The two big differences are how they are processed and how healthful they are. The flour for both is made from wheat berries which have nutrient-rich parts. The bran (the outer layers), the germ (the innermost area) and the endosperm (the starchy part in between). Here is the difference, whole wheat is processed to include all three nutritious parts, but white flour uses only one which is the endosperm.
When you put them side by side in comparison, there is no contest. Whole wheat is much higher in fiber, vitamins B6 and E, magnesium, zinc, folic acid and chromium.
But of all these nutritional goodies, fiber is the star:
- In a 10-year Harvard study completed in 1994, men and
women who ate high-fiber breads had fewer heart attacks and strokes than those
whose tastes ran to bagels and baguettes.
- Simply switching from white to whole wheat bread can
lower heart disease risk by 20 percent, according to research from the
University of Washington reported in the April 2, 2003
issue of The Journal of the American Medical Association.
- Fiber has long been known to aid digestive health too.
- Fiber can help you lose or maintain weight because
eating fiber-dense wheat bread helps you feel full.
But a lot of white bread is enriched. Doesn’t that take
care of the nutrients lost during refining?
Nope. When flour is refined, it loses the most nutritious
parts of the grain—the fiber, essential fatty acids, and most of the vitamins
and minerals. In fact, about 30 nutrients are removed, but
by law only five must be added back (though others often
are): iron, niacin, thiamin, riboflavin and folic acid. There’s so little fiber
left after processing that you’d have to eat eight pieces of white bread to get
the fiber in just one piece of whole wheat bread.
Other foods besides whole grains have fiber and
nutrients. Can’t I just get what I need from them and still enjoy my dinner
rolls?
Whole grains provide health benefits that other foods
don’t. In a Harvard study of 75,000 nurses, those who ate at least three
servings a day of whole grains cut their heart attack risk by 35 percent and
were less likely to get into weight or bowel trouble. By contrast, those who
ate more processed foods—such as white bread, white rice and sodas—were more
than twice as likely to develop diabetes. “Science continues to support the key
role of whole grains in reducing chronic illnesses,” says Len Marquart,
professor of nutrition at the University of Minnesota and author of the first
health claim for whole grains approved by the US Food and Drug Administration.
How can I tell if bread is really whole wheat?
Color used to be a clue, but no more. Although white
bread is white because it’s been bleached, some dark bread has just had caramel
coloring added to it. Look for “whole grain” or “whole wheat” as the first
ingredient on the label. If any other ingredient is first, put the loaf back
and keep looking.
Is bread a vegan food?
Not usually. Many of the breads sold in grocery stores
contain non-vegan ingredients, including milk, eggs, honey, shortening or
whey—not to mention sodium stearyl lactylate, glycerides, emulsifiers, natural
flavorings, artificial flavorings and lactase, all of which may be derived from
animals. Vegans often have better luck at bakeries but still need to ask if the
bread pans are greased with animal fat. If you like to bake, you can make your
own bread. But if that doesn’t interest you, try Rudi’s Organic, Nature’s Path
or Brownberry’s—they all produce vegan breads available nationwide.
As I have said before, the only way to make any type of diet change is to start gradually like I did. I know more than anyone how hard it is to stick to something and then fail. But I never gave up. Try switching out your morning bagel for a whole wheat one every morning instead or try baking with whole wheat flour. Believe me, you will get used to the taste. Unlike the weather in Washington, with time it will taste better and white bread will be a thing of the past. I don't even think white bread tastes good anymore and if not for the taste, make the switch for your health.
