What This Does Not Prove
Celiac disease does not prove that bread is bad for everyone.
It does not prove the refined-carbohydrate hypothesis. It does not prove Taubes right, Yudkin right, or the Food Pyramid wrong.
It proves something narrower and still important.
For some bodies, wheat is medically dangerous. For Catholic sacramental law, wheat remains materially required for eucharistic bread.
That collision exposes the hidden strength of the symbol.
When a secular food trend rejects gluten, the tradition can ignore it. When diagnosed celiac disease meets valid matter, the problem becomes harder to wave away.
The chapter therefore belongs after Cleave Yudkin Jenkins Taubes but before The Architecture of the Invisible. It shows that bread’s authority persists not only in language and policy, but in the rules of a living sacrament.
The lesson is precision, not panic.
