An international team of researchers is studying what types of foods our ancient ancestors ate in Ireland during the Iron Age. Archaeologists are using data and artifacts discovered from commercial digs during the Celtic Tiger years to learn about the dietary habits of people in the southeast of Ireland between 2,700 and 2,000 years ago. Cattle and pigs provided dairy and meat, barley was a staple, and there is also evidence of a variety of wheats, including spelt and emmer.
