Biology 1A- Unit 1 core: Diet and
Health
- 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
- Carbohydrates; needed to
release energy.
- 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
- 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
- energy and a watery
environment is
imperative in order
for these reactions to
be fuelled
- 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
- People who exercise
regularly are generally
healthier than those who
don't
- Excess carbs or fat in the diet
can lead to obesity
- 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
- The effects of malnutrition
vary depending on what foods
are missing from the diet
- 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
- Too much saturated fat in your
diet can increase blood
cholesterol level
- Inherited factors can
affect your health too
- Some people can inherit a
good or bad metabolic rate
- Affect values of blood
cholesterol levels
- Some people can inherit a
good or bad metabolic rate
- People whom have badly out of
balanced diets are seen or known
as people who are malnourished
