The Whole Wheat Kernel
A whole grain is any grain (not just wheat!) which maintains all three of its parts. Keeping all three parts of the grain means you keep all of the beneficial components the whole grain has to offer. The three parts are called the bran, the germ, and the endosperm.
This is the tough and fibrous outer shell of the wheat kernel. This was created by nature to actually protect the interior of wheat berry from pesky insects and the elements so the kernel can sprout and grow into a new plant. It contains important antioxidants, B vitamins and fiber.
This is the largest part of the grain, which is a good thing too because it is the food supply for the plant when it first starts to grow before it has well established roots and leaves for nourishment. This is the starchy part of the grain where most of the carbohydrate can be found. It also provides proteins and small amounts of vitamins and minerals.
This is the most important part of the grain in regards to its development because this is the embryo that will transform into a plant. This is also the only portion of the grain that contains healthy fats. It also contains B vitamins, some protein, and minerals.
