how does fiber work in your diet

Most fiber is, like other carbohydrates, made up of many glucose molecules. However, fiber does not break down into glucose before it gets to the colon, and often not even there. Even so, fiber does have effects on our digestion all along the way and has other benefits to our bodies. Here’s what fiber does in our bodies. In the stomach, fiber is bulky, so it tends to make us feel full. However, insoluble fiber moves out of the stomach fast unless there is fat, protein, or soluble fiber to slow it down. Soluble fiber, especially the vicious types that hold onto water, will slow down stomach emptying, especially when eaten with lots of fluid and some fat. This is at least partly why soluble fiber tends to decrease the glycemic effect of a meal—the contents of the stomach more gradually enter the small intestine, and from there, the blood.

You know you’re supposed to eat lots of fiber — but why? And can you get too much of a good thing? We hear a lot about the health benefits of protein — but all too often, the pros of eating fiber go overlooked. Dietary fiber, found particularly in vegetables, fruits, beans, and whole grains, helps to keep bowel movements regular. Too much fiber may result in loose stools, bloating, or even diarrhea. Dietary fiber is the term used to describe the combination of both insoluble and soluble fibers. Soluble fiber is the form of fiber that dissolves in water. Examples of foods that contain soluble fiber include fruits, oats, legumes and barley.
