Diet analysis was carried out of the burial site of the Gerulata II military-civilian station on the Limes Romanus on the Danube River and of the Germanic burial sites in Abrahám and Sládkovico. All skeletal sets were dated to the 1st-2nd centuries AD. 15 chemical elements were determined. The zinc, strontium and lead content of the skeletal materials was the basis for the reconstruction. The population of the Sládkovico site used a diet based on sources with a high zinc content, probably in the form of meat and milk, while in Abrahám foodstuffs a relatively high strontium content predominated, i.e., diet of prevailingly vegetable origin. Strontium sources used in Gerulata II were more similar to Sládkovico than to those in Abrahám. In Gerulata II it has been established that the concentration of zinc, strontium, and lead in the proximal parts of the femur in the age groups up to 20 years was age related. In the 0-2 year and 10-15 year age brackets the concentration was rising, while in the 2-10 year and 15-20 year groups the concentration of the elements was falling. -- AATA
