CHAPTER 4. Names and Sources of Food

UNIT 9 FOOD AND NUTRITION
P1 TERM 3

Objectives

By the end of this unit, pupils should be able to:

1. Describe why we need food.
2. Name the foods we eat.
3. Name places from where food is obtained.
4. Name ways of collecting foods.
5. Name ways of how food gets dirty
6. Mention ways of keeping food clean.
7. Name and demonstrate good eating habits.

Behavioural Changes

Pupils should:

· Eat good food at regular times.
· Collect different foods from various places.
· Wash hands before touching food.

Main Ideas

· Different types of food help our bodies in different ways.

· Some foods make our bodies grow bigger. These are body-building foods or grow foods.

· Some foods give us energy to play, walk and do manual work.

· Other foods protect our bodies from getting certain diseases and help the bodies work properly. These are called protective foods.

· Foods are obtained from farms, gardens, markets, shops, rivers etc. Foods may be wild plants or insects.

· Foods get contaminated by dirty hands, flies, dirty containers etc.

· Hands should always be washed before eating or handling food.

Notes for the Teacher

Food is any substance which when taken into the body will nourish the cells and enable the body to grow, do work, carry out other activities, and keep the body healthy.

The substances in foods which help with all body processes are found in different forms and quantities in different foods. As a result, some foods make the body grow bigger, others provide energy and others repair damage and protect us from disease.

Body-Building/Grow Foods:

These are eggs, milk, fish, meat, soya beans, peas, ground nuts, edible insects, yoghurt, liver and kidneys.

Energy-Giving/Go Foods:

These are cooking oil, butter, margarine, jam, sugar, maize, bananas, potatoes, rice, cassava, yams, bread, cakes, sweets.

Protective/Grow Foods:

These are fruits, vegetables, salt, water, butter, margarine and eggs. Children need a lot of body building/grow foods in order to increase in height and weight, that is to grow up. Children and other people also need energy giving foods. These foods help them to walk, play, keep alert and warm.

Protective grow foods keep our eyes, skin and hair shining. These foods also protect us from getting diseases like night blindness, rough skin and help to purify our blood. They also enable us to fight against other diseases.

It is recommended to eat at least one food from each group everyday. This makes up a balanced diet.

Foods are obtained from

a) farms and gardens e.g. matooke, potatoes, millet ground nuts, maize pawpaws, green vegetables etc.

b) lakes and rivers e.g. fish, crab, lobsters etc.


Figure
c) animals e.g. meat, milk, liver, kidney, pork, mutton


Figure
d) birds e.g. chickens, ducks, pigeons, doves, eggs, turkey


Figure
e) Some edible insects: e.g. grasshoppers, ants,


Figure
f) some wild fruits we can eat: e.g. straw berries, "matunguru" N "ocao" "ntuntunu", "Apedur" (Tammarin)

People who live by farming eat fresh foods which are very good.

But people who live in towns and cities have to buy their foods from the markets, shops or super markets. Foods bought in shops, markets, and super markets are more expensive and not as fresh as foods obtained from the farm or garden.


Figure

There are many ways of collecting foods to eat. e.g. fishing, harvesting, buying from shops or markets, milking, sucking from mother's breasts etc.

Dirty Foods:

Foods are made dirty by dirty hands, flies, dirty containers, dust which settles on uncovered foods or soil which may be on the food. Dirty foods make us sick. When fruits fall on the ground from a tree, they become dirty with dust and soil. Sometimes a fruit like mango may fall on faeces on the ground. Then it becomes dangerous to eat that fruit before washing it thoroughly.

Dirty hands can also spread disease. When we go to the latrine/toilet or touch dirty objects, we often contaminate our lands with germs which may be carrying disease. That is why we should always wash hands before eating, and after visiting the latrine or toilet.

Good Eating Habits

a) Wash hands before eating, and after visiting the latrine/toilet.

b) Chew food properly and eat slowly, not hurriedly. Then much of the food will be useful to the body.

c) Do not talk with your mouth full of food; you may choke.

d) Eat food from each food group - eat a balanced meal.

e) Have regular meals. Eat enough from each group.

f) Wash hands after eating food.

g) Never eat left over smelly food. It may be poisonous.

h) Wash fruits and vegetables before eating them.

i) Do not eat food that has dropped on the floor. It may have picked up germs.

j) Eat well cooked foods. Brush teeth after eating food.

All Effects of Bad Eating Habits:

Bad eating habits can endanger our health:

1. Constipation is one of the will effects of bad eating habits.

· improper chewing delays digestion thus causing constipation.

· Other common causes of constipation are eating at short intervals and eating too much food.

2. Another danger is eating too little food.

This may come about if one generally swallows food too fast. It is heaped in the gullet and one feels that he has had enough food.

3. Drinking too much liquid when one is eating prevents a person from eating enough solid food. Too much liquid (e.g. water) may also dilute digestive juices and interfere with digestion.

4. Talking or laughing too much may cause food to go into the wind pipe and obstruct the respiratory system, or one may unknowingly swallow a dangerous solid e.g. a bone.

SOME ACTIVITIES FOR PUPILS:

a) Play a blindfold game to identify various types of food by taste, smell, and touch.
b) Visit market near school, and find out where the food comes from.
c) Help in the school farm and home garden.
d) Make a food corner - market with food wrappers and containers.
