What food is a primary source of dietary fiber?

• A. Fish
• B. Whole grains
• C. Butter
• D. White rice

Answer: (B)

Whole grains are an essential source of dietary fiber, making them a crucial component of a balanced diet. Dietary fiber offers numerous health benefits, including promoting healthy digestion, helping to maintain blood sugar levels, and supporting heart health by lowering cholesterol. Whole grains, such as oats, brown rice, quinoa, and whole wheat products, contain both soluble and insoluble fiber, which contribute to these health benefits. In contrast, foods like fish, butter, and white rice do not provide significant amounts of dietary fiber. Fish is an excellent source of protein and omega-3 fatty acids but lacks fiber. Butter is primarily fat and contains no fiber. White rice, while a common carbohydrate source, has been processed to remove the bran and germ, which are rich in fiber, resulting in a much lower fiber content compared to whole grains. This distinction highlights the importance of whole grains as a key dietary source of fiber.
