Effects of Monounsaturated Fatty Acids on Glycaemic Control in Patients with Abnormal Glucose Metabolism: A Systematic Review and Meta-Analysis
Abstract
Background/Aims: In 2008, the American Diabetes Association recommended low-carbohydrate or low-fat diets for weight management in patients with established type 2 diabetes (T2D), while the amount of monounsaturated fatty acids (MUFA) was not specified. This systematic review focused on the effects of diets high in MUFA versus diets low in MUFA on important risk factors of T2D (i.e. plasma glucose, insulin, homeostasis model assessment of insulin resistance and glycosylated haemoglobin, HbA1c). Methods: Nine randomized controlled intervention trials with a total of 1,547 participants and a running time of at least 6 months, comparing diets high versus low in MUFA among adults with abnormal glucose metabolism (T2D, impaired glucose tolerance and insulin resistant), being overweight or obese, have been included in the meta-analysis. We performed a random effects meta-analysis to determine the weighted mean differences with 95% confidence intervals using the software package Review Manager 5.0.25 of the Cochrane Collaboration. Results: Significant differences in HbA1c were found (weighted mean difference –0.21%, 95% CI –0.40 to –0.02; p = 0.03), favouring the high MUFA groups. In contrast, fasting plasma glucose, fasting plasma insulin as well as the homeostasis model assessment of insulin resistance were not affected by the amounts of MUFA in the dietary protocols. Conclusions: In summary, this systematic review found that high MUFA diets appear to be effective in reducing HbA1c, and therefore, should be recommended in the dietary regimes of T2D.

TL;DR
This systematic review and meta-analysis of 9 long-term RCTs in people with abnormal glucose metabolism found that high-MUFA diets (≥12% of total energy) significantly lowered HbA1c compared with low-MUFA diets. Fasting plasma glucose, fasting insulin, and HOMA-IR did not differ significantly between high- and low-MUFA diets.
Key findings
- HbA1c was significantly reduced with high- vs low-MUFA diets: WMD −0.21% (95% CI −0.40 to −0.02; p = 0.03; 5 studies, 667 participants; I² = 15%). The high-MUFA vs low-fat subgroup also showed a significant reduction: WMD −0.28% (95% CI −0.52 to −0.03; p = 0.03).
- Fasting plasma glucose did not differ significantly: WMD −3.02 mg/dl (95% CI −6.66 to 0.63; p = 0.11; 9 studies, 1,545 participants; I² = 81%).
- Fasting plasma insulin did not differ significantly: WMD −0.05 (95% CI −1.60 to 1.49; p = 0.94; 9 studies, 1,547 participants; I² = 84%).
- HOMA-IR did not differ significantly: WMD −0.26 (95% CI −0.75 to 0.24; p = 0.31; 6 studies, 1,355 participants; I² = 86%).
Methods
- Systematic review and meta-analysis of RCTs in participants with abnormal glucose metabolism (IGT, T2D, IR), BMI ≥25, intervention/follow-up ≥6 months, and nutritional counselling by a dietician. Searches covered Medline (1966–May 2011), Embase (1980–May 2011), and the Cochrane Trial Register (until May 2011).
- Included 9 RCTs with 1,547 participants; intervention durations ranged from 6 months to 4 years. High-MUFA diets were defined as ≥12% of total energy content (TEC); low-MUFA diets as ≤12% TEC, including low-fat, low/high glycaemic index, high-protein, and control diets.
- Random-effects meta-analysis using Review Manager 5.0.25; outcomes were fasting plasma glucose, fasting plasma insulin, HOMA-IR, and HbA1c. Results reported as weighted mean differences (WMDs) with 95% CIs; heterogeneity assessed with Q and I²; funnel plots assessed publication bias; Jadad score assessed study quality.
Limitations
- Stated: unpublished data were not considered; included publications varied in diet types, MUFA definitions, study populations, intervention time, and follow-up protocols; drug regimens were not identical across participants; mixed IGT, IR, and T2D populations were included, and effects might be especially strong in T2D. The funnel plot for HbA1c showed little asymmetry/small potential publication bias.
- Evident: heterogeneity was substantial for fasting plasma glucose, fasting plasma insulin, and HOMA-IR (I² >80%), so those pooled null estimates should be interpreted cautiously; the significant HbA1c finding rests on 5 studies and 667 participants.

The authors state this as an assumption.
Imputing the baseline standard deviation for one trial is a valid procedure because baseline and post-intervention standard deviations were similar in the other included trials.
“We assumed that this is a valid procedure, since the baseline and post-intervention SD were found to be similar within the other trials included in the metaanalysis.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
