Beneficial effects of soy phytoestrogen intake in postmenopausal women with type 2 diabetes.
OBJECTIVE Phytoestrogen consumption has been shown to reduce risk factors for cardiovascular disease . Type 2 diabetes confers an adverse cardiovascular risk profile particularly in women after menopause . The aim of this study was to determine whether a dietary supplement with soy protein and isoflavones affected insulin resistance , glycemic control , and cardiovascular risk markers in postmenopausal women with type 2 diabetes . RESEARCH DESIGN AND METHODS A total of 32 postmenopausal women with diet-controlled type 2 diabetes completed a r and omized , double blind , cross-over trial of dietary supplementation with phytoestrogens ( soy protein 30 g/day , isoflavones 132 mg/day ) versus placebo ( cellulose 30 g/day ) for 12 weeks , separated by a 2-week washout period . RESULTS Compliance with the dietary supplementation was > 90 % for both treatment phases . When compared with the mean percentage change from baseline seen after 12 weeks of placebo , phytoestrogen supplementation demonstrated significantly lower mean values for fasting insulin ( mean + /- SD 8.09 + /- 21.9 % , P = 0.006 ) , insulin resistance ( 6.47 + /- 27.7 % , P = 0.003 ) , HbA(1c ) ( 0.64 + /- 3.19 % , P = 0.048 ) , total cholesterol ( 4.07 + /- 8.13 % , P = 0.004 ) , LDL cholesterol ( 7.09 + /- 12.7 % , P = 0.001 ) , cholesterol/HDL cholesterol ratio ( 3.89 + /- 11.7 % , P = 0.015 ) , and free thyroxine ( 2.50 + /- 8.47 % , P = 0.004 ) . No significant change occurred in HDL cholesterol , triglycerides , weight , blood pressure , creatinine , dehydroepi and rosterone sulfate , and rostenedione , and the hypothalamic-pituitary-ovarian axis hormones . CONCLUSIONS These results show that dietary supplementation with soy phytoestrogens favorably alters insulin resistance , glycemic control , and serum lipoproteins in postmenopausal women with type 2 diabetes , thereby improving their cardiovascular risk profile
