Identifying the patterns of ultra-processed food consumption and their characteristics in the UK adults using the UK National Diet and Nutritional Surveys 2008/09 to 2018/19.
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 identify the dietary patterns of ultra-processed food (UPF) consumption in UK adults and to explore their nutritional characteristics and associated demographic and socio-economic factors.
designUPF-based dietary patterns were identified using weighted principal component analysis and k-means cluster analysis on UPF intakes (identified using Nova classification) from the cross-sectional National Diet and Nutrition Survey data (2008-2019). Weighted multivariable logistic regression models were employed to identify the demographic and socio-economic factors associated with the patterns.
settingUnited Kingdom.
participants8347 adults (≥ 18 years).
resultsUPF accounted for 54 % of total energy intake in the UK adult diet. Three distinct UPF-clusters were identified, labelled as 'Sweet Foods', 'Fast Foods' and 'Traditional Foods' based on their predominant food intakes. Older participants (> 68 years) were more likely to adhere to the 'Sweet Foods' pattern (OR: 2·39; 95 % CI: 1·99, 2·87) and less likely to be part of the 'Fast Foods' pattern (OR: 0·47; 95 % CI: 0·40, 0·55) compared with younger individuals (< 29). Participants in lower occupations were less likely to adhere to the 'Fast Foods' pattern than participants in the higher occupations (OR: 0·82; 95 % CI: 0·72, 0·94) while being more likely to adhere to the 'Traditional Foods' pattern (OR: 1·23; 95 % CI: 1·06, 1·43).
conclusionsThe UK diet was dominated by UPF products. Our analysis identified three distinct UPF dietary patterns with varying nutritional quality, influenced by key demographic and social factors. These findings provide valuable insights into the determinants of UPF consumption and highlight which population groups are more likely to consume certain types of UPF.
