                                According to the National Institutes of Health, a grain remains a whole grain as long as its key components—the bran, germ, and endosperm—are retained in their original proportions. This brings into question the common belief that whole wheat is unprocessed, as it often undergoes significant mechanical changes from its harvested form.
