Oil It Up

If the human body is a well-oiled machine, it’s no wonder that consuming extra-virgin olive oil can help keep your blood sugar in check.
 

In a Spanish study, people who ate bread drizzled with olive oil experienced a significantly smaller spike in blood sugar than they did after eating bread slathered with butter or margarine. Props go to the oil's payload of monounsaturated fat, which signals your small intestine to produce a protein that boosts insulin. Drizzle olive oil on a baked potato, or dress a sandwich with olive oil and vinegar instead of mayo.
