Why do Americans have such an unhealthy diet?
What we’ve known for a long time is that the major determinates of the most important diseases in this country, such as most cancers, cardiovascular disease, stroke and diabetes, are not genetic factors, but diet and lifestyle factors. We’ve known it for many years because we’ve learned that people in other countries, say Africa and parts of Asia and Latin America, often have extremely low rates of the diseases that are major causes of death in this country. When these people migrate to the United States, they get virtually the same rates that most people in this country are experiencing.
