A lipid-sensitive food choice behavior influences aging outcomes from a longevity-promoting diet.
Article in The FEBS journal, 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
Organisms utilize sophisticated neurocircuitry to select optimal food sources. Methylobacterium is a lifespan-promoting diet for C. elegans that drives faster development and longevity; however, after ingestion, C. elegans consistently choose any other food option available. A screen for genetic regulators of this avoidance behavior toward Methylobacterium identified the AWB/AWC sensory neurons and the odr-1 guanylate cyclase expressed in those four ciliated neurons as mediators of the aversive response. Metabolic profiling of the Methylobacterium diet reveals enrichment for saturated fats, and here, we show that C. elegans sense and integrate signals related to these ingested lipids that subsequently cue food-related behaviors. Moreover, disruption of endogenous lipid metabolism modifies the intensity of the avoidance from Methylobacterium, suggesting the current state of lipid homeostasis influences food preference. Taken together, our work reveals that C. elegans modify food choice contemporaneously based in part on the chemosensory capacity to detect and utilize dietary lipids, which has longevity-promoting consequences.
