High-fiber diets are also beneficial for certain gastrointestinal conditions. Fiber slows the movement of food and acidic fluid from the stomach to the intestines. It may help people with duodenal ulcers by reducing the exposure of the small intestine to stomach acids. Get your digestive system back on track: It's a good idea to take digestive plant enzymes with every meal. This will help gas and bloating, as well as to help bowel movements become more frequent. Another technique is to take hydrochloric acid supplements with meals. These will help to alleviate digestive problems. And again, don't dilute your stomach acid or enzymes by drinking liquids during your meal.
