Dietary Fiber Intake Protects against Diet-Induced Obesity and Metabolic Syndrome

Zou et al found the fermentable fiber inulin restored gut health and protected mice against metabolic syndrome induced by a high-fat diet by restoring gut microbiota levels, increasing the production of intestinal epithelial cells and restoring IL-22 expression, which prevented gut microbiota from invading epithelial cells.
