What are the two subgroups grains are divided into?

Grains are divided into two primary subgroups: whole grains and refined grains. Whole grains retain the bran, germ, and endosperm, making them rich in fiber, vitamins, and minerals. This whole structure contributes to the nutritious value of these grains and is beneficial for health, helping to reduce the risk of chronic diseases.

Refined grains, on the other hand, have been milled to remove the bran and germ, which reduces their nutritional value. While this process creates a more palatable product with a longer shelf life, it also strips away many of the beneficial nutrients found in whole grains. Understanding these distinctions is important for making informed dietary choices that support overall health.
