The Influence of the "Washoku" Diet on the Gut Microbiota in Postmenopausal Women

Brief summary (registry, in English)

Menopause is a special period in a woman's life, when a sudden drop in estrogen levels leads to the cessation of menstrual cycles. Hormonal changes and a decreasing metabolic rate contribute to weight gain and the appearance of numerous metabolic disorders, such as dyslipidemia, impaired glucose tolerance, insulin resistance, hyperinsulinemia, and type 2 diabetes. Currently, effective and inexpensive dietary therapeutic solutions are being sought to improve the health of this group of women. It is suggested that the Japanese washoku diet, which includes products rich in isoflavones, fiber (soy products) and unsaturated omega-3 fatty acids (fish, seaweed), may be a good solution, as it contributes to the regulation of hormonal balance, lowering cholesterol levels, and reducing the risk of insulin resistance. Moreover, the composition of such a diet may also affect the diversity of the intestinal microbiota and the production of its metabolites, such as short-chain fatty acids, and thus contribute to the improvement of patients' health. Taking the above into account, the aim of the study will be to assess the effect of the Japanese washoku diet on the composition of the intestinal microbiota and its metabolites in a group of overweight or obese women after natural menopause. Specific objectives: * Assessment of anthropometric parameters (body weight, height, waist circumference, hip circumference) and body composition and bone density. * Assessment of parameters of carbohydrate metabolism (glucose, insulin concentration), lipid metabolism (total cholesterol (T-C), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), non-HDL cholesterol (non-HDL-C) and triglycerides). * Analysis of intestinal microbiota, short-chain fatty acids in the feces of women.
