What Are Whole Grains?
You must have already heard countless advertisements boasting about their products’ whole grain content, but what exactly are whole grains, and why are they better than refined carbohydrates?
Whole grains refer to the unprocessed seeds of cereal plants, like barley, corn, rice, rye, quinoa, and wheat². Whole grains retain all its three parts:
- Bran – It is the thin, outermost layer rich in insoluble fiber, phytochemicals, and B vitamins.
- Endosperm – It is the thickest, central part rich in starch.
- Germ – It is the smallest part rich in protein and healthy fats.
Now, many manufacturers choose to “refine” whole grains into white bread, white pasta, white rice, etc. The process results in a finer texture and longer shelf life but removes the bran and the germ and the nutrients that come with them.
