Dietary Modulation of Inflammatory and Oxidative Pathways in Type 2 Diabetes: Biomarkers and Cardiorenal Outcomes.
Review in Nutrients, 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
Type 2 diabetes mellitus is a relevant cardio-renal-metabolic disorder in which chronic low-grade inflammation and oxidative stress have a crucial function in linking insulin resistance, endothelial dysfunction, β-cell impairment, and progressive organ injury. In this context, nutrition has emerged as a key modifiable determinant of metabolic homeostasis, capable of influencing inflammatory signalling, redox balance, mitochondrial function, and gut microbiota-host interactions. The objective of this review is to critically summarise the mechanistic connections among inflammation, oxidative stress, and diabetes progression, and to investigate how dietary factors and patterns, as well as nutrition-responsive biomarkers, influence these pathways and their cardiorenal consequences. We discuss the effects of macronutrient quality, dietary fibre, fatty acids, polyphenols, and specific micronutrients, including vitamin C, vitamin E, selenium, zinc, and magnesium, as well as the role of Mediterranean, DASH, and plant-based diets in improving glycaemic control, endothelial function, and cardio-renal risk profiles. We also summarise established and emerging biomarkers of inflammation and oxidative stress that may improve risk stratification and the evaluation of nutrition-based interventions. Overall, current evidence supports a shift from a purely glucose-centred approach toward an integrated model in which dietary modulation of inflammatory and oxidative pathways helps reduce cardiovascular and renal risk. However, heterogeneity of interventions, variability in biomarker assessment, and interindividual differences in dietary response represent major limitations. Future research should focus on biomarker-informed, precision-oriented nutritional approaches integrated within contemporary cardio-renal-metabolic care.
