Assessing the nutritional quality of gluten-free packaged foods for children
Bibliographic record
Abstract
Purpose To examine the nutritional quality and nature of gluten-free (GF) products targeted to children. Design/methodology/approach All child-targeted foods were collected from two national grocery retailers in Calgary, Alberta, Canada. Child-targeted products with a GF claim were compared with those without such a claim using two nutrient profiling models, the Pan American Health Organization Nutrient Profiling Model (PAHO) and the 2023 World Health Organization (WHO) Nutrient Profile Model. A secondary analysis then compared the nutrient profile of child-targeted GF products to their product “equivalents”. Findings Approximately 15% ( n = 65) of the 448 products assessed had a GF claim. All products – those with and without a GF claim – had similar levels of protein, fat, saturated fat and trans fat, while 80% of GF claim products had high sugar levels. Ninety-eight percent of GF products exceed nutrients of concern for fat, sugars and/or sodium according to PAHO criteria. When examined using WHO criteria, only 1.5% of GF products would be permitted to be marketed to children—an ironic finding given that all products were included in the study because they were designed to appeal to children. No products in the paired analysis would be permitted to be marketed to children (per WHO). Originality/value Child-targeted GF foods do not warrant the health halo accorded to such products by many consumers. Almost all GFC products exceed thresholds of concern for either sugar, sodium and/or fat. Parents who believe these products are “healthier” options for their children are mistaken.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
