High cost of healthy food linked to stunting, new study finds (Devex)

July 23, 2019


Devex reported on a new study by Senior Researchers Derek Headey and Harold Alderman on the relative caloric prices of healthy and unhealthy foods across income levels and continents. The article described the study’s key takeaway and quoted Derek Headey, who emphasized that poor people in developing countries not only have poor income, but live in poor food systems where nutritious foods are expensive. Headey noted that more research is needed into making nutrient-dense foods more widely available in poor countries.
