Introduction: Several studies indicate that estrogen use increase performance on some tests of cognition especially in postmenopausal women. These steroids have many side effects, thus, other estrogenic agents with fewer side effects are needed to develop alternative treatment strategies. The main objection of this study was to evaluate the effects of different doses of dietary soy meals (with ...

OBJECTIVE To assess the effects of soy isoflavone protein concentrate and soy lecithin on endothelial function, measured as flow-mediated dilation (FMD) of the brachial artery in healthy postmenopausal women. DESIGN This was a randomized, double-blind, placebo-controlled crossover trial with 25 participants (mean age, 61 years; body mass index, 25.46 kg/m2). The women underwent endothelial fu...

the increasing prevalence rate of breast cancer among asian-american women shows the more significant role of lifestyle factors in etiology than genetic factors. the search engine pubmed was used for searching related paper by “breast cancer”, “soy”, “isoflavones”, “phytoestrogen” as the key words. we selected papers which published during 1990 to 2012. various experimental studies reported the...

Isoflavones are present in soybeans and its products in concentrations up to 300 mg/100 g, have estrogenic and antiestrogenic properties, and may be protective against hormone-related cancers. The purpose of this cross-sectional study was to investigate the association between urinary isoflavone excretion and self-reported soy intake. A total of 102 women of Caucasian, Native Hawaiian, Chinese,...

OBJECTIVE In a sample of older Japanese American women, we aimed to: (1) describe the most commonly consumed soy foods, (2) estimate dietary soy isoflavone intake, (3) describe characteristics associated with dietary soy isoflavone intake, and (4) compare our estimates with previously published estimates in other Japanese samples. DESIGN A 14-item soy food-frequency questionnaire was administ...

BACKGROUND Conclusions drawn from meta-analyses on the association between soy isoflavone intake and breast cancer risk for pre- and post-menopausal women are not fully consistent. These meta-analyses did not explore the influence of different study designs on the pooled results on the basis of distinguishing between pre- and post-menopausal women. METHODOLOGY AND PRINCIPAL FINDINGS We perfor...

OBJECTIVE Probiotics and prebiotics that affect gut microflora balance and its associated enzyme activity may contribute to interindividual variation in isoflavone absorption after soy intake, possibly enhancing isoflavone bioavailability. This study examined the effects of the consumption of bioactive yogurt (a probiotic) or resistant starch (a known prebiotic) in combination with high soy int...

background: emergence of drug resistance has brought major problems in chemotherapy. using nutrients in combination with chemotherapy could be beneficial for improvement of sensitivity of tumors to drug resistance. soybean-derived isoflavones have been suggested as chemopreventive agents for certain types of cancer, particularly breast cancer. in this study, the synergistic effects of soy isofl...

Isoflavones are thought to have an important role in the prevention of hormonerelated diseases. This study was undertaken to identify the profile of urinary isoflavone metabolites collected within 24 h after the consumption of unfermented or fermented soy foods. The proportions of b-glycosides and aglycones to total isoflavone intake were much higher in soybean paste than soy flour. Twenty urin...
