Diet
- Balanced diet
- diet must provide enough
energy
- Enough carbohydrates to release
energy
- Enough fats to keep warm and
release energy
- protein for growth, cell repair
and replacement
- fibre for everything to move smoothly
through your digestive system
- tiny amounts of vitamins
and mineral ions to keep
skin, bone and blood
healthy
- Energy needed to fuel
chemical reactions in body
- Metabollic rate
- higher proportion of muscle
= higher metabollic rate
- the bigger you are the more
energy needed to supply your
body so higher metabollic rate
- excercise boosts
metabollic rate as muscle
is built up
- stays high for a while after
excercise
- activity levels affect how much
energy should be in your diet
- Unbalanced diet
- excess carbohydrates and fat = obesity
- obesity can lead to arthritis, type 2 diabetes,
high blood pressure, heart disease and some
types of cancer
- excessive
saturated fat can
increase blood
cholesterol level
- excessive salt can increase blood cholesterol level
- people in developing countries suffer malnutrition
- malnutrition varies depending on what
foods are missing from the diet
- malnutrition can lead to slow growth,
fatigue, poor resistance to infection &
irregular periods
- difficiency diseases are caused by lack of vitamins or minerals, eg.
vitamin c - scurvy problems with skin joints and gums
- Exercise and inherited facters
- excercise increases amount of energy used and
decreases amount of stored of fat
- less likely to suffer from
diseases like obesity
- and underactive thyroid gland can cause a slow in the
metabollic rate and cause obesity
- some inherited factors increase blood
cholesterol levels which increases risk of heart
disease
