100% Whole Wheat and 100% Whole Grain do not necessarily mean the same thing. The main difference is the presence of the wheat germ. Due to milling processes, 100% Whole Wheat products may not include the germ, whereas 100% Whole Grain products always include the germ. If you are unsure as to whether or not the product is Whole Grain, check the ingredient list to see if wheat germ is included.
