I believe that it has to do more with diet in the U.S. Our country has become one of a huge population of the over weight and in poor health, due to eating the wrong foods necessary to maintain a healthy body. A big ingestion of beef and other protein that has been chemically treated to promote growth by the various industries and fried foods account for many health problems in this country. Over use of sugar and white bread in the diet also has been found to be at the root of many problems such as diabetes, cardiovascular disease and these accompanied by exposure to poor environmental conditions such as pollution, in the water and air, all help make for troubling health conditions. Many of the once healthy sea foods that were abundant in the country has been subjected to polluted conditions over many years and greatly affects quality in the foods that we eat. More attention has also been given to people who were once regarded as growing older, and now the specific problems that they have are more under investigation.
