Food-derived bioactive peptides show potential for enhancing intestinal barrier function (IBF). Further research is needed to identify specific peptides and their mechanisms for therapeutic applications.
Area of Science:
- Nutrition Science
- Gastroenterology
- Immunology
Background:
- Food-derived bioactive peptides are recognized for health benefits, acting as functional foods or nutraceuticals.
- The intestinal barrier function (IBF) is crucial for nutrient absorption and preventing pathogen entry.
- Dysfunctional IBF is linked to diseases like inflammatory bowel disease and metabolic syndrome.
Purpose of the Study:
- To review the effects of food-derived bioactive peptides on the components of the intestinal barrier function.
- To synthesize current knowledge on in vitro and in vivo studies of these peptides in both healthy and disease states.
Main Methods:
- Literature review of studies investigating food-derived bioactive peptides and their impact on intestinal barrier function.
- Analysis of in vitro and in vivo experimental data from healthy and diseased subjects.
Main Results:
- Food-derived bioactive peptides demonstrate a potential to influence the intestinal barrier function.
- Evidence suggests these peptides may modulate key components of the intestinal barrier, including the epithelium and immune cells.
Conclusions:
- Food-derived bioactive peptides hold promise for modifying IBF and potentially aiding in disease management.
- Further investigation is required to isolate specific bioactive peptides and elucidate their precise mechanisms of action for therapeutic development.
