Abstract

BACKGROUND: Current guidelines recommend diet and lifestyle modifications for primary prevention and treatment of hypertension, but do not encourage dietary pulses specifically for lowering blood pressure (BP). To quantify the effect of dietary pulse interventions on BP and provide evidence for their inclusion in dietary guidelines, a systematic review and meta-analysis of controlled feeding trials was conducted. METHODS: MEDLINE, EMBASE, Cochrane Library, and CINAHL were each searched from inception through 5 May 2013. Human trials ≥3 weeks that reported data for systolic, diastolic, and/or mean arterial BPs were included. Two reviewers independently extracted data and assessed methodological quality and risk of bias of included studies. Effect estimates were pooled using random effects models, and reported as mean differences (MD) with 95% confidence intervals (CIs). Heterogeneity was assessed (χ(2) test) and quantified (I(2)). RESULTS: Eight isocaloric trials (n = 554 participants with and without hypertension) were included in the analysis. Dietary pulses, exchanged isocalorically for other foods, significantly lowered systolic (MD = -2.25 mm Hg (95% CI, -4.22 to -0.28), P = 0.03) and mean arterial BP (MD = -0.75 mm Hg (95% CI, -1.44 to -0.06), P = 0.03), and diastolic BP non-significantly (MD = -0.71 mm Hg (95% CI, -1.74 to 0.31), P = 0.17). Heterogeneity was significant for all outcomes. CONCLUSIONS: Dietary pulses significantly lowered BP in people with and without hypertension. Higher-quality large-scale trials are needed to support these findings. CLINICAL TRIAL REGISTRATION: NCT01594567.

  • Systematic reviews and meta-analyses of randomized controlled trials of viscous fibre, total dietary fibre, and sources of plant protein including dietary pulses and soy protein have shown reductions in SBP/DBP.

    “Systematic reviews and meta-analyses of randomized controlled trials of viscous fibre 48,49 as well as total dietary fibre (inclusive of viscous fibre) 50 and sources of plant protein including dietary pulses and soy protein, have shown reductions in SBP/DBP 51,52 .”

    The Results section (‘Dietary pulses for BP’; page not available) reports that this meta-analysis found a significant reduction in SBP with dietary pulses. DBP was lower only as a nonsignificant estimate (P = 0.17), a qualification missing from the citing sentence. The Methods (‘Study selection’; page not available) also state that soy interventions were excluded; the adjacent citation, not this paper, is offered for soy protein. (LLM, conf=0.85)

  • In a meta-analysis of eight RCTs, legumes reduce SBP by 2 mmHg and lower mean arterial pressure.

    “Legumes also reduce SBP (by 2 mmHg) and lowered mean arterial pressure(231) in a meta-analysis of eight RCTs.”
  • In observational studies and RCTs, legume consumption improves CVD risk factors (waist circumference, cholesterol, BP, CRP, glucose) and is protective against T2DM.

    “In observational studies and RCTs consumption of legumes improves CVD risk factors, such as waist circumference, cholesterol, BP, C-reactive protein, glucose; and is protective against T2DM (224–231).”

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.

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.
