In a free fall environment, food does not remain on a plate as it would on Earth, and liquids do not remain in cups; things float away. Therefore, food and drinks in space have to be consumed from containers that the astronaut can control, and that prevent the food from floating away. Swallowing, however, takes place in the normal manner. The human body does not depend upon gravity to make food travel through the alimentary canal; there are muscular contractions called peristalsis which move the food along, and they work just as well in free fall (provided that the astronaut is not suffering from nausea or space sickness, which is another hazard).
