Whole Wheat Indian Bread- Chapati/ roti

Whole Wheat Flour : ( From Wiki)
Wheat Grain is one of the healthy grain.
Whole wheat flour is more nutritious than refined white flour, although in a process called food fortification, some micronutrients are added back to the white flour (required by law in some jurisdictions). Fortified white wheat flour does not, however, contain the macronutrients of the wheat's bran and germ (especially fiber and protein). Whole wheat is a good source of calcium, iron, fiber, and other minerals like selenium
Nutrition Facts Of Whole Wheat Flour:

 The roti or chapati made out of regular, bleached and enriched atta is not so healthy. Whole wheat flour contains good amount of fiber that is very good for diabetic patients.


Note: The main Drawback of this atta is it's life period, It cannot stay for many days like refined one. So, always change atta atleast once a month.

MY question is:
