Descripción detallada
This randomized, double-blind, placebo-controlled, parallel-group clinical trial will evaluate the effects of agave inulin supplementation on metabolic profile and intestinal abundance of Bifidobacterium and Lactobacillaceae in adults with type 2 diabetes mellitus (T2DM).
Participants will be randomly assigned to receive either agave inulin (10 g/day) or placebo for eight weeks. The intervention will be administered as two daily doses of 5 g consumed before breakfast and before dinner.
Metabolic assessments will be performed at baseline and week 8 and will include fasting glucose, fasting insulin, glycated hemoglobin (HbA1c), insulin resistance (HOMA-IR), total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides. Anthropometric and body composition measurements, including body weight, body mass index (BMI), waist circumference, body fat percentage, and muscle mass percentage, will also be evaluated.
Fecal samples will be collected at baseline and week 8, preserved in DNA/RNA Shield solution, and stored at -80°C until analysis. Microbial DNA will be extracted using the ZymoBIOMICS™ DNA Miniprep Kit. Gut microbiota characterization will be performed through 16S rRNA gene sequencing of the V4 hypervariable region using primers 515F and 806R on the Illumina MiSeq platform. Bioinformatic analyses will be conducted using the QIIME pipeline to determine the abundance of Bifidobacterium and Lactobacillaceae. Statistical analyses will be performed according to the intention-to-treat principle.
