Association between the nutritional quality of Canadian packaged foods and their prices: an analysis across five food categories.
Article in Public health nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the association between nutritional quality and food prices within the same food category by: (1) identifying price differences among products above or below the nutrient thresholds of the Canadian front-of-package nutrition symbol and (2) investigating price differences among products with differing numbers of nutrients exceeding these thresholds.
designThis study is part of the Food Quality Observatory's work, Québec (Canada).
settingFor each product, nutrients exceeding the thresholds for Na, sugars and saturated fat were calculated according to Health Canada's guidelines. Prices per 100 g and per 100 kcal (418 kJ) were calculated. Statistical analyses were performed using RStudio to evaluate the association between these price metrics and nutritional quality, based on these thresholds.
participantsFive food categories were analysed: sliced breads (
resultsResults indicate that nutrient type mediates the association between price and nutritional quality. Products exceeding the saturated fat threshold were generally more expensive, whereas those with elevated sugars and Na contents were cheaper. Products with two nutrients exceeding thresholds tended to cost less than those with one or no nutrient above thresholds. Notably, these results varied within each food category. These patterns varied across food categories.
conclusionFoods high in nutrients of concern are typically cheaper within their category, except those high in saturated fat. Findings highlight the importance of monitoring food prices, especially as Canada's nutrition symbol policy becomes mandatory, to prevent worsening health inequalities.
