Frequent consumption of both vitamin E and the monounsaturated fats in black olives is associated with lower rates of colon cancer.
These nutrients help prevent colon cancer by neutralizing free radicals. Olive oil’s protective function also has a beneficial effect on ulcers and gastritis. Olive oil activates the secretion of bile and pancreatic hormones much more naturally than prescribed drugs, thereby lowering the incidence of gallstone formation. A cup of black olives also contains 17% of the daily allowance of fiber, which promotes digestive tract health by helping to move food through the system at a healthier pace.
This keeps any one part of the digestive tract from having to work too hard and supports the ideal balance of chemicals and populations of microorganisms required for a healthy digestive system.
