Using the Nutri-Score to visualise food reformulation in Germany: the case of breakfast cereals.
Article in BMC public health, 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
backgroundThe reformulation of commonly consumed foods towards less sugar, fat, and salt is an important public health strategy to improve food choices of consumers and thus address the high prevalence of overweight and obesity. Front-of-pack nutrition labels like the Nutri-Score may drive reformulation and support nutritionally favourable food choices. Breakfast cereals are of special interest in that they tend to be high in sugar and are relatively often targeted at children. This study therefore aimed to evaluate the German breakfast cereal market in terms of reformulation efforts and to what extent these would show in a better Nutri-Score.
methodsUsing data from the German monitoring of packaged foods, changes in energy and nutrient content and the final nutritional score (FNS) of breakfast cereals, differentiated into children's and non-children's products, between 2019 (n = 888) and 2022 (n = 1473) were evaluated (Mann-Whitney test for two independent samples). Reformulation efforts were analysed in a subsample of paired products available in both years (n = 424). The Nutri-Score was calculated using the 2023 algorithm.
resultsSugar content of children's and non-children's breakfast cereals decreased by 25.5% (p < 0.001) and 8.7% (p < 0.001), respectively, while fat content increased (+ 32.0% (p < 0.001) and + 7.0% (p < 0.036)). Especially for children's breakfast cereals, the share of products with a 'green' (A or B) Nutri-Score was higher in 2022 than in 2019. At the same time, the share of less favourable breakfast cereals (Nutri-Score C-E) was higher for children's than for non-children's breakfast cereals in both years. For paired products, the FNS changed (positively or negatively) in 34.6% and concomitantly the Nutri-Score in 14.2% of cases. Products showing a better Nutri-Score were often reformulated in a way to just make it into the better class.
conclusionImprovements in nutrient content and FNS of breakfast cereals in Germany were mainly driven by shifts in the product portfolio, not by reformulation of existing products. Hence, any benefit for public health would require that consumers switch to (newly introduced) breakfast cereals with a more favourable composition. Overall, more reformulation efforts guided by a holistic product monitoring are needed to improve the nutritional quality of the food supply.
