The Rich get... fatter?

We've all heard the saying that "The rich get richer and the poor get poorer," and we once believed that only rich countries need worry about the troubles of chronic disease. Unfortunately, the troubles of chronic disease have spread across the board from the rich and the poor living in developed countries all the way to those living in developing countries. In my opinion this shift toward chronic disease in developing and poor countries may be just what the doctor didn't order. The rise in chronic disease, in most situations, is a result of the increasing ease of relying on unhealthy foods that are high in fat and sugar and also lack essential nutrients to maintaining a healthy lifestyle. In regards to countries like the United States we are fortunate to have the medical care and health preventive programs in place that we do. By having these resources chronic disease can be treated and even cured so that we may live alongside chronic disease without sacrificing quality of life. On the other hand, poor and developing countries haven't been so fortunate. Without the medical care and preventive programs in place that we have they live in a world sticken with chronic disease. This lack of resources leads to millions of deaths worldwide each year, without mention to the millions left mentally and physically disabled by their chronic disease for the remainder of their life. So now the question isn't "Why do only the rich suffer from chronic diseases" but rather "Why do the poor and developing country peoples suffer so much more from chronic disease and how can we stop chronic disease rates from increasing worldwide?"
