Boosting Microbiota Butyrate Producers to Improve Gut Health
Recruiting now
Conditions studied: Adults 20 to 80 Years
In brief
The human gut microbiota is a dynamic ecosystem essential to health, influenced by diet, age, and lifestyle. It plays a key role in digestion, immunity, and nervous system regulation. Among its important compounds, short-chain fatty acids, particularly butyrate, are crucial for intestinal and metabolic balance, as they support homeostasis, strengthen the epithelial barrier, and have anti-inflammatory effects. An imbalance in the microbiota, especially a decrease in butyrate-producing bacteria, is linked to intestinal, metabolic, and neurological disorders. A fiber-rich diet promotes the growth of these beneficial bacteria. This study aims to isolate and characterize probiotics that can enhance butyrate production, thereby improving intestinal health and microbiota balance. Sampling conditions will comply with regulations governing research involving human subjects.
