The fibre (roughage) content of food, whilst essentially non-nutritive, is very important. The fibre content absorbs moisture, thus making the food more uniform in texture, and easier to digest. Further, one of the important function of your bowel is to recover water from the feces, such that this important material is not squandered. The presence of fibre makes this water easier to extract. [If your bowel is damaged by disease, this water extraction process is often interfered with, producing the unpleasant liquid motions.]
