Relationship between Oat Consumption, Gut Microbiota Modulation, and Short-Chain Fatty Acid Synthesis: An Integrative Review
The gut microbiota comprises microorganisms that ferment dietary fibers and help play a role in digestion and disease prevention. Diet influences gut microbiota composition, with fiber-rich diets promoting beneficial microbial profiles. Oats provide both soluble and insoluble fiber and contain bioactive components with prebiotic potential. This integrative review synthesizes emerging evidence on how oat consumption influences the gut microbiota and its metabolic outputs, particularly short-chain fatty acids, highlighting the potential of oats as a functional ingredient.
Learning Objectives:
- Describe the role of oat B-glucan and other oat components in gut microbiota modulation and SCFA production
- Explain the physiological functions of key short-chain fatty acids, in relation to gut and metabolic health
- Interpret findings from human, animal, and in vitro studies evaluating the effects of oat consumption on microbiota composition and cardiometabolic markers
- Apply evidence-based guidelines related to oat intake, food processing, and special populations in dietetics practice
- Healthy gut microbiota and positive impact on digestion
- Importance of fiber and gut microbiota modulation
- Integrative review on the benefits of oat consumption
