Hormone replacement therapy effectively reduces the symptoms associated with decreased estrogen levels, however, frequently the benefits of this therapy do not outweigh the risks. Therefore, natural alternatives are sought to alleviate these symptoms such as phytoestrogens (Chen, M.-N. et al., (2015); Kurzer, M. S., (2018)). Epidemiological studies in Asian populations, where the consumption of soy and other phytoestrogen-rich foods is high, have reported lower incidence of breast cancer, osteoporosis, heart disease and strokes than in the Western populations. Comparing to hormone treatments, these diets have the advantage of not having side effects, mainly thromboembolism or breast cancer (Abdi, F. et al., (2016); Keiler, A. et al., (2013)). Phytoestrogens are non-steroidal plant-derived estrogens, structurally or functionally similar to endogenous estradiol and therefore with estrogen-like properties. They are polyphenolic compounds, which have a chemical structure with an aromatic ring attached to one or more hydroxyl groups, similar to estrogens. Polyphenols are the most abundant antioxidants in the diet, since they are widely distributed in nature and present in plant-based foods, while in the animal kingdom or in humans their presence is due to the ingestion of plant foods and they are only found in relatively low concentrations. Phytoestrogens include a wide variety of structurally different compounds, such as isoflavones, mainly found in soybeans; lignans, found in grains and extra virgin olive oil; stilbenes, found in grape skins and red wine; and xanthohumoles, present in beer hops (Clifton-Bligh, PB et al., (2015)) (Delmanto, A. et al., (2013)) (Keiler, A. et al., (2013)).. Therefore, new studies are needed to evaluate the effects of food with phytoestrogens on different clinical variables related to menopause, such as menopausal symptoms or even osteoporosis. In this context, we are conducting a clinical trial to assess the effects of moderate and regular beer consumption with and without alcohol on these variables, that contain phytoestrogens and other compounds such as silicon that have an effect on bone health. Preliminary results will be discussed.
