A Lesson From the History Books
In the early 20th century, machine processing of food led to the invention of white flour, used to make white bread. After a decade or so of this mass consumption of this food, a vitamin deficiency disease known as rickets became an epidemic across the nation. A congressional inquiry was conducted and it was revealed that this new processed food (white bread/flour) was the source of the problem. Laws were passed and it was mandated that specific B vitamins must be added back into the bread to be legally sold to the public. This is what we know today as enriched white bread.
