What type of fiber is known for promoting water retention in the intestines?

The type of fiber that promotes water retention in the intestines is soluble fiber. This type of fiber dissolves in water to form a gel-like substance, which helps to increase the viscosity of the intestinal contents. As soluble fiber absorbs water, it can slow down digestion and can lead to a feeling of fullness, which can be beneficial for weight management. Additionally, by retaining water, soluble fiber can help to soften stool, making it easier to pass and potentially alleviating constipation. This water retention also aids in the overall digestive process and can help regulate blood sugar levels by slowing the absorption of glucose. Therefore, soluble fiber plays an essential role in promoting healthy bowel function and overall digestive health.
