The Role of Dietary Peptides and the Gut Bacteria in Maintaining Intestinal and Homeostatic Balance

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.
