Nutritional Assessment of Pesticide-associated Metabolic Stress in Plant-based Diets.

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
BACKGROUND/
aimChronic low-dose pesticide exposure through high fruit and vegetable consumption is an underappreciated risk factor for metabolic dysfunction. While plant-based diets provide antioxidants and polyphenols, co-exposure to pesticide residues and heavy metals may induce subtle but clinically relevant biochemical disruptions. MATERIALS AND
methodsWe analyzed the detailed metabolomic organic acid profiles from 26 individuals reporting high intake of conventionally grown fruits and vegetables. Dietary modeling was performed to estimate daily polyphenol intake, while metabolomic data were evaluated for markers of detoxification stress, oxidative damage, mitochondrial function, gut dysbiosis, and heavy metal burden.
resultsBoth profiles revealed reproducible patterns of metabolic disturbance, including elevated methylmalonic acid, formiminoglutamic acid, and xanthurenic acid (suggestive of methylation and B-vitamin deficits); increased lipid peroxides and 8-OHdG (indicative of systemic oxidative stress); raised Krebs cycle intermediates and β-hydroxybutyrate (suggesting mitochondrial dysfunction); mild to moderate dysbiosis markers and evidence of fungal overgrowth; and elevated mercury levels exceeding reference thresholds. Despite estimated high polyphenol intake (2.5-3.5 g/day), antioxidant biomarkers remained elevated, supporting the hypothesis of pesticide-induced oxidative burden.
conclusionThese findings suggest that chronic dietary pesticide exposure - even at regulatory-compliant levels - may produce a consistent metabolomic signature, particularly when at least five different pesticide, herbicide, or fungicide residues are simultaneously detected, highlighting the potential for cumulative biological effects characterized by oxidative stress, detoxification pathway strain, gut microbiome disruption, and mitochondrial impairment. This underscores the need for integrated dietary strategies to reduce contaminant intake and highlights the importance of further cohort studies to clarify health impacts and guide nutritional interventions.
