Dietary Fiber

Dietary fiber, often called fiber, is the part of plant-based foods that the body cannot digest or absorb. It includes components like cellulose, hemicellulose, and pectin. Fiber is naturally found in fruits, vegetables, whole grains, and legumes.

Fiber is added to foods to increase their nutritional value, particularly for fiber content. It can also act as a bulking agent, improving texture and mouthfeel. Manufacturers often add fiber to baked goods, breakfast cereals, snack bars, and some dairy products.

Dietary fiber is recognized as a beneficial component of the diet. The FDA considers it a nutrient and allows health claims about its role in reducing the risk of certain cancers and heart disease when consumed as part of a diet low in fat, cholesterol, and sodium. Major health organizations like the WHO and EFSA have also recognized the importance of fiber for digestive health and overall well-being. While generally considered safe and beneficial, very high intakes can sometimes lead to digestive discomfort.
