Bone Diet

Another type of disease observed are those that reflect the diet an individual had during their life. Poor diets can lead to many health problems and illnesses, and the types of food eaten may also cause changes in the bones. A lack of nutrients such as vitamin C and D in the diet may lead to metabolic disorders, such as scurvy and rickets. These can affect growth and prevent the development of strong and healthy bones. Diets too rich in certain foods may also lead to illness.
One such diseases is gout, this results from a build up of uric acid in the body and may be associated with a high alcohol intake and diet rich in protein and fatty foods (Roberts and Manchester 2005). Crystals of uric acid may form in the joints and lead to inflammation. This can affect the joints of most limbs but is most commonly observed in the first metatarsophalangeal joint (big toe), causing joint pain and stiffness. Over a period of time this swelling may lead to erosion of the bone at the joint. This can be seen in skeletal remains as punched out lesions with overhanging edges (Rogers and Waldron 1995). Six adult individuals (6/268: 2.2%) from the Catholic mission of Saints Mary and Michael, Whitechapel, London, displayed evidence of gout. All had erosive lesions of the big toe.
Another disease that may be related to a rich diet and obesity is Diffuse idiopathic hyperostosis or DISH. This is caused by the ossification (turning to bone) of ligaments in the spine and other sites of the body such as areas of tendon and muscle attachments. This can result in individual vertebrae of the spine becoming fused together, with the new bone having the appearence of dripping candle wax (Rogers and Waldron 1995). Two males, both aged over 46 years at death were diagnosed with DISH in the Saints Mary and Michael cemetery population. Both showed the typical fusion of over four continuous vertebrae.
The occurrence of these diseases, when compared to an entire cemetery population, can help us to learn about and understand the health and lifestyle of people in the past. They may help reveal the types of diets eaten, the foods available, and make inferences about a populations background and status.
