简要总结
This is a clinical study with participants over 18 years of age that meet the selection criteria. This will be 42-day study divided into three phases of 14 days each: 14 days without intervention, 14 days with intervention with functional foods and 14 days without intervention again. With the objective of assess the changes in the postprandial glycemic responses through the gut microbiota and urine metabolites.
详细描述
The increase in postprandial blood glucose constitutes a global epidemic and an important risk factor for the development of prediabetes and type 2 diabetes (T2D). In addition, the elevated postprandial glycemic responses (PPGRs) are an independent risk factor for the development of T2D and are associated with the presence of obesity. Therefore the prediction of PPGRs is a tool that could be used to maintain normal blood glucose concentrations.
Studies have shown inter and intrapersonal differences in PPGRs after consuming the same amount of the same food. Factors that can affect interpersonal differences in PPGRs include genetics, lifestyle, and insulin sensitivity. Another factor that may be involved is the gut microbiota.
The objective of this study is to characterize the postprandial blood glucose levels, gut microbiota and urine metabolites in participants over 18 years of age after a functional foods intervention and observed whether this intervention modifies the postprandial glycemic response through the gut microbiota and urine metabolites.
This will be a 42-day study divided into three phases of 14 days each where the patient will attend four visits: at day 1, 14, 28 and 42. 200 adults who meet the inclusion criteria will be recruited. During the three phases a continuous glucose monitor will be taking intersticial glucose concentrations every 15 min., divided into three phases of 14 days each: 14 days without intervention, 14 days with intervention with functional foods and 14 days without intervention again.In the three phases the following will be determined; anthropometric and biochemical parameters, food consumption, physical activity, lifestyle, metabolites in urine as well as determination of the composition of the intestinal microbiota.

结局指标
主要结局
Changes in postprandial glucose responses
时间窗: 6 weeks
Postprandial glucose concentrations (mmol/L). The incremental area under the curve will be calculated and expressed as mmol\*minutes/litre.
Changes in diversity analysis of intestinal microbiota with and without intervention with functional foods
时间窗: 6 weeks
Based on the gene and species composition of each sample, the Chao1 and Shannon indexes, as well as the observed operational taxonomic units, will be calculated in order to identify the differences in gene and species diversity for each group
次要结局
- Changes in metabolite profiles of urine with and without intervention with functional foods(6 weeks)
- Feasibility of the functional food treatment decision algorithm. Proportion of patients with presumed improvement in postprandial glucose response who have completed the algorithm.(2 weeks)
