Rice hurts the stomach by its stickiness.
Rice masses remove mucus from the stomach and duodenum as the sticky starch binds the sticky mucus, weakening the defense against acid and pepsin which may in turn cause heartburn and ulcer. Such unwanted effect can be avoided by taking enough water with rice meal as water converts rice masses into slurry.
