What Fiber Does

Fiber is a plant-based carbohydrate that supports digestion and helps prevent constipation.

Fiber Adds Bulk

It adds bulk to your diet and can help you feel full faster, according to MedlinePlus.

Food labels may list soluble fiber or insoluble fiber; both are types of dietary fiber with health benefits.

Good sources include whole grains, nuts and seeds, fruits, and vegetables, offering several plant-food choices.

Adding dietary fiber too quickly can cause gas, bloating, and cramps, so MedlinePlus advises increasing it slowly.

MedlinePlus says most Americans do not eat enough dietary fiber, making fiber sources useful to recognize.

For questions about constipation, digestive discomfort, or diet changes, contact a health care provider for individual guidance.
