Foundation Foods reveals significant changes in farmed Atlantic salmon relative to Standard Reference Legacy data.
Article in Frontiers in nutrition, 2026. 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
Food composition databases are critical for dietary surveillance and commonly used in epidemiological research but must be actively managed to reflect a dynamic food supply. This study presents a practical framework for flagging foods and nutrients where current individual-sample data may warrant review of legacy database values. Herein we compare new individual-sample data to legacy data obtained on composited samples. The fatty acid (FA) profile of farmed Atlantic salmon demonstrates fatty acid species differences not apparent at the class level. While total polyunsaturated FA (PUFA) appeared unchanged between the two datasets, the new profile was 2.4-fold higher in linoleic acid (from 0.900 to 2.152 g/100 g) and 3.4-fold higher in α-linolenic acid than legacy data (0.148 to 0.510 g/100 g), with decreases in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) concentrations. These nutritionally consequential shifts were flagged using a proposed practical concordance framework that compares current individual-sample Foundation Foods estimates with legacy SR values and prioritizes nutrients for further database review. This case study underscores the necessity of continuous investment in food analysis using modern, individual-sample methods. Implementing this framework may help the Foundation Foods sampling program prioritize foods and nutrients where current individual-sample data suggest meaningful divergence from legacy database values.
