What does "whole grain" mean?

"Whole grain" refers to grains that contain the entire grain kernel, which includes the bran, germ, and endosperm. This definition is crucial because whole grains retain their natural nutrients, fiber, and beneficial compounds that are often lost in the refining process. The bran is the outer layer that provides fiber and essential nutrients, the germ is the part that can sprout into a new plant and contains healthy fats, vitamins, and minerals, and the endosperm is the starchy part that provides energy.

Consuming whole grains as part of a balanced diet is associated with numerous health benefits, including improved digestion, better heart health, and a reduced risk of certain chronic diseases. Understanding the components of whole grains helps individuals make informed dietary choices that can enhance their overall health.
