A chemical analysis of the teeth and bones of King Richard III reveals that his diet was decadent even by standards of medieval royalty.

During his two-year reign, 1483 to ’85, Richard III feasted on expensive freshwater fish and such exotic birds as swan, crane and heron, the study said. And he was consuming vast quantities of wine.

To see how the king’s diet evolved, researchers from the British Geological Survey and the University of Leicester analyzed the chemical isotopes in two teeth, one rib and a femur from his remains, which were discovered under a parking lot in Leicester in 2012. The teeth, which form at childhood, provided evidence of his early diet; the femur, which regenerates slowly throughout one’s life, offered an average of his last 10 to 15 years; and the fast-regenerating rib told of his last two to three years before his death in battle.

By analyzing the carbon, nitrogen and oxygen isotopes in each bone, the researchers, who reported their findings in the Journal of Archaeological Science, were able to deduce what he ate, how much he drank and even where he lived at various times.
