Why we cite it
Popularizes a framework of "four pillars" common to traditional diets worldwide and argues that industrial food processing — particularly seed oils — drives chronic disease. Provides a perspective on traditional cooking fats and whole-food preparation that supports the project's cooking oil and whole-food discussions. Note: several claims (seed oil toxicity, epigenetic determinism, facial symmetry) are contested by mainstream nutrition science; the project uses this source for its less controversial elements (traditional food preparation, cooking fat quality) rather than as sole authority.
