Impact of dietary fiber intake on insulin resistance in type 2 diabetes: A systematic review.
Review in Journal of education and health promotion, 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
This systematic review examines the impact of dietary fiber intake on insulin resistance in individuals with type 2 diabetes mellitus (T2DM). Given the global rise in T2DM prevalence and the central role of insulin resistance in its pathophysiology, there is an increasing emphasis on nonpharmacological interventions, such as dietary fiber, to manage glycemic outcomes. A comprehensive search was conducted across six databases including PubMed, Scopus, Web of Science, ProQuest, CINAHL, and CENTRAL, focusing exclusively on randomized controlled trials (RCTs) up to June 2022. Thirteen RCTs, involving a total of 641 participants, were included in the final synthesis. The interventions varied in fiber type (soluble, insoluble, and mixed), source (whole grains, legumes, flaxseed, composite flour), and dosage (5-50 g/day), with durations ranging from 1 to 6 months. Findings consistently demonstrated that dietary fiber, especially soluble and mixed types, significantly improved insulin resistance as measured by HOMA-IR and related indices. Additionally, notable improvements were observed in fasting glucose, HbA1c, LDL cholesterol, and body weight in several trials. While the results are promising, limitations, such as short study durations, small sample sizes, heterogeneity in intervention protocols, and limited long-term data, constrain broader generalization. Despite these challenges, the evidence strongly supports dietary fiber as an effective adjunct in managing insulin resistance in T2DM. The review underscores the need for longer-duration, multicenter RCTs with standardized fiber interventions to confirm findings and inform clinical practice. Dietary fiber should be integrated into individualized diabetes management strategies to enhance metabolic outcomes and overall health.
