Which type of food is NOT a source of insoluble fiber?

Insoluble fiber is a type of dietary fiber that does not dissolve in water and is beneficial for digestive health. It adds bulk to the stool and helps food pass more quickly through the stomach and intestines. Whole grain cereals, nuts, and wheat bran are all rich sources of insoluble fiber.

Cooked pasta, on the other hand, is not a significant source of insoluble fiber. While pasta is made from wheat, which contains some fiber, cooking it softens the pasta and alters its fiber structure, resulting in a reduction of fiber content overall, especially insoluble fiber. Therefore, cooked pasta is typically lower in fiber and does not contribute meaningfully to insoluble fiber intake compared to the other food options listed.
