However, providing information is not enough. People's health-related lifestyles in any community are closely related to the general lifestyles of the community and to the general beliefs, norms and social values. Thus, it is often difficult for the individual to make major changes in lifestyle, if respective changes do not take place in the community and, more generally, in society as a whole. Therefore, successful large-scale preventive programmes attempt to change, not so much the individuals, but the whole community and many of its social and environmental factors. This involves decisions and actions that make healthy choices possible and easy.
