There are at least three types of health education. The first and most common is education about the body and how to look after it. The provision of information and advice on human biology and hygiene is vital for each new generation. The second is about health services-information about available services and the "sensible" use of health care resources. But the third, about the wider environment within which health choices are made, is relatively neglected. It is concerned with education about national, regional, and local policies, which are too often devised and implemented without taking account of their consequences for health. This third type is part of the currently moribund public health tradition. At a time when many are trying to improve methods of health education at least equal attention should be paid to its content.
