Module 11

Different types of food for humans


To be able to discuss the value of different types of food for humans.

  • Food performs three functions in our bodies, namely:

a) it serves as building blocks

b) it provides energy

c) it provides protection

  • It is important for us to eat correctly. Alcohol and sugar, e.g. sweets, cakes, jam and cold drink are not beneficial to the body.
  • The table on the next page indicates the food groups, nutrients and number of portions required daily to ensure a healthy diet.

1. Collect pictures of the five food groups and paste them in a folder. Then write down the main nutrient and the function of that nutrient in each group.

  • Food Group
  • Examples
  • Main Nutrient
  • Function of Main Nutrient

2. Now formulate six dietary objectives for yourself, with reference to the information.

LO 1.2 LO 1.3



A unique opportunity has arisen for all small businesses interested in erecting a stall at the coming World Fast Food Fair. Every stall will be expected to produce tasty fast food representing a specific country. Your educator will divide you into groups and give you the opportunity to draw the name of a specific country to represent.


Each stallholder will be expected to produce the fast-food meal in front of a panel of judges. The panel will look at the following points:

  • The fast food meal and stall must represent the chosen country.
  • The food must have a high nutritional value.
  • The food must be produced by means of a production line system (as in bulk).
  • The food must be packaged attractively.
  • Health and safety rules must be observed.
  • Preparation time may not be more than eight minutes.

1. Work in groups of two or three and make preparations to form a company, think up a name and design a logo for the company.

2. Compare the staple food and fast foods of two countries/cultures.

LO 3.1

3. Research

Now do in-depth research on the food of your specific country, on fast foods in general and on health and safety in fast-food outlets.

LO 1.1 LO 1.4

4. Ideas

Use the information you collected during your research and generate three ideas for your fast food meal. Bear the following in mind:

  • The availability of ingredients
  • Presentation - packaging of the end-product
  • Production process
  • Preparation time
  • Each idea must contain the name, a drawing and a description of the fast food.
  • Now choose a final idea and make an attractive colour drawing of your product.
LO 1.7 LO 2.2

5. Planning

Do the following planning (first in rough) and write only your final effort:

  • List of utensils
  • Shopping list
  • Costing of ingredients
  • Selling price of product

6. Fast food production system

You are going to produce your fast food meals by means of a production line. The production line must be planned in such a way that all members of the group participate actively, make maximum use of time and are organised so that every step of the production line is effective.

In a production line all steps are equally important. The production line must be well planned so that the entire process runs smoothly and is effective.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
