Effects of inclusion of dietary fibers in the composition of the diet in obesity

Abstract

Background. In recent years, clinical work, discovered a correlation between the violations of quantitative and/or qualitative composition of the intestinal microbiota and the development of various dysmetabolic disorders, including obesity. Aims. To evaluate the effect of the additional inclusion in the diet program of foods with a high content of dietary fibers and microbiotics on anthropometric indicators of obesity. Materials and methods. The dynamic 6-month observation study included 50 people with 23 degrees of obesity (BMI35 kg/m2) according to WHO criteria, divided depending on the method of exposure (the traditional scheme of rational diet/or additionally enriched diet with fiber) into two comparable groups. Among the methods of the study were allocated anthropometry, the actual nutritional analysis and chromatographic study of short-chain fatty acids in the feces. Results. Analysis of anthropometric data (body weight, BMI, waist circumference) using the Wilcoxon test showed a more pronounced dynamics of basic anthropometric data in the group with additional enrichment diet dietary fiber (p0.01). The data of chromatographic studies showed more significant changes in the total concentration of short chain fatty acids (p0.01) and in their profile (p0.05) in the group with additional enrichment diet dietary fiber. Clinically normalization of symbiotic digestion in the intestine in the group with additional enrichment diet dietary fiber was confirmed by reducing the frequency of presented complaints, for flatulence and flatulence from 38.3% to 13.7% (p0.05), abdominal discomfort from 63.4% to 25.5% (p0.05), constipation from 44.5% to 13.8% (p0.05), rumbling in the abdomen on palpation from 50.4% to 18.8% (p0.05). Conclusions. Complex effect of dietary fiber within the food products of functional purpose on the processes and symbiotic digestion in the gastrointestinal tract leads to improved clinical and metabolic (normalization of functional activity of the intestinal microbiota) and anthropometric parameters (lower values of body weight, waist circumference), which predetermines the possibility of using dietary fiber in programmes for the treatment and prevention of obesity.
