Most consumers associate immunity with white blood cells, lymph nodes and pathogens. Many are surprised to learn that the gut and the bacteria living in it play a vital role in our immune function. Research suggests that over 70 percent of our body’s immune system resides in the gastrointestinal tract. Diet plays an important role in maintaining a healthy balance of good bacteria in our microbiome.
Whereas probiotic supplementation directly adds good bacteria to the gut, prebiotics help fuel the growth of good bacteria already in the gut. The increased presence of beneficial bifidobacteria is thought to support immunity by inhibiting the growth of pathogenic bacteria. This is important as clinical research shows that having imbalances of good versus bad bacteria in the microbiome may disrupt the normal functioning of our immune responses.
Maintaining a healthy diet rich in gut-healthy foods including prebiotic fiber can have a positive impact on your gut microbiome and help support a healthy immune system. Our prebiotic dietary fiber Arrabina, an arabinoxylan plant fiber extract, is proven to promote the growth of bifidobacteria.
