White bread - Properties and differences with the integral Is it wrong

For centuries, white bread was considered a delicacy that only aristocrats could afford. Whereas the peasants had to be content with cereals and bakery products made from low-quality grains.

This article describes the properties of white bread and its differences in nutritional properties with whole wheat.

Nutritional properties of white bread

From a nutritional point of view, white bread is a high-calorie, low-nutrient product.

The white bread making process begins by grinding the wheat grain and sifting it. In this process the shell is removed: the bran. In addition, the wheat germ content is reduced. The kernel of the wheat grain rich in vitamins, minerals and vegetable fiber.

Therefore, if refined white flour is used when making bread, there are practically no contributions of proteins, vitamins or minerals. (1) This also applies to most mold or industrial blank breads.

Also, white bread may contain other ingredients like bleaches. These compounds are responsible for giving the flour its typical white color. As well as preservatives, to increase its shelf life.

The nutritional properties in 100 g of white bread:

  • 50 g are carbohydrates, of which:
  • 2-3 g are dietary fiber
  • 4-5 g azúcares
  • 40 g starch
  • 8 g protein (more than half is gluten)
  • 3 g fat

Differences of whole wheat bread with white

The glycemic index of white bread is about 90-100 units, one of the highest. While that of the integral is around 50 units; a big difference. This is why the choice of whole wheat bread over white is essential in people suffering from diabetes.

As well as whole wheat bread, it has a greater contribution of vitamins and minerals. This is because the whole grain of cereals and wheat includes the germ, an area where most of the nutrients accumulate.

Some brands of whole wheat bread are very similar to white

Buying real whole wheat bread is not an easy task. In most supermarket chains, what is sold as whole wheat bread is simply sliced ​​white bread with a minimum of whole wheat flour added.

To make sure it is truly whole wheat bread, whole wheat flour should be listed first on the ingredient list.

Does it have gluten?

It is not news that both white wheat and whole wheat bread have gluten. This is a food that both people who suffer from celiac disease as well as people who carry out a gluten-free diet by choice should avoid.
