The Immune Priming
An immune system tuned to a hair trigger.
The idea
Chronic metabolic inflammation does not just damage tissue, it retrains the immune system. A system built for infection and famine ends up chronically activated against metabolic signals instead, responding to ordinary stimuli with outsized inflammation. The mechanism is universal; the earlier metabolic strain in South Asian bodies simply pulls the trigger sooner. Whether this priming is acquired early in life, and therefore preventable, is one of the framework's open questions, not one of its settled claims.

How the evidence grades it
Every study is labeled by what it does to this concept. Counting the counterevidence is the point.
