Fats & Oils Tier List

The most argued-about board. We credit unsaturated fats (MUFA plus PUFA), punish saturated fat, and reward foods that kept their micronutrients. Butter does not enjoy this rubric.

How the grading works: scored per 100 calories on fixed benchmarks, weighted, ranked. Read the full methodology — the formula is published, argue with it.
