Which of the following is true about dietary fiber?

Dietary fiber is known for its role in maintaining a healthy weight, making this choice accurate. Fiber contributes to the feeling of fullness after eating, which can help control appetite and reduce overall calorie intake. Additionally, high-fiber foods, such as whole grains, fruits, and vegetables, often have lower energy density, meaning they provide fewer calories relative to their volume, which can also support weight management.

While fiber does provide some health benefits, it does not function as a direct source of energy like carbohydrates or fats because fiber is not fully digestible by the human body. Therefore, it does not contribute significantly to caloric intake, distinguishing it from other macronutrients.

The assertion that fiber is a major source of fats is incorrect since fiber is a type of carbohydrate and contains no fat content. Similarly, stating that fiber is only found in fruits overlooks its presence in many other food sources such as vegetables, legumes, and whole grains. Thus, a comprehensive understanding of dietary fiber reveals its significant role in promoting satiety and assisting in weight management rather than providing energy or being limited to specific food groups.
