Bifidogenic effect of prebiotics: a nutritional strategy for gut microbiome modulation

Popis výsledku v původním jazyce

Bifidobacteria are an important group of commensal bacteria within the human gut microbiota and are considered among the dominant microbial taxa in infants. Although their abundance tends to decline with the ageing of the host organism, their presence in the intestine remains associated with a range of beneficial effects that support human health. As saccharolytic anaerobes, bifidobacteria primarily colonise the distal parts of the gastrointestinal tract, where they produce short-chain fatty acids, antimicrobial compounds, and vitamins. Their metabolic activity involves cross-feeding interactions with other microbes, inhibition of pathogens, and modulation of the host immune system. To support bifidobacterial persistence, various strategies are being explored. One promising approach is the use of prebiotic substances, which may be incorporated into the diet either naturally or through dietary supplementation, in both endogenous and dietary forms. These substances (typically carbohydrate-based) are selectively utilised by host microorganisms and confer health benefits at various sites of action. To be classified as prebiotics, they must meet several essential criteria as defined by the International Scientific Association for Probiotics and Prebiotics (ISAPP). Common examples include human milk oligosaccharides (HMOs), galacto-, fructo-, xylo-, soybean-, pectic-, and mannan-oligosaccharides. In recent years, additional candidates such as novel plant-derived oligosaccharides, polyphenols, and ß-glucans have also gained attention. Bifidogenic prebiotics positively modulate bifidobacterial abundance and play an increasing role in the modern nutrition of the human population. Their inclusion in the daily diet may contribute to disease prevention, enhancement of immune function, improved digestion, and overall health maintenance. Nevertheless, the bifidogenic response to prebiotics may vary depending on the host’s age and microbial background, both of which must be considered. Thus, the ongoing search for novel prebiotic compounds with selectivity for typical bifidobacterial species is desirable and holds great promise for targeted modulation and long-term maintenance of gut microbiota homeostasis.
