What does the term "whole grains" refer to?

The term "whole grains" specifically refers to grains that contain all parts of the grain kernel, which include the bran, germ, and endosperm. This complete structure ensures that the grain retains its natural nutrients, such as fiber, vitamins, and minerals, which are often lost during processing. Whole grains are essential for a healthy diet as they provide more fiber and nutrients than refined grains, which have removed parts of the kernel.

While processed grains typically lose some of their nutritional value, enriched grains have had certain nutrients added back after processing, but they still lack the complete structure of whole grains. Grains with added sugars do not fit the definition of whole grains; rather, they may contribute to excessive sugar intake and are generally not considered healthy choices. Thus, identifying whole grains as those that include all parts of the grain kernel is crucial for understanding their health benefits and differences from other types of grains.
