1. Food and
Ingredients

2. Content
• Proteins
• Fats
• Carbohydrates
• Vitamins
• Minerals
• Water
• Artificial Additives

3. Proteins

4. What are proteins?
• Chains of amino acids
• 20 different kinds of amino acids
• Millions of different structures and
connections could be constructed
• Needed to build new cells

5. Structure and compounds
• Primary (sedimentary) structure
• Secondary structure
• Tertiary structure
• Quaternary structure

6. Functions
• Construction material
• Transport function
• Structural function
• Constructional function
• Protection and prevention
• Proteins as enzymes

7. Protein-rich food
• Lentils ( contain 23,5% of proteins )
• Tuna, peas and Roquefort cheese ( 23%)
• Chicken breast( 22.8%)
• Cold turkey cut, cooked ham,
sardines in oil,…

8. Fats

9. What are fats?
• Main nutrients
• Also called lipids
• Complex and simple lipids
• Animalistic and herbal substrates
• Saturated fatty acids
• Unsaturated fatty acids
• multiple saturated fatty acids

10. Functions
• Energy storage
• Build-up of cell membranes
• Flavour carrier
• Intake of fat-soluble vitamins
• A few fats:
• Phospholipids
• Carotinoids
• Oils

11. Carbohydrates

12. What are carbohydrates?
• Basic modules of our organism
• Main nutrients
• Classification:
• monosaccharides
• disaccharides
• polysaccharides

13. Functions
• Provide energy when deconstructed
• Storage of energy
• Energy resource
• Backup-function
• Are modules of substances defining blood
types

14. Vitamins

15. What are vitamins?
• Essential to maintain bodily functions
• Not storable
• Already small amounts affect the body
• Two different kinds:
– Water - soluble vitamins (e.g. Vit B, Vit C)
– Fat - soluble vitamins (e.g. Vit A, Vit D)

16. Vitamins
• Fulfill different functions
• Can mostly be found in fruit and vegetables
• Deficiencies and overuse can cause diseases
– Exception: Surplus of water-soluble
vitamins can easily be exuded

17. Minerals

18. What are minerals?
• Inorganic substances
• Indestructible but leachable
• Only small amounts are needed

19. Funtions
• Construction material of teeth and bones
• Active substances
– Protection of the nerv fibres
– Regulating the ph-value of the blood

20. Classification
• Minerals are divided into two categories
through their consumed quantities:
– quantitative elements (like
Calcium, Magnesium,…)
– trace elements (like
Iron, Fluorine, Cobalt,…)

21. Water
• Water forms about 70% of the human body
• Water dissolves substances in cells
• Metabolic reactions stop without water
• Blood must contain a lot of water
• Substances are transported around the body

22. Artificial Additives

23. What are additives?
• Optical enhancements
• Harmful for the body over the years

24. Austrian
Food Pyramid

25. The Austrian National Nutrition
Action Plan - NAP
• Diversified and balanced
• Reduction of over-, under- and
malnutrition
• reduction of the rising overweight and
obesity rates by 2020
• main focus since 2011 is the school catering
• target groups: infants, children, juveniles
