Polyphenol diet and exercise as neuroprotective factors in a Drosophila model of Alzheimer's disease.
Article in Animal models and experimental medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundHealthy non-pharmacological lifestyle factors, such as regular physical exercise and dietary supplementation, have been shown to significantly improve cognitive outcomes over time compared to a more sedentary lifestyle and poor diet. Furthermore, exercise may serve as a potential protective factor in attenuating the effects associated with cognitive decline that are characteristic of neurodegenerative disorders, such as Alzheimer's disease (AD). Evidence indicates that certain dietary interventions can also attenuate the effects of neurodegeneration and positively impact longevity. Supplementation with polyphenols such as ellagic acid (EA), which is abundant in pomegranate juice, may help provide neuroprotective and longevity benefits.
methodsThis study examined the potential protective potential of EA and exercise and provides insight into the combined use of a polyphenol-rich diet and exercise to enhance behavioral outcomes and lifespan in a transgenic Drosophila melanogaster (fruit fly) model of AD with the Aβ
resultsFruit flies subjected to a 120-minute exercise regimen performed better on a climbing assay than flies that did not exercise. Conversely, flies that exercised for 30 min passed marginally more trials on a learning and memory assay using an aversive stimulus than flies that did not exercise, whereas both groups performed better than flies subjected to the more intense exercise condition.
conclusionThese results suggest a hormetic effect of exercise regarding memory performance. Finally, flies fed a low dose of dietary EA (0.24 mg/mL) lived significantly longer than flies fed the control diet or higher concentrations of EA, again suggesting a hormetic effect of EA on longevity.
