TOTAL DIETARY FIBER?\nTo summarize, while crude fiber has traditionally been used to declare the fiber content in pet\nfood, it primarily accounts for only insoluble fibers, omitting important soluble fibers. Total\ndietary fiber includes both soluble and insoluble fibers, providing a more comprehensive and\naccurate representation of the fiber sources included in pet food. Therefore, consumers may\nsee a higher value for fiber on their pet food label. This update to pet food labels enhances the\nnutritional information available to consumers.\n\nFigure 2. Crude fiber captures only a limited subset of insoluble fiber, whereas total dietary fiber encompasses the full range\nof both soluble and insoluble fiber components.\n","sources":["US FDA / USDA APHIS — WHAT IS CRUDE FIBER VS.
