In general, the development of civilization is viewed as a positive step for the well-being of the human species, leading to an increased duration and quality of life. The accelerated progress of civilization (mainly industrialization, urbanization and nutrition) has lead to new possibilities for adverse effects on human health. In former high civilization--like old Egypt, Greece, Roman, Chinese, Indian, Maya civilizations--the "modem civilization diseases" were unknown. Modem science through improved sanitation, vaccination and antibiotics as well as improved social and economical conditions, has eliminated the threat of death from most infectious diseases. In the years after World War II the social, economic and health conditions changed. Most deaths have resulted from heart disease, stroke, cancer and other diseases as a result of an inappropriate relationship of people with their environment and changed lifestyle. Lifestyle diseases are different from other diseases because they are potentially preventable and can be lowered with changes in diet, lifestyle and environment.
