High-fat and fried food

Worst

Both high-fat and fried food can overwhelm the stomach, resulting in acid reflux and heartburn. "The body can only handle so much at one time," says Jessica Anderson, RD, a diabetes educator with the Texas A&M Health Science Center Coastal Bend Health Education Center, in Corpus Christi.

High-fat food also can result in pale-colored stool, a phenomenon called steatorrhea, which is essentially excess fat in the feces. A lot of people with irritable bowel syndrome need to stay away from foods high in fat, she says, including butter and cream because they can cause digestive problems.
