Beyond fibre: Gut health, prebiotics and immunity

The connection between gut health and immunity is becoming increasingly apparent through scientific research. Studies have shown that a healthy gut microbiome is essential for a strong immune system. 

Caroline Perreau, nutrition and health research manager at Roquette, explained: “The gut microbiome contains millions of beneficial bacteria that help to regulate the immune system. These bacteria produce short-chain fatty acids (SCFAs), which serve as an energy source for the cells lining the gut and help to maintain the integrity of the gut barrier, barrier which is a crucial part of the immune system.”

Different factors can influence the gut microbiota composition and its environment like the age, the lifestyle, the medications, and the diet, especially the fibres and/or the prebiotics.

Most of the soluble fibres – like NUTRIOSE soluble fibre – are used as a substrate in the colon to be fermented by the bacteria. They are not digested by the body and serve as food for the beneficial bacteria in our gut. These beneficial bacteria play a crucial role in maintaining a healthy gut microbiome and promoting overall health.

“Part of prebiotics are soluble dietary fibres that can modulate a selection of bacteria and demonstrate linked health benefits. All fibres are not prebiotics, and all prebiotics are not fibres. The health benefits of fibres are not the same for all fibres,” said Perreau.

In short, prebiotics can help to promote a healthy gut microbiome by providing food for beneficial bacteria. And a healthy gut microbiome is essential for a strong immune system.
