Fine tuning the Immune System…

Feedback-fiberThere are many benefits to a fiber rich diet. Reduced risk of diabetes, hypertension etc. But why? Instead of feeding us directly what fiber does is feed our intestinal bacteria. For proper digestion, we need to call on enzymes for assistance to break down a nutrient into its smaller components. What we classify as the indigestible part of a plant called fiber is actually digested and used as nourishment for the microbiome (healthy gut bacteria) that line our intestinal track. To test this theory scientists at Georgia State University separated mice into two groups. One group was placed on a high fiber diet and the other on a low fiber, high fat diet. After examining the feces from the two groups they discovered that the low fiber, high fat group had a collapse in their microbiome population, their intestines started to narrow and their inflammation level increased. It seems that each plant and fruit provides a different fiber which in turn feeds a different population of bacteria in our gut. I guess there is truth to the saying “an apple a day……”
