Today's program
¬ß 1   Food and nutrients 

Slide 4 - Tekstslide

Learning objectives 
  • You can state the functions of nutrients and dietary fibre in foods.
  • You can name six groups of nutrients and list their functions.

Slide 5 - Tekstslide

Animal or vegetable?
"Food comes from the roots, stems, leaves, fruits and seeds of plants. Many people also eat animals and animal products. Food contains all kinds of nutrients that your body needs."

Foodstuffs = all the products that you eat or drink 
  • Vegetable foodstuffs -> foods that come from plants or made from plants 
  • Animal foodstuffs -> come from animals or animal products (generally bred for this purpose)


Slide 6 - Tekstslide

Butter is an example of animal foodstuffs.
True or False?
A
True
B
False

Slide 7 - Quizvraag

The function of nutrients
"Nutrients are substances that your body needs for energy, growth and recovery."

Nutrients can have four different functions in the body:
  • fuel
  • building material
  • reserves
  • protection

Slide 8 - Tekstslide

The function of nutrients
  • Fuels provide energy. Energy is needed for the body to function.
  • Building materials can help create new or repair damaged tissue(s).
  • Reserves are stored in the body as building materials or fuel that's not needed immediately.
  • Protective substances boost the immune system and make sure you don't get sick.

Slide 9 - Tekstslide

Which one is not a function of nutrients?
A
Fuel
B

C
Building materials
D

Slide 10 - Quizvraag

Six groups of nutrients
  1.  Proteins
  2.  Carbohydrates
  3.  Fats
  4.  Water
  5.  Minerals
  6.  Vitamins 

Slide 11 - Tekstslide

Which of the six groups do you think is most important for the human body?
Proteins
Carbohydrates
Fats
Water
Minerals
Vitamins

Slide 12 - Poll

Proteins
Proteins are building blocks for the body. 
  • cytoplasm
  • muscle

Any excess of protein is used as fuel or converted 
into fats and stored as reserves. 

Slide 13 - Tekstslide

Carbohydrates
Carbohydrates are the primary source of energy. 

  • sugars (glucose)

Glucose can be converted into glycogen
and stored in the liver and muscles. 

Slide 14 - Tekstslide

Fats
Primarily used as fuel. But in excess it's stored as a reserve. 




Name an example of (healthy) fatty foods:

Slide 15 - Tekstslide

Fats

Slide 16 - Tekstslide

Which of the two energy sources is more efficient due to its fast mechanism?
A
Carbohydrates
B
Fats

Slide 17 - Quizvraag

Water
The human body consists of approximately 60% of water. 

  • transporting substances, such as blood, inside your body 

Slide 18 - Tekstslide

Minerals
Minerals are protective substances. Any deficiencies can lead to illnesses.   
Also referred to as 'salts'.

  • calcium -> bone growth, blood clotting
  • sodium -> balance in fluids
  • magnesium -> maintain brain and heart functions
  • iron -> blood production (hemoglobin)

Slide 19 - Tekstslide

Which mineral is good for both bone growth and your blood?
A
Magnesium (Mg)
B
Iron (Fe)
C
Calcium (Ca)
D
Sodium (Na)

Slide 20 - Quizvraag

Vitamins
Vitamins are protective substances. Any deficiencies can lead to illnesses.   

  • Vitamin A -> vision and cell production
  • Vitamin B -> aids the metabolism
  • Vitamin C -> supports the immune system
  • Vitamin D -> mood regulation
  • Vitamin K -> bone metabolism


Tip:
Print out the image to the right. It will be used in the final exam. 

Slide 21 - Tekstslide

Which vitamin supports the immune system?
A
Vitamin A
B
Vitamin B
C
Vitamin C
D
Almost all of them
