Isoflavones prevent bone loss following ovariectomy in young adult rats
Soy protein, a rich source of phytoestrogens, exhibit estrogen-type bioactivity. The purpose of this study was to determine if ingestion of isoflavones before ovariectomy can prevent bone loss following ovariectomy. Twenty-four nulliparous Wistar rats were randomly divided into four groups. In the normal diet groups, a sham operation was performed on Group A, while ovariectomy was performed on ...
متن کاملIsoflavones and functional foods alter the dominant intestinal microbiota in postmenopausal women.
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...
متن کاملDietary isoflavones alter regulatory behaviors, metabolic hormones and neuroendocrine function in Long-Evans male rats
BACKGROUND: Phytoestrogens derived from soy foods (or isoflavones) have received prevalent usage due to their 'health benefits' of decreasing: a) age-related diseases, b) hormone-dependent cancers and c) postmenopausal symptoms. However, little is known about the influence of dietary phytoestrogens on regulatory behaviors, such as food and water intake, metabolic hormones and neuroendocrine par...
متن کاملSoy isoflavones have an antiestrogenic effect and alter mammary promoter hypermethylation in healthy premenopausal women.
We determined if soy isoflavones have dose-related estrogenic and methylation effects. Thirty-four healthy premenopausal women were randomized to 40 mg or 140 mg isoflavones daily through one menstrual cycle. Breast specific and systemic estrogenic effects were assessed measuring the estrogenic marker complement (C)3 and changes in cytology, whereas methylation assessment of 5 cancer related ge...
متن کاملAlteration in the hypothalamic-pituitary-ovarian axis in depressed women.
BACKGROUND Stress and corticotropin-releasing hormone inhibit the reproductive axis. We hypothesized that reproductive axis hormone secretion, particularly luteinizing hormone secretion, is inhibited in women with depression, similar to what has been observed to be caused by stress in numerous species. METHODS Blood samples were collected every 10 minutes for 12 hours in 25 untreated premenop...
