The Anatomy of a Wheat Kernel
A wheat kernel consists of three parts: the bran, endosperm, and germ. The bran is the outer layer, rich in fiber and vitamins. The endosperm is the largest part, providing starches and protein. The germ is the embryo and is nutrient-dense with healthy fats, antioxidants, and vitamins. Whole wheat includes all three parts, making it more nutritious than refined products which only use the endosperm.
How Processing Affects Nutritional Content
Refined flour removes the bran and germ, reducing nutrients and fiber but increasing shelf life. Whole wheat flour uses the entire kernel or reincorporates the bran and germ.
The Health Benefits of Wheat Germ
The germ adds significant nutrients like B vitamins, minerals, antioxidants, and healthy fats to whole wheat.

What to Look For When Buying Whole Wheat
To ensure products contain wheat germ, look for labels like "whole wheat" or "100% whole wheat". "Wheat flour" or "multigrain" may not include the germ. Common whole wheat products include bread, pasta, flour, bulgur, and cereal.
Conclusion: The Indispensable Germ
Whole wheat includes wheat germ because it uses the entire kernel. This is key to its nutritional value. Look for '100% whole wheat' labels to get the benefits of the whole kernel.
