First things first, the terms “whole wheat” or “whole grain” are very specific. As the Nutrition Diva writes:
Whole grain products contain all the parts of the grain: the germ, which is rich in essential fatty acids and b-vitamins; the endosperm, which is mostly starch; and the bran, which, of course, is high in fiber. In products made with refined grains, on the other hand, most of the germ and bran have been removed, leaving the starchy endosperm, which is the least nutritious part of the grain.
The term “multigrain,” on the other hand, simply means that a variety of different grains were used. And many (if not all) of those grains may be refined – and thus, much less nutritious. To know for sure, simply examine the ingredients on the packaging. Look for the word “whole” before the grains listed to get a better idea of the nutritional value.
Bottom line: If you’re looking to include bread as part of your healthy diet, opt for whole wheat. While multigrain bread may sound appealing, unless it’s made with whole grains, it can have the same nutritional value as white bread.
