ARTICLE HIGHLIGHTS
Research background
Type 2 diabetes mellitus (T2DM) is a chronic, non-communicable disease characterized by changes in metabolism that result in high blood glucose levels. Therefore, it is essential to continue research to develop new approaches and strategies that reduce the incidence and prevalence of this disease, promoting an improvement in health and quality of life.
Research motivation
T2DM etiology is closely tied to imbalanced dietary practices. Conversely, a sufficient intake of dietary fiber (DF) has consistently demonstrated health benefits in numerous studies and research endeavors over time.
Research objectives
To investigate the efficacy of DF interventions in the management of T2DM.
Research methods
We searched the Scopus, PubMed, and Web of Science databases up to July 2023, using the terms "dietary fiber" AND "diabetes mellitus".
Research results
Following a thorough analysis and the application of the exclusion criteria, 26 articles were ultimately included in this review. Regarding DF consumption, we identified three methods: Utilizing drugs, such as amylase enzyme inhibitors, in two articles; ingestion of DF supplements, including inulin, fructans, guar gum, resistant starch, resistant dextrin, galacto-oligosaccharides, and psyllium; and increasing the intake of fiber-rich foods in the diet, as discussed in 10 articles.
Research conclusions
The collective findings indicate that glycemic control can be improved by a diet incorporating DF, using the aforementioned methods.
Research perspectives
The results of this systematic literature review expand the current literature, indicating promising results regarding the isolated and combined strategy of calorie restriction and increased DF intake, which can synergistically contribute to notably benefiting T2DM.
