Chapter 6 Summary
- Health lies in the medical domain, however,
health is affected by physical activity and nutrition, both
of which have a key role to play in primary prevention and
in secondary care management.
- Health is a wide ranging concept, as evidenced

attempt to guide the population to better health.
- Dimensions of health might include physiological
health, the absence of disease, the freedom from illness
and psycho-social health.
- The population approach to improving health
complements the high risk approach, the latter having the
potential to be influenced by nutrigenomics – the
influence of nutrition and individual genetic variation
on risk factors for chronic diseases.
- A major risk of physical inactivity is
the incidence of coronary heart disease, the risk amongst
sedentary people being nearly two-fold.
- There are numerous benefits to health
of regular physical activity, including those that benefit
the cardiovascular and musculoskeletal systems, and metabolism,
and psychological health.
- Measurements of population physical activity
levels have shown that in affluent countries such as the
U.K., the majority of the population are insufficiently
active to optimally benefit health.
- Nutrition, working in tandem with physical
activity can remodel physiology and metabolism and improve
- Disease risk, in states such as diabetes
mellitus and cancer can be reduced through optimal nutrition,
and can also be used to manage aspects of disease.
- Alcohol has found a place in society
and in culture but can be detrimental to both short-term
and long-term health, contributing significantly but unhelpfully
to energy intake, and also to hypertension
