A new study shows the power of beneficial bacteria in the gut to support a healthy immune system. People with more of certain kind of bacteria in GI tract have significantly lower risk of infection. These bacteria turn fiber into an immune boosting fatty acid called butyrate. Individuals who had 10% more of this bacteria faced a 15%-25% lower risk of infection. These findings suggest that eating foods high in fiber or taking probiotics can help protect against infections beyond the gut (for example, the lung or bladder). A person’s age, overall health and history of antibiotic use can also affect the composition of bacteria in the gut.
