Hidden in a slightly industrial-looking strip mall in the middle of Pasadena, California, is a flour mill. It's called Grist & Toll, and Nan Kohler is the owner and miller.

After showing us around the facility, Kohler explained why our culture traded in whole wheat flour for the white, highly processed stuff we see on the grocery shelves today.
Nan Kohler: As long as there's been wheat, and milling, and baking, there's been a desire to have white refined flour. White flour, white bread, has symbolized so much in our history: class, wealth, status, politics, religion. We are very tied to white bread and white refined flour.
