Nutrition
Nutrition
is a
science
that studies the relationship between
diet
and
health.
The purposes of nutrition science is to explain
metabolic and physiological
responses of the body to diet.
Nutritionists are
health
professionals who
specialize in this area of
study, and are trained to provide safe, evidence-based
dietary advice and interventions.
Deficiencies, excesses and imbalances
in diet can produce negative impacts on health, which may
lead to diseases such as
cardiovascular disease,
diabetes,
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.
Many common diseases and their symptoms can often be
prevented or alleviated with better nutrition.
