Abstract

It is interesting to know that the human population has reached from one billion to today’s level (approximately 7.6 billion) in only last two centuries. Since the vital point should be not the huge numbers but the quality of lifespan, the success of humanity will come from both healthy socio-economic status and physico-mental wellness. Similarly, WHO (World Health Organization) defines the health as the state of complete physical, mental and social wellbeing and not merely the absence of disease or infirmity. Since the prevention and the treatment of the diseases is the first case for the medical point of view, to find out the possible reasons is crucial. According to global health risks [1], high blood pressure, tobacco use, high blood glucose, physical inactivity and overweight and obesity (13%, 9%, 6%, 6% and 5%, respectively) lead to the mortality in the world in 2004, in addition to the increase in the risk of chronic disease such as heart disease, diabets and cancers.
