PPENZA:Scientists in England may have found a new way to predict the specific health risks children will face when they grow up — and it involves simply looking at their baby teeth.
The idea came from a new analysis of the teeth of victims of the Irish Potato Famine conducted by archaeologists at The Universities of Bradford and Durham.
Old teeth, new analysis. The researchers analyzed baby teeth unearthed from 19th-Century cemeteries in Ireland — where victims of the famine were buried — and in London, where many families who fled the famine settled. They looked at levels of nitrogen and carbon in the teeth, and found that the teeth of people who died in infancy had higher nitrogen levels than the teeth of people who lived into childhood or adolescence, The Guardian reported.
The finding seems to challenge the notion that high nitrogen levels are an indicator of good nourishment in infants, since nitrogen isotope levels tend to be higher in breastfed babies.
