White bread

Template:Short description Template:About Template:Infobox food White bread typically refers to breads made from wheat flour from which the bran and the germ layers have been removed from the whole wheatberry as part of the flour grinding or milling process, producing a light-colored flour.<ref>Template:Cite book</ref>

Nutrition

{{ safesubst:#invoke:Unsubst||date=__DATE__ |$B= Template:Ambox }} White bread contains half of the magnesium found in whole-wheat bread, and it is generally considered to be less nutritionally dense.

The milling process can give white flour a longer shelf life by removing the natural oils from the whole grain. Removing the oil allows products made with the flour, like white bread, to be stored for longer periods of time avoiding potential rancidity.

History

File:Slab stele from tomb of Itjer at Giza 4th Dynasty c 2500 BC.jpg

Ancient Egyptian aristocracy had access to white bread. In this image bread is depicted in Egypt in about 2,500 BC.

Bread made with grass grains goes back to the pre-agriculture Natufi proto-civilization 12,000 years ago.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> But only wheat can feasibly be sifted to produce pure white starch, a technique that goes back to at least ancient Egypt.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Because wheat was the most expensive grain to grow, and the process to sift it labor-intensive, white flour was generally limited to special occasions and the wealthy, until the mid-19th century. Then industrial processes eliminated the labor cost, allowing prices to fall until it was accessible to the middle class.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In the US, corn meal was the standard grain for bread until closing in on the 20th century, while in Europe it was other grains.

But once accessible, white bread became very popular in industrialized countries for a number of reasons:

• It was easier to see as pure and clean, at a time when some foods could be poorly made and adulterated.
• The lack of both coarseness and complex flavor profile made it a popular medium for the delivery of flavorful condiments.
• It is more easily chewed and digested. This allows it to be a source of more calories. It also does make some micronutrients more digestible, some studies finding that the added nutrition in whole grains tends to pass through the body unabsorbed.<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref> For some body types and diets, white flour may have been a nutritional benefit.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

• Once it could be easily produced, it went from the most expensive to among the cheapest kinds of flour.
• It can last longer. The wheat oil in whole grain breads can go rancid over time, spoiling its flavor.

However, there was a backlash from the popularity of white flour, giving rise to whole grain alternatives popular to this day, such as graham crackers and corn flakes, which (in their original whole grain form) have more fiber and micronutrients. Eventually, the transformation of white bread from an elite to a common foodstuff became symbolic of the success of industrialization and capitalism in general, especially paired with the advent of machine sliced bread in the 1920s.Template:Cn

Homemade white bread

In the United States, consumers sometimes refer to white bread as "sandwich bread" or "sandwich loaf".<ref name="Mercuri 2009 p. 9" /> It is often perceived as an unhealthy, bland, and unsophisticated menu item.<ref name="Rise and fall">Template:Cite news</ref><ref>Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Japanese milk bread, a type of soft white bread, is popular in Asia, particularly in Japan, and has artisan status there.<ref name=":0">Template:Cite news</ref><ref name=":1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Bread was not a traditional food in Japan, but it came into culinary use there after the American response to post-World War II Japanese rice shortages included relief shipments of wheat.<ref>Template:Cite news</ref> The style of bread became popular outside Asia in the 2020s.<ref name=":2">Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Fortification

While a bran- and wheatgerm-discarding milling process can help improve white flour's shelf life, it does remove nutrients like some dietary fiber, iron, B vitamins, micronutrients<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and essential fatty acids. The US government has mandated since 1941 fortification of white flour-based foods with some of the nutrients lost in milling, like thiamin, riboflavin, niacin, and iron. This mandate came about in response to the vast nutrient deficiencies seen in US military recruits at the start of World War II.<ref>Template:Cite journal</ref> This fortification led to nearly universal eradication of deficiency diseases in the US, such as pellagra and beriberi (deficiencies of niacin and thiamine, respectively) and white bread continues to contain these added vitamins to this day.<ref>Template:Cite journal</ref>

Folic acid is another nutrient that some governments have mandated is added to enriched grains like white bread. In the US and Canada, these grains have been fortified with mandatory levels of folic acid since 1998 because of its important role in preventing birth defects. Since fortification began, the rate of neural tube defects has decreased by approximately one-third in the US.<ref>Williams, L.J., et al.
