What specific prebiotic fibers found in Vidalia onions serve as fuel for beneficial bacteria in the large intestine?
Answer
Inulin and Fructooligosaccharides (FOS)
The digestive wellness benefits of Vidalia onions are strongly linked to their content of specific types of fiber classified as prebiotic fibers. These components, namely Inulin and Fructooligosaccharides (FOS), are noteworthy because they are not digested in the upper gastrointestinal tract. Instead, they pass intact into the large intestine, where they become a selective food source, or fuel, for the resident beneficial bacteria, known as probiotics. Nourishing this gut microbiome is essential, as a healthy balance is correlated with improved digestion efficiency, enhanced nutrient absorption across the intestinal lining, and a strengthened general immune function.
