The researchers analysed the teeth of children and adults from two 19th-century cemeteries, one at a Workhouse in Ireland where famine victims were buried and the other in London, which holds the graves of some of those who fled the famine."We know that stress and poor diet in mothers, both during pregnancy and after birth, can have an impact on a child's development.

"A simple test on teeth that are naturally shed by children as they grow could provide useful information about future health risks," said lead researcher Julia Beaumont from the University of Bradford.Levels of carbon and nitrogen isotopes within bone and teeth, and the relationship between the two, change with different diets. So baby teeth can reveal clues about the diet of the mother during pregnancy and the diet of the child immediately after birth.Nitrogen isotope levels are higher in people on protein-rich diets and in breastfed babies, and lower for vegetarian diets.
