1 · What the graph read from it

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.

2 · The registry

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

backgroundFAO/WHO have encouraged national governments to create food-based dietary guidelines (FBDGs) to support healthy diets. However, little is known about the extent to which food supply composition aligns with FBDGs, thereby structurally supporting or undermining population-level adherence. It is also unclear how this alignment has evolved over time. The aim of this study was to determine to what extent the global food supply aligns with FBDGs, and to examine historical trends.

methodsDescriptive time series analysis of food supply alignment (FSA), 1961-2013. FSA was characterised as a ratio dividing country-level food supply data by FBDG across four food groups: fruit and vegetables (FV); sugar (SU); fish and seafood (FS); and red and processed meat (RP). FBDG data was collected from guidance produced by international bodies, and from countries with published FBDGs. The food supply was estimated using yearly FAOSTAT data. A population-weighted average of this ratio was created for all countries included in the analysis, and stratified by region and country income.

findingsFBDGs from 89 countries were included. Of those, 80% had country guidelines for FV, 34% for SU, 44% for FS, and 21% for RP. FSA (1.0 = perfect alignment) based on global guidelines showed a higher supply than recommended for FV (1.2), SU (1.2) and RP (1.1). FSA based on country guidelines showed a lower supply than recommended for FV (0.9) and a higher supply than recommended for SU (2.3), RP (2.3) and FS (1.4). FSA also showed substantial differences in levels and trends across region and country income.

interpretationAs of 2013, food supplies were not aligned with national and international FBDGs and misalignment persisted across five decades with subtantial variation in trends based on geography and country income. The long running nature of these trends suggest that the transition toward sustainable and healthful food systems represent a signifiant global challange. Additionally, acknowledging the degree of misalignment between macro-level structural factors, such as the composition of the food supply, in relation to national or global food policy aims may further aid efforts for population level adherence.
