The short answer

Use a **swap hierarchy**: overall pattern and ultra-processed food cuts first, then restaurant fry-oil quality, then home heat-matched fats. Single-oil purity contests rank last. See our [seed oils evidence guide](https://healthcanon.com/metabolic-health/seed-oils-evidence-guide).

Linoleic acid is essential; industrial frying abuse and diet pattern quality are different problems than a teaspoon of oil in home cooking.

## How to use this hierarchy

Execute top ranks before boutique grocery swaps. Do not build identity around absolute zero seed oils.
