1. Inulin is a soluble dietary fiber that is not fully digestible, playing a vital role in enhancing digestive health and supporting intestinal well-being.

2. As a prebiotic, inulin promotes the growth of beneficial gut bacteria and is commonly added to various food products for its health benefits.

3. When fermented by gut microbiota in the colon, inulin produces short-chain fatty acids (SCFAs), which provide energy to intestinal cells and influence immune function.

4. Inulin and its metabolites may help prevent diseases such as type 2 diabetes, inflammatory bowel disease, chronic kidney disease, and certain cancers through their immunomodulatory effects.

5. The USDA recommends a daily fiber intake of 25-36 grams, while inulin is recognized as generally safe by the FDA, with an effective daily intake of 5 grams and a maximum of 15-20 grams.
