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.
