Brief Summary:

Purpose of Study (The Effect of Non-Viscous Fibre Supplementation on Glycemic Control (NVFS & GC) in Individuals with Diabetes Mellitus.

Regardless of the remarkable advancement in pharmacotherapy, diabetes mellitus remains a major concern with more than 300 millions living with its complications including CVD. Nutrition is a cornerstone in diabetes management, and increasing total dietary fibre have been shown to decrease HbA1c, fasting glucose, fasting insulin, fructosamine, and HOMA-IR. However, the main underlying mechanism is still not fully understood, and the specific type and proportion of fibre supplementation to be recommended for such individuals is still controversial.

Currently, the available findings/ results from small RCTs are inconsistent. The systematic review method depends on combining data from many small studies in order a pooled estimate of the pooled effect. The purpose of this study is to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) assessing the effect of non-viscous fibre supplementation on fasting glucose and insulin in individuals with diabetes mellitus. We hope the findings of this study will play a role in developing the nutritional guidelines for individuals with diabetes mellitus.
