*Published 2026-07-10 · By Marcus Chen*

*Disclaimer:* Nutrition evidence map—not a personalized medical diet.

The short answer

Map claims to **evidence layers**: essential fats and overall pattern first; be skeptical of absolute seed-oil demonization and of unlimited fried UPF. See [seed oils guide](https://healthcanon.com/nutrition/seed-oils-evidence-guide) and [swap hierarchy](https://healthcanon.com/nutrition/best-seed-oil-swap-hierarchy-2026).

Internet binary wars erase cooking context and food matrix.
