The food an animal eat everyday is called diet. Most animals need 7 types of nutrients in their diet: 
Carbohydrates
Proteins
Fats
water
fibre,
vitamins,
minerals.

5. The amount of energy needed is provided mainly by our carbohydrate and fat intake. Your dietary requirements depend on your age, sex and activity.
Age: The energy demand increases
until we stop growing.
While children are growing they
need more protein per kilogram of
body weight than adults do.
Sex: Generally, males use up
more energy than females.
Pregnant women need
extra nutrients for the development of the fetus. 

6. Malnutrition is the result of not eating a balanced diet.
A balanced diet is a diet that contains all the main nutrients in the correct amounts and proportions to maintain good health.
Malnutrition is the result of not eating a balanced diet. 
There may be:
1. wrong amount of food: too little or too much 
2. incorrect proportion of main nutrients 
3. lacking in one or more key nutrients 

7. Causes (pg 74)
Prevention? (pg 74)
How do we identify Obesity ?

8. Cholesterol is a chemical made in the liver and found in blood
Essential: To make bile salts, vit D, cell membranes and hormones.

10. PEM Protein energy malnutrition
See page 76
PEM Protein energy malnutrition
Traditional crops sweet potatoes and cassava fulfill energy requirements but are low in protein
Wheat and rice contain more protein

16. Selective breeding

19. Most common causes of shortage: War, economics, poverty
reduce people available to farm the land,
No go zones
Destroy land
Grow and sell non-food cash crops to gain foreign currency/arms
No safe to transport food from supply to demand.
Economics/poverty
Sell food
Non-food cash crops to gain foreign currency
Cant afford to buy food if it is available
Increasing population: population may grow so large that the land on which they live can no longer provide enough food for them
Climate change and natural disaster such as drought and flooding, pests, diseases that  prevent crops from growing
Famine usually failure to transport food to those in need., political pressure/war.
