Gastrointestinal  (GI) and Digestion 
Olive oil polyphenols help to free the digestive system from many pathogens found in foods. These antioxidants also slow down the digestive system’s acid production, lowering the chances of developing ulcers and other GI problems. Sitosterol, found in olive oil, lowers the absorption of cholesterol in the small intestine and stimulates the absorption of magnesium, iron and calcium. Olive oil aids digestion, relieves constipation, protects the intestinal tract and improves bile and liver functions. It lowers the chance of developing gallstone by cleansing the gall bladder.
