Refining grain includes mixing, bleaching, and brominating; additionally, folate, thiamin, riboflavin, niacin, and iron are added back in to nutritionally enrich the product. [6] Enriched grains are refined grains that have been fortified with additional nutrients. Whole grains contain more dietary fiber than refined grains.
The conversion of grains to flour involves several steps that vary with the type of grain used. The initial stages of processing remove the bran and the germ of the seed. The bran is the outermost layer of grains that contains fiber (primarily insoluble), some protein, and trace minerals. The germ is the embryo of the seed that contains B ...
Fortification is present in common food items in two different ways: adding back and addition. Flour loses nutritional value due to the way grains are processed; enriched flour has iron, folic acid, niacin, riboflavin, and thiamine added back to it. Conversely, other fortified foods have micronutrients added to them that don't naturally occur ...
Often, refined flour will be the first ingredient (even on “wheat bread”) which is still using refined flour, and therefore, provides fewer of the benefits 100% whole-grains provides—fiber ...
All-purpose, enriched wheat and organic wheat are popular cooking and baking flours, but they’re all refined flour products. So, while tasty, these flours may be associated with certain health ...
Refined grains are stripped of the grain’s germ and bran, which contain fiber and other nutrients. This is why eating refined grains (like white rice) and foods made with them (like white bread ...
"Bleached flour" is "refined" flour with a chemical whitening (bleaching) agent added. "Refined" flour has had the germ and bran, containing much of the nutritional fibre and vitamins, [citation needed] removed and is often referred to as "white flour". Bleached flour is artificially aged using a "bleaching" agent, a "maturing" agent, or both.
In other words, refined grains are not “whole”. For example, white flour and white rice do not have the bran or germ. According to the Whole Grains Council, refining a grain removes about a ...
