Q. Vegetables and fruits should be a part of our diet because they stimulate _____:
Answer: Peristalsis
Notes: Vegetable and fruits should be a part of our diet because they stimulate peristalsis. Dietary fiber found in whole fresh fruits and vegetables and whole grains stimulates peristalsis, flushing out fats and waste. Gas-producing foods like broccoli and cabbage also stimulate peristalsis. Drinking plenty of fluids is important because it keeps stools soft and easy to pass.
