Abstract

We conducted a meta-analysis to determine the effect of consumption of psyllium-enriched cereal products on blood total cholesterol (TC), LDL cholesterol (LDL-C) and HDL cholesterol (HDL-C) levels and to estimate the magnitude of the effect among 404 adults with mild to moderate hypercholesterolemia (TC of 5.17-7.8 mmol/L) who consumed a low fat diet. Studies of psyllium cereals were identified by a computerized search of MEDLINE and Current Contents and by contacting United States-based food companies involved in psyllium research. Published and unpublished studies were reviewed by one author and considered eligible for inclusion in the meta-analysis if they were conducted in humans, were randomized, controlled experiments, and included a control group that ate cereal providing </=3 g soluble fiber/d. Eight published and four unpublished studies, conducted in four countries, met the criteria. Analysis of a linear model was performed, controlling for sex and age. Female subjects were divided into two groups to provide a rough estimate of the effect of menopausal status (premenopausal = <50 y, postmenopausal = >/=50 y) on blood lipids. The meta-analysis showed that subjects who consumed a psyllium cereal had lower TC and LDL-C concentrations [differences of 0.31 mmol/L (5%) and 0.35 mmol/L (9%), respectively] than subjects who ate a control cereal; HDL-C concentrations were unaffected in subjects eating psyllium cereal. There was no effect of sex, age or menopausal status on blood lipids. Results indicate that consuming a psyllium-enriched cereal as part of a low fat diet improves the blood lipid profile of hypercholesterolemic adults over that which can be achieved with a low fat diet alone.

  • Controlled feeding trials of the Portfolio dietary pattern demonstrated that each of the components had an LDL-C lowering effect of 5-10%.

    “Controlled feeding trials of the portfolio dietary pattern demonstrated that each of the components had a low-density lipoprotein cholesterol (LDL-C) lowering effect of 5-10% [14][15][16][17][18] and that the effect was additive when combined as part of this dietary pattern.[8][9][10][11][12][13]”

    The Discussion (page not provided) reports that psyllium-enriched cereal lowered LDL-C by 9% compared with control cereal in a meta-analysis of 12 studies. This supports the stated range for psyllium, but the paper does not establish that each component of the Portfolio dietary pattern lowered LDL-C by 5–10%. (LLM, conf=0.85)

    Experimental — accuracy not yet measured

  • The LDL-C lowering effect of 5-10% of each of the 4 core food components can be considered additive.

    “These data provide confirmation that the LDL-C lowering effect of 5-10% [14][15][16][17][18] of each of the 4 core food components can be considered additive, [8][9][10][11][12][13]”

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.
