Insoluble fiber is a type of dietary fiber that does not dissolve in water, playing a key role in promoting digestive health. It helps prevent constipation, supports bowel regularity, and may reduce the risk of chronic diseases like colorectal cancer. Found in whole grains, vegetables, and fruits with skin, insoluble fiber adds bulk to stool, aiding smooth digestion.
What is Insoluble Fiber?
Insoluble fiber, also known as non-soluble fiber, is a type of dietary fiber that does not dissolve in water. It is primarily found in plant-based foods and plays a crucial role in maintaining digestive health. Unlike soluble fiber, insoluble fiber does not break down in the digestive system and instead adds bulk to stool, helping it move through the intestines more quickly. This helps prevent constipation and supports regular bowel movements. Insoluble fiber is found in whole grains, vegetables, fruits with skin, nuts, seeds, and legumes. It is essential for maintaining a healthy gut and preventing digestive disorders. By acting as a natural laxative, insoluble fiber helps cleanse the gastrointestinal tract and promotes overall digestive well-being.
