food fortification

In Cambodia and other parts of Southeast Asia, infantile beriberi is a public health concern. If not arrested it can be fatal. If a pregnant woman consumes a diet deficient in thiamine, her breast milk will not supply enough to her baby to prevent beriberi. A possible means of ameliorating this situation is to fortify a commonly-consumed food with thiamine.
Catherine Price asserts that it is the enrichment or fortification of processed foods with synthetic vitamins that allows (maybe even causes?) us to consume unhealthful diets
