Abstract [en]

Background: Little evidence exists regarding the effects of soyconsumption on the metabolic syndrome in humans.Objective: We aimed to determine the effects of soy consumptionon components of the metabolic syndrome, plasma lipids, lipoproteins,insulin resistance, and glycemic control in postmenopausalwomen with the metabolic syndrome.Design: This randomized crossover clinical trial was undertaken in42 postmenopausal women with the metabolic syndrome. Participantswere randomly assigned to consume a control diet (DietaryApproaches to Stop Hypertension, DASH), a soy-protein diet, or asoy-nut diet, each for 8 wk. Red meat in the DASH period wasreplaced by soy-protein in the soy-protein period and by soy-nut inthe soy-nut period.Results: The soy-nut regimen decreased the homeostasis model ofassessment-insulin resistance score significantly compared with thesoy-protein (difference in percentage change:7.40.8; P0.01)or control (12.9 0.9; P 0.01) diets. Consumption of soy-nutalso reduced fasting plasma glucose more significantly than did thesoy-protein (5.30.5%; P0.01) or control (5.10.6%; P0.01) diet. The soy-nut regimen decreased LDL cholesterol morethan did the soy-protein period (5.0 0.6%; P 0.01) and thecontrol (9.5 0.6%; P 0.01) diet. Soy-nut consumptionsignificantly reduced serum C-peptide concentrations comparedwith control diet (8.0 2.1; P 0.01), but consumption ofsoy-protein did not.Conclusion: Short-term soy-nut consumption improved glycemiccontrol and lipid profiles in postmenopausal women with the metabolicsyndrome.
