Cara's best choice for sticking with her health goals would likely be to choose a whole grain option over a refined grain option. Whole grains, such as quinoa, brown rice, or whole wheat bread, are a better choice because they contain all parts of the grain, including the bran, germ, and endosperm. This means they have more fiber, vitamins, and minerals than refined grains, which have had the bran and germ removed. Whole grains have been linked with a lower risk of heart disease, diabetes, and certain cancers, as well as improved digestion and weight management.
