Olive oil is very well tolerated by the stomach due to its high oleic acid content. The sphincter which separates the stomach from the oesophagus is less affected by olive oil than any other fat. It also slows down acid overproduction in the digestive system thereby diminishing the potential for ulcers and other gastrointestinal problems. Finally, because olive oil stimulates bile secretion and regulates the emptying of the gallbladder, it can reduce the risk of developing gallstones.
