water & protein
Micronutrients : vitamins minerals & fibres
,

Outline the functions of macro /micronutrients
Macro nutrients : nutrients that provide the
energy
necessary to maintain
bodily functions
during rest & physical activity
Micronutrients facilitate
energy transfer and tissue
:
synthesis
carbohydrates : provide fuel for the body and act
as
energy storage
Proteins :
repair and of muscle tissue
growth
vital
Lipids : protects organs and helps with thermo -
regulation
water :
transportation and
thermoregulation
Fibre helps the
:
digestive system
Vitamins :
energy release from macronutrients
Minerals : elements found in food that are used by
the
body
