A balanced diet should contain all the energy that you
need but not more. The list of what each food group
does is in the notes tab.
Carbohydrates; needed to
release energy.
Protein; used for cell
repair, replacement
and growth
Fats; to keep you
warm and for energy
release
Fibre; to keep the
digestive system flowing
and running smoothly
Vitamins and Minerals; used to
keep everything in general
health
Metabolic rate; is a range of chemical
reactions which take place in the body.
For these to take place they need to be
in an watery environment
energy and a watery
environment is
imperative in order
for these reactions to
be fuelled
There are some variations in the resting
metabolic reaction of some people
Muscle needs more energy than fatty tissue, which means
people with a higher proportion of muscle to fat will have a
higher metabolic rate
Men tend to have a higher
metabolic rate compared
to women
Factors which affect Health
People whom have badly out of
balanced diets are seen or known
as people who are malnourished
Eating too much can lead
to obesity
Excess carbs or fat in the diet
can lead to obesity
Hormonal problems can lead to
obesity, however the usual case is a
bad diet, overeating or lack of exercise
Health problems such as arthritis, type 2
diabetes, high blood pressure and heart
problems can cause obesity
Regular Exercise
People who exercise
regularly are generally
healthier than those who
don't
Exercise increases the amount of energy used by the
body and decreases the amount stored as fat. It also
builds muscle which helps increase metabolic rate
Eating too little can also
cause problems
The effects of malnutrition
vary depending on what foods
are missing from the diet
Deficiency diseases can cause
problems e.g. lack of vitamin C
results in scurvy
Other Health problems...
Too much saturated fat in your
diet can increase blood
cholesterol level
Eating too much salt can
cause high blood pressure
and heart problems
Inherited factors can
affect your health too
Some people can inherit a
good or bad metabolic rate
