Bones from a Bronze Age settlement in a low-lying area in The Netherlands were analysed for their content of strontium and certain other elements. Low strontium concentrations in the human bones indicate that part of the diet consisted of animal products. Milk and dairy products were probably also incorporated in the diet. This would have had a marked effect on the Sr/Ca ratio of the total diet and on the strontium content of human bones. Anomalous mean strontium concentrations for the animal species are tentatively explained in relation to the specific environment of the settlement. Different pasturing practices for cattle and sheep/goat respectively are possibly reflected by the strontium content of their bones.
