What is whole grain ne demek?

Whole grain refers to any cereal grain that still contains the endosperm, germ, and bran, in contrast to refined grains which retain only the endosperm portion. Whole grains can include wheat, rice, corn, oats, barley, quinoa, rye, and more. They are an important source of complex carbohydrates, fiber, vitamins, and minerals. Consuming whole grains has been linked to lower risk of chronic diseases such as heart disease, diabetes, and certain types of cancer. It is recommended that at least half of the grains we consume should be whole grains.
