Whole grains are unrefined, exceedingly nutritious, and contain more vitamins, minerals, and fiber than their lighter, whiter, and fluffier counterparts found in commercially packaged goods. In their raw form, grains contain a seed and a covering to protect the seed. With the advent of the Industrial Revolution and modern processing, it became easier to remove the germ and bran layers, making available to the general population white flours that were once reserved only for the rich.

Refined grains are frequently laced with additives and preservatives.
