Consumers are becoming more aware of the importance and benefits of a healthy gut. The association between the immune system and gut has sparked a new era of research and brought a new dimension to the food and drink industry. The balance of bacteria in the gut influences the balance of the immune system as the gut microbiota plays an important role in educating and modulating the immune system by stimulating the maturation and functionality of immune cells through their metabolites.
Probiotics can be used to regulate the innate and adaptive immune system of an individual.
- Probiotics improve gut barrier function that stops pathogens from entering the blood stream.
- Probiotics balance gut microbiome diversity which serves as a natural defence against pathogens.
- Probiotics support the function of white blood cells that play critical role in immune responses.
- According to the Synthetic and Systems Biotechnology Journal, consumption of probiotics significantly reduced the incidence of upper respiratory infection and flu-like symptoms.
