gain or other health, medical, or cultural requirements.
Function of nutrients in food in your body
-they provide energy
-they promote growth and development
-they regulate body processes

The nutrients in food provide the fuel your body used to carry on all its day-to-day activities.
They promote growth and development…
Nutrients enable your body to grow, develop, and repair itself. Lack of key nutrients can result in
stunted growth, physical and mental disables, and general ill health.

Categories of nutrients
Carbohydrates
Proteins
Fats
Vitamins
Minerals
Water
Macronutrient
Carbohydrates, proteins, fats
An essential nutrient that provides energy and is require in relatively large amounts for normal
growth and development
Micronutrient
Vitamins, minerals, water
An essential nutrient that is required in relatively small amounts for normal growth and
development
All equally important in your diet
Proteins
Each protein is made up of small units called Amino acids
- there are 22 different amino acids
- AA perform a wide variety of functions within the body including building and repairing cells
necessary for growth
- cells within the body can build some of their own proteins from Amino acids
Can be used as a source of energy
Two categories of Amino acids
Essential and non-essential
Essential
The body can only make some essential amino acids. However, it does not make them at a rate
fast enough to meet the body’s need
It is essential that you eat them from food
Types of protein
Complete, partially complete, incomplete
