The  difference between  brown  and  white  flour  is that  white flour(refined  wheat flour) contain  only the endosperm,whereas in whole-grain(unrefined
whole wheat flour) all of the grain (bran,germ and endosperm )is intact and  utiilized when
processing  flour from  whole- grains.So consuming whole-grain whole
wheat flour in our  daily diet is highly
advantageous as  nothing is lost in the
process of making the flour.The  textured, brownish colour of whole grain flour
is due to keeping the  bits and pieces
of  the grains intact( without discarding them) in the
process of making flour. 
Whole-grain whole
wheat flour is  a healthy,full-flavored
flour, fortified  with vitamins, minerals
and protein.Whole-grain  wheat flour is
more nourishing than their counterpart , the  refined white flour. Refined white flour  does
not,contain the macronutrients  of the
wheat's bran and germ,especially protein and fibre,like whole-grain flour
does. Whole grain has a good amount  of
vitamins like calcium , iron,and minerals like selenium.
Unlike white
refined flour,whole grain flour  does
not raise sugar levels very quickly.So it makes  a better choice for diabetics who
wish to keep their sugar levels under control.
However you
cannot store the whole grain flour  for
longer periods as it has  a shorter shelf
life than white flour. The oil content is much higher in the  whole grain wheat flour
causing it to spoil quickly,
if  it is not  stored in cool places such as a refrigerator.
