Sources of nutrients 11/01/2015 • State sources and uses of nutrients in the body • State some essential nutrients and deficiency symptoms

Sources of nutrients 11/01/2015 • 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.

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.

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

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

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

Selective breeding

Most common causes of shortage: War, economics, poverty War • 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.
