Introduction: Phytoestrogens are plant-derived compounds with structural similarity to 17-β-estradiol. They are considered safer substitutes for synthetic drugs, especially in the treatment of menopause related symptoms. They are delivered to the body with diet or as dietary supplements.
Aim of the study: The aim of the study was to assess consumer awareness of taking phytoestrogens with diet and supplements, as well as the benefits and risks of such supplementation.
Materials and methods: An original survey form was created for the purpose of the study, 133 questionnaires were completed online, and 100 were distributed to random respondents in the Silesian Voivodship. The vast majority of the respondents (84.5%) was represented by women. The study group was diverse in terms of age, education and place of residence.
Results: Most of the respondents (67.4%) encountered the concept of phytoestrogens. Common plants as: flax, sunflower, pumpkin, European olive and hops were indicated as phytoestrogen main sources. A small group of respondents (6%) was convinced of the effectiveness of phytoestrogens and indicated their specific health-promoting activities, 49.4% said that not every therapy with their use would improve health and 42.9% declared lack of knowledge in this area. According to the survey outcomes, 16.7% of respondents unambiguously confirmed beneficial effect of phytoestrogens on menopause symptoms. Half of the respondents had no opinion whether phytoestrogens could be an effective replacement for synthetic drugs based therapies.
Conclusions: Incomplete knowledge of society regarding the use of phytoestrogens indicates the need for raising awareness of patients/consumers in this area by medical staff and dietitians. Phytoestrogens, when taken responsibly, can have many benefits for human health.
