Is mostly indigestible but it is still important for us to eat what purpose does it serve?

Indigestible substances, primarily dietary fiber, play a crucial role in maintaining digestive health. They help regulate bowel movements, prevent constipation, and promote a healthy gut microbiome. Additionally, fiber can aid in lowering cholesterol levels and stabilizing blood sugar, contributing to overall health and reducing the risk of chronic diseases. Thus, while we cannot digest fiber, its benefits are essential for our well-being.
