Frequently Asked Questions
Dietary fiber is a type of carbohydrate found primarily in plant foods that supports normal digestive function. Fruits, vegetables, legumes, whole grains, nuts, and seeds are common sources of dietary fiber.
Dietary fiber is commonly categorized as soluble or insoluble fiber, and some fibers also have prebiotic properties. Different foods and supplements can contain different combinations of fiber types.
Soluble fiber dissolves in water and can form a gel-like material during digestion. Common sources include oats, barley, legumes, fruits, and certain fiber supplements.
Insoluble fiber does not dissolve in water and contributes to normal digestive function. It is commonly found in foods such as whole grains, vegetables, nuts, and seeds.
Prebiotic fiber is a type of dietary fiber that can serve as a food source for microorganisms in the digestive tract. Examples include certain types of inulin, fructooligosaccharides, and other fermentable fibers.
Daily fiber needs vary based on factors such as age and sex. Fiber can come from a combination of whole foods and, when appropriate, dietary supplements. Nutrition guidance and individual dietary needs should be considered when determining intake.
