Another disease that has become more common in richer countries is diabetes. This is a disease in which the body cannot control the level of sugar in the blood. Diabetes is caused by poor diet and a lack of exercise. We can see from table b that Germany,which is a developed country,has 183.7 deaths per million people. On the other hand,in Peru,a developing country,the death rate is just 61.3 per million people. The rate in Germany is more than three times the rate in Peru.
