Episode notes
Whole Wheat Is A Structural Definition
- Whole wheat means a kernel with endosperm, germ, and bran intact, not a marketing label.
- Milling can remove germ and bran, changing nutritional value and shelf life.

- Roller milling separates bran and germ and extends flour shelf life by removing oils that spoil.

- Many commercial 'whole grain' flours and pastas tested far below expected germ levels.
