Abstract

The gut bacteria and the host have a mutually beneficial relationship. This complex interdependence plays a critical role in resource collection via prebiotic carbohydrate breakdown in the intestinal tract, the supply of important nutrients, vitamin synthesis, metabolic operations and maintenance, as well as sheltering against colonization of pathogens, and opportunistic fungal infections. This leads to ‘gut microbiota homeostasis’ or ‘gut microbial equilibrium’, i.e., a stable and healthy gastrointestinal tract microbial community. In this review, we discuss the gut micro biome’s role in the development of the immune system, including oral tolerance and immunity. The therapeutic approach must begin with the interaction of functional foods and enterocytes. Furthermore, we discuss current knowledge and the promising application of functional foods that may stimulate the immune system to perform a further pro- or anti-inflammatory activity in the gastrointestinal system. When evaluating the immune system function of nutraceuticals, designs that modulate the membrane must be used whenever possible. Moreover, nutraceutical products’ claim to be immunity boosters should have valid and accurate data to back it up. While assessing the stimulation of blood cell immunity through functional foods is more useful, it does not accurately reflect physical reality, and an investigation into the colonic immune response is a better way to understand it.

Discussion

The interdependence between the gut microbiota and the host is fundamental for maintaining health. Disruptions in this balance (dysbiosis) can lead to a range of diseases. Functional foods, especially those derived from protein hydrolysates, offer promising avenues for modulating immune responses and improving intestinal health. The review highlights the need for robust data to support claims of immunity-boosting properties of nutraceuticals and emphasizes the importance of studying colonic immune responses for a more accurate assessment of immune system function.

Key Findings

- The gut microbiota and host have a mutually beneficial relationship crucial for nutrient acquisition, vitamin synthesis, metabolic operations, and pathogen defense, leading to gut microbiota homeostasis.
- The gut microbiota plays a critical role in the development of the immune system, including oral tolerance and immunity.
- Dysbiosis, or an imbalance in gut microbial composition, is linked to various diseases and abnormal immune responses.
- Functional foods, particularly protein hydrolysates and bioactive peptides, can modulate the immune system, fortify the intestinal barrier, and influence immune cell differentiation and cytokine production.
- Dietary peptides can have immunomodulatory effects, impacting both innate and adaptive immune responses.

Conclusion

The gut microbiota is essential for intestinal function and immune defense. Dietary peptides and functional foods show potential in modulating the immune system and promoting intestinal health. Further research is required to fully elucidate the mechanisms and optimize the application of these dietary components for human health.

Fact Check

- The human intestinal microbiota has over 100 trillion bacteria. (Confirmed by text)
- Firmicutes and Bacteroidetes are the two most abundant bacterial phyla in the intestine, accounting for nearly 90% of all genetically diverse types. (Confirmed by text)
- The intestinal barrier system consists of four layers: immunological, mechanical, biological, and chemical. (Confirmed by text)
