What are Examples of Dietary Fiber Foods?

Dietary fiber, often referred to as roughage or bulk, is an essential component of a healthy diet. Unlike other nutrients, fiber is not digested by the body but passes through the digestive system, aiding in various bodily functions like promoting digestion, regulating blood sugar, and reducing cholesterol. Fiber is primarily found in plant-based foods, and consuming a diet rich in fiber has been linked to numerous health benefits, including improved gut health, weight management, and lower risks of certain chronic diseases. Here’s a closer look at examples of high-fiber foods:
