Slide 6 - Diapositive

learning objective
  • You can name the functions of nutrients in foods.
  • You know 6 groups of nutrients with their functions.

Slide 7 - Diapositive

Nutrients: usable components in food
Dietary fibre: are indigestible parts of the plants 
vegetable products
Animal products
Foodstuffs

Slide 8 - Diapositive

Function of Nutrients
  • Building material: grow/develop/repair
  • Fuels: by combustion in cells to provide energy
  • Reserves: to store up
  • protection: to stay healty  

Slide 9 - Diapositive

6 groups of nutrients.

carbohydrates
fats
proteins
minerals
vitamins
Water

Slide 10 - Diapositive

Carbohydrates
  • includes: glucose, sugars, starch, glycogen
  • primary used as fuel
  • also: building material and reserves
  • glucose high: converted into glycogen                                                                           and stored in liver and muscles.
  • glucose drops: glycogeen converted into  glucose and released into the bloodstream

Slide 11 - Diapositive

fats
  • primarily used as fuel 
  • also as buildingblock or reserves
  • reserves are stored beneath your skin
  • the subcutaneous fatlayer becomes                                                     thicker.
  • we mostly eat more fat than we need

Slide 12 - Diapositive

Proteins
  • Important buildingblocks
  • also: fuel
  • Which foodstuffs contain proteins?
  • beans, yoghurt, cheese, eggs, red meat, chicken, fish, tofu 

Slide 13 - Diapositive

Water
  • Building material!
  • Your body is made up of 60% water
  • has a key role in transporting substances around your body
  • most substances can be only transported properly if they are dissolved  

Slide 14 - Diapositive

Minerals (or salts)
- Buildingblocks. Like calcium for strong bones
- also protective substances

Slide 15 - Diapositive

Vitamins
  • building material and protection
  • prevent illness
  • (but consuming large quantities can be harmful)
-A: producing skin and seeing well
-B12: Red bloodcells
-C: defense / immunity
-D: Strong bones

Slide 16 - Diapositive

(dietary) fibre
- Fibres belong to carbohydrates.
- We CANNOT DIGEST them and therefore 
   excrete them.
- FUNCTION:
  + Ensure good bowel function,
  + Give a feeling of fullness (feeling that you're full),
  + Reduce the risk of heart disease, diabetes, and colon cancer.
- Found in, for example, vegetables, fruit, whole grain products, legumes, and nuts.
