Phytochemicals as Dual Modulators of Gut Microbiota and Metabolic Disorders: Potential in Obesity-Linked Diabetes
Year: 2025
Type: article
Abstract: Obesity and type 2 diabetes mellitus (T2DM) are complex metabolic disorders with a strong interplay between gut microbiota and host metabolism. Emerging evidence suggests that phytochemicals bioactive compounds derived from plants can modulate gut microbiota composition and function, thereby influencing metabolic health. This review explores the potential of phytochemicals as dual modulators that regulate gut microbiota and mitigate obesity-induced insulin resistance. Key phytochemicals, including polyphenols, flavonoids, alkaloids, and terpenoids, are examined for their ability to enhance gut microbial diversity, promote beneficial bacterial growth, and suppress pro-inflammatory pathways implicated in metabolic dysfunction. Furthermore, the mechanisms through which these compounds improve glucose homeostasis and lipid metabolism are discussed. The therapeutic implications of integrating phytochemicals into dietary and pharmaceutical strategies for managing obesity-linked diabetes are also highlighted. Future research directions should focus on clinical validation and the identification of specific microbial signatures influenced by phytochemicals to tailor precision nutrition approaches.
