A Comprehensive Review of the Triangular Relationship among Diet–Gut Microbiota–Inflammation

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(17), P. 9366 - 9366

Published: Aug. 29, 2024

The human gastrointestinal tract hosts a complex and dynamic community of microorganisms known as the gut microbiota, which play pivotal role in numerous physiological processes, including digestion, metabolism, immune function. Recent research has highlighted significant impact diet on microbiota composition functionality, consequential effects host health. Concurrently, there is growing evidence linking to inflammation, key factor many chronic diseases such inflammatory bowel disease (IBD), obesity, diabetes, cardiovascular (CVDs). This review explores how dietary components influence composition, these microbial changes affect pathways, therapeutic implications modulating this axis for prevention management. Beneficial patterns, Mediterranean (MD) plant-based diets, promote diverse balanced supporting anti-inflammatory pathways. Conversely, Western (WD), high saturated fats refined sugars, associated with dysbiosis increased inflammation. With all links between three variables considered, attempts offer thorough examination triangle formed by food.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder that significantly increases the risk of cardiovascular disease, which leading cause morbidity and mortality among diabetic patients. A central pathophysiological mechanism linking T2DM to complications oxidative stress, defined as an imbalance between reactive oxygen species (ROS) production body’s antioxidant defenses. Hyperglycemia in promotes stress through various pathways, including formation advanced glycation end products, activation protein kinase C, mitochondrial dysfunction, polyol pathway. These processes enhance ROS generation, endothelial vascular inflammation, exacerbation damage. Additionally, disrupts nitric oxide signaling, impairing vasodilation promoting vasoconstriction, contributes complications. This review explores molecular mechanisms by pathogenesis disease T2DM. It also examines potential lifestyle modifications, such dietary changes physical activity, reducing mitigating risks this high-risk population.
