Description
Functions in the Body
Prebiotic fiber is a nondigestible, soluble fiber derived from carbohydrates like oligosaccharides, playing an essential role in digestive health by nourishing beneficial gut bacteria, known as probiotics. By promoting the growth of these good bacteria, prebiotics help maintain a balanced gut microbiota, reduce harmful pathogens, and support immune function. During fermentation in the digestive tract, prebiotic fiber produces short-chain fatty acids like butyrate, which bolster gut lining health, improve nutrient absorption, and enhance digestion. Prebiotic fiber is also known to boost calcium absorption, reduce inflammation, and lower the risk of chronic diseases like heart disease and diabetes. Regular consumption of prebiotic-rich foods supports long-term gut health, immune resilience, and digestive wellness, making it an important part of any diet aimed at improving overall well-being.
Deficiency Symptoms
A lack of prebiotic fiber can result in constipation, weight gain, loose stools, stomach pain, and diarrhea.
Synergy & Antagonism
Prebiotic fiber works synergistically with probiotics to promote gut health, improve digestion, and enhance the absorption of nutrients. No well-documented antagonistic interactions exist.
