Module 11

Different types of food for humans

ACTIVITY 1:

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

ACTIVITY 2:

Situation

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.

Specifications

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 the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
