Final answer:
The food exchange least likely to be high in dietary fiber is white pasta, as it is made from refined grain. Whole grains such as whole wheat bread and brown rice are great sources of dietary fiber, as are fresh fruits. It's recommended to make at least half of your grain choices whole grains for better health outcomes.
Step-by-step explanation:
The food exchange least likely to be high in dietary fiber is d) White pasta. White pasta is typically made from refined flour, not whole grain, and during the refining process, the outer bran layer is removed, which significantly reduces its fiber content. On the other hand, whole grains, such as whole wheat bread and brown rice, as well as fresh fruits, are all excellent sources of dietary fiber. Whole grains retain their bran and germ, which provide fiber, and fruits often have fiber in their skins and pulp.
According to healthy eating guidelines, at least half of your daily grain intake should be whole grains, like whole wheat bread and brown rice, because they contain higher amounts of fiber that can aid in weight management and provide health benefits like reduced risks of chronic diseases. Dietary fiber is also present in legumes and vegetables, and is important for a healthy digestive system.
The bread/cereal/rice/pasta group is crucial for providing not only fiber but also B vitamins, minerals, and protein. To maximize health benefits, it's best to choose products that list whole grains as one of their main ingredients.
