesium non-significant. 
  • The relationships for calcium, magnesium and zinc in all adults remained significant after removing the lowest and highest deciles of added sugars intakes (deciles 1 and 10).

Association Between Added Sugars Intake and the Healthy Eating Index-2015 among Canadian Children—Analyses from the Canadian Community Health Survey – Nutrition 2015 Public Use Microdata File
F. Wang, L. Chiavaroli, A.P. Ng, L. Ricciuto, C. DiAngelo, S. Marsden, J. Sievenpiper. Canadian Journal of Dietetic Practice and Research. 2022;83(4):216.

Key findings: 

  • There was an inverse association between added sugars intakes and total HEI-2015 scores – the association was non-linear with the greatest reductions in HEI-2015 scores for children at the highest added sugars intakes.
  • For children aged 2-8 years, total HEI scores ranged from 60.7 for those with the lowest added sugars intake (quintile 1 or Q1, <4.1% energy from added sugars), to 48.6 for children with the highest added sugars intake (Q5, >14.0% energy from added sugars). 
  • There was no significant difference in total HEI-2015 scores between children in Q2 to Q4 (with mean added sugars intakes between 4.1 - 14.0% energy).  
  • Based on the component scores, different dietary patterns were observed for intakes of sodium, saturated fat, dairy foods, and whole grains, suggesting distinctive food choices across different levels of added sugars intake.

F. Wang, L. Chiavaroli, A.P. Ng, L. Ricciuto, C. DiAngelo, S. Marsden, J. Sievenpiper.

Key findings: 

  • There was an inverse association between added sugars intakes and total HEI-2015 scores – the association was non-linear with the greatest reductions in HEI-2015 scores for adults at higher intakes of added sugars.
  • For adults (19 years and older), total HEI scores ranged from 57.5 for those with the lowest added sugars intake (quintile 1 or Q1, <2.8% energy from added sugars), to 43.9 for adults with the highest added sugars intake (Q5, >14.0% energy from added sugars). 
  • Reductions in total HEI and component scores for vegetables, fruit, and protein intakes were more prominent for those with the highest intakes of added sugars. 
  • Based on the component scores, different dietary patterns were observed for intakes of sodium, saturated fat, fatty acid rations, dairy foods, and whole grains, suggesting distinctive food choices across different levels of added sugars intake.

Canadian Adults with Moderate Intakes of Total Sugars have Greater Intakes of Fibre and Key Micronutrients: Results from the Canadian Community Health Survey 2015 Public Use Microdata File
Wang Y(F), Chiavaroli L, Roke K, DiAngelo C, Marsden S, Sievenpiper J. Nutrients. 2020;12(4):1124.

Key findings: 

  • Canadian adults consumed on average 18.8 % energy from total sugars, 9.9 % energy from free sugars, and 8.6 % energy from added sugars.
  • Canadian adults with a moderate intake of total sugars had greater intakes of dietary fibre and key micronutrients such as calcium, vitamin D and potassium compared to those with high and low  intakes of total sugars, primarily due to different intakes of fruits, milk, and yogurt.
  • There was an inverse relationship between total sugars and total fat intakes as a % energy across quintiles, which mirrors the “sugar-fat seesaw” phenomenon. This reciprocal relationship was also observed for saturated fat as a % energy.

Journal of the American Nutrition Association logo Trends in Loss-Adjusted Availability of Added Sugars and Energy Contribution from Macronutrients and Major Food Groups in Canada and the United States
Wang Y(F), Marsden S, Chiavaroli L, DiAngelo C, Sievenpiper JL. Journal of the American Nutrition Association. 2022 June; DOI: 10.1080/07315724.2022.2073923.

Key findings: 

  • There was a 17% decline in loss-adjusted per capita consumption of added sugars in Canada over the twenty-year period from 1999 to 2019. This was largely attributed to reduced intakes of refined sugar and sugars in soft drinks. 
  • Added sugars intake in Canada was generally 30% less than that in the US. 
  • There was a consistent decline in total energy intake and % energy from carbohydrates, accompanied by increased % energy from fats, particularly in the last 10 years.
  • Absolute intakes (kcal/day) of food categories such as “fats and oils”, “meat, eggs, and nuts”, “flour and cereal products” also declined and remain below 1999 levels, but have shown an increasing trend in more recent years, suggesting a shift in consumer food choices.

Sugars Claims and Reformulation 

Disconnection between sugars reduction and calorie reduction in baked goods and breakfast cereals with sugars-related nutrient content claims in the Canadian marketplace
Wang YF, Marsden S, Diangelo C, Clarke A, Chung A, Yu J, Fan Z, Cooper J, Kitts D. Front Nutr. 2025;12:1539695.

Key findings: 

  • Despite reductions in sugars, there was no significant difference in Calorie content between claims products compared to non-reformulated reference products. 
    • 49% of “no added sugars” products, 27% of "sugar-free" products, and 23% of "lower/reduced in sugar" products had higher Calories than their reference products. 
    • “Unsweetened" baked goods had significantly more Calories due to higher fat content. 
    • Sugar alcohols, dietary fibres, non-nutritive sweeteners and starch were the most common substitutes for added sugars in claim products.

Knowledge and Perceptions Regarding Sugars

Understanding carbohydrates and sugars: Assessing knowledge and perceptions among university students in CanadaApplied Physiology, Nutrition and Metabolism journal logo
F. Wang, N. Bellissimo, D. Kitts, Z. Fan, D. Ma, B. Luhovyy, S. Cheema, D. Vine, S. Proctor, K. Power, T. Cohen, C. Couillard, S. Pomerleau, C. O'Connor, L. Chiavaroli, M. Suh. 
Key Findings: 
  • Beyond course materials, the top three sources where participants obtained nutrition information were academic journals, government materials, and health association materials. 
  • A gap in glycemia-related knowledge was shown, with only 33.5% correctly selecting “white bread” as having the highest glycemic index from a provided list of foods, and a higher percentage (44%) incorrectly chose “table sugar”. 
  • Only 25.9% of respondents were able to identify correct statements related to glycemic index and glycemic response. 
  • A higher proportion of students majoring in Nutrition or Dietetics correctly answered many basic carbohydrate knowledge questions compared to students in other majors, except questions about glycemic index and dental caries. 
  • In contrast, there were no differences in the accuracy rates between majors on basic sugar knowledge questions. Perceptions of sugars were generally negative, with a higher proportion of students having opinions aligned with common media messages around sugars in the diet.

Wang Y(F), Bellissimo N, Kitts DD, Turgeon O'Brien H, Ma WLD, Suh M, Luhovyy B, DiAngelo C, Pasut L, Marsden S, Chung M, Gurcan A. Journal of the American College of Nutrition. 2020;40(2):164-171. 

Key findings: 

  • Internet-based sources accounted for one-third of the sources where students obtained nutrition information; academic sources ranked second at approximately 27%.
  • Students who indicated more credible sources where they obtained nutrition information had a higher number of carbohydrate-related knowledge questions answered correctly; no difference was observed for sugars-related knowledge questions.
  • A higher percentage of nutrition-majors correctly answered knowledge questions related to carbohydrates compared to nutrition-elective students; no difference was observed between the two groups for sugars-related knowledge questions.
  • Perceptions and attitudes towards sugars were generally negative and did not differ between nutrition-major and nutrition-elective students.
