Abstract

This study was aimed to investigate whether or not black soybean supplements affect levels of lipid profiles and female hormone (estradiol; E2, estrogen; Es) in 57 middle-aged women (in their 40s and 50s). All subjects were randomly assigned to the control or black soybean supplement group (BSS group). The BSS group was allocated to use dietary black soybean supplements (100 g/day) for 8 weeks. The BSS subjects were divided into two subgroups; 14 women were in the premenopausal group and 15 were in the postmenopausal group. We measured lipid profiles, female hormones and nutrient intakes at 0 weesk and 8 weeks. After 8 weeks, high-density lipoprotein (HDL) cholesterol was significantly decreased (P<0.01) and the athrogenic index (AI) was significantly increased (P<0.01) in control group. In BSS group, triglyceride (TG) (P<0.05), low-density lipoprotein (LDL) cholesterol (P<0.01) and LDL-HDL ratio (LHR) (P<0.01) were significantly decreased. However, E2 and Es were significantly increased (P<0.01). Compared to the control group, the BSS group revealed statistically significant improvements in the levels of TG, HDL-cholesterol, AI, LHR, E2 and Es (P<0.05). In the premenopausal group, HDL-cholesterol (P<0.05), E2 (P<0.01) and Es (P<0.05) were significantly increased and AI (P<0.01) and LHR (P<0.01) were significantly decreased after 8 weeks. In the postmenopausal group, E2 (P<0.05), and Es (P<0.05) were significantly decreased. However, total cholesterol (TC) was increased (P<0.01). Compared to the postmenopausal group, the premenopausal group was significantly improved on HDL-cholesterol, LDL-cholesterol and LHR (P<0.05). In conclusion, black soybean supplements may have beneficial effects on improving lipid profiles and female hormones.
