What type of soluble fiber, recognized as a prebiotic, is supplied by onions and acts as food for beneficial gut bacteria in the colon?
Answer
Inulin
Onions serve as a good source of inulin, which is classified as a soluble fiber and functions specifically as a prebiotic. Prebiotics are crucial components of digestive health because they are non-digestible by human enzymes and pass intact through the upper digestive tract. Once they reach the colon, they become the primary food source for the population of beneficial bacteria residing there. By nourishing these good microbes, inulin promotes the multiplication of favorable bacteria, leading to a more diverse and balanced gut microbiome, which in turn supports better nutrient absorption and overall digestive wellness.
