Mining and Dining: Prehistoric Diets in the Salt Mines of Hallstatt

by HEAS Team Leader Kerstin Kowarik

 

The FWF-funded project Mining and Dining investigates the dietary habits of Bronze and Iron Age miners through the analysis of exceptionally well-preserved human excrement recovered from the prehistoric salt mines of Hallstatt, Austria. The aim is to produce high-resolution, individual dietary profiles, offering new insights into nutrition, health, and everyday life in the Metal Ages.

By combining archaeobotanical, parasitological, genetic, and proteomic analyses, the project examines 50 individual palaeofaeces to explore:
• the diversity and complexity of prehistoric miners‘ diets,
• long-term dietary patterns via gut microbiome composition,
• the consumption of fermented and dairy products,
• and possible correlations between diet and biological sex.
This integrated, multi-method approach opens up a new perspective on prehistoric food culture – from cooking and consumption practices to health and social structures – and highlights the unique scientific potential of salt-preserved palaeofaeces.
