New World Syndrome is a set of non-communicable diseases brought on by consumption of junk food and a sedentary lifestyle, especially common to the indigenous peoples of the "New World" (i.e. of the Americas). Indigenous peoples of Oceania and Circumpolar peoples, and perhaps other populations of Asiatic origin are similarly affected and perhaps genetically predisposed. It is characterized by obesity, heart disease, diabetes, hypertension, and shortened life span.
Causes
New World Syndrome is linked to a change from a traditional diet and exercise to a Western diet and a sedentary lifestyle. The traditional occupations of indigenous people—such as fishing, farming, and hunting—tended to involve constant activity, whereas modern office jobs do not. The introduction of modern transportation such as automobiles also decreased physical exertion. Meanwhile, Western foods which are rich in fat, salt, sugar, and refined starches are also imported into countries. The amount of carbohydrates in diets increases.
