It was called Asian rickets, and the flour stayed unfortified

Short answer

Rickets among postcolonial immigrants was framed as an ethnic condition while the population-level fortification that could have prevented it was withheld.

What happened

Bivins traces how postcolonial bodies became research material for vitamin D biochemistry — the Manchester Metabolic Unit from 1963, chapatti-flour fortification pilots — while government declined national flour fortification, citing hypercalcaemia fears and 'cultural' resistance. Medical journals normalised the term 'Asian rickets'. Explanations settled on assimilation and 'dusky skin' rather than on the policy that had eliminated the same condition in the general population decades earlier.

Why it matters

The disease had a known cause and a known population-level remedy already in use. Naming it after an ethnic group relocated the explanation from a withheld policy to the bodies and habits of the people affected — which is a specific, traceable mechanism, not a general observation about racism in medicine.

Limitations
A history of discourse and policy, not an epidemiological estimate. It does not recover every local clinic's practice, and parts of the digitised record are incomplete.

What this connects to

Sources

The one study this explanation is built from, by the role each plays. Every source links to PaperFren’s explanation of it and to the original paper.

Primary study

Before

Rickets was understood as a deficiency disease solved in Britain by wartime and postwar fortification, and its reappearance was read as a problem of the newly arrived rather than of policy coverage.

Now

The research effort and the policy refusal ran side by side, and the naming carried the explanation. This is a history of British medical and policy discourse; it is not a prevalence survey of vitamin D deficiency today, and some digitised colonial-era passages are fragmentary.
