What I Learned About Whole Grains and White Flour
My wife and I try to eat whole grain breads even though I grew up on Wonder Bread. You know - the one with the colored dots on the white bag that "helps build strong bodies eight ways?" But my girls? They'll only eat white bread. We've tried, but the only way they'll let whole grain bread touch their lips is when I make French toast out of it without their knowing!
Whole grains are better for us. I think most of us would agree with that statement. But, why are they better for us? I thought that I knew, but I wasn't really sure. I did some research and thought I would share it with you so we can all be better informed. Maybe one day my girls will read this and realize that sometimes Father and Mother really do know best!
First up: Wheat
It's the grain that makes up the vast majority of bread and pasta. I love bread and pasta, so I wanted to know what the advantages of whole grains are in these foods. Each grain of wheat is made up of three basic parts: the bran, the endosperm and the germ. The bran is the outer coating of the grain, the endosperm is made up of starches and is there as reserved food for the plant that would grow if the wheat were planted. And that potential plant is called the germ.
Any food that has been altered from its original state has been processed, so to be nitpicky, all wheat flour is processed, but the more steps to the process, the more refined the product is. When they make whole wheat flour, the entire wheat grain--bran, endosperm and germ--are milled into flour.
White flour is made (in layman's terms) by first flattening the grains and then shaking out the bran and germ before milling the endosperm into flour. Since there are more steps to making white flour, it is a more refined product than whole wheat flour.
So, is this a bad thing?
It depends on what you want to do with the flour. White flour is great for when you want to make light and airy things like cakes and soft rolls. Since it contains sharp little pieces of bran, batters and dough made with whole wheat flour don't bake up as light (shards of bran can cut gluten strands), but whole wheat flour contains insoluble fiber and B vitamins, both of which are essential to our health and are the nutrients that are found in the bran and germ.
With white flour, we just get energy from the endosperm, which is mostly composed of carbohydrates that are easily converted to glucose for energy. After all, it's food for the little plant that would have grown, and baby food is always easy to digest! But, without the bran and germ to slow absorption into our systems, eating too much white flour can cause our blood sugar to spike.
Is whole wheat flour more nutritious than white flour?
Here's the nutritional breakdown for both types of flour from Self Nutrition Data:
Nutritional Values (per cup) Whole Wheat Flour White Flour
Calories/From Fat 407g/19g 455g/10g
Fat (Saturated) 2g 1g
Transfat 0g 0g
Cholesterol 0mg 0mg
Sodium 6mg 2mg
Carbohydrates 87g 95g
Fiber 15g 3g
Sugar 0g 0g
Protein 16g 13g
What do we do with this information, though? I mean, it looks fairly even to me. The whole wheat flour contains a bit more fat, fiber and protein, but otherwise, why is the whole wheat better?
When you look at the amount of vitamins and minerals in the two flours, it looks like the enriched white flour beats the whole wheat, hands down! But what we all need to understand is that the "enriched" part of the name means that all the natural vitamins and minerals contained in the germ have been stripped away along with the germ, so the enriching means that they add the nutrients back in.
The whole wheat flour, on the other hand, contains all the natural vitamins and minerals that are contained in the germ, as well as the fiber from the bran. And for my money, natural is better. One day, my girls will understand this, I hope. For now, we get whole grains into them in other ways.
Other Whole Grains
As I just mentioned, whole wheat flour is processed. If you're looking for a less processed form of wheat, think about trying wheat berries, which are whole wheat kernels, or cracked wheat, which is exactly what it sounds like. Both are hearty, nutty, nutritious and filling.
While white rice has been stripped of its bran coating very much like white flour, brown rice is a wonderful whole grain that the whole family really enjoys. It does take a bit longer to cook than white rice, but the subtle nutty flavor and slightly chewy texture are both worth the wait.
Rice - In our house, we have started to combine white rice and brown rice in equal amounts and no one seems to notice it is even in there. Every once in a while one of the girls will say, "Why is this piece of rice darker than the other white rice?" and then go on and eat it. I'll see if I can change the ratio over time until we are all just eating brown rice.
Oatmeal makes for a warm and filling breakfast, but the same rule applies: the less refined it is, the better for you it is. Microwavable packets of oatmeal are convenient, but to get the full benefit of the whole grain, you'll want to skip the convenience factor and buy steel cut oats.
These are oats that have been dried, toasted and then cut into pieces with nothing removed. Whole grains, but in pieces! A happy medium would be the standard rolled oats (not quick cooking) which have been steamed to make them softer and then pressed flat through a roller.
Barley (not the pearled kind, which has been steamed and scrubbed of most of the bran) is also a pretty common whole grain. I grew up enjoying it in canned vegetable beef soup, but there are many ways to enjoy barley, including casseroles, pilafs, risotto-style and in soups like when I was a kid.
Less well-known, at least to me, but equally as good for you are millet, quinoa, teff, and spelt among others.
Before you get overloaded wondering how to add all these whole grains to your diet, let me assure you that cooking them is easy. If you can cook rice, you can cook any of these grains, as the procedure is all the same.
For every cup of whole grain, use two cups of water or broth (seasoned to your taste). Bring to a boil in a pot, put the lid on, turn down the heat to a simmer and leave them alone until all the water is absorbed. Depending on the size of the grain, this could take anywhere between fifteen and forty minutes.
So, when considering nutritious foods for your family, especially if you or your kids don't like whole wheat or whole grain bread, try introducing some of these other grains into your diet. Most of us don't get enough natural fiber into our diets, so eating whole grains allows you to get more fiber through the bran. As well, many of these grains contain soluble fiber which has been shown to have a positive effect on both blood sugar and cholesterol levels.
The Cost of Grains
In case you are wondering how much these different whole grains cost, here's a handy chart I put together to give you an idea, although prices in your area may vary. I found these prices from a bulk foods supplier. Each price is per pound, just for comparison's sake.
Grain Organic Price per Pound Conventional Price per Pound
Wheat berries $3.32 $0.68
Cracked wheat $1.04 $1.46
Steel-cut Oats $3.49 $2.66
Barley $3.28 $2.85
Millet $3.57 $3.00
Quinoa $6.02 $3.41
