"You are what you eat" is a saying. Diet and environment affect our bodies and are reflected in our health. This is true today and it also applies to the people who lived in southern Sweden 4 000 years ago. Therefore, the skeletal material from the people who lived in the past can also provide information about the life that was lived then. During the last part of the South Scandinavian Stone Age, the Late Neolithic, and the first part of the Bronze Age (c. 2300-1100 BC), major social changes took place that resulted in a more hierarchical society. One of the reasons for this is the so-called secondary product revolution. This means shifting the economic focus from using the primary products of livestock, i.e. meat, to using the secondary products, i.e. milk, wool and labor. The economy becomes broader, creating an economic surplus and engaging in trade. This opens the door to a power elite with greater resources than others. Such major societal changes also have consequences for human diet and health. By examining the skeletons, I study people's height, diseases/injuries and demographics to determine whether health has changed during this time. In addition, by conducting biochemical analyses, I study the diet of people during this period and whether the diet was the same for everyone. The results can provide a deeper understanding of the changes that led to the society we have today.
