I used to be someone who was a complete advocate for white breads/white flour. I liked the taste, I liked the texture, and I despised anything with the mention of whole grain involved. I have since turned coat, and joined the whole grain team.
What is the difference between whole grain and that used in "white" breads? Whole grain means that it contains all three parts of the grain (the bran, the germ, and the endosperm). The flour used in white breads and other "white flour" products contain only the endosperm. Lets talk about the various parts of the grain.
- Bran - the bran is the outer shell of the grain and contains fiber, B vitamins, trace minerals, and phytochemicals (many laboratory studies conclude that phytochemicals help prevent certain types of cancer).
- Germ - the germ is what nourishes the grain and contains anti-oxidants, B vitamins, healthy unsaturated fats, and Vitamin E.
- Endosperm - the largest part of the grain. This is what contains the carbohydrates, and protein. Essentially it contains the energy.
So, as you can see, basically enriched flours do not contain the bran or the germ, so for the most part they just contain energy, and are of little nutritional value. That is the reason they are enriched. The enrichment process puts back some of the vitamins that are taken out in the process of creating the white flour.
Enriched flour, although it has had some of its nutritional content returned, is still lacking in many areas. The biggest and most gaping hole in the defense of enriched flour is that compared to whole grain bread it has relatively no fiber. Fiber is a very important part of the diet for a number of reasons.
For the most part, there are two types of fiber. There is Insoluble fiber which helps prevent hemorrhoids, constipation, diverticulosis, as well as helps protect against colon cancer. Insoluble fiber is found in whole grain breads, pastas, cereals, brown rice, and popcorn. Then there is soluble fiber which is found in barley, oatmeal, and rye. Soluble fiber reduces the risk of heart disease, as well as it helps lower cholesterol (reminds you of a Cheerios commercial eh?). It also helps the absorption of glucose, which stabilizes blood sugar levels.
On top of providing the benefits just above, fiber helps you feel full faster, which can equate eating less. This is a really good thing considering that most Americans eat too much food, period. Savor the flavor, not the time you spend in the bathroom, or on a gurney after your next bout of cardiovascular or digestive problems.
In my opinion, just for the benefit of the fiber alone is enough to consider joining the whole grain team. On top of it though, you receive those vitamins I previously mentioned inserted naturally, vs. after they have been processed out.
Now I understand that many people are used to enriched flours, and prefer them over the "graininess" of whole grains because of their smooth, supple nature. Conversion to whole grain takes work, but in the long run is worth it. Since my conversion, I have come to enjoy whole grains more than I do enriched, I have come to like their texture. I enjoy the heft, the body of a good whole grain loaf, and the smell of it fresh just knocks the socks off of that pasty enriched tripe.
For those of you who wish to make the conversion, but cannot take on the texture of whole grain yet, do not despair. There are a few products out there for you. One in particular I have found is manufactured by Sara Lee. It is called Soft and Smooth, 100% Whole Wheat. Make sure you get the right one, there are some that are fairly close in title, but are not whole wheat (check the ingredients list, if it doesn't say Whole Wheat Flour, forget about it). Soft and Smooth is exactly as its titled. It is very comparable to Enriched White Flour Bread in texture, but with the benefit of whole wheat.
There has been some progress of developing a white grained whole wheat flour, and you can find it in some places. It also is comparable in texture, but whiter in color.
Whole grain flour is much better for you, so I encourage you to start using it. There are a number of things that enriched processed flours are better for in theory, which are mainly dessert items. Desserts most often require a smoother texture, and if that is the case, then it may be better suited. Remember, dessert is not intended to be your main course, and that is how it should be for enriched flour. But, if you are one of those people who feel that dessert should be the most common item of your consumption, I wish you a short and happy life.
