> that changed with agriculture some 480 generations ago; enrichment is merely the solution

Whoops, typo—I meant nutritionally deficient.

Hunter-gatherers had a varied but volatile diet. Agriculture solved the volatility at the expense of variety. Most agricultural humans across history were nutritionally deficient.

Enrichment (a/k/a fortification) started to solve for the lack of variety, though it’s been historically stymied by our lack of understanding what e.g. vitamins are; modern farming, biology and logistics enable us to actually solve for the problems agriculture introduced to society for the first time.
