23 Aug 2019 --- Adding vitamin D to wheat flour would prevent ten million new cases of vitamin D deficiency in England and Wales over the next 90 years, according to researchers at the University of Birmingham. Their study concludes that fortifying flour with vitamin D alone would save the public £65 million (US$75.4 million) annually by reducing demand for healthcare and treatment for vitamin D deficiency and its complications. Meanwhile, they projected that adding vitamin D to flour would cost just £0.12 (US$0.15) per person per year.
