Different geography, different ingredients, the same underlying logic showing up again and again.
Traditional dietary patterns from very different parts of the world — developed independently, over centuries, for entirely different reasons — converge on strikingly similar underlying principles.
Olive oil, fish, legumes, vegetables — see our dedicated comparison.
Soy, seaweed, fish, and a wide variety of vegetables, historically eaten in smaller portions with less processed food.
Rye, oats, berries and cold-water fish — see our dedicated comparison.
Legume-heavy dals, a wide range of vegetables, and turmeric and other spices used daily rather than occasionally.
Whole grains or legumes as a staple, fish or plant protein over heavily processed meat, generous vegetables, and traditional preparation methods over industrial processing — different ingredients shaped by geography, but a strikingly similar underlying logic.
This convergence is a big part of why THE FAD's Food signal isn't tied to any single named diet — the same underlying principles show up, independently, across very different food cultures.
