A healthy digestive system allows you to have regular elimination after eating. If your digestive system is not healthy, you may experience signs such as bad breath, food intolerances, acid reflux, irritable bowel syndrome, constipation, rashes and skin irritations, and unusual weight fluctuations. Collard greens, high in both water and fiber, can help curb some of these issues if eaten regularly. One cup of collards gives you about 8 grams of fiber; fiber helps prevent constipation, another indication your body is struggling with waste elimination. Many people choose over-the-counter laxatives, but collard greens could be an effective and natural alternative.
