Asian populations including Koreans are assumed to have a higher isoflavone intake due to the higher consumption of soybean. However, it is difficult to estimate isoflavone intake because there is no isoflavone database in Korea. In this study, an isoflavone database was established with systematic review. Literature with analytical values of Korean soybeans and its products were collected and ...

OBJECTIVE Consumption of soy protein has recently been shown to improve the blood lipid levels in nondiabetic subjects. The purpose of this study was to evaluate if a dietary supplement of soy protein, isoflavones, and cotyledon fiber (Abalon) affects cardiovascular risk markers, blood glucose, and insulin levels in type 2 diabetic subjects. RESEARCH DESIGN AND METHODS Twenty type 2 diabetic ...

BACKGROUND Previous studies have indicated that intake of dietary flavonoids or flavonoid subclasses is associated with the ovarian cancer risk, but presented controversial results. Therefore, we conducted a meta-analysis to derive a more precise estimation of these associations. METHODS We performed a search in PubMed, Google Scholar and ISI Web of Science from their inception to April 25, 2...

Dietary phytoestrogens are suggested to reduce the risk of prostate and colorectal cancer, but the results of epidemiologic studies have not yielded consistent support for this proposed effect, possibly due to inadequate databases of phytoestrogen levels in foods. Biomarkers of phytoestrogen intakes may provide a clearer insight into the relationship between phytoestrogen exposure and the risk ...

OBJECTIVE To investigate whether soy-derived isoflavone extract improves performance in cognitive function and quality of life in Chinese postmenopausal women. DESIGN The study was a 6-month double-blind, randomized, placebo-controlled, parallel group trial. Participants were community-dwelling women aged 55 to 76 years; 191 eligible women were randomly assigned to receive a daily oral intake...

Dietary phytoestrogens, such as isoflavones, are used as food additives to prevent menopause-related disorders. In addition to other factors, their bioavailability strongly depends on the activity of intestinal bacteria but the underlying interactions remain poorly understood. A randomized, double-blind, placebo-controlled study was undertaken with 39 postmenopausal women to characterize change...

Consumption of soyprotein has recently been shown to improve the blood lipid levels in non-diabetic subjects. The purpose of this study was to evaluate if a dietary soyprotein isoflavones affects lipid and blood glucose levels in type 2 diabetic subjects. Twenty six type 2 diabetic patients who had refferd to Ahvaz Jundishapour University Diabetes Center, due to uncontrolled diabetes, participa...

There has been substantial interest in phytoestrogens, because of their potential effect in reducing cancer and heart disease risk. Measuring concentrations of phytoestrogens in urine is an alternative method for conducting epidemiological studies. Our objective was to evaluate the urinary excretion of phytoestrogens as biomarkers for dietary phytoestrogen intake in Mexican women. Participants ...
