Effects of a dietary portfolio of cholesterol-lowering foods vs lovastatin on serum lipids and C-reactive protein

Jenkins, David J. A.·2003·JAMA

Abstract

CONTEXT: To enhance the effectiveness of diet in lowering cholesterol, recommendations of the Adult Treatment Panel III of the National Cholesterol Education Program emphasize diets low in saturated fat together with plant sterols and viscous fibers, and the American Heart Association supports the use of soy protein and nuts. OBJECTIVE: To determine whether a diet containing all of these recommended food components leads to cholesterol reduction comparable with that of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins). DESIGN: Randomized controlled trial conducted between October and December 2002. SETTING AND PARTICIPANTS: Forty-six healthy, hyperlipidemic adults (25 men and 21 postmenopausal women) with a mean (SE) age of 59 (1) years and body mass index of 27.6 (0.5), recruited from a Canadian hospital-affiliated nutrition research center and the community. INTERVENTIONS: Participants were randomly assigned to undergo 1 of 3 interventions on an outpatient basis for 1 month: a diet very low in saturated fat, based on milled whole-wheat cereals and low-fat dairy foods (n = 16; control); the same diet plus lovastatin, 20 mg/d (n = 14); or a diet high in plant sterols (1.0 g/1000 kcal), soy protein (21.4 g/1000 kcal), viscous fibers (9.8 g/1000 kcal), and almonds (14 g/1000 kcal) (n = 16; dietary portfolio). MAIN OUTCOME MEASURES: Lipid and C-reactive protein levels, obtained from fasting blood samples; blood pressure; and body weight; measured at weeks 0, 2, and 4 and compared among the 3 treatment groups. RESULTS: The control, statin, and dietary portfolio groups had mean (SE) decreases in low-density lipoprotein cholesterol of 8.0% (2.1%) (P =.002), 30.9% (3.6%) (P<.001), and 28.6% (3.2%) (P<.001), respectively. Respective reductions in C-reactive protein were 10.0% (8.6%) (P =.27), 33.3% (8.3%) (P =.002), and 28.2% (10.8%) (P =.02). The significant reductions in the statin and dietary portfolio groups were all significantly different from changes in the control group. There were no significant differences in efficacy between the statin and dietary portfolio treatments. CONCLUSION: In this study, diversifying cholesterol-lowering components in the same dietary portfolio increased the effectiveness of diet as a treatment of hypercholesterolemia.

  • The LDL-C lowering effect of the Portfolio dietary pattern components was additive when combined as part of the dietary pattern.

    “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]”
  • An early randomized controlled trial showed that the maximal LDL-C lowering efficacy of the Portfolio dietary pattern was similar to that of 20 mg lovastatin (-28.6% versus -30.9%) in a head-to-head comparison when all foods were provided under metabolically controlled conditions.

    “An early randomized controlled trial showed the maximal LDL-C lowering efficacy was similar to that of 20 mg lovastatin (-28.6% versus -30.9%) in a “head-to-head” comparison when all foods were provided under metabolicallycontrolled conditions 10”
  • 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]”
  • Nutraceuticals can be useful in statin intolerance if they improve low-grade systemic inflammation and lipid abnormalities, with LDL-C reductions usually below 10-20%.

    “With this background, nutraceuticals can be very useful in case of statin intolerance if they improve the control of low-grade systemic inflammation (157) and lipid abnormalities (LDL-C reduction usually <10% to 20%).”

  • The mechanisms through which hPDI could reduce CHD risk are likely shared with the mechanisms for type 2 diabetes risk reduction.

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.
