Whole Grains

Definition

Whole grains are grains that contain all three parts of the grain kernel: the bran, germ, and endosperm. They are considered healthier than refined grains, which have been processed to remove the bran and germ.

Scientific / Technical Definition

Whole grains retain the structural integrity of the kernel, consisting of the bran (the fiber-rich outer layer), the germ (nutrient-rich core), and the endosperm (the starchy component). This ensures that the grains contain essential nutrients such as fiber, vitamins, and minerals that are often lost in the refining process.
