The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
Foods That Stimulate Peristaltic Motion. Dietary fiber stimulates peristalsis. Muscles that line your esophagus, stomach, small intestine and colon contract and relax in a rhythm that produces a wavelike motion. This movement, called peristalsis, pushes food through the length of your digestive tract. Any food you eat stimulates nerves, which trigger peristaltic action in the muscles.
