If
you've got a big gut and you start doing sit-ups, you are going
to get bigger because you build up the muscle. You've got to get
rid of that fat! How do you get rid of fat? By changing your
diet. ~ Jack LaLanne
Health
is the functional and/or metabolic efficiency of an organism, at
any moment in time, at both the cellular and global levels. In
any organism, health is the ability to efficiently respond to
challenges (stressors) and effectively restore and sustain a
"state of balance," known as homeostasis. Sickness is
merely the absence of health. All organisms, from the simplest to
the most complex, reside on a spectrum between 100% health and 0%
health.
Nutrition
is a science which studies the relationship between diet and
states of health and disease. Dieticians are Health professionals
who are specialized in this area of expertise. They are also the
only highly trained health professionals able to provide safe,
evidence-based and accurate dietary advice and interventions.
Between
the extremes of optimal health and death from starvation or
malnutrition, there is an array of disease states that can be
caused or alleviated by changes in diet. Deficiencies, excesses
and imbalances in diet can produce negative impacts on health,
which may lead to diseases such as scurvy, obesity or
osteoporosis, as well as psychological and behavioral problems.
Moreover, excessive ingestion of elements that have no apparent
role in health, (e.g. lead, mercury, PCBs, dioxins), may incur
toxic and potentially lethal effects, depending on the dose. The
science of nutrition attempts to understand how and why specific
dietary aspects influence health.
Physical
exercise is the performance of some activity in order to develop
or maintain physical fitness and overall health. It is often
directed toward also honing athletic ability or skill. Frequent
and regular physical exercise is an important component in the
prevention of some of the diseases of affluence such as cancer,
heart disease, cardiovascular disease, Type 2 diabetes and
obesity.
