Energy needs
Everyday a person uses up energy .the
amount you use partly depends on how old
are you , which sex are you
And what job you do.

for making protein such as hemoglobin, insulin and antibodies( which help
to kill harmful pathogens . The sources of protein are meat ,fish ,eggs ,
peas and lentils

Vitamins and minerals .
Vitamins are organic substances
which only needed in certain
amounts . If u do not have
enough of a vitamin , you may get
a deficiency disease
Minerals are inorganic substances.
Once again only small amounts of
mineral are needed . If we consume
more minerals than needed it may lead
to various health conditions such as
gastrointestinal issues
Fibre
Fibre helps to keep the alimentary canal
working properly.
The alimentary canal is the part of the
digestive system through which food
passes through as it moves from the
mouth to the anus . Food moves
through the alimentary canal of
peristalsis.
The muscles are stimulated to do this
when there is food in the alimentary
canal. Soft food do not stimulate
muscles very much. The muscles are
stimulated to do this when there is
harder less digestible like fibre. So
fibre help to keep the alimentary canal
working properly
